[0003] However, the aforementioned device cannot grasp and release the material trays, and cannot achieve the purpose of continuous transfer of several material trays. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a material tray transfer device.

[0005] The technical solution adopted in this utility model is as follows: A tray transfer device includes a guide rail frame, a frame mounted on the guide rail frame, a moving drive mechanism mounted on the frame for moving the frame on the guide rail frame, a tray picking device on the frame, the tray picking device including a tray picking frame, a lifting drive mechanism mounted on the frame, the output end of the lifting drive mechanism being connected to the tray picking frame, a plurality of rotating hooks rotatably connected to the tray picking frame, and a tilting drive mechanism mounted on the tray picking frame for driving the plurality of rotating hooks to tilt synchronously, the rotating hooks hooking the lowest tray.

[0006] After the stack of trays is conveyed to the tray-retrieving device, the lifting drive mechanism lowers the device, and several rotating hooks surround the stack of trays. The tilting drive mechanism then drives the rotating hooks around the trays to rotate synchronously, hooking the bottom tray. The lifting drive mechanism then raises the tray-retrieving device, and the moving drive mechanism moves the frame linearly to the braising tank, placing the stack of trays into the tank for braising. The process of removing the trays is the reverse of placing them in.

[0007] The tilting drive mechanism of this invention can drive several rotating hooks to rotate. When the rotating hooks rotate to hook the lowest tray, the tray can be lifted or moved linearly. When the rotating hooks rotate to avoid the trays, stacks of trays can be lowered, or interference with the trays can be avoided during the lowering of the tray-retrieving device. This invention can realize the gripping and releasing of trays, and combined with the lifting of the tray-retrieving device and the linear movement of the frame, it can realize the continuous transfer of several trays.

[0008] In a preferred embodiment of this invention, the moving drive mechanism includes a moving drive unit mounted on a frame. The output end of the moving drive unit is connected to a drive gear, and a rack is mounted on the guide rail. The drive gear and rack mesh. Several rollers are mounted on the frame and overlap the guide rail. When the moving drive unit drives the drive gear to rotate, the drive gear meshes with the rack on the guide rail, allowing the frame, lifting drive mechanism, and tray-retrieving device to move linearly along the guide rail as a whole. The rollers on both sides of the frame roll on the guide rail, thus supporting and guiding the frame.

[0009] In a preferred embodiment of this invention, the lifting drive mechanism includes a lifting drive unit mounted on a frame. The output end of the lifting drive unit is connected to a sprocket shaft, on which a drive sprocket is mounted. A driven sprocket is mounted at the lower end of the frame. A lifting chain is connected between the drive sprocket and the driven sprocket, and the tray-retrieving frame is fixed to the lifting chain. When the lifting drive unit drives the sprocket shaft to rotate, the sprocket shaft drives the lifting chain, which in turn drives the tray-retrieving frame to rise and fall, thus enabling the entire tray-retrieving device to rise and fall.

[0010] In a preferred embodiment of this invention, the sprocket shaft is equipped with two driving sprockets and two driven sprockets are mounted at the lower end of the frame. Two lifting chains are fixed to both sides of the tray-retrieving frame. The presence of lifting chains on both sides of the tray-retrieving device ensures smooth lifting and lowering.

[0011] As a preferred embodiment of this utility model, the tilting drive mechanism includes a tilting drive unit mounted on the tray retrieval frame. The output end of the tilting drive unit is connected to a bidirectional lead screw. The bidirectional lead screw has two helical sections with opposite thread directions. Nuts are threaded onto both helical sections. A moving rod is fixed on the nut. Several connecting rods are rotatably connected to the moving rod. A lever is fixed on the rotating hook. The other end of the connecting rod is rotatably connected to the end of the lever away from the rotating hook.

[0012] The tilting drive unit drives a bidirectional lead screw to rotate, which in turn drives two moving rods to move in opposite directions. These moving rods, via connecting rods, drive a lever to rotate, which in turn causes the rotating hook to rotate at a certain angle. Through holes are provided at the corners of the material trays, and the rotating hook passes through several of these through holes sequentially. A hook-shaped structure is located at the bottom of the rotating hook. When the rotating hook rotates, this hook-shaped structure can rotate to or move away from the underside of the material trays, thus supporting or releasing a stack of material trays.

[0013] In a preferred embodiment of this invention, a slide rail is fixed to the tray-retrieving frame, and a slider is fixed to the moving rod, with the slider fitted inside the slide rail. The slide rail guides the slider, ensuring that the moving rod can move smoothly in a straight line.

[0014] As a preferred embodiment of this utility model, the frame is connected with several limiting grooves, which limit the corners of a stack of material trays. During the lifting and lowering process of the tray-retrieving device, the limiting grooves can limit the corners of a stack of material trays, ensuring that the material trays are accurately stacked in the tray-retrieving device and that the rotating hook can accurately support or release the material trays when it rotates.

[0015] In a preferred embodiment of this invention, a water receiving tray is provided at the lower part of the frame, and an opening and closing drive mechanism for moving the water receiving tray is installed on the frame. During the process of gripping or lowering the material tray, the opening and closing drive mechanism moves the water receiving tray away from below the tray-retrieving device to prevent the water receiving tray from obstructing the passage of the material tray. During the movement of the frame, the opening and closing drive mechanism moves the water receiving tray to directly below the tray-retrieving device, so that water dripping from the material tray can be caught by the water receiving tray.

There are two water receiving trays, one of which is fixed to the upper side of the opening and closing chain, and the other is fixed to the lower side of the opening and closing chain.

[0017] During the opening and closing process, the upper and lower sides of the chain move in opposite directions, thus causing the two water receiving trays to move in opposite directions. When the two water receiving trays approach each other, the lower space of the tray-retrieving device is closed, and the water dripping from the trays falls into the water receiving trays; when the two water receiving trays separate, the lower space of the tray-retrieving device opens, allowing the stack of trays to pass through.

[0018] As a preferred embodiment of this utility model, a water receiving trough is fixed on the guide rail frame, and the water receiving trough is arranged along the moving path of the machine frame. A drain pipe is provided at the bottom of the water receiving tray, and the drain pipe extends into the water receiving trough. Water in the water receiving tray can be drained into the water receiving trough through the drain pipe, facilitating timely drainage. Because the water receiving trough is arranged along the moving path of the machine frame, the drain pipe on the water receiving tray can always correspond to the water receiving trough during the movement of the machine frame, enabling real-time drainage.

[0019] The beneficial effects of this utility model are as follows: The tilting drive mechanism of this invention can drive several rotating hooks to rotate. When the rotating hooks rotate to hook the lowest tray, the tray can be lifted or moved linearly. When the rotating hooks rotate to avoid the trays, stacks of trays can be lowered, or interference with the trays can be avoided during the lowering of the tray-retrieving device. This invention can realize the gripping and releasing of trays, and combined with the lifting of the tray-retrieving device and the linear movement of the frame, it can realize the continuous transfer of several trays.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0024] like Figure 1 As shown, the material tray transfer device of this embodiment includes a guide rail frame 1, a frame 2 is mounted on the guide rail frame 1, a moving drive mechanism 3 for driving the frame 2 to move on the guide rail frame 1 is installed on the frame 2, a tray picking device is provided on the frame 2, the tray picking device includes a tray picking frame 4, a lifting drive mechanism 5 is installed on the frame 2, the output end of the lifting drive mechanism 5 is connected to the tray picking frame 4, a plurality of rotating hooks 6 are rotatably connected on the tray picking frame 4, and a tilting drive mechanism 7 for driving the plurality of rotating hooks 6 to tilt synchronously is installed on the tray picking frame 4, the rotating hooks 6 hook the bottommost material tray 8.

[0025] After the stack of trays 8 is conveyed to the tray-retrieving device, the lifting drive mechanism 5 drives the tray-retrieving device to descend, and several rotating hooks 6 surround the stack of trays 8. The tilting drive mechanism 7 drives the several rotating hooks 6 around the trays 8 to rotate synchronously, and the rotating hooks 6 hook the bottom tray 8. The lifting drive mechanism 5 then raises the tray-retrieving device, and the moving drive mechanism 3 drives the frame 2 to move linearly to the braising tank position, placing the stack of trays 8 into the braising tank, so that the food in the trays 8 can be braised. The process of removing the trays 8 is the reverse of the process of placing the trays 8.

[0026] The tilting drive mechanism 7 of this invention can drive several rotating hooks 6 to rotate. When the rotating hooks 6 rotate to hook the lowest material tray 8, the material tray 8 can be lifted or moved linearly. When the rotating hooks 6 rotate to avoid the material tray 8, stacks of material trays 8 can be lowered, or interference with the material tray 8 can be avoided during the lowering of the tray-retrieving device. This invention can realize the gripping and releasing of material trays 8. Combined with the lifting of the tray-retrieving device and the linear movement of the frame 2, continuous transfer of several material trays 8 can be achieved.

[0027] Specifically, the moving drive mechanism 3 includes a moving drive unit 31 mounted on the frame 2. The output end of the moving drive unit 31 is connected to a drive gear 32. A rack 33 is mounted on the guide rail frame 1, and the drive gear 32 and rack 33 mesh. Several rollers 21 are mounted on the frame 2 and rest on the guide rail frame 1. When the moving drive unit 31 drives the drive gear 32 to rotate, the drive gear 32 meshes with the rack 33 on the guide rail frame 1, allowing the frame 2, lifting drive mechanism 5, and tray-retrieving device to move linearly as a whole on the guide rail frame 1. The rollers 21 on both sides of the frame 2 roll on the guide rail frame 1, thereby supporting and guiding the frame 2.

[0028] Specifically, the lifting drive mechanism 5 includes a lifting drive unit 51 mounted on the frame 2. The output end of the lifting drive unit 51 is connected to a sprocket shaft 52, on which a drive sprocket is mounted. A driven sprocket is mounted at the lower end of the frame 2. A lifting chain 53 is connected between the drive sprocket and the driven sprocket. The tray retrieval frame 4 is fixed to the lifting chain 53. When the lifting drive unit 51 drives the sprocket shaft 52 to rotate, the sprocket shaft 52 drives the lifting chain 53 to move, and the lifting chain 53 drives the tray retrieval frame 4 to rise and fall, thereby enabling the entire tray retrieval device to rise and fall.

[0029] The sprocket shaft 52 is equipped with two driving sprockets, and the lower end of the frame 2 has two driven sprockets. Two lifting chains 53 are fixed to both sides of the tray-retrieving frame 4. The tray-retrieving device has lifting chains 53 on both sides, ensuring smooth lifting and lowering.

[0030] Specifically, the tilting drive mechanism 7 includes a tilting drive unit 71 mounted on the tray retrieval frame 4. The output end of the tilting drive unit 71 is connected to a bidirectional lead screw 72. The bidirectional lead screw 72 has two helical sections with opposite thread directions. Nuts 73 are threaded onto both helical sections. A moving rod 74 is fixed on the nut 73. Two connecting rods 75 are rotatably connected to both ends of the moving rod 74. A lever 76 is fixed on the rotating hook 6. The other end of the connecting rod 75 is rotatably connected to the end of the lever 76 away from the rotating hook 6.

[0031] The invention comprises eight rotating hooks 6, eight levers 76, and eight connecting rods 75. Four rotating hooks 6 form a group, and one group of rotating hooks 6 surrounds a stack of material trays 8. This invention can simultaneously hook and lift two stacks of material trays 8 side by side, thereby improving the transfer efficiency of the material trays 8.

[0032] The tilting drive unit 71 drives the bidirectional lead screw 72 to rotate. The bidirectional lead screw 72 drives two moving rods 74 to move in opposite directions. The moving rods 74 drive the lever 76 to rotate via the connecting rod 75, thereby causing the lever 76 to rotate the rotating hook 6 by a certain angle. Through holes are provided at the corners of the material trays 8, and the rotating hook 6 passes through several through holes of the material trays 8 in sequence. A hook-shaped structure 61 is provided at the bottom of the rotating hook 6. When the rotating hook 6 rotates, the hook-shaped structure 61 can rotate to the underside of the material trays 8 or move away from the underside of the material trays 8, thus supporting or releasing a stack of material trays 8.

[0033] Furthermore, a slide rail 77 is fixed on the tray-retrieving frame 4, and a slider 78 is fixed on the moving rod 74, with the slider 78 fitted inside the slide rail 77. The slide rail 77 guides the slider 78, ensuring that the moving rod 74 can move smoothly in a straight line.

[0034] Furthermore, the frame 2 is connected to several limiting grooves 22, which limit the corners of a stack of trays 8. During the lifting and lowering process of the tray-retrieving device, the limiting grooves 22 can limit the corners of a stack of trays 8, ensuring that the trays 8 are accurately stacked in the tray-retrieving device and that the rotating hook 6 can accurately support or release the trays 8 when it rotates.

[0035] Furthermore, a water receiving tray 23 is provided at the lower part of the frame 2, and an opening and closing drive mechanism 9 is installed on the frame 2 to drive the water receiving tray 23 to move. During the process of grabbing or lowering the material tray 8, the opening and closing drive mechanism 9 drives the water receiving tray 23 to move away from below the tray-retrieving device to prevent the water receiving tray 23 from blocking the passage of the material tray 8. During the movement of the frame 2, the opening and closing drive mechanism 9 drives the water receiving tray 23 to move directly below the tray-retrieving device, so that the water dripping from the material tray 8 can be caught by the water receiving tray 23.

[0036] The opening and closing drive mechanism 9 includes an opening and closing drive unit 91 installed at one end of the frame 2. An opening and closing chain 92 is connected between the output end of the drive unit 91 and the other end of the frame 2. Two water receiving trays 23 are included; one tray is fixed to the upper side of the chain 92, and the other is fixed to the lower side. A guide rail 25 is installed at the bottom of the frame 2, and the water receiving trays 23 are mounted on the guide rail 25.

[0037] During the operation of the opening and closing drive unit 91 driving the opening and closing chain 92, the upper and lower sides of the opening and closing chain 92 move in opposite directions, thus causing the two water receiving trays 23 to move in opposite directions. When the two water receiving trays 23 approach each other, the lower space of the tray-retrieving device is closed, and the water dripping from the material tray 8 falls into the water receiving tray 23; when the two water receiving trays 23 separate, the lower space of the tray-retrieving device is opened, allowing the stack of material trays 8 to pass through.

[0038] Furthermore, a water receiving trough 11 is fixed on the guide rail frame 1, and the water receiving trough 11 is arranged along the moving path of the frame 2. A drain pipe 24 is provided at the bottom of the water receiving tray 23, and the drain pipe 24 extends into the water receiving trough 11. Water in the water receiving tray 23 can be drained into the water receiving trough 11 through the drain pipe 24, facilitating timely drainage. Because the water receiving trough 11 is arranged along the moving path of the frame 2, the drain pipe 24 on the water receiving tray 23 can always correspond to the water receiving trough 11 during the movement of the frame 2, enabling real-time drainage.

[0039] It should be noted that in this embodiment, the moving drive unit 31, the lifting drive unit 51, the tilting drive unit 71, and the opening and closing drive unit 91 are all motors and reducers.
