Description

Technical Field

[0001] The utility model relates to the technical field of pre-prepared food production equipment, in particular to a pre-prepared food stacking device. Background Art

[0002] Pre-prepared meals are convenient dishes that are prepared using modern standardized assembly line operations. The raw materials are processed hygienically and scientifically, and the processed dishes are then packaged. When needed, they can be eaten directly after a simple heating step.

[0003] In modern, standardized pre-prepared meal packaging lines, after bagging the pre-prepared meals, multiple bags need to be placed into boxes, which are then stacked vertically before being transferred to cold storage for storage. Currently, pre-prepared meal packaging lines typically use palletizers to neatly stack the boxes in a predetermined pattern, which are then transferred using handling tools. While this improves material handling efficiency and accuracy to a certain extent, the distance between the palletizers and the conveyor belts and handling tools means that the process from stacking to transfer takes considerable time. Furthermore, the transfer process requires manual labor, which consumes manpower and increases production costs. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a pre-prepared meal stacking device to solve the problem that the process from stacking to transporting the pre-prepared meal packaging boxes is relatively time-consuming and the transport work is labor-intensive.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] The pre-prepared food stacking device includes a bracket, an intermittent conveyor belt, a limiting mechanism, a lifting platform, and a lifting mechanism; the intermittent conveyor belt passes through the bracket and is used to intermittently convey the pre-prepared food packaging boxes; the limiting mechanism is installed on the top of the bracket on both sides outside the intermittent conveyor belt; the lifting platform is set below the intermittent conveyor belt; the lifting mechanism is installed at the bottom of the bracket and connected to the lifting platform; when the intermittent conveyor belt conveys the pre-prepared food packaging box to the top of the lifting platform and pauses, the lifting platform is raised by the lifting mechanism to lift the pre-prepared food packaging box, and the pre-prepared food packaging box is restricted from descending by the limiting mechanism.

[0007] As an optional solution, the intermittent conveyor belt is provided with a strip opening along its length; the lifting platform is arranged in the strip opening and extends below the intermittent conveyor belt.

[0008] As an optional solution, guardrails located outside the intermittent conveyor belt are fixedly connected to both sides of the upper surface of the bracket, and the limiting mechanism is installed on the guardrails.

[0010] As an alternative solution, both the bracket and the lifting platform are double-layer structures with upper and lower layers, and the upper and lower layers of the bracket and the lifting platform are connected by two connecting rods.

[0011] As an alternative solution, two baffles are provided at both ends of the upper layer of the lifting platform, and chamfers are provided at the inner edges of the tops of the baffles.

[0012] As an alternative solution, the lifting mechanism is a screw jack, the nut of the screw jack is fixedly connected to the lifting platform, and the screw rod of the screw jack is vertically rotatably connected to the bracket.

[0013] Due to the adoption of the above technical solutions, the present utility model will have the following beneficial effects:

[0014] For the prefabricated vegetable stacking device provided by the present utility model, when the intermittent conveyor belt conveys the prefabricated vegetable packaging box to directly above the lifting platform and pauses, the lifting platform is lifted by the lifting mechanism to jack up the prefabricated vegetable packaging box, and the limiting mechanism is used to restrict the prefabricated vegetable packaging box from descending; repeating the above steps can vertically stack multiple prefabricated vegetable packaging boxes together until the restriction of the limiting mechanism is released, so that the vertically stacked prefabricated vegetable packaging boxes descend to the intermittent conveyor belt along with the lifting platform for conveying.

[0027] Please refer to Figure 1-5 , in an embodiment of a prefabricated food stacking device of the present utility model, the prefabricated food stacking device includes a bracket 1, an intermittent conveyor belt 2, a limiting mechanism 3, a lifting platform 4, and a lifting mechanism 5;

[0028] Among them, both the bracket 1 and the lifting platform 4 are double-layer structures with upper and lower layers. The upper and lower layers of the bracket 1 and the lifting platform 4 are connected by two spaced connecting rods. On both sides of the upper surface of the upper layer of the bracket 1, guardrails 11 in the shape of a ladder are fixedly connected.

[0029] In addition, the intermittent conveyor belt 2 passes through the bracket 1. Specifically, the intermittent conveyor belt 2 passes above the upper layer of the bracket 1 and between the two guardrails 11. The intermittent conveyor belt 2 is provided with a strip-shaped opening along its length direction. The prefabricated food packaging box 6 is placed on the intermittent conveyor belt 2 and straddles the strip-shaped opening. The intermittent conveyor belt 2 can intermittently convey the prefabricated food packaging box 6. The intermittent conveyor belt 2 (also known as the "intermittent running conveyor belt") is a conveyor belt system, which is characterized by having intermittent pauses or starts during transportation. This type of conveyor belt is usually used in scenarios where items need to be processed batch by batch, such as in the assembly, packaging, or inspection processes on a production line.

[0030] Furthermore, the limiting mechanism 3 is installed on the top of the bracket 1 on both outer sides of the intermittent conveyor belt 2. Specifically, the limiting mechanism 3 is installed on the guardrails 11 in the shape of a ladder to limit the descent of the prefabricated food packaging box 6; the lifting platform 4 is arranged below the intermittent conveyor belt 2. Specifically, the upper layer of the lifting platform 4 is arranged in the strip-shaped opening, and the two connecting rods of the lifting platform 4 extend downward to the intermittent conveyor belt 2. The lifting platform 4 is used to lift the prefabricated food packaging box 6; the lifting mechanism 5 is installed at the bottom of the bracket 1 and is connected to the lifting platform 4 to lift and lower the lifting platform 4. Specifically, the lifting mechanism 5 can be set as a screw jack. The nut of the screw jack is fixedly connected to the lifting platform 4 through screws. The two ends of the screw of the screw jack are respectively rotatably connected vertically to the upper layer of the bracket 1, and the main body of the screw jack is installed on the lower layer of the bracket 1. Since the nut is restricted from rotating by the lifting platform 4, the main body drives the screw to rotate, and the rotation of the screw can drive the nut to move up and down, thereby lifting and lowering the lifting platform 4.

[0031] Please refer to Figure 6, in this embodiment, when the intermittent conveyor belt 2 conveys the prefabricated food packaging box 6 to directly above the lifting platform 4 and pauses, the lifting platform 4 is lifted by the lifting mechanism 5 to jack up the prefabricated food packaging box 6, and the descending of the prefabricated food packaging box 6 is restricted by the limiting mechanism 3; repeating the above steps can stack multiple prefabricated food packaging boxes 6 vertically together until the restriction of the limiting mechanism 3 is released, so that the vertically stacked prefabricated food packaging boxes 6 descend to the intermittent conveyor belt 2 with the lifting platform 4 for conveying.

[0032] Specifically, the limiting mechanism 3 includes a sleeve 31 and an electric push rod 32; the sleeve 31 is rotatably sleeved on the cross bar of the guardrail 11, and limiting plates 33 extending towards the inner side of the guardrail 11 are fixedly connected to both ends of the sleeve 31, and a connecting plate 34 extending towards the outer side of the guardrail 11 is fixedly connected to the middle of the sleeve 31; one end of the electric push rod 32 is rotatably connected to the connecting plate 34, and the other end of the electric push rod 32 is rotatably connected to the upper surface of the upper layer of the bracket 1; when it is necessary to restrict the descending of the prefabricated food packaging box 6, control the electric push rod 32 to extend to push the connecting plate 34 to rotate upwards, thereby driving the limiting plate 33 to rotate downwards to the horizontal state, and when it is necessary to release the restriction on the prefabricated food packaging box 6, control the electric push rod 32 to shorten to pull the connecting plate 34 to rotate downwards, thereby driving the limiting plate 33 to rotate upwards to the vertical state. The distance between the limiting plates 33 of the two limiting mechanisms 3 in the horizontal state is less than the width of the prefabricated food packaging box 6, and the distance in the vertical state is greater than the width of the prefabricated food packaging box 6, so as to achieve the effect of restricting and releasing the restriction on the descending of the prefabricated food packaging box 6.

[0033] Specifically, two baffles 41 can be provided at both ends of the upper layer of the lifting platform 4. The two groups of baffles 41 are distributed along the conveying direction of the prefabricated food packaging box 6. The inner edge of the top of the baffle 41 is provided with a chamfer, which can play a guiding role when the lifting platform 4 lifts the prefabricated food packaging box 6; the distance between the two groups of baffles 41 is slightly greater than the length of the prefabricated food packaging box 6.

[0034] It should be noted that a PLC controller connecting the lifting mechanism 5 and the electric push rod 32 can be set, and the forward and reverse rotation of the lifting mechanism 5 and the telescoping of the electric push rod 32 can be controlled according to the time interval of the start and stop of the intermittent conveyor belt 2.

[0035] The usage method or working principle of the present utility model is as follows:

[0036] When the intermittent conveyor belt 2 conveys the prefabricated food packaging box 6 to directly above the lifting platform 4 and pauses, the PLC controller turns on the lifting mechanism 5 to rotate the lead screw forward to lift the lifting platform 4 to jack up the prefabricated food packaging box 6 until the height of the bottom of the prefabricated food packaging box 6 is higher than the limiting plate 33. The PLC controller stops the rotation of the lead screw and controls the electric push rod 32 to extend to make the limiting plate 33 rotate downward to a horizontal state. Then the PLC controller rotates the lead screw in reverse to lower the lifting platform 4 to its original position. During the process of the prefabricated food packaging box 6 descending with the lifting platform 4, it is restricted from descending by the limiting plate 33 and remains on the limiting plate 33.

[0037] When the next prefabricated food packaging box 6 is conveyed to directly above the lifting platform 4 and pauses, the PLC controller turns on the lifting mechanism 5 to rotate the lead screw forward to lift the lifting platform 4 to jack up the prefabricated food packaging box 6 until the prefabricated food packaging box 6 abuts against the bottom surface of the prefabricated food packaging box 6 above it. The PLC controller controls the electric push rod 32 to shorten to make the limiting plate 33 rotate upward to a vertical state. During this process, the lifting platform 4 can jack up two prefabricated food packaging boxes 6 until the height of the lower prefabricated food packaging box 6 is higher than the limiting plate 33. The PLC controller stops the rotation of the lead screw and controls the electric push rod 32 to extend to make the limiting plate 33 rotate downward to a horizontal state. Then the PLC controller rotates the lead screw in reverse to lower the lifting platform 4 to its original position. The two prefabricated food packaging boxes 6 are restricted from descending by the limiting plate 33 and remain on the limiting plate 33 during the process of descending with the lifting platform 4. Repeating the above steps multiple times can stack multiple prefabricated food packaging boxes 6 vertically together.

[0038] When the last prefabricated food packaging box 6 jacks up the multiple prefabricated food packaging boxes 6 above it, the limiting mechanism 3 is not used to restrict its descent, so that the stacked prefabricated food packaging boxes 6 descend with the lifting platform 4 to the intermittent conveyor belt 2 for conveying.

[0039] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
