Description

Technical Field

[0001] This invention relates to the field of home appliance production line technology, and in particular to a refrigerator tilting and uprighting machine. Background Technology

[0002] With the development of society, freezers have become appliances used in various restaurants, shopping malls and other places. During the production process, due to the needs of the production process, freezers need to be erected from a horizontal position. Because freezers are large and heavy, it is very laborious to manually erect them. The labor cost on the production line is getting higher and higher. Long hours of work on the job cause workers to be fatigued, which makes the product quality more and more affected by subjective human factors and other reasons, and the efficiency is low.

[0003] The existing process for producing freezers, which requires manual turning of the boxes during the uprighting process, is no longer suitable for actual production. It not only fails to ensure product quality but also fails to reduce the workload of production line workers and lower production costs.

[0004] In addition, at present, after the above-mentioned production and processing steps, the refrigerated display cases are usually placed on pallets manually, and then transported and packaged.

[0005] Therefore, this invention addresses the aforementioned problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a refrigerator tilting and uprighting machine. First, the bottom plate conveying mechanism receives the bottom plate from an external conveying production line, and the bottom plate positioning mechanism positions the bottom plate on the bottom plate conveying mechanism. Then, the sliding seat driving mechanism drives the sliding seat to slide along the Y-axis of the base frame, causing the tilting frame to tilt. At this moment, the refrigerator conveying mechanism receives the refrigerator in a lying position from the external conveying production line. Next, the refrigerator positioning mechanism positions the refrigerator on the refrigerator conveying mechanism. Simultaneously, the pallet conveying mechanism receives the pallet from the conveying production line, and the pallet is located between the bottom plate and the bottom of the refrigerator, ensuring that the bottom plate, pallet, and bottom of the refrigerator are precisely aligned according to production requirements. Then, the sliding seat driving mechanism drives the sliding seat to slide and reset along the Y-axis of the base frame, causing the tilting frame to tilt and reset, thus tilting the refrigerator from a lying position to an upright position. At this moment, the bottom of the upright refrigerator is on the pallet, and the pallet is on the bottom plate. Finally, the bottom plate conveying mechanism transports the bottom plate containing the pallet and refrigerator to the next work step. Therefore, this invention features high automation, high work efficiency, stable and reliable structure, and high integration.

[0042] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] like Figure 1-13 As shown, the present invention provides an automatic tilting and uprighting machine for refrigerators, comprising:

[0044] Base frame 1;

[0045] A flip frame 2 includes a first frame 21 and a second frame 22 connected to corresponding ends of the first frame 21. The first frame 21 is provided with a bottom plate conveying mechanism 23 for conveying a bottom plate and a bottom plate positioning mechanism 24 for positioning the bottom plate on the bottom plate conveying mechanism 23. The second frame 22 is provided with a freezer conveying mechanism 25 for conveying a freezer and a freezer positioning mechanism 26 for positioning the freezer on the freezer conveying mechanism 25. A pallet conveying mechanism 27 for conveying a pallet is provided on the second frame 22 and located between the freezer conveying mechanism 25 and the bottom plate conveying mechanism 23. The second frame 22 is also provided with a pallet positioning mechanism for positioning the pallet. The structure of the pallet positioning mechanism is the same as that of the bottom plate positioning mechanism 24 or the freezer positioning mechanism 26.

[0046] A sliding seat 3 is slidably mounted on a base frame 1. A sliding seat guide assembly 31 is provided between the sliding seat 3 and the base frame 1, which enables the sliding seat 3 to slide along the Y-axis direction of the base frame 1. The sliding seat 3 is rotatably connected to the first frame 21.

[0047] Connecting rod 4, one end of which is rotatably connected to the base frame 1, and the other end of which is rotatably connected to the first frame 21;

[0048] A sliding seat drive mechanism 32 is provided between the sliding seat 3 and the base frame 1 to drive the sliding seat 3 to slide along the Y-axis direction of the base frame 1, thereby causing the flipping frame 2 to flip. In operation, the base plate conveying mechanism first receives the base plate from an external conveying production line, and the base plate positioning mechanism positions the base plate on the base plate conveying mechanism. Then, the sliding seat drive mechanism drives the sliding seat to slide along the Y-axis direction of the base frame to cause the flipping frame to flip (e.g., ...). Figure 4-6 As shown), at this moment, the freezer conveying mechanism receives the freezer in a lying position from the external conveying production line. Then, the freezer positioning mechanism positions the freezer on the freezer conveying mechanism. At the same time, the pallet conveying mechanism receives the pallet from the conveying production line, and the pallet is located between the bottom plate and the bottom of the freezer, so that the bottom plate, pallet, and bottom of the freezer are precisely aligned according to production requirements. Afterwards, the sliding seat driving mechanism drives the sliding seat to slide and reset along the Y-axis of the base frame so that the flipping frame flips and resets (as shown). Figure 1-3 As shown, the refrigerator, which is in a horizontal position, is flipped to an upright position. At this time, the bottom of the refrigerator is on a pallet, and the pallet is on the base plate. Finally, the base plate conveying mechanism transports the base plate containing the pallet and the refrigerator to the next work. Therefore, this invention has the characteristics of high automation, high work efficiency, and stable and reliable structure.

[0049] In this invention, the base plate is used to support the pallet and the freezer to facilitate subsequent transportation and avoid interference between the pallet and the conveyor production line.

[0050] The external conveying production line used in this invention is preferably a single line, which sequentially conveys the base plate, the pallet, and the freezer.

[0051] This invention integrates the base plate conveying mechanism, the refrigerator conveying mechanism, and the pallet conveying mechanism onto a flipping frame, which features high integration and compact structure. Furthermore, by flipping the flipping frame, the base plate conveying mechanism, the refrigerator conveying mechanism, and the pallet conveying mechanism can receive items from the same external conveying production line, simplifying the production line structure, reducing production line costs, and occupying less space.

[0052] like Figure 1-7 As shown, in order to improve the structural strength of the flip frame, the first frame 21 and the second frame 22 are vertically connected.

[0053] like Figure 1-6 As shown, the sliding seat drive mechanism 32 includes two sliding seat rotating wheels 321 spaced apart along the Y-axis of the base frame 1, and a sliding seat synchronization chain 322 that is drivenly connected to both sliding seat rotating wheels 321. One side of the sliding seat synchronization chain 322 is fixedly connected to the sliding seat 3. The sliding seat drive mechanism 32 also includes a sliding seat drive motor 323 for driving the corresponding sliding seat rotating wheels 321 to rotate. The sliding seat drive motor 323 can be an HF-SN152BJ-S100 Mitsubishi servo motor or a KA57TDRN90S4BE2 / HRP servo motor, etc.

[0054] like Figure 1 , 12 As shown, the base plate positioning mechanism 24 includes a base plate positioning bracket 241 mounted on the first frame 21. A base plate positioning block 242 is rotatably mounted on the base plate positioning bracket 241. A base plate positioning elastic element is provided between the lower end of the base plate positioning block 242 and the base plate positioning bracket 241, enabling the base plate positioning block 242 to remain in an upright position relative to the base plate positioning bracket 241. For example... Figure 1 As shown, the base plate positioning mechanism 24 is located at the input end of the base plate conveying mechanism 23. During the process of the base plate from the external conveying production line being conveyed to the base plate conveying mechanism 23, the base plate acts on the positioning end (upper end) of the base plate positioning block 242 to make the base plate positioning block 242 rotate relative to the base plate positioning bracket 241 to avoid the base plate, until the base plate separates from the base plate positioning block 242. Then, the base plate positioning elastic element pulls the lower end of the base plate positioning block 242 to make the positioning end (upper end) of the base plate positioning block 242 rotate and reset, that is, the base plate positioning block 242 is in an upright state relative to the base plate positioning bracket 241, as shown. Figure 1As shown, the bottom plate conveying mechanism 23 then conveys the bottom plate to the bottom plate positioning mechanism 24 until the corresponding end of the bottom plate abuts against the positioning end of the bottom plate positioning block 242. In some embodiments, the bottom plate positioning mechanism 24 has the same structure as the freezer positioning mechanism 26, and at this moment the bottom plate positioning mechanism 24 is located at the output end of the bottom plate conveying mechanism 23.

[0055] like Figure 12 As shown, the positioning end of the base plate positioning block 242 is provided with a guide slope 2421, which can prevent the base plate and the positioning end of the base plate positioning block 242 from getting stuck, and facilitate the base plate to push the positioning end of the base plate positioning block 242 so that the base plate positioning block 242 can rotate and avoid the base plate.

[0056] like Figure 4 , 13 As shown, the first frame 21 is also provided with a bottom plate fixing mechanism 29 for fixing the bottom plate relative to the bottom plate conveying mechanism 23. The bottom plate fixing mechanism 29 includes a bottom plate fixing cylinder 291 provided on the first frame 21, and a bottom plate fixing suction cup 292 is provided at the end of the cylinder rod of the bottom plate fixing cylinder 291. During the flipping process of the flipping frame, the bottom plate can be fixed relative to the first frame 21 by the bottom plate fixing mechanism 29; during the conveying process, the bottom plate fixing mechanism 29 cancels its action on the bottom plate.

[0057] like Figure 1 As shown, the freezer positioning mechanism 26 includes a freezer positioning cylinder 261 mounted on the second frame 22 and a freezer positioning stop 262 located at the end of the cylinder rod of the freezer positioning cylinder 261. In some embodiments, the structure of the freezer positioning mechanism 26 is the same as that of the base plate positioning mechanism 24.

[0058] like Figure 1-6 As shown, in order to make the sliding seat slide stably and smoothly, the sliding seat guide assembly 31 includes a guide rail provided on the base frame 1 and extending along the Y-axis direction of the base frame 1, and a guide slider slidably provided on the guide rail. The guide slider is fixedly connected to the sliding seat.

[0059] like Figure 1-7 As shown, the second frame 22 is also provided with a refrigerator auxiliary mechanism 28 for pushing the refrigerator away from the refrigerator conveying mechanism 25, thereby assisting the refrigerator to slide towards the bottom plate conveying mechanism 23 during the flipping process of the flipping frame 2. In the process of flipping the refrigerator from a horizontal to an vertical position, the refrigerator auxiliary mechanism prevents the refrigerator surface from contacting the refrigerator conveying mechanism, solving the problem of mutual wear between the two, providing a certain degree of protection, reducing maintenance and replacement costs, and also facilitating the refrigerator to slide towards the bottom plate conveying mechanism, thus improving conveying efficiency.

[0060] like Figure 1-7As shown, the refrigerator auxiliary mechanism 28 includes a lifting frame 281 that is movably mounted on the second frame 22. A refrigerator lifting drive mechanism 282 is provided between the lifting frame 281 and the second frame 22 to drive the lifting frame 281 to move relative to the second frame 22. The lifting frame 281 is provided with a plurality of auxiliary rollers 283 spaced apart to assist the refrigerator in sliding towards the base plate conveying mechanism 23 during the flipping process of the flipping frame 2. The refrigerator lifting drive mechanism 282 can be a hydraulic cylinder, a push cylinder, etc., or it can be driven by a drive motor in conjunction with a screw transmission mechanism to drive the lifting frame 281 to move up and down. When the refrigerator conveying mechanism 25 receives a refrigerator from an external conveying production line, the refrigerator lifting drive mechanism 282 drives the lifting frame 281 to move upward relative to the second frame 22, that is, the auxiliary rollers 283 push the refrigerator upward so that the refrigerator disengages from the refrigerator conveying mechanism 25. Then, the sliding seat drive mechanism drives the sliding seat to slide and reset along the Y-axis direction of the base frame so that the flipping frame flips and resets (e.g., ...). Figure 1-3 As shown), the refrigerator, which is lying down, is flipped to stand up. At this moment, the refrigerator in the stand-up position slides to the bottom plate conveying mechanism 23 until the bottom of the refrigerator is on the pallet and the pallet is on the bottom plate.

[0061] like Figure 5 As shown, to better drive the tilting frame to tilt, a tilting drive mechanism 33 is provided between the sliding seat 3 and the tilting frame 2 to assist in tilting the tilting frame 2. The tilting drive mechanism 33 includes a tilting drive cylinder 331 mounted on the sliding seat 3, a tilting drive rack 332 connected to the cylinder rod of the tilting drive cylinder 331, and a tilting drive gear 333 connected to the tilting frame 2. The tilting drive gear 333 can be driven by the tilting drive rack 332. In this embodiment, the tilting frame is tilted by the transmission cooperation between the tilting drive gears 333 and 332, which can meet the tilting drive force required by the tilting frame. It has the characteristics of constant instantaneous transmission ratio and high stability, stable and reliable structure, low noise, high transmission power, and high efficiency.

[0062] like Figure 6 , 11 As shown, to facilitate the smooth rotation of the flipping frame, a flipping auxiliary mechanism 11 is provided between the second frame 22 and the base frame 1 to assist in the rotation of the flipping frame 2. The flipping auxiliary mechanism 11 includes a flipping auxiliary drive cylinder 111 mounted on the base frame 1. The cylinder rod end of the flipping auxiliary drive cylinder 111 is provided with a flipping auxiliary push seat 112 that can cooperate with the second frame 22. When it is necessary to drive the flipping frame to rotate and reset, the flipping auxiliary drive cylinder 111 drives the flipping auxiliary push seat 112 to push the second frame 22 to rotate relative to the base frame 1 around the rotation axis between the second frame 22 and the sliding seat 3.

[0063] like Figure 6 , 11 As shown, in order to facilitate the smooth flipping of the frame, the flipping auxiliary drive cylinder 111 is inclinedly mounted on the base frame 1, and / or the flipping auxiliary push seat 112 is rotatably provided with a flipping auxiliary roller 113 that can cooperate with the second frame 22.

The freezer transport bracket 251 has end rotating wheels 252 at both ends. At least two middle auxiliary wheels 253 are spaced apart on the middle part of the freezer transport bracket 251. A middle drive wheel 254 is located on the middle part of the freezer transport bracket 251 and between the two middle auxiliary wheels 253. The middle drive wheel 254, the middle auxiliary wheels 253, and the end rotating wheels 252 are on different axes. The freezer transport mechanism 25 also includes a freezer transport synchronous belt 255 and a freezer transport drive motor 256 for driving the middle drive wheel 254 to rotate. The freezer transport synchronous belt 255 is sleeved on the two end rotating wheels 252 and the middle drive wheel 254.
