Description

Technical Field

[0001] The present invention relates to the technical field of cold chain logistics fresh-keeping boxes, and in particular to an intelligent logistics system based on fresh food distribution. Background Art

[0002] When transporting fresh produce, hooks are usually used to hang them, which can make full use of the vertical space of the transport vehicle. If some soft and easily deformed fresh produce, such as poultry, are piled up, they are easily squeezed and their shapes are destroyed during transportation. Hanging them with hooks can separate them from each other and keep their natural shapes. However, during transportation, the hung fresh produce will shake with the bumps of the vehicle, and adjacent fresh produce will collide with each other, affecting the quality of the product.

[0003] To this end, a Chinese patent with authorization announcement number CN115783475B discloses a fresh pork cold chain logistics preservation box and a method of using the same. Through the guide rails and moving device, the meat hook can use the balls and limit blocks set on the inside of the moving device to easily adjust the position when the live pig is not hooked. With the cooperation of the arc-shaped rubber bumps and friction pads, the moving device and the meat hook can effectively perform friction positioning after the live pig is hooked, thereby improving the transportation stability of the live pig.

[0004] However, the above equipment can only shake the sauce-fried products to a certain extent. When the road surface is bumpy and the overall length of the products is long, during the shaking process, although the tops of adjacent products will not touch, the bottoms of the products will still collide, thus affecting the quality of the products.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes the function of supporting fresh products through a frame, an upper connecting mechanism, a lower connecting mechanism and a winding mechanism. After hanging the fresh products, the fresh products are tightened by the first elastic member and the second elastic member. During the transportation of fresh products, if the shaking amplitude is large, the first elastic member and the second elastic member are stretched, and when the tension sensor senses that the tension exceeds the threshold, the rotary drive component controls the first connecting rope to tighten and reduce the shaking amplitude of the fresh products. When the shaking amplitude of the fresh products is reduced, the rotary drive component releases a section of the first connecting rope to reduce the elongation amplitude of the first elastic member and the second elastic member. This solves the problem that the bottoms of adjacent fresh products in the traditional logistics system will collide with each other due to the shaking during transportation.

[0018] 2. The present invention realizes the function of storing the second hook through the column, the first bracket and the third hook. The first hook and the second hook are both in a free state when not connected to the fresh product. When storing the first hook, the operator can drive the first shaft to rotate by rotating the drive assembly, and the first shaft drives the first roller to rotate to reel in the first connecting rope, thereby limiting the shaking of the first hook. The second connecting rope cannot be reeled in, so a column and a first bracket are provided on the frame. When storing the second hook, the operator pulls the second hook, and the second elastic member stretches under the action of the tension, and then hangs the second hook on the third hook on the first bracket to limit the movement of the second hook. Improve the stability of the second hook during transportation.

[0019] 3. The present invention realizes the function of quickly adjusting the height of the first hook through the first rotating handle, the sensing component and the connecting component. Before putting the fresh product on, the operator first rotates the first rotating handle, and the torque transmitted by the first rotating handle and the first rotating shaft overcomes the friction force on the first roller, controls the rotation of the first roller, and adjusts the height of the first hook, so that the operator can hang the fresh product on the first hook more conveniently.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 4 : An intelligent logistics system based on fresh food delivery, comprising a frame 1, an upper connecting mechanism 2, a lower connecting mechanism 3 and a winding mechanism 4; the upper connecting mechanism 2 comprises a first rotating shaft 21, a first connecting rope 22, a first elastic member 23 and a first hook 24, the first rotating shaft 21 is rotatably arranged on the frame 1, a first rotating roller 211 is sleeved on the first rotating shaft 21, the first connecting rope 22 is wound around the first rotating roller 211, and a tension sensor 221 is arranged on the first connecting rope 22, and two ends of the first elastic member 23 are respectively connected to the tension sensor 221. The device 221 is connected to the first hook 24; the lower connecting mechanism 3 includes a second rotating shaft 31, a second connecting rope 32, a second elastic member 33 and a second hook 34, the second rotating shaft 31 is rotatably set on the frame 1, and a second roller 311 is sleeved on the second rotating shaft 31. The second connecting rope 32 is wound around the second roller 311, and the two ends of the second elastic member 33 are respectively connected to the second connecting rope 32 and the second hook 34; the winding mechanism 4 includes a rotating driving component 41, and the rotating driving component 41 is used to drive the first rotating shaft 21 to rotate.

[0033] The present invention realizes the function of supporting the fresh product 5 through the frame 1, the upper connecting mechanism 2, the lower connecting mechanism 3 and the winding mechanism 4. After the fresh product 5 is hung, the fresh product 5 is tightened by the first elastic member 23 and the second elastic member 33. During the transportation of the fresh product 5, if the shaking amplitude is large, the first elastic member 23 and the second elastic member 33 are stretched, and when the tension sensor 221 senses that the tension exceeds the threshold, the rotary drive component 41 controls the first connecting rope 22 to tighten and reduce the shaking amplitude of the fresh product 5. When the shaking amplitude of the fresh product 5 is reduced, the rotary drive component 41 releases a section of the first connecting rope 22 to reduce the elongation amplitude of the first elastic member 23 and the second elastic member 33. This solves the problem that the bottoms of adjacent fresh products 5 in the traditional logistics system will collide with each other during transportation due to shaking. The frame 1 is provided with a controller for human-machine interaction, and the tension sensor 221 and the rotation drive assembly 41 are electrically connected to the controller; in the working state, the operator first hangs the top of the fresh product 5 on the first hook 24, and then connects the second hook 34 below to the bottom of the fresh product 5, and then controls the first rotating shaft 21 to rotate through the rotation drive assembly 41, and the first rotating shaft 21 drives the first roller 211 to rotate, controls the first connecting rope 22 to reel up, and the first connecting rope 22 pulls the first elastic member 23 and the first hook 24 to move up. Under the action of tension, the first elastic member 23 and the second elastic member 33 are continuously extended, and when the tension sensor 221 senses that the tension reaches the specified range, it feeds back a signal to the controller, and the controller stops the rotation drive assembly 41. During transportation, the fresh product 5 shakes under the action of inertia. During the shaking process, the first elastic member 23 and the second elastic member 33 are further stretched due to the tension. When the tension sensor 221 senses that the tension exceeds the threshold, the rotation drive assembly 41 controls the first rotating shaft 21 to further rotate, controls the first connecting rope 22 to be reeled up, and increases the tension provided by the first connecting rope 22, thereby reducing the shaking amplitude of the fresh product 5 and avoiding collision between adjacent fresh products 5.

[0034] Reference Figure 2 and Figure 3 : A column 11 is provided on the frame 1, a first bracket 111 is provided on the column 11, and a third hook 112 for connecting with the second hook 34 is provided on the first bracket 111.

[0035] The present invention realizes the function of storing the second hook 34 through the column 11, the first bracket 111 and the third hook 112. The first hook 24 and the second hook 34 are both in a free state when they are not connected to the fresh product 5. When storing the first hook 24, the operator can drive the first rotating shaft 21 to rotate by the rotating driving component 41, and the first rotating shaft 21 drives the first roller 211 to rotate to reel in the first connecting rope 22, thereby limiting the shaking of the first hook 24. However, the second connecting rope 32 cannot be reeled in. For this reason, the column 11 and the first bracket 111 are provided on the frame 1. When storing the second hook 34, the operator pulls the second hook 34, and the second elastic member 33 stretches under the action of the tension, and then hangs the second hook 34 on the third hook 112 on the first bracket 111 to limit the movement of the second hook 34. Improve the stability of the second hook 34 during transportation.

[0036] Reference Figure 1 and Figure 4 : The winding mechanism 4 includes a sensing component 42 and a connecting component 43; the sensing component 42 is arranged on the frame 1, and the sensing component 42 is used to sense the tension exerted on the first hook 24; a first rotating handle 212 is sleeved on the first rotating shaft 21; in the working state, when the fresh product 5 is hung on the first hook 24, the driving end of the rotating driving component 41 is connected to the first rotating shaft 21 through the connecting component 43.

[0037] The present invention realizes the function of quickly adjusting the height of the first hook 24 through the first rotating handle 212, the sensing component 42 and the connecting component 43. Before the fresh product 5 is set, the first hook 24 is not subjected to additional tension, the connecting component 43 is not connected to the driving end of the rotating drive component 41 and the first rotating shaft 21, and the first rotating shaft 21 is in a free state. At this time, the first roller 211 is only subjected to the friction force, which prevents the first hook 24 from moving down by itself under the action of gravity. At this time, the operator first rotates the first rotating handle 212, and the torque transmitted by the first rotating handle 212 and the first rotating shaft 21 overcomes the friction force on the first roller 211, controls the rotation of the first roller 211, and adjusts the height of the first hook 24, so that the operator can more conveniently hang the fresh product 5 on the first hook 24. When the fresh product 5 is hung on the first hook 24, the gravity on the fresh product 5 applies a pulling force to the first hook 24. After the sensing component 42 senses the pulling force, the driving end of the rotating drive component 41 and the first rotating shaft 21 are connected through the connecting component 43. Then the controller sends a signal to the rotating drive component 41, and the rotating drive component 41 drives the first rotating shaft 21 to rotate through the connecting component 43, thereby controlling the first connecting rope 22 to be reeled up.

[0038] Reference Figure 4-Figure 6: The sensing component 42 includes a second bracket 421, a support 422, a third elastic member 423, a third bracket 424 and a third rotating shaft 425; the second bracket 421 and the third bracket 424 are arranged on the frame 1; the support 422 is movably arranged on the frame 1, the first rotating shaft 21 and the first roller 211 are both rotatably arranged on the support 422, and the docking ring 431 is rotatably connected to the support 422; the third elastic member 423 is arranged on the support 422, and the third elastic member 423 is connected to the second bracket 421; the third rotating shaft 425 is rotatably arranged on the third bracket 424, and the driving end of the rotation drive component 41 is transmission-connected to the third rotating shaft 425; when the fresh product 5 is hung on the first hook 24, the support 422 moves downward, the axis of the first rotating shaft 21 is colinear with the axis of the third rotating shaft 425, and the first rotating shaft 21 is transmission-connected to the third rotating shaft 425 through the connecting component 43.

[0039] The present invention realizes the function of sensing the stress state of the first hook 24 through the second bracket 421, the support 422, the third elastic member 423, the third bracket 424 and the third rotating shaft 425. A guide rail for controlling the moving range of the first rotating shaft 21 is provided on the frame 1. A cushion block 426 is slidably installed on the guide rail of the frame 1, and a fifth elastic member 427 is provided on the cushion block 426. The two ends of the fifth elastic member 427 are respectively connected to the cushion block 426 and the support 422. Through the elastic force provided by the fifth elastic member 427, after the operator removes the fresh product 5 from the first hook 24, the support 422 is controlled to reset. When the fresh product 5 is hung on the first hook 24, the first hook 24 is subjected to an additional tensile force, the third elastic member 423 is extended under the tensile force, the support 422 moves downward, and then the first rotating shaft 21 and the first roller 211 are driven to move downward through the support 422. Until the first rotating shaft 21 moves to the end of the guide rail, the axis of the first rotating shaft 21 is in line with the axis of the third rotating shaft 425, and the connecting assembly 43 connects the first rotating shaft 21 and the third rotating shaft 425. Then, the rotation driving assembly 41 drives the third rotating shaft 425 to rotate, and the third rotating shaft 425 drives the first rotating shaft 21 to rotate through the connecting assembly 43, so as to control the retraction and extension of the first connecting rope 22.

[0040] Reference Figure 4 , Figure 6 and Figure 7 : The connecting component 43 includes a docking ring 431 and a connecting ring 432; the docking ring 431 is movably sleeved on the first rotating shaft 21, and the docking ring 431 can slide along the axial direction of the first rotating shaft 21; the connecting ring 432 is sleeved on the third rotating shaft 425; the frame 1 is provided with a control component 44 for controlling the movement of the docking ring 431.

[0041] The present invention realizes the function of connecting the first rotating shaft 21 and the third rotating shaft 425 when the axis of the first rotating shaft 21 and the axis of the third rotating shaft 425 are collinear through the docking ring 431, the connecting ring 432 and the control assembly 44. When the fresh product 5 is hung on the first hook 24, the support 422 moves downward under the action of gravity, and the docking ring 431 is driven to move downward through the support 422, and during the downward movement, the control assembly 44 controls the docking ring 431 to move toward the connecting ring 432. When the axis of the first rotating shaft 21 and the axis of the third rotating shaft 425 are collinear, the docking ring 431 abuts against the connecting ring 432, and through the static friction between the docking ring 431 and the connecting ring 432, when the rotation drive assembly 41 drives the third rotating shaft 425 to rotate, the third rotating shaft 425 drives the connecting ring 432 to rotate, and the connecting ring 432 drives the docking ring 431 and the first rotating shaft 21 to rotate, thereby driving the first rotating roller 211 to rotate, and controlling the retraction and release of the first connecting rope 22.

[0042] Reference Figure 4 , Figure 6 and Figure 7 A docking post 4311 is movably provided on the docking ring 431, and a fourth elastic member 4312 is provided on the docking post 4311. Two ends of the fourth elastic member 4312 are respectively connected to the docking post 4311 and the docking ring 431; a docking groove 4321 cooperating with the docking post 4311 is provided on the connecting ring 432.

[0043] The present invention realizes the function of stably connecting the docking ring 431 and the connecting ring 432 when the docking ring 431 and the connecting ring 432 are in contact with each other through the docking column 4311, the fourth elastic member 4312 and the docking groove 4321. When the docking ring 431 and the connecting ring 432 are in contact with each other, if the docking column 4311 and the docking groove 4321 are misaligned, the docking column 4311 is squeezed by the connecting ring 432, and the fourth elastic member 4312 contracts under the pressure. With the rotation of the connecting ring 432, when the docking groove 4321 is aligned with the docking column 4311, the docking column 4311 is engaged with the docking groove 4321 under the elastic force of the fourth elastic member 4312, and the connecting ring 432 drives the docking ring 431 to rotate synchronously through the plug-in cooperation between the docking column 4311 and the docking groove 4321.

[0044] Reference Figure 4-Figure 7 : The control component 44 includes an oblique protrusion 441, a fixed block 442 and a connecting block 443; the oblique protrusion 441 is arranged on the support 422; the fixed block 442 is arranged on the frame 1, and the oblique protrusion 441 and the fixed block 442 are slidably matched; the connecting block 443 is slidably arranged on the support 422, and the two ends of the third elastic member 423 are respectively connected to the connecting block 443 and the second bracket 421.

[0045] The present invention realizes the function of controlling the movement of the docking block through the oblique protrusion 441, the fixed block 442 and the connecting block 443. When the support 422 moves downward, a squeezing effect occurs between the oblique protrusion 441 on the support 422 and the fixed block 442, and the inclined surface of the oblique protrusion 441 and the inclined surface on the fixed block 442 guide and push the docking block to move toward the connecting block 443. When the axis of the first rotating shaft 21 and the axis of the third rotating shaft 425 are colinear, the docking ring 431 on the support 422 abuts against the connecting ring 432.

[0046] Reference Figure 2 , Figure 4 and Figure 5 : The rotation drive assembly 41 includes a rotation driver 411, a worm 412 and a worm wheel 413; the rotation driver 411 is arranged on a third bracket 424; the worm 412 is rotatably arranged on the third bracket 424, and the driving end of the rotation driver 411 is transmission-connected to the worm 412; the worm wheel 413 is sleeved on the third rotating shaft 425, and the worm wheel 413 is meshingly connected to the worm 412.

The rotating driver 411 is preferably a servo motor, and the rotating driver 411 is electrically connected to the controller. In the working state, the operator hangs the fresh product 5 on the first hook 24, and then connects the second hook 34 to the fresh product 5. Then the controller sends a signal to the rotating driver 411, and the rotating driver 411 drives the worm 412 to rotate after receiving the signal, and the worm 412 drives the worm wheel 413 meshed with it to rotate, and the worm wheel 413 drives the third rotating shaft 425 and the docking ring 431 to rotate, and after the docking column 4311 on the docking ring 431 is plugged and matched with the docking groove 4321 on the connecting ring 432, the connecting ring 432 drives the docking ring 431 to rotate, and the first rotating shaft 21 is driven to rotate through the docking ring 431.

[0048] Reference Figure 5 : One end of the worm 412 is sleeved with a second rotating handle 414.

[0049] The present invention realizes the function of manually driving the worm 412 to rotate through the second rotating handle 414. The rotating driver 411 is preferably a servo motor without self-locking capability.

There are at least two upper connecting mechanisms 2 and lower connecting mechanisms 3 on the frame 1, and a column 11 is arranged between adjacent upper connecting mechanisms 2. The baffle 12 arranged on the column 11 makes the fresh product 5 contact with the baffle 12 when shaking, and then pushes the baffle 12. The damping rod 13 contracts under pressure and absorbs the kinetic energy of the baffle 12, providing damping for the movement of the baffle 12, thereby buffering the impact caused by the shaking of the fresh product 5.

[0052] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
