Description

Technical Field

[0001] This utility model belongs to the field of fruit sorting technology, specifically a weighing and receiving device for fruits. Background Technology

[0002] In the fruit sorting process, in addition to classifying the quality of the fruit, the subsequent packaging issue also needs to be considered. Each sorting port is generally equipped with a weighing component to remind employees or limit the weight standard. However, currently, there is a large height difference between the receiving position and the sorting port. For example, in the published technical document "CN212158769U, a continuous automatic weighing device for a fruit sorting machine", the attached diagram shows that the output end of the weighing conveyor belt 10 is equipped with a finished product box 11. However, the weighing conveyor belt 10 is set horizontally, while the finished product box is located below the end of the weighing conveyor belt. When the fruit initially falls, there is a large height difference between the fruit and the bottom of the finished product box, which can easily damage the fruit and affect its appearance. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please refer to Figures 1-4 ;

[0026] The fruit receiving device described in this utility model not only has a weighing function, but also reduces the drop between the fruit delivery device and the basket within the original capacity, thus reducing damage to the fruit; specifically, it includes a frame 1 and a placement rack 2, with a placement basket (not shown) on the placement rack 2, a weighing component 3 installed on the frame 1, the upper end of the placement rack 2 being rotatably connected to the frame 1, the frame 1 being rotatably connected to one end of the telescopic component 4, and the other end of the telescopic component 4 being rotatably connected to the placement rack 2.

[0027] Preferably, the frame 1 has a clearance space 12 on the side away from the placement rack 2 for connecting external equipment, which is usually a conveyor belt for delivering fruit, or a sorting outlet in a sorting machine, etc. In addition, the telescopic component 4 is a nitrogen spring, and there are two on each side. In addition, two mounting plates 13 are provided on both sides of the frame 1. The mounting plates 13 have several holes 14. In actual application, it is not certain what type of fruit will be sorted, and different fruits have different weights. Therefore, different models of telescopic components 4 will be selected, and the installation positions of different models of telescopic components 4 will also be different. The several holes 14 on the mounting plates 13 provide adjustment space for the telescopic components 4. After the telescopic component 4 is selected, one end of the telescopic component 4 is fixed by passing through the hole 14 with a connector, and the telescopic component 4 is rotatably connected to the mounting plate 13 through the connector.

[0028] In the initial state, supported by the telescopic component 4, the placement frame 2 rotates relative to the frame 1 and is in an upward tilted state, while the placement basket is also lifted on the placement frame 2. In this state, the distance between the output end of the external fruit delivery device and the bottom of the placement basket can be greatly shortened.

[0029] As more and more fruit is placed in the basket, the weight borne by the placement rack 2 also increases. The weight borne by the placement rack 2 exceeds the thrust output by the telescopic component 4, and this trend gradually expands as the number of fruits in the basket increases. Therefore, the placement rack 2 will gradually compress the telescopic component 4 and eventually straighten itself. Then, the current position of the placement rack 2 is fixed by the locking component 5 to avoid affecting the weighing and fruit collection. After that, the weighing component 3 passes through the placement rack 2 and comes into contact with the placement basket to obtain the weighing value. Before the predetermined weight value is reached, the fruit will continue to fall into the placement basket. After the predetermined weight value is reached, the fruit will stop falling or the staff will be notified to remove the placement basket. Of course, in this case, the fruit falling speed will not be too fast, allowing enough time for the staff to remove the basket.

[0030] Since the locking component 5 locks the placement rack 2, the placement rack 2 will not be lifted by the telescopic component 4 even after the placement basket is removed, thus avoiding injury to the staff. Afterwards, the empty placement basket is placed back on the placement rack 2, the locking of the placement rack 2 is released, the placement rack 2 loses pressure and is lifted back by the telescopic component 4 to return to its initial state before the fruit is received.

[0031] This utility model uses a telescopic component 4 to make the placement rack 2 initially tilted upwards, so that the placement basket can be closer to the fruit delivery device before receiving the fruit, which makes it easier to receive the fruit and avoids serious collisions caused by large fruit drop.

[0032] However, tilting the basket reduces the capacity of the fruit. As the weight of the basket increases, the position of the placement rack 2 relative to the frame 1 gradually decreases, eventually straightening the basket and restoring its normal fruit-receiving capacity. Then, the weighing component 3 can pass through the placement rack 2 and act on the bottom of the basket to perform the weighing operation.

[0033] Preferably, the frame is provided with an "L"-shaped movable position 11, and bearing seats 62 are provided on both sides of the upper end of the frame 1. The placement frame 2 is "L"-shaped so that it matches the movable position 11. Rotating shafts 61 are provided on both sides of the upper end of the placement frame 2. The rotating shafts 61 are rotatably connected to the bearing seats 62. Of course, bearings are provided in the bearing seats 62, and the bearings are connected to the rotating shafts 61.

[0034] In one embodiment of the present invention regarding the weighing component 3, in order to avoid the weighing component 3 obstructing the descent of the placement frame 2, or causing damage due to a collision between the placement frame 2 and the weighing component 3, the weighing component 3 is initially positioned out of reach of the placement frame 2. Specifically, it includes a cylinder 31, which is vertically installed at the bottom of the frame 1. The output end of the cylinder 31 is provided with a mounting plate 32, and a pressure sensor 33 is installed on the mounting plate 32. A bracket 34 is fixedly installed at the sensing end of the pressure sensor 33, and the bracket 34 can pass through the placement frame 2.

[0035] Preferably, the bottom of the placement rack 2 is composed of several first crossbars with gaps between them, while the bracket 34 is composed of several second crossbars, which are staggered with the first crossbars, so that the bracket 34 can extend out from the placement rack 2.

[0036] When the placement rack 2 is in the upright position, the cylinder 31 pushes all the components to move upward, and the bracket 34 extends out from the bottom of the placement rack 2 and abuts against the bottom of the placement basket. The weight of the placement basket is applied to the bracket 34 and finally acts on the pressure sensor 33.

[0037] Preferably, the shelf is provided with a plurality of buffer blocks 35, the buffer blocks 35 corresponding to the lower end face of the placement shelf 2.

[0038] The locking component 5 in this utility model has many implementations, such as clamping, hook limiting, etc., which can be achieved by existing technology. However, this embodiment provides a more convenient locking method, specifically including a movable plate 51, which is rotatably connected to the frame 1. A pedal 52 is provided at the lower end of the movable plate 51, and a slot 53 is provided at the upper end of the movable plate 51. A locking post 54 that cooperates with the slot 53 is provided on one side of the placement rack 2 to limit the lifting of the placement rack 2. It also includes a tension spring 55, one end of which is connected to the frame 1 and the other end is connected to the movable plate 51.

[0039] In one usage method, the movable plate 51 is initially tightened by the tension spring 55. Before locking, the movable plate 51 is rotated by manually stepping on the foot pedal, which stretches the tension spring 55 at the same time. After the placement frame 2 is rotated and aligned, the foot pedal is released, and the movable plate 51 is reset under the action of the tension spring 55. At the same time, the slot 53 moves closer to the locking post 54, and finally the two are locked together.

[0040] After the basket full of fruit is taken out, it will not pop out because the placement rack 2 is fixed by the locking component 5. Then, after the empty basket is placed on the placement rack 2, the card slot 53 is moved away from the card post 54 by stepping on the foot pedal, thereby unlocking.

[0041] In another usage, the upper end of the movable plate 51 is provided with an arc surface 56. In the initial state, the worker does not need to step on the foot pedal. Under the action of the tension spring 55, the movable plate 51 remains in an upright state. As the placement frame 2 gradually descends, the locking post 54 abuts against the arc surface 56 at the upper end of the movable plate 51. As the placement frame 2 assembly descends, it forms a compression on the upper end of the movable plate 51, causing the locking post 54 to slide along the arc surface 56. However, during the sliding process, the movable plate 51 will rotate and deflect, while stretching the tension spring 55. When the locking post 54 reaches the position corresponding to the slot 53, under the action of the tension spring 55, the movable plate 51 rotates in the opposite direction, causing the locking post 54 to enter the slot 53 to achieve locking.

[0042] In this embodiment of the utility model, photoelectric switches (not shown) are provided on both sides of the frame 1. When the placement frame 2 rotates and descends to the specified height, it will trigger the photoelectric sensor and be fixed by the locking component 5. The signal of the photoelectric sensor is transmitted to the system, and the system controls the weighing component 3 to operate.
