[0022] The purpose of this invention is to provide a material handling and conveying device to solve the problems existing in the prior art, so that material particles can be arranged in sequence and avoid stacking during transportation.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1 like Figures 1 to 7 As shown, this embodiment provides a material handling and conveying device, including at least two vibrators 4 and at least two material handling troughs. The material handling troughs are arranged sequentially from high to low, with the highest trough receiving materials and the lowest trough supplying materials to the next processing step. Each material handling trough is connected to a vibrator 4, and the internal cross-section of the material handling trough is V-shaped. The vibrators 4 can cause the material handling trough to vibrate back and forth along the centerline of the trough, and the vibration frequency of each vibrator 4 can be adjusted. In this embodiment, the V-shaped material handling trough allows the materials to be gradually arranged according to their weight under the action of the vibrators 4, with the heavier side facing down and the lighter side facing up. The orientation of the materials can be adjusted according to processing needs, making it suitable for material handling in automated fruit processing equipment, especially for the material handling in automated areca nut processing, allowing sliced ​​areca nuts to be conveyed with the cut surface facing up.

[0025] As an optional solution, this embodiment provides three sorting troughs, namely a first sorting trough 1, a second sorting trough 2, and a third sorting trough 3. One end of the second sorting trough 2 is located below one end of the first sorting trough 1, and the other end is located above one end of the third sorting trough 3. Vertical gaps are provided between the first sorting trough 1 and the second sorting trough 2, and between the second sorting trough 2 and the third sorting trough 3. The other end of the first sorting trough 1 is a receiving end, and a closed baffle 5 is provided in the trough of the receiving end to prevent the material from falling during vibration. In this embodiment, the height difference of each sorting trough is used to separate the fruits and solve the problem of stacking of granular materials. Especially for sliced ​​areca nuts, the posture can be corrected according to their center of gravity and the shape of the material channel, so as to achieve the effect of the cut surface facing upward.

[0026] As an optional solution, the vertical gap in this embodiment is at least 1 mm, and preferably 10 mm, to facilitate the adjustment of the posture of the granular material under the action of gravity.

[0027] As an optional solution, in this embodiment, the lengths of the first material feeding trough 1, the second material feeding trough 2, and the third material feeding trough 3 are all at least greater than the length of a single largest material, and the depth of the trough is at least the height of a single largest material, providing sufficient space to facilitate the arrangement of materials one by one in the material feeding trough.

[0028] As an optional solution, in this embodiment, the first material feeding trough 1, the second material feeding trough 2 and the third material feeding trough 3 are each provided with at least two sequentially connected stepped surfaces 6 of different depths. The depth difference between the two stepped surfaces 6 is at least 1 mm and does not exceed the length of the smallest material particle. In this embodiment, 5 mm is preferred. The height of the stepped surfaces 6 is set from high to low along the material transport direction, which facilitates the material to move forward under the action of vibration and gravity and adjust its posture.

[0029] As an optional solution, in this embodiment, a fixed plate 11 is provided at the bottom of the material handling trough. The upper end of the vibrator 4 is bolted to the fixed plate 11, and the lower end is bolted to a base 7 for easy disassembly and replacement. At least one material handling trough is provided with a chip discharge port 9. Since chips affect the core removal production efficiency, the more chips there are, the more time will be wasted on subsequent material identification and classification, and the slower the core removal efficiency will be, so a chip discharge port 9 is provided to discharge the chips.

[0030] As an optional solution, in this embodiment, the base 7 is provided with connecting seats 8 of different heights, and a vibrator 4 is connected to the connecting seat 8. The height of the connecting seat 8 matches the height of the corresponding material handling trough. The vibrator 4 is a linear vibrating feeder. The vibration frequency of each vibrator 4, set from high to low, gradually increases. By increasing the speed, the disordered fruits are arranged in an orderly manner, and the spacing between the fruits is increased to avoid material stacking and achieve single-fruit conveying. The different vibration frequencies of the vibrators 4 determine the forward speed of the material. The top surface of the connecting seat 8 can be set horizontally, or, depending on the actual working conditions, if the speed of the vibrator is already adjusted to the maximum speed and the material handling effect is still not good, the angle of the top surface of the connecting seat 8 can be changed to tilt it, thereby obtaining a greater conveying speed.

[0031] As an optional solution, in this embodiment, the upper end of the two adjacent material handling troughs is provided with a chip discharge port 9. The chip discharge port 9 is U-shaped and is supported by a chip discharge guide trough 10 below. The side wall of the chip discharge guide trough 10 is fixedly connected to one side of the base 7. The upper opening of the chip discharge guide trough 10 is inclined, and the lower opening is supported by a slag collection hopper. The size of the chip discharge port 9 is smaller than the width of the smallest material, so that the smallest material can pass through the chip discharge port 9 smoothly. In this embodiment, the chip discharge port 9 is designed according to the size of the fruit. Taking betel nut processing as an example, the opening size is usually a minimum width of 12mm and a minimum length of 8mm, which can discharge the slag during the transportation of betel nuts.

[0032] As an optional solution, in this embodiment, a detection device 14 is provided above the middle of each feeding trough, and a detection device 14 for detecting whether there is feeding is also provided on the feeding end of the highest feeding trough. The detection device 14 is a background suppression type diffuse reflection photoelectric sensor, which can accurately detect the target material in the presence of background interference. Products of different colors and different heights can be accurately identified.

[0033] As an optional solution, in this embodiment, the detection device 14 is connected to a protective shell 12 via a bracket 13, and the vibrator 4 and each material feeding trough are located inside the protective shell 12. The protective shell 12 is provided with a transparent observation window 15 and an inlet and outlet 16 of the slag collection hopper, which facilitates observation of the material condition and makes it convenient to replace the slag collection hopper.

[0034] As an optional solution, in this embodiment, each detection device 14 and each vibrator 4 is communicatively connected to a control unit. The control unit can control the start and stop of the vibrator 4 according to the detection signal of the detection device 14, and the control unit can also adjust the vibration frequency of the vibrator 4. In this embodiment, by coordinating the start and stop of each vibrator 4 with the material conveying, the effect of only one piece of material passing through the cross-section of the trough at a time is achieved. The control unit includes a delay function, which can set the start and stop delay of the vibrator 4. An appropriate delay can be selected and set according to the size of the material and its passing speed.

[0035] In this embodiment, the specific working process of the material conveying device, taking a three-layer material conveying trough as an example, is as follows: Each feeding trough is equipped with a detection device 14 to detect the presence of material, thereby controlling whether the vibrator stops vibrating. When the detection device 14 above the receiving end of the first feeding trough 1 detects material, each vibrator 4 starts working until the detection device 14 above the third feeding trough 3 detects material, at which point the third vibrator of the third feeding trough 3 stops working. When the material for the next process in the third feeding trough 3 is used up, a material shortage signal is sent to the control unit, which then controls the third vibrator to vibrate and feed material to the next process. When the detection device 14 above the third feeding trough 3 detects no material, it transmits a material shortage signal to the second vibrator according to the delay set by the control unit, causing it to vibrate and feed material until the detection device 14 above the third feeding trough 3 detects the arrival of material, at which point the second vibrator stops vibrating. This process continues, with the start-stop logic of the second vibrator being the same as that of the first vibrator. When the material on the third feeding trough 3 is transferred away, the detection device 14 on the third feeding trough 3 no longer detects material, and all three vibrators 4 of the feeding troughs start vibrating.

[0036] In this embodiment, the material handling and conveying device adopts a three-stage vibrator matched with a V-shaped material trough and sensor control to achieve the effects of changing fruit posture, arranging fruit, distributing fruit individually, and conveying. Its modular design makes it easy and quick to apply to various automated fruit processing equipment, especially areca nut processing equipment. It can realize the functions of fruit handling, arrangement, and conveying, and can be widely used on various automated fruit processing equipment.
