Description

Technical Field

[0001] This application relates to the technical field of fruit packing and boxing, and particularly to a position alignment device for automatic fruit packing and boxing. Background Art

[0002] After fruits mature, they can increase the economic income of growers through external sales. In large-scale single-fruit planting areas, due to the large planting area, a large number of fruits are harvested during the mature season. To avoid fruit rot, it is necessary to pack and box the fruits in a short period. After boxing, they can be transported for external sales to reduce economic losses.

[0003] To improve the packing and boxing efficiency of fruits, currently, the picked fruits are automatically packed through the automatic packing equipment as shown in the attached Figure 1 specification. The specific working process is as follows: The picked fruits are poured onto the conveyor belt and then transported under the position recognition system to obtain the position information of each fruit. Then, they are transported under the fruit picking system and picked up according to the obtained position information and automatically placed in a packing box on one side, thus realizing the automatic fruit packing operation, which can greatly improve the fruit packing and external sales operations in a short time and reduce economic losses.

[0004] Currently, after the picked fruits are poured on one side of the conveyor belt, it usually causes the accumulation of fruits ( Figure 2 shown on the right side). In the accumulated state, it affects the accurate recognition of subsequent position information and the subsequent picking operation of individual fruits, resulting in incomplete fruit position picking information, omissions during subsequent picking, and extrusion damage to fruits during mechanical picking in the accumulated state, increasing economic losses. At the same time, the shapes of fruits are diverse. For example, kiwifruits are long and strip-shaped. If they are placed on the conveyor belt with deflection ( Figure 2 shown on the left side), the picking suction head with a structure adapted to it cannot stably achieve fitting and picking, and there is a problem of fruit dropping and damage after picking, which will also increase the economic losses of fruit boxing. Summary of the Invention

[0005] Aiming at the above existing problems, this application aims to provide a position alignment device for automatic fruit packing and boxing, which can place the accumulated fruits individually, solve the influence of accumulation on position information acquisition and subsequent accurate picking; and adjust the positions of the separated individual fruits so that the fruits are in a state aligned with the rubber suction head of the picking system, thereby ensuring the stability of suction during suction and avoiding fruit dropping and damage.

[0006] To achieve the above object, the technical solution adopted by the present application is as follows: A position alignment device for automatically packing fruits in boxes, including a conveyor belt for receiving a number of fruits, characterized in that: a separating mechanism for separating individual fruits is provided on the conveyor belt, and an alignment mechanism for adjusting the placement position of the fruits.

[0007] Preferably, the separating mechanism is separating wheels that rotate and are evenly spaced on the conveyor belt. The surface of the separating wheel is an arc-shaped surface structure that fits the fruits, and a fruit placement space is jointly formed between the longitudinally adjacent separating wheels along the advancing direction of the conveyor belt.

[0008] Preferably, the alignment mechanism is a flexible belt that fits the separating wheels on the bottom side of the conveyor belt and drives the separating wheels to rotate.

[0009] Preferably, the alignment mechanism is a driving wheel that fits the separating wheels on the bottom side of the conveyor belt and drives the separating wheels to rotate.

[0010] The beneficial effect of the present application is that the position alignment device can realize placing the stacked fruits individually through the separating mechanism, solving the influence on obtaining position information during stacking and accurate picking later; and through the alignment mechanism, the position of the separated individual fruits can be adjusted so that the fruits are in a state of being aligned with the rubber suction head of the picking system, thereby ensuring the stability of suction during suction and avoiding the dropping and damage of the fruits.

[0021] In order to enable those of ordinary skill in the art to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Refer to the Figures 1-9 A position alignment device for automatically packing fruits in a box as shown, which includes a conveyor belt 1 for receiving a number of fruits. Currently, after the picked fruits are poured at one end of the conveyor belt 1, they are conveyed by the conveyor belt 1, and subsequent operations such as obtaining the position information of the fruits and picking and packing are carried out.

[0023] To solve the problem that the accumulation of fruits on the conveyor belt 1 affects the subsequent operations, and the problem that the deviation of the fruit position affects the stability of later picking, as Figures 3-6 shown, a separation mechanism for separating single fruits and an alignment mechanism for adjusting the placement position of the fruits are provided on the conveyor belt 1. Among them, through the separation mechanism, the piled-up fruits can be placed individually, solving the influence on the acquisition of position information and accurate picking later; and through the alignment mechanism, the separated single fruits can be position-adjusted so that the fruits are in a state of being aligned with the rubber suction head of the picking system, thereby ensuring the stability of suction during suction and avoiding the dropping and damage of the fruits.

[0024] Specifically, as Figure 3 shown, the separation mechanism is a separation wheel 2 that rotates and is evenly distributed on the conveyor belt 1. The surface of the separation wheel 2 is an arc-shaped surface structure that fits the fruits, and the space 2a for placing fruits is jointly formed between the longitudinally adjacent separation wheels 2 along the advancing direction of the conveyor belt 1. Among them, after the fruits are poured onto the conveyor belt 1, the fruits are embedded in the placement space 2a formed by the longitudinally adjacent separation wheels 2 due to their gravity, as Figure 3 shown, realizing the separation of single fruits, thereby solving the influence of the accumulation of fruits on the conveyor belt 1 on the acquisition of position information and picking. At the same time, the arc-shaped surface structure of the separation wheel 2 not only facilitates the sliding and embedding of the fruits, but also realizes the fitting and positioning with the fruits, avoiding the displacement of the fruits relative to the separation wheel 2 due to the uneven surface of the fruits, and the disadvantage that the subsequent acquisition of position information and the picking position are deviated and cannot be accurately picked.

[0025] After the above separation of fruits, the fruits are fitted and embedded in the fruit placement space 2a to realize the position alignment of the fruits. In order to further actively align the fruits, this application is realized through the following two embodiments:

[0026] Embodiment 1

[0027] As Figure 4 shown, the alignment mechanism is a flexible belt 3 that fits against the bottom side of the conveyor belt 1 and drives the separator wheel 2 to rotate. The flexible belt 3 is in frictional contact with the bottom side of the separator wheel 2. During the process of the conveyor belt 1 driving the separator wheel 2 to move forward, after the separator wheel 2 comes into contact with the flexible belt 3, the separator wheel 2 is driven to rotate through frictional contact, and at the same time drives the fruit to rotate. When the fruit is in a rotating state, the adjustment of its placement position can be realized, so as to realize the alignment operation of the placement position. Thus, in the subsequent picking operation, the rubber suction head can be completely suction-attached to the surface of the fruit, improving the suction stability and solving the problem of fruit dropping and damage.

[0028] Embodiment 2

[0029] As Figure 5 shown, the alignment mechanism is a driving wheel 4 that fits against the bottom side of the conveyor belt 1 and drives the separator wheel 2 to rotate. The driving wheel can preferably be connected to a driving motor, and the driving wheel 4 can actively drive the rotation of the separator wheel 2. Compared with Embodiment 1, it can drive the situation where the fruit is larger in size and difficult to be driven by the friction of the flexible belt 3.

[0030] Furthermore, as Figures 7-8 shown, in the case where the fruit is poured too fast, there may still be a problem of accumulation on the separator wheel 2. Therefore, under the driving action of Embodiments 1 and 2 on the separator wheel 2, driving the fruit to rotate can drive the piled-up fruit on the upper layer to shift. Figure 9 As shown in the above effect, the problem of fruit accumulation on the separator wheel 2 can be further avoided.

[0031] The principle of this application is: after the fruit is poured onto the conveyor belt 1, the fruit is embedded in the placement space 2a formed by the longitudinally adjacent separator wheels 2 due to its gravity, realizing the separation of individual fruits; at the same time, through the driving of the separator wheel 2 by the flexible belt 3 or the driving wheel 4, the fruit is driven to rotate. When the fruit is in a rotating state, the adjustment of its placement position can be realized, so as to realize the alignment operation of the placement position. When driving the fruit to rotate, the piled-up fruit on the upper layer can be driven to shift, and further, the problem of fruit accumulation on the separator wheel can be avoided.

[0032] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
