Description

Technical Field

[0001] The present application relates to the technical field of automatic fruit box packaging, and in particular to a box positioning device for automatic fruit box packaging. Background Art

[0002] Automatic fruit boxing and packaging improves packaging efficiency, reduces labor costs, and ensures the safety and freshness of fruit during transportation and storage. This process includes sorting, washing, drying, and automatic boxing and packaging. Automated boxing and packaging can complete the fruit packaging process continuously and rapidly, significantly improving packaging efficiency, reducing reliance on manual labor, and lowering labor costs. Furthermore, the high precision of automated equipment reduces scrap and further reduces production costs.

[0003] The entire system for automatic fruit packing currently in use is shown in the attached manual. Figure 1 As shown, the specific operation process is as follows: the picked fruits are placed on the conveyor roller for conveyance, and when conveyed to the bottom of the automatic identification device, the position of each fruit is identified by the camera system, and then the fruit is continued to be conveyed to the bottom of the grabbing mechanism at the rear. After the position information of each previously identified fruit is transmitted to the grabbing mechanism (the grabbing mechanism has a soft rubber suction head, which can suck the fruit with negative pressure by connecting the driving air pipe), the fruits on the conveyor roller are picked up in turn and placed in the packaging box placed on the conveyor belt next to it, and then placed in sequence, as shown in FIG. Figure 2 As shown, the automatic packing operation of fruits is realized, which can greatly improve the working efficiency and realize the automation of packaging.

[0004] During the entire automatic fruit boxing operation, the boxes are manually assembled into a box structure and then placed on a conveyor belt for transportation. When the box reaches the position corresponding to the grabbing mechanism, the conveyor belt stops running (the conveyor roller is equipped with a sensor that is positioned with the box), and then the grabbing mechanism grabs the fruit and places it in the box in sequence. In this process, the position of the box is uncertain after it is manually placed on the conveyor belt, and there is a left-right deviation, such as Figure 4-5 As shown, when the fruits are subsequently placed, there is a position deviation between the fruits and the box body, which makes it impossible to place the fruits accurately in the box body, resulting in the need for manual re-arrangement in the later stage, increasing the operation process and packaging costs. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a box positioning device for automatic fruit packing, which can adjust the position of the box so that the box and the conveyor belt are in a parallel placement state, and can accurately place the fruits in the box, avoiding the fruits falling out of the box and the subsequent increase in the need for manual re-organization.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a box positioning device for automatic fruit packing, the automatic fruit packing includes a gripping mechanism, and a conveyor belt for placing the box is provided on one side of the gripping mechanism, characterized in that: the box positioning device is arranged on the conveyor belt, includes a positioning member in contact with the box, and the positioning member is in sliding contact with the box under the driving action of the conveyor belt.

[0007] Preferably, the positioning member is a positioning plate corresponding to the grabbing mechanism and symmetrically fixed on both sides of the conveyor belt, and the positioning plate sequentially has an open section with an arc-shaped structure, a straight section, and a tail section with an arc-shaped structure.

[0008] Preferably, rollers that are in rolling contact with the box body are arranged at intervals on the positioning plate.

[0009] Preferably, driving ridges that contact the rear end of the box body are arranged at intervals on the conveyor belt.

[0010] The beneficial effect of the present application is that the box positioning device adjusts the position of the box through the contact between the positioning component and the box, so that the box and the conveyor belt are placed in parallel. After the box is transported to the position corresponding to the grasping mechanism, the fruit can be accurately placed in the box, avoiding the fruit falling out of the box and the subsequent increase in the need for manual re-organization.

[0023] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Refer to the attached Figures 1 to 10 The box positioning device for automatic fruit boxing shown in the figure includes a grabbing mechanism, and a conveyor belt 2 is provided on one side of the grabbing mechanism to place the box 1. When the conveyor belt 2 transports the box to the position corresponding to the grabbing mechanism and stops, the grabbing mechanism grabs the fruits conveyed on the conveyor rollers one by one and places them into the box. In order to solve the problem of manual box placement causing deviation during the entire boxing process, which affects the accurate placement of fruits into the box, as shown in the figure. Figure 6 As shown, the present application is provided with a box positioning device on the conveyor belt 2, which includes a positioning component in contact with the box 1. The position of the box is adjusted through the contact between the positioning component and the box, so that the box 1 and the conveyor belt 2 are in a parallel placement state. After the box 1 is transported to the position corresponding to the grasping mechanism, the fruit can be accurately placed in the box 1, avoiding the fruit falling out of the box and the subsequent increase in the process of manual re-organization.

[0025] In order to ensure that the box can still be transported by the conveyor belt 2 after packing, the positioning member is in sliding contact with the box 1 under the driving action of the conveyor belt 2 to avoid the positioning member from blocking the box transportation, thereby realizing continuous box packing operation.

[0026] Specifically, such as Figure 6-7As shown, the positioning member is a positioning plate 3 that corresponds to the grasping mechanism and is symmetrically fixed on both sides of the conveyor belt 2, and the positioning plate 3 has an open section 3a of an arc structure, a straight section 3b, and a tail section 3c of an arc structure in sequence. The open section 3a increases the distance between the symmetrical positioning plates 3, so that the manually placed boxes can smoothly enter between the symmetrical positioning plates 3, and then the box 1 is gradually guided along the arc surface of the open section 3a to a state parallel to the conveyor belt 2. After the box 1 continues to enter the straight section 3b, the straight section 3b further guides the box 1 to a state parallel to the conveyor belt 2, and stops at this position to pack the fruit. After the packing is completed, the conveyor belt 2 continues to transport the box 1 through the tail end 3c and continues to transport, waiting for the next box 1 to enter between the symmetrical positioning plates 3 again for guiding and positioning, and the packing operation.

[0027] Since the box body 1 is usually made of paper and has a relatively small body weight when not loaded with fruits, when the box body 1 contacts the positioning plate 3, the contact friction will affect the smooth movement of the box body 1. Therefore, in order to solve this problem, Figure 8-9 As shown, rollers 4 are spaced apart on the positioning plates 3 and are in rolling contact with the box 1. When the box 1 enters between the symmetrical positioning plates 3, the side walls of the box 1 come into rolling contact with the rollers 4, thereby reducing frictional resistance and allowing the box 1 to smoothly move to the position corresponding to the gripping mechanism when not loaded with fruit.

[0028] Furthermore, since the box body 1 is made of paper, the width of the box body will increase when it is wet, and the symmetrical positioning plates 3 will be blocked from contact with the box body 1, and it is still difficult to enter between the symmetrical positioning plates 3. Therefore, in order to solve this problem, Figure 10 As shown, drive ribs 5 are spaced apart on the conveyor belt 2 to contact the rear end of the box 1. When the box 1 is placed on the conveyor belt 2 for transportation, the rear end of the box 1 contacts the drive ribs 5, which mechanically drive the box 1 forward, thereby overcoming the problem of the box 1 being affected by moisture and having large contact resistance with the symmetrical positioning plates 3, which affects the smooth movement of the box 1. The drive ribs 5 can preferably be connected to the conveyor belt 2 with a magnetic attraction structure, which facilitates the adjustment of the spacing between the drive ribs 5 according to the specifications of different boxes 1. It also facilitates the conveyor belt 2 to be used for conveying other items after the drive ribs 5 are removed.

[0029] Preferably, the positioning plate 3 on each side is hinged at the side of the conveyor belt 2, and a driving roller 4 is provided at the hinge to press against the outer wall of the box ( Figure 10 The torsion spring (not shown in the figure) with the action indicated by the arrow a) can further eliminate the contact gap between the roller 4 and the box body 1, thereby improving the positioning accuracy of the box body 1.

[0030] The principle of this application is as follows: the box positioning device includes positioning plates 3 disposed on both sides of a conveyor belt 2 for conveying a box 1, rollers 4 spaced apart on the positioning plates 3, and driving ridges 5 spaced apart on the conveyor belt 2. When positioning the box, the assembled box 1 is placed on the conveyor belt 2 and transported by the conveyor belt 2. After the box 1 reaches the positioning plates 3, the spacing between the symmetrical positioning plates 3 is increased by the open section 3a, allowing the manually placed box to smoothly enter between the symmetrical positioning plates 3. The box 1 is then gradually guided along the arc surface of the open section 3a until it is parallel to the conveyor belt 2. After the box 1 continues to enter the straight section 3b, the straight section 3b further guides the box 1 to a parallel position with the conveyor belt 2, and the fruit is stopped at this position for box packing. After box packing is completed, the conveyor belt 2 continues to transport the box 1 through the tail end 3c and continues to transport, waiting for the next box 1 to enter between the symmetrical positioning plates 3 again for guidance and positioning, and the box packing operation.

[0031] During the transportation of the box 1, if the box 1 is deformed or affected by moisture, the rear side of the box 1 contacts the driving ridge 5 to overcome the rolling friction of the roller 4, so that the box 1 can be smoothly transported to the position corresponding to the grasping mechanism.

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