Description

Technical Field

[0001] This utility model relates to the technical field of material box storage and retrieval equipment, specifically to a conveyor belt type storage and retrieval structure for material boxes. Background Technology

[0002] In modern industrial production and logistics management, material bins serve as important carriers for various materials, and their storage and retrieval efficiency and management level directly affect the overall operational efficiency of production and logistics. Currently, common material bin storage and retrieval methods mainly include manual handling and automated storage and retrieval systems.

[0003] Manual handling relies heavily on manpower, requiring workers to manually move material boxes from storage areas to designated locations or return them from work areas to storage areas. This method has several drawbacks. On the one hand, it is labor-intensive, and workers are prone to fatigue from repetitive handling over long periods, leading to low work efficiency and high labor costs. On the other hand, the accuracy of manual operations is difficult to guarantee, and problems such as misplacement or omission of material boxes can easily occur, affecting the accuracy and continuity of production and logistics.

[0004] Automated storage and retrieval systems (AS / RS), such as palletizers, offer advantages like greater convenience and labor savings in storing and retrieving material bins. For instance, utility model patent CN214030889U discloses a novel palletizer comprising a column assembly, a beam assembly, and a chassis assembly. The column assembly is located on top of the chassis assembly, and the beam assembly is located on one side of the column assembly. This novel rotary palletizer features precise positioning, automated control, and requires no manual labor, resulting in high efficiency. It utilizes automated mechanical palletizing to ensure neat and orderly stacking of goods, has a small footprint, and can be programmed to operate in confined spaces, saving more space than traditional palletizing systems. The modular design of the entire machine facilitates easy disassembly and assembly, making it convenient for transportation.

[0005] While this technical solution has its advantages, most mechanized palletizers currently in use still have some shortcomings. For example, when picking up and placing materials, the mechanized palletizer relies on its own movement along the starting point to the target point and then back to the starting point to complete the operation. The entire process requires the palletizer to move back and forth twice (for example, the palletizer loads the material box at the starting point, moves to the palletizing point to stack it, and after stacking, the palletizer returns to the starting point to load the next material box). The whole process is relatively complex and cannot utilize a conveyor belt to directly transport the material box to the corresponding location for direct picking and placing at that location, which affects the picking and placing efficiency to some extent. In view of this, we propose a conveyor belt-type storage and retrieval structure for material boxes. Utility Model Content

[0006] The purpose of this invention is to provide a conveyor belt storage and retrieval structure for material boxes to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The conveyor belt storage and retrieval structure for the material bin includes a palletizer body. A conveyor belt assembly is provided on the front side of the palletizer body. The conveyor belt assembly includes two symmetrical U-shaped frames on the left and right. Two symmetrical uprights are fixedly installed at the bottom of the U-shaped frames. Bushings can be detachably installed in the front and rear side plates of the U-shaped frames. A rotating shaft is inserted and fitted between the two bushings. A belt roller is fixedly installed on the rotating shaft. The two belt rollers on the left and right are connected by a conveyor belt that is connected end to end. A servo motor is coaxially installed at the end of one of the rotating shafts.

[0009] Preferably, the front and rear side plates of the U-shaped frame are provided with through holes, and the bushing is located in the through hole and is inserted into the through hole;

[0010] Preferably, a fixing ring is fixedly installed on the end cylinder of the bushing, and the fixing ring is detachably connected to the U-shaped frame by a plurality of fastening screws;

[0011] The above two settings allow the bushing to be disassembled and replaced.

[0012] Preferably, the bushing has an inner assembly chamber, and a bearing is fixedly installed on the wall of the inner assembly chamber. The rotating shaft passes through the bearing and is rotatably connected to the bearing.

[0013] Preferably, a rectangular groove is provided in the shaft end body connected to the servo motor, and a rectangular rod is fixedly installed at the end of the output shaft of the servo motor.

[0017] This setting allows for the use of bottom pads of appropriate thickness for support and elevation when the bottom height is insufficient.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, by setting a conveyor belt assembly on the front side of the palletizer body, and the assembly consisting of a U-shaped frame, column, bushing, rotating shaft, belt roller, conveyor belt and servo motor, realizes the direct conveying of material boxes. The servo motor drives the rotating shaft to rotate, which drives the belt roller and conveyor belt to move, directly conveying the material boxes to the palletizing area. The palletizer can directly pick up and place the boxes at this area without having to move back and forth twice, simplifying the picking and placing process, greatly improving the picking and placing efficiency of material boxes, and enhancing the smoothness of the overall operation.

[0020] 2. This utility model sets the bushing as a detachable structure, which is connected to the U-shaped frame through a through hole and connected by a fixing ring and fastening screws. At the same time, the bearing installed in the bushing is rotatably connected to the shaft, realizing convenient disassembly and replacement of the bushing. When the bushing is worn or malfunctions, it can be quickly disassembled and replaced, reducing equipment maintenance time, ensuring the normal operation of the conveyor belt assembly, reducing equipment maintenance costs, and improving the reliability and service life of the equipment.

[0021] 3. This utility model achieves flexible adjustment of equipment installation by installing a fixed base at the bottom of the column and setting bottom pads.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a conveyor belt storage and retrieval structure for material boxes, including a palletizer body 1. A conveyor belt assembly 2 is provided on the front side of the palletizer body 1. The conveyor belt assembly 2 includes two symmetrical U-shaped frames 20 on the left and right. Two symmetrical columns 21 are fixedly installed at the bottom of the U-shaped frames 20. Bushings 24 can be detachably installed in the front and rear side plates of the U-shaped frames 20. A rotating shaft 27 is inserted and fitted between the two bushings 24. A belt roller 271 is fixedly installed on the rotating shaft 27. The two belt rollers 271 are connected by a conveyor belt 273 connected end to end. A servo motor 28 is coaxially provided at the end of one of the rotating shafts 27, so that the material box can be directly transported to the palletizing position through the conveyor belt 273. The servo motor 28 drives the rotating shaft 27 and the belt roller 271 to rotate, driving the conveyor belt 273 to run. This changes the traditional method of palletizers moving back and forth twice to pick up and place materials. The palletizer body 1 can directly pick up and place materials next to the conveyor belt 273, simplifying the process and significantly improving the material picking and placing efficiency.

[0031] In this embodiment, through holes 201 are provided on both the front and rear side plates of the U-shaped frame 20. The bushing 24 is located in the through hole 201 and is inserted into the through hole 201. A fixing ring 243 is fixedly installed on the end cylinder of the bushing 24. The fixing ring 243 is detachably connected to the U-shaped frame 20 by multiple fastening screws, so that the bushing 24 can be easily disassembled and replaced. When the bushing 24 is worn or damaged, the fastening screws can be quickly removed and the bushing 24 can be taken out for repair or replacement, reducing the downtime of the equipment due to bushing failure and ensuring the continuous and stable operation of the conveyor belt assembly 2.

[0032] Specifically, the bushing 24 has an inner assembly chamber 241, and a bearing 242 is fixedly installed on the cavity wall of the inner assembly chamber 241. The rotating shaft 27 passes through the bearing 242 and is rotatably connected to the bearing 242, which reduces the friction when the rotating shaft 27 rotates. This not only makes the rotating shaft 27 rotate more smoothly and reduces energy loss, but also extends the service life of components such as the rotating shaft 27 and bushing 24, ensures the smooth operation of the conveyor belt 273, and improves the reliability of the conveyor belt assembly 2.

[0033] like Figure 3 As shown, a rectangular slot 272 is provided in the end body of the shaft 27 connected to the servo motor 28. A rectangular rod 281 is fixedly installed at the end of the output shaft of the servo motor 28. The rectangular rod 281 is located in the rectangular slot 272 and is inserted into the rectangular slot 272. The size of the rectangular rod 281 is adapted to the size of the rectangular slot 272, realizing stable power transmission between the servo motor 28 and the shaft 27. This structure is easy to install and disassemble. When it is necessary to repair the servo motor 28 or the shaft 27, the two can be quickly separated, while ensuring stable power transmission during operation and avoiding problems such as slippage and disengagement.

[0034] like Figure 2 As shown, two symmetrical crossbeams 25 are fixedly installed between the left and right U-shaped frames 20. A side plate 26 is fixedly installed on one of the U-shaped frames 20, and the servo motor 28 is fixedly installed on the side plate 26, which enhances the overall structural strength and stability of the conveyor belt assembly 2. The crossbeams 25 make the connection between the two U-shaped frames 20 more secure, and the side plate 26 provides a stable mounting position for the servo motor 28, preventing the components from loosening or shifting due to vibration and other factors during operation, thus ensuring the reliable operation of the conveyor belt assembly 2.

[0035] like Figure 2 As shown, a fixed base 22 is fixedly installed at the bottom of the column 21. The fixed base 22 is fixedly installed on the external base. The fixed base 22 increases the contact area with the base, improves the stability of the equipment, and avoids the material conveying and palletizing machine picking and placing operations affected by shaking during the operation of the conveyor belt 273, thus ensuring the safe operation of the equipment.

[0036] like Figure 2 As shown, the bottom of the fixed base 22 is provided with a bottom pad 23. The bottom pad 23 is fixedly installed on the external base. When the bottom height of the installation site is insufficient, the bottom pad 23 of the corresponding thickness can be selected for support and lifting according to actual needs to ensure that the conveyor belt 273 is at a suitable height and better cooperates with the palletizer body 1, thereby improving the flexibility and applicability of equipment installation.

[0037] When using the conveyor belt storage and retrieval structure of the material box of this utility model, first, according to the installation site conditions, select a bottom pad 23 of appropriate thickness, and then firmly install the fixed base 22, the bottom pad 23 together with the column 21 on the external base to ensure the stability of the conveyor belt assembly 2. Then, fix the servo motor 28 on the side plate 26, and connect the servo motor 28 to the rotating shaft 27 by inserting the rectangular rod 281 into the rectangular groove 272 at the end of the rotating shaft 27.

[0038] After installation, connect the power supply to the servo motor 28 and start the equipment. The servo motor 28 drives the rotating shaft 27 to rotate, which in turn drives the belt roller 271 to rotate, thereby causing the conveyor belt 273 to run. Place the material box at the starting end of the conveyor belt 273, and the material box will be conveyed to the palletizing area under the drive of the conveyor belt 273;

[0039] When the material box arrives at the designated position next to the palletizer body 1, the palletizer body 1 directly performs the material picking operation and transports the material box to the storage or operation target position, or transports the material box on the shelf to the conveyor belt 273 for outward conveying, thus realizing the material picking operation. If the bushing 24 malfunctions during operation, the fastening screws between the fixing ring 243 and the U-shaped frame 20 can be removed, and the bushing 24 can be taken out for repair or replacement to ensure the continuous and stable operation of the equipment.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
