Description

Technical Field

[0001] The present invention relates to the technical field of cargo transportation, and in particular to a transportation device for cargo loading and unloading. Background Art

[0002] A conveyor for cargo handling is a device specifically used for handling and transporting cargo. It is usually composed of a motor, drive, belt, roller or other rolling elements. It can transfer cargo from the ground or storage area to a conveyor belt or a transport vehicle, or transfer cargo from a transport vehicle to the ground or other storage area. The device usually has adjustable parameters such as length, speed and acceleration to accommodate different types of cargo and different loading and unloading environments. In addition, in order to ensure the safety and stability of the cargo during transportation, the conveyor for cargo handling is usually equipped with safety protection measures, such as overload limits, emergency stop buttons, etc.

[0003] When using conveyor belts for loading and unloading goods, if the speed of workers when loading and unloading goods does not match, there will be safety hazards. When the goods fall, the workers may be hit or crushed, causing personal injury. It will also cause losses to production. The falling of goods will cause production interruptions, affecting normal production and delivery time and increasing additional costs. The falling of goods may require additional time and resources for cleaning and repair, adding additional costs to the company. It will also reduce the life of the equipment. Frequent falling of goods may cause additional pressure and wear on the conveyor belt or other equipment, shortening its service life.

[0004] In the existing cargo loading and unloading conveying device, the loading personnel usually stand at one end of the conveying device and directly carry the cargo to the horizontal conveyor belt, and the unloading personnel at the other end of the conveying device unload the cargo on the conveyor belt. When unloading, the loading speed and unloading speed are often inconsistent, that is, the unloading personnel often need to stack the cargo when unloading, so that the time required for unloading is longer than the time for loading. This will cause the cargo on the conveyor belt to fall directly from the conveyor belt before being unloaded, which is not conducive to unloading and will cause damage to the cargo. In addition, during the unloading process, the cargo is often unloaded in a horizontal state, which is not convenient for the unloading personnel to grab, reducing the efficiency of unloading. Summary of the invention

[0005] In view of the problems in the prior art that the speeds of loading and unloading goods are inconsistent, which causes the goods to fall directly from the conveyor belt and is inconvenient to unload, a conveying device for loading and unloading goods is proposed.

[0006] Its purpose is: when the goods reach one end of the conveyor belt, they can temporarily enter the guide plate to wait, increasing the buffer time, which can not only avoid the damage of the goods caused by direct falling, but also facilitate the unloading of the goods by the unloaders.

[0007] The technical solution of the present invention is a conveying device for loading and unloading goods, comprising a conveying frame, a motor arranged on the conveying frame, and a conveyor belt arranged on the conveying frame, and also comprising an auxiliary mechanism arranged at one end of the conveying frame; The auxiliary mechanism includes a supporting component arranged on the conveying frame, and a blocking component arranged on one side of the supporting component; The supporting component is used to guide and support the goods transported to the unloading end, and the blocking component is used to block the goods when the supporting component is deflected to prevent them from falling; The support component includes a support assembly arranged on the top of the conveyor belt, and two limit assemblies arranged in the support assembly; the support assembly is used to support and guide the goods, and the limit assemblies are used to provide support force to the support assembly after the support assembly is deflected toward the unloading personnel; The support assembly includes support plates symmetrically arranged on both sides of the conveying frame, a guide plate arranged between the two support plates, a plurality of sliding rollers arranged on one side of the guide plate, a rotating rod arranged on one side of the bottom of the support plate, the rotating rod is rotatably arranged inside the conveying frame, and a torsion spring is arranged between the rotating rod and the conveying frame.

[0008] Furthermore, the support plate is fan-shaped, and one side of the guide plate is inclined toward the conveying frame.

[0009] Furthermore, deflection blocks are symmetrically arranged on both sides of the bottom of the guide plate. The deflection blocks are arc-shaped, and the bottoms thereof abut against the top of the conveying frame.

[0010] Furthermore, the limiting assembly includes a limiting rod arranged on the side of the support plate close to the conveying frame, an arc-shaped limiting groove opened on the conveying frame, and a limiting point a and a limiting point b arranged at both ends of the limiting groove, and the limiting rod is rotatably connected in the limiting groove.

[0011] Furthermore, the blocking component includes a blocking plate arranged on one side of the guide plate, a lifting plate arranged in the middle of the blocking plate, and a plurality of blocking components evenly distributed between the guide plate and the lifting plate; The blocking assembly is used to rise up to block the cargo when the cargo drives the guide plate to deflect; The blocking assembly includes a sliding groove opened on one side of the bottom of the lifting plate, an extrusion groove opened at the bottom of the sliding groove, a sliding rod arranged in the sliding groove, extrusion rods symmetrically arranged on both sides of the sliding rod, a movable groove opened in the guide plate and connected to the inner cavity of the blocking plate, a spring arranged in the movable groove, one end of the sliding rod is fixedly connected to the spring, a movable hole opened at the top of the movable groove, and a pushing plate arranged in the movable hole, and the bottom of the pushing plate is fixedly connected to the top of the sliding rod.

[0012] Furthermore, the middle portion of the blocking plate is through-shaped, and the top portion thereof is flush with the top portion of the lifting plate.

[0013] Furthermore, the extrusion groove and the sliding groove are both inclined, and one end of the movable rod is pressed against the sliding groove.

[0014] Furthermore, the push plates are evenly dispersed in alternating patterns with different heights.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When conveying goods, when the goods are transported from one end of the conveyor belt to the other unloading end, the goods enter the supporting components under the conveying action of the conveyor belt. When the goods are completely entered into the supporting components, the supporting components are tilted toward the unloading personnel under the action of gravity, so that the goods can be temporarily stored on the supporting components and can be tilted toward the unloading personnel, which is convenient for the unloading personnel to unload and can avoid the unloading personnel from falling due to not having enough time to unload, thereby improving the convenience of unloading.

[0016] 2. It can also prevent the goods from falling directly from the conveyor belt when there is no time to unload them. It not only improves the safety during the unloading process, but also avoids the damage of the goods after they fall directly, provides buffer space for the unloading personnel, and avoids the falling of large quantities of goods when the goods are transported in a concentrated manner.

[0017] 3. The alternating setting of lifting plates of different heights can meet the squeezing and pushing needs of goods of different heights and shapes, improve adaptability, and avoid the situation where goods of different shapes and heights cannot squeeze the pushing plate when sliding down, thereby avoiding the possible direct sliding of goods from the blocking plate and injuring the staff, thereby improving the safety during the unloading process.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] Example 1, reference Figure 1-Figure 8 , which is the first embodiment of the present invention, provides a conveying device for loading and unloading goods, including a conveying frame 1, a motor 11 installed on the conveying frame 1, and a conveyor belt 12 installed on the conveying frame 1, and also includes an auxiliary mechanism installed at one end of the conveying frame 1; the auxiliary mechanism includes a supporting component installed on the conveying frame 1, and a blocking component installed on one side of the supporting component; the supporting component is used to guide and support the goods transported to the unloading end, and the blocking component is used to block the goods when the supporting component is deflected to prevent it from falling; the supporting component includes a supporting assembly 2 installed on the top of the conveyor belt, and a supporting assembly installed on the supporting assembly 2; the support assembly 2 is used to support and guide the goods, and the limit assembly 3 is used to provide supporting force to the support assembly 2 after the support assembly 2 is deflected toward the unloading personnel; the support assembly 2 includes support plates 21 symmetrically installed on both sides of the conveying frame 1, a guide plate 22 fixedly connected between the two support plates 21, a plurality of sliding rollers 23 rotatably connected to one side of the guide plate 22, a rotating rod 24 fixedly connected to one side of the bottom of the support plate 21, the rotating rod 24 is rotatably installed inside the conveying frame 1, and a torsion spring abutting between the rotating rod 24 and the conveying frame 1 (the torsion spring is not drawn in the figure).

[0022] Specifically, when conveying goods, when the goods are transported from one end of the conveyor belt 12 to the other unloading end, the goods enter the supporting component under the conveying action of the conveyor belt 12. When the goods are completely entered on the supporting component, the supporting component is tilted toward the unloading personnel under the action of gravity, so that the goods can be temporarily stored on the supporting component and can be tilted toward the unloading personnel, which is convenient for the unloading personnel to unload and can avoid the unloading personnel not having enough time to unload the goods, causing the goods to fall, thereby improving the convenience of unloading and avoiding the situation where the goods are not able to be unloaded in time, causing the goods to fall directly from the conveyor belt 12, thereby improving the safety of the unloading process and avoiding damage to the goods after they fall directly; when the goods enter the guide plate 2 2, the support plates 21 on both sides are used to support and limit the movement of the goods on the guide plate 22 to prevent the goods from falling from the two sides of the guide plate 22. The setting of the sliding rollers 23 can be used to guide the transportation of the goods and reduce the resistance of the goods sliding on the guide plate 22. When the goods completely enter the guide plate 22, it will cause the guide plate 22 to deflect to one side. The guide plate 22 is located at the end of the unloading and is arranged longer to ensure that the guide plate 22 can tilt to one side after the goods are completely loaded, so that the guide plate 22 can be tilted to one side, which can form an inclined angle that is convenient for unloading, and it is convenient for the unloading personnel to grab the goods, thereby improving the efficiency of unloading. Among them, the torsion spring is used to reset the guide plate 22 after unloading, which is convenient for the subsequent unloading of goods.

[0023] Reference Figure 2-Figure 3 The support plate 21 is fan-shaped, and one side of the guide plate 22 is inclined toward the conveying frame 1.

[0024] Specifically, the fan-shaped support plate 21 can limit the position of the goods during their movement to prevent the goods from falling from both sides, and the inclined design of one side of the guide plate 22 facilitates the entry of the goods.

[0025] Reference Figure 4 and Figure 7 Deflection blocks 25 are symmetrically fixedly connected to both sides of the bottom of the guide plate 22 . The deflection blocks 25 are arc-shaped, and their bottoms abut against the top of the conveying frame 1 .

[0026] Specifically, when the guide plate 22 deflects under the gravity of the goods, the deflection block 25 rotates on the conveyor frame 1 and is used to provide support force for the guide plate 22, improve the support strength, avoid crushing the rotating rod 24 on one side of the support plate 21, and increase the service life of the device.

[0027] Reference Figure 4 The limiting assembly 3 includes a limiting rod 31 fixedly connected to the side of the support plate 21 close to the conveying frame 1, an arc-shaped limiting groove 32 opened on the conveying frame 1, and a limiting point a 33 and a limiting point b 34 arranged at both ends of the limiting groove 32, and the limiting rod 31 is rotatably connected in the limiting groove 32.

[0028] Specifically, the limiting assembly 3 is used to limit the inclination angle of the guide plate 22 to prevent the guide plate 22 from being too deflected at an angle that is inconvenient to unload the goods. It can not only support the guide plate 22 again after it is tilted, but also limit its inclination angle. When the limiting rod 31 rotates to the limiting point a 33, the guide plate 22 will drive the goods to tilt, which is convenient for the unloading personnel to unload the goods. When the limiting rod 31 is reset and rotated to the limiting point b 34 under the reset action of the torsion spring, at this time, one end of the guide plate 22 is in contact with the top of the conveying frame 1, that is, the reset effect of the guide plate 22 after tilting is achieved.

[0029] Example 2, reference Figure 1-Figure 6 , which is the second embodiment of the present invention, which is different from the first embodiment in that: the blocking component includes a blocking plate 4 fixedly connected to one side of the guide plate 22, a lifting plate 5 slidably connected to the middle of the blocking plate 4, and a plurality of blocking components 6 evenly distributed between the guide plate 22 and the lifting plate 5; the blocking component 6 is used to rise to block the goods when the goods drive the guide plate 22 to deflect; the blocking component 6 includes a sliding groove 61 opened on one side of the bottom of the lifting plate 5, an extrusion groove 62 opened at the bottom of the sliding groove 61, a sliding rod 63 slidably connected in the sliding groove 61, an extrusion rod 64 symmetrically fixedly connected to both sides of the sliding rod 63, a moving groove 65 opened in the guide plate 22 and connected to the inner cavity of the blocking plate 4, a spring 66 fixedly connected in the moving groove 65, and one end of the sliding rod 63 is fixedly connected to the spring 66, a movable hole 67 opened at the top of the movable groove 65, and a push plate 68 slidably connected in the movable hole 67, and the bottom of the push plate 68 is fixedly connected to the top of the sliding rod 63.

[0030] Specifically, when the goods are driven onto the guide plate 22, as the goods continue to enter, the component force deflecting to one side becomes larger and larger, causing the guide plate 22 to tilt after passing the balance point. At this time, the guide plate 22 tilts, thereby accelerating the downward movement of the goods on the guide plate 22, causing the goods to squeeze the push plate 68 during the sliding process. The push plate 68 drives the sliding rod 63 to slide in the sliding groove 61 and squeeze the sliding groove 61, so that the lifting plate 5 is squeezed and raised, and the length of the blocking plate 4 is increased to meet the blocking needs of goods of different sizes and to prevent the goods from sliding directly out of one side of the blocking plate 4 under the action of inertia. When the goods are taken out, the sliding rod 63 will be reset under the reset action of the spring 66. The squeezing rods 64 on both sides can be set to prevent the lifting plate 5 from falling and drive the lifting plate 5 to reset and move downward again, thereby improving the storage capacity of the device.

[0031] Reference Figure 2 and Figure 6 The middle part of the blocking plate 4 is through-shaped, and its top is flush with the top of the lifting plate 5.

[0032] Specifically, the lifting plate 5 can be retracted to avoid protrusion of the lifting plate 5, thereby improving safety during use and avoiding collisions of unloading personnel.

[0033] Reference Figure 6 The extrusion groove 62 and the sliding groove 61 are both inclined, and one end of the movable rod is pressed against the sliding groove 61.

[0034] Specifically, it is convenient to squeeze and lift the lifting plate 5 so that the lifting plate 5 can be stored. The remaining structure is the same as that of the first embodiment.

[0035] Example 3, reference Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that the push plates 68 are evenly dispersed in alternating patterns with different heights.

[0036] Specifically, it can meet the needs of squeezing and pushing goods of different heights and shapes, improve adaptability, and avoid the situation where goods of different shapes and heights cannot squeeze the pushing plate 68 when sliding down, thereby preventing the goods from directly sliding off the blocking plate 4 and injuring the staff, thereby improving the safety during the unloading process. The rest of the structure is the same as that of Example 2.

[0037] In summary, the working principle of the present invention is as follows: when conveying goods, when the goods are transported from one end of the conveyor belt 12 to the other unloading end, the goods enter the supporting component under the conveying action of the conveyor belt 12. When the goods completely enter the supporting component, the supporting component is tilted toward the unloading personnel under the action of gravity, so that the goods can be temporarily stored on the supporting component and can be tilted toward the unloading personnel, which is convenient for the unloading personnel to unload and can avoid the unloading personnel not having enough time to unload the goods, causing the goods to fall, thereby improving the convenience of unloading and avoiding the situation where the goods are not able to be unloaded in time and cause the goods to fall directly from the conveyor belt 12, thereby improving the safety of the unloading process and Avoid damage to the goods after they fall directly; when the goods enter the guide plate 22, the support plates 21 on both sides are used to support and limit the movement of the goods on the guide plate 22 to prevent the goods from falling from both sides of the guide plate 22. The setting of the sliding roller 23 can be used to guide the transportation of the goods and reduce the resistance of the goods sliding on the guide plate 22. When the goods completely enter the guide plate 22, it will cause the guide plate 22 to deflect to one side. The guide plate 22 is located at the unloading end and is set longer to ensure that after the goods are completely loaded, the guide plate 22 can tilt to one side, forming an inclined angle that is convenient for unloading, making it convenient for unloading personnel to grab the goods and improving the unloading efficiency.
