Description

Technical Field

[0001] The utility model relates to the technical field of loading and transporting equipment, in particular to a multi-station loading and conveying device and a loading machine. Background Art

[0002] In freight transportation, many bulk goods are transported in bags. The transportation process is usually completed by transport vehicles. The labor required for loading or unloading bags of goods is the largest, and manual loading has low loading efficiency.

[0003] In the prior art, in order to improve the loading efficiency, a multi-station packaging device is disclosed in the announcement number CN212333081U, including a first transport structure, a sub-packaging structure connected to the first transport structure, a second transport structure and a third transport structure respectively connected to the sub-packaging structure, and a bag grabbing structure arranged between the second transport structure and the third transport structure. The sub-packaging structure includes a rotating structure connected to the first transport structure and used to transfer the material bag to the second transport structure or the third transport structure, and a first transition structure and a second transition structure respectively connected to the second transport structure and the third transport structure; the bottom of the end of the first transport structure is fixedly connected to a first bracket for fixing and installing the first transition structure and the second transition structure. The multi-station packaging device of the utility model solves the shortcomings of low efficiency, high labor intensity, and dust harming the human body during the packaging process of traditional manual packaging, and provides a multi-station packaging device that saves manpower, has a high degree of automation, and has high loading efficiency.

[0004] However, with the current increase in the demand for loading, companies are increasingly pursuing high efficiency in loading. Although the above patent transports materials through the second transport structure and the third transport structure, and then loads the materials through the grabbing structure between the second transport structure and the third transport structure, there is still a problem of low efficiency in the actual loading process. Before loading, the truck driver needs to park the truck between the second transport structure and the third transport structure. Due to the long compartment of the truck, it is difficult for the driver to quickly reverse into the passage between the second transport structure and the third transport structure. The narrow space will take a lot of time to reverse. In order to avoid the truck from colliding with the second transport structure, the second transport structure or the H-shaped steel, the distance and height between the second transport structure and the third transport structure need to be increased to reserve enough driving space for the truck. However, the larger space between the truck and the grabbing structure will cause the travel of the grabbing structure in the horizontal and vertical directions to become longer, thereby reducing the efficiency of the device. To solve this problem, the present application proposes a multi-station loading and conveying device. Utility Model Content

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the utility model clearer, the implementation mode of the utility model will be further described below in conjunction with the accompanying drawings.

[0049] Please refer to Figure 1-Figure 5As shown, an embodiment of the utility model provides a multi-station loading and conveying device 100, including a support platform 1, two groups of conveying components 2 and a driving device 3. The support platform 1 is arranged along the front-to-back direction, and includes two vertical frames 11 arranged in parallel and spaced apart along the left-to-right direction. A passage is formed between the two vertical frames 11 for trucks to dock. It is worth noting here that the support platform 1 can be a frame structure, or a wall structure, a seat structure, etc., which is mainly used to fix parts and enable the conveying components 2 to be located above the railing of the truck compartment. There is no limitation here, and the support platform 1 of the above structure is within the protection scope of this application.

[0050] The two groups of conveying components 2 are respectively movably arranged on the two upright frames 11 along the front-rear direction, and the adjacent side of the two groups of conveying components 2 is arranged in the channel, each of the conveying components 2 includes a horizontal conveying structure 21, an inclined conveying structure 22 and a roller conveying structure 23 which are sequentially connected from back to front, the horizontal height of the horizontal conveying structure 21 is higher than the horizontal height of the roller conveying structure 23, and the inclined conveying structure 22 is extended downward from back to front; the driving device 3 is arranged between the conveying component 2 and the upright frame 11, and is used to drive the conveying component 2 to move along the front-rear direction.

[0051] By setting two groups of conveying components 2 to feed materials on both sides of the channel respectively, it is helpful to improve the loading efficiency compared with a single conveying device. In the present application, by raising the horizontal conveying structure 21, setting the horizontal height of the horizontal conveying structure 21 higher than the horizontal height of the roller conveying structure 23, and then using the inclined conveying structure 22 for transition, the horizontal conveying structure 21 and the inclined conveying structure 22 at the rear of the channel are both much higher than the height of the carriage, and the roller conveying structure 23 is located at the height of the lower carriage railing, so that during the material transportation from back to front, the travel of the bag grabbing device 210 in the height direction and the horizontal direction during loading is shorter, which can further improve the loading efficiency; at the same time, because the height of the horizontal conveying structure 21 and the inclined conveying structure 22 are both higher than the height of the carriage, sufficient reversing space is reserved for the truck driver, and it is less difficult for the driver to enter the channel and is not easy to collide with the support platform 1.

[0052] In addition, compared with the prior art in the background technology, the present application uses two separate conveying components 2 to feed materials at the same time, which has high stability and high speed. In the prior art, the materials are first conveyed through the first transport structure and then sub-packaged through the sub-package structure. Each bag of materials needs to be swung and sub-packaged by the sub-package structure. This process will greatly reduce the conveying efficiency, which may easily cause the bag grabbing structure located in the front to be in short supply and reduce the loading efficiency. Moreover, the sub-package structure is prone to wear and failure under high-frequency swing, and it is easy to reach a conveying bottleneck. The stability and efficiency of the conveying structure of the present application are much higher than those of the prior art.

[0053] Here, it is worth noting that the horizontal conveying structure 21 and the inclined conveying structure 22 involved in the present invention are both conveying belt conveyors, and the roller conveying structure 23 is a roller 82 conveyor. The conveying belt conveyor and the roller 82 conveyor are both common conveying structures and are both existing technologies. The specific structure will not be described in detail here.

[0054] Specifically, refer to Figure 1 and Figure 5 As shown, it also includes a plurality of support frames 41, two brackets 5 and two support plates 6. The plurality of support frames 41 are arranged at intervals in the front-to-back direction, and each of the support frames 41 is arranged across the channel above the vertical frame 11, and is used to support the two horizontal conveying structures 21; the two support plates 6 are respectively fixed at the front ends of the two vertical frames 11, and the two support plates 6 extend into the channel, and are respectively used to fix the two roller conveying structures 23; one end of the two brackets 5 is connected to the bracket 5 located at the front, and the other end extends downward to be connected to the support plate 6, and is respectively used to support the two inclined conveying structures 22.

[0055] By setting the support frame 41 across the channel, it is helpful to fix the support horizontal conveying structure 21 installed on the inner side of the channel, so that it is infinitely close to the car body railing in the horizontal direction, and further raised by the height of the support frame 41, so as not to interfere with the truck driver entering the channel, and sufficient parking space is reserved below. Correspondingly, the inclined conveying structure 22 and the roller conveying structure 23 are fixed in sequence by the bracket 5 and the support plate 6. In this structure, only a small section of the roller conveying structure 23 is close to the height of the truck body railing, which will not affect the truck entering. Due to the long length of the truck, the difficulty of docking mainly lies in the large swing amplitude of the car body. The larger the truck, the larger the swing amplitude of the rear of its car body. The present application solves the problem of insufficient swing space for the car body in the prior art or the long loading journey and low efficiency caused by the large reserved space.

[0056] Furthermore, a fixing rod 7 is fixedly connected between the support plate 6 and the support frame 41 located at the front, and between two adjacent support frames 41. The support frame 41 and the support plate 6 are connected into a whole by the fixing rod 7, which further improves the stability of the conveying assembly 2 and facilitates the consistency of its forward and backward movement.

[0057] Specifically, refer to Figure 5-7As shown, the driving device 3 includes a mounting frame 31 , at least two slide rails 32 , a plurality of pulleys 33 , two racks 35 , two gears 36 , a connecting shaft 37 , four sprockets 38 , two chains 39 and a motor 40 . The two ends of the mounting frame 31 are fixed on the top of the two support plates 6 respectively; at least two slide rails 32 extend in the front-to-back direction and are arranged on the top of the two upright frames 11; a plurality of pulleys 33 are arranged at intervals in the front-to-back direction, and the pulleys 33 are rotatably arranged on the bottom of the support plate 6 and the support frame 41 through a rotating shaft 34, and the pulleys 33 are rollingly arranged on the top of the slide rails 32; two racks 35 are arranged at intervals and parallel on the sides of the two slide rails 32; two gears 36 correspond to the two racks 35 one by one, and the gears 36 are rotatably arranged on the support plate 6 through a rotating shaft 34, and the gears 36 are meshed with the racks 35; a connecting shaft 37 extends left and right and is rotatably arranged on the top of the mounting frame 31; two of the sprockets 38 are respectively fixed at the two ends of the connecting shaft 37, and the other two sprockets 38 are respectively fixed on the two rotating shafts 34 connected to the gears 36, where the gears 36, pulleys 33 and sprockets 38 on the support plate 6 are connected to the same rotating shaft 34. The two chains 39 are respectively meshed with the upper and lower sprocket wheels 38 at the two ends of the channel and are wound around the outer sides of the upper and lower sprocket wheels 38 ; the output end of the motor 40 is connected to one end of the connecting shaft 37 .

[0058] The sprockets 38 and chains 39 at both ends are connected by a connecting shaft 37. A motor 40 drives the connecting shaft 37 to rotate, which can simultaneously drive the gears 36 at both ends to rotate on the racks 35, thereby simultaneously driving the pulleys 33 at both ends to roll, which helps to maintain the consistency and stability of the conveying components 2 at both ends during the forward and backward movement.

[0059] In this embodiment, the bottom of each support frame 41 and the support plate 6 is rotatably connected to the rotating shaft 34 through two bearing seats spaced apart on the left and right. Pulleys 33 are respectively fixed at both ends of the rotating shaft 34. Four slide rails 32 are provided in the driving device 3. Every two slide rails 32 are arranged on both sides of the corresponding rack 35. The two pulleys 33 are respectively rollingly connected to the two slide rails 32.

[0060] Two slide rails 32 are respectively arranged on the two side frames 11 , and two pulleys 33 are arranged at the bottom of each support frame 41 and the support plate 6 , which helps to improve the stability of the movement of the conveying component 2 and also helps to improve the stability of the support frame 41 and the support plate 6 .

[0061] Further, refer to Figure 2 and Figure 4As shown, the inclined conveying structure 22 includes a plurality of conveying belts arranged in sequence. The inclined conveying structure 22 can set the speed of each conveying belt separately, so that the speed of the plurality of conveying belts decreases from the back to the front, thereby playing a buffering role, so that the material can reach the roller conveying structure 23 smoothly.

[0062] Furthermore, refer to Figure 3 and Figure 8 As shown, guide structures 8 are provided on both sides of the inclined conveying structure 22, and the guide structure 8 includes guide plates 81 and a plurality of rollers 82.

The plurality of rollers 82 are arranged in sequence along the extension direction of the conveyor belt, and both ends of each roller 82 are rotatably provided at the upper and lower ends of the guide plate 81.

[0063] By providing the guide structure 8 on both sides of the inclined conveying structure 22, it is helpful to guide and straighten the material so that it enters the roller conveying structure 23 in a preset posture, thereby improving the accuracy of the subsequent loading of the bag.

[0064] Furthermore, a plurality of adjustment mechanisms 9 are provided between the guide plate 81 and the conveyor belt, and the plurality of adjustment mechanisms 9 are arranged at intervals along the extension direction of the conveyor belt. The guide plate 81 is adjusted in the height direction, the width direction and the angle between the two guide plates 81 by the adjustment mechanism 9 to adapt to the conveying, guiding and shaping of materials of different specifications.

[0065] Reference Figure 4 and Fig. 9 As shown, each of the adjustment mechanisms 9 includes an adjustment seat 91, a connecting plate 92, a fixing plate 94 and at least two bolts. The adjustment seat 91 is provided with a first adjustment hole 911 and a second adjustment hole 912 at intervals, the first adjustment hole 911 extends horizontally, and the second adjustment hole 912 extends vertically. The adjustment seat 91 is also provided with a first through slot 913 and a second through slot 914 which are respectively connected to the first adjustment hole 911 and the second adjustment hole 912, and the side walls of the first through slot 913 and the second through slot 914 are penetrated by a through hole 915; one side of the connecting plate 92 is used to be fixed on the guide plate 81, and the other side of the connecting plate 92 is provided with a horizontal adjustment shaft 93, and the horizontal adjustment shaft 93 is inserted into the first adjustment hole 911; one side of the fixing plate 94 is used to be fixed above the side wall of the conveyor belt machine, and the other side of the fixing plate 94 is provided with a vertical adjustment shaft 95 which is upwardly protruded, and the vertical adjustment shaft 95 is inserted into the second adjustment hole 912; at least two bolts are inserted into the through hole 915 and are fixed by nuts.

[0066] The width between the two guide plates 81 can be adjusted by the relative movement of the first adjustment hole 911 and the horizontal adjustment shaft 93; the height of the guide plate 81 can be adjusted by the relative movement of the second adjustment hole 912 and the vertical adjustment shaft 95, and the adjustment seat 91 can also use the rotation of the second adjustment hole 912 and the vertical adjustment shaft 95 to adjust the angle between the two guide plates 81. The two guide plates 81 can be adjusted to be parallel to each other, or to be adjusted to a trumpet shape with a gradually decreasing angle from back to front. After being adjusted to the preset state, the first adjustment hole 911 and the horizontal adjustment shaft 93, and the second adjustment hole 912 and the vertical adjustment shaft 95 are locked and fixed by the cooperation of the bolts with the first through slot 913 and the second through slot 914.
