[0001] The present invention relates to the technical field of train loaders, and in particular to an automatic train loaders. Background Art

[0002] In the transportation of cement or other materials by train, most of the domestic methods currently adopt the method of loading by conveyor: workers unload the bags from pallets or push carts, put them into the conveyor and transport them to the train carriages, and then multiple workers need to be deployed in the carriages at the other end of the conveyor to carry out the products transported by the conveyor one by one and transport them to the carriages for stacking. This form of manual loading is labor-intensive, the process consumes manpower and material resources, and the efficiency of bag stacking is low. Therefore, in order to improve the loading efficiency of trains and reduce labor costs at the same time, it has become a more realistic problem at present. Summary of the invention

DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] In this embodiment, refer to Figure 1-19 , an automatic train loading machine, comprising a machine body 1, the machine body 1 is composed of a mobile steering mechanism 2, a displacement frame assembly 3, a hydraulic lifting platform 4, a discharge mechanism 5, a shaping mechanism 6 and a stacking feeding mechanism 7, wherein:

[0045] The moving steering mechanism 2 is arranged at the bottom and is used to drive the vehicle body 1 to move and steer.

[0046] The mobile steering mechanism 2 includes a mounting shell 2-101 and a side plate 2-102. The mobile tracks 2-104 are respectively arranged on both sides of the mobile steering mechanism 2. The side plates 2-102 are symmetrically arranged on both sides of the mounting shell 2-101. The outer side surfaces of the side plates 2-102 are respectively used to install the mobile tracks 2-104. The inner side surfaces of the side plates 2-102 are respectively installed with track motors 2-105 for driving the mobile tracks 2-104. The two track motors 2-105 are synchronous motors that can control the synchronous transmission of the mobile tracks 2-104, thereby realizing the forward and backward movement of the vehicle body 1.

[0047] The inner top wall of the mounting shell 2-101 is rotatably mounted with a slewing bearing 2-106, the bottom of the slewing bearing 2-106 is provided with a coaxially rotating mounting base plate 2-103, the top surface of the mounting shell 2-101 is provided with a geared power motor mounting hole 2-108, a geared motor is mounted on the mounting shell 2-101, and a geared shaft provided at the output end of the geared motor extends from the geared power motor mounting hole 2-108 into the mounting shell 2-101 and maintains meshing transmission with the slewing bearing 2-106. The slewing bearing 2-106 can be rotated by the drive of the geared power motor.

[0048] The bottom of the mounting base plate 2-103 is provided with a plurality of hydraulic support legs 2-107. Here, the interior of the mounting shell 2-101 is provided with a hydraulic control switch for lifting and lowering the hydraulic support legs 2-107. Meanwhile, the bottom of the hydraulic support legs 2-107 is provided with a universal wheel for steering.

[0049] When the vehicle body 1 needs to turn, the hydraulic support legs 2-107 are extended downward to lift the entire vehicle body 1 upward, and the moving tracks 2-104 on both sides are suspended in the air. Then the slewing bearing 2-106 is controlled to rotate, so that the mounting base 2-103 can rotate synchronously with the rotation of the slewing bearing 2-106, and finally the turning of the entire vehicle body 1 is realized. When the rotation direction is adjusted, the hydraulic support legs 2-107 are withdrawn so that the moving tracks 2-104 on both sides touch the ground. Subsequently, the moving tracks 2-104 can be used to control the machine to move forward and backward. The entire vehicle body 1 can move forward and backward and turn. When stacking bags, the stacking position can be accurately adjusted, the bag loading efficiency is improved, and the labor intensity is reduced.

[0050] The displacement frame assembly 3 and the hydraulic lifting platform 4 are both arranged on the top of the mobile steering mechanism 2, and the hydraulic lifting platform 4 is arranged on the inner side of the displacement frame assembly 3. The displacement frame assembly 3 is composed of a horizontal support frame 301, a vertical gantry frame 302, a slide motor 303 and a slide plate 304. The slide plate 304 is slidably mounted on the support arms on both sides of the support frame 301. The slide motor 303 drives the slide plate 304 to slide back and forth along the length direction of the support frame 301. The tail of the slide plate 304 is fixedly connected to the gantry frame 302, and the inner plate surfaces of the slide plates 304 on both sides are also provided with electrical cabinets 8.

[0051] The discharge mechanism 5 and the shaping mechanism 6 are both arranged on the hydraulic lifting platform 4, and the shaping mechanism 6 is arranged in the front half of the hydraulic lifting platform 4, and the discharge mechanism 5 is arranged in the rear half of the hydraulic lifting platform 4. The shaping mechanism 6 is used to receive bags and correct the deflected position of bags, and the discharge mechanism 5 is used to arrange the bags transmitted from the shaping mechanism 6.

[0052] A hydraulic motor 401 is provided at the bottom of the hydraulic lifting platform 4 .

[0053] The shaping mechanism 6 includes two parallel side fixing frames 601, which are mounted on the hydraulic lifting platform 4 through fasteners. When the height of the hydraulic lifting platform 4 is changed, the position of the shaping mechanism 6 is also adjusted synchronously. This design is used to adjust and receive bags at different heights.

[0054] The design of the shaping mechanism 6 is specifically described as shown in the attached Fig.12 As shown, a receiving belt 604 is provided on the front side of the shaping mechanism 6, and a roller assembly is provided on the rear side. A power motor for controlling the start of the receiving belt 604 is provided on the side fixing frame 601. The receiving belt 604 can deliver bags transmitted from the outside into the vehicle body 1 in an orderly manner.

[0055] The roller assembly includes a plurality of square conveying rollers 605 and circular conveying rollers 606, which are arranged in sequence, and the two ends of the square conveying rollers 605 and circular conveying rollers 606 are rotatably mounted between the two side fixing frames 601. Fig.12 As shown, the square conveyor roller 605 is arranged at the front and adjacent to the receiving belt 604, while the circular conveyor roller 606 is arranged at the rear. The receiving belt 604, the square conveyor roller 605 and the circular conveyor roller 606 are on the same horizontal plane to facilitate the bag to slide forward.

[0056] Here, shaping plates 602 are respectively provided at the two edges of the rear side of the shaping mechanism 6, and the entrance ends of the shaping plates 602 are respectively provided with outer flanges 603. The design of the outer flanges 603 facilitates the bag to slide smoothly onto the roller assembly, and the shaping plates 602 are aligned with the installation positions of the roller assembly, and the shaping plates 602 on both sides are narrowed in an eight-shaped shape from front to back.

[0057] The bag is slid to the entrance of the square conveyor roller 605 via the receiving belt 604. Once the position of the bag is deviated, the bag position can be shaped and corrected by using the outer flanges 603 on both sides. The outer flanges 603 adjust the conveying direction of the bag. The square conveyor roller 605 can vibrate, so that the bag conveyed above can be vibrated and leveled. Because the bottom of the bag needs to be flat when it is stacked, the square conveyor roller 605 can be used to level the bag. Generally, the bag is a square bag. The bag slides from the entrance of the square conveyor roller 605 to the exit of the circular conveyor roller 606. After shaping, the oblique bag can be adjusted and then conveyed to the vehicle body 1.

[0058] It should be noted that the shaping plate 602 is slidably mounted on the side fixing frame 601, and a sliding column is provided on the outer plate surface of the shaping plate 602, and the sliding column extends downward, and a guide sleeve for the sliding column to be vertically inserted is provided on the side fixing frame 601, and the guide sleeve is radially screwed into the plum-shaped hand screw from the outside to the inside, and the sliding column is fixed by the plum-shaped hand screw. The plum-shaped hand screw is used to adjust the height of the shaping plate 602. By adjusting the height of the shaping plate 602, it can be used to calibrate bags of different sizes, and its scope of use can be expanded.

[0059] The discharge mechanism 5 is composed of an outer mounting frame 501 and an inner mounting frame 504 , wherein the outer mounting frame 501 is provided with sequentially arranged electric conveying rollers 502 , and the inner mounting frame 504 is provided with sequentially arranged longitudinal conveying belts 503 .

[0060] When the height of the hydraulic lifting platform 4 is changed, the position of the discharge mechanism 5 is also adjusted synchronously. Such a design can transport the bags backward at a suitable height.

[0061] Each longitudinal conveyor belt 503 is aligned with the spacing between adjacent electric conveyor rollers 502 . The longitudinal conveyor belt 503 and the electric conveyor roller 502 do not contact each other. Each individual longitudinal conveyor belt 503 is located between two adjacent electric conveyor rollers 502 .

[0062] The longitudinal conveyor belt 503 is used to convey the received bags from front to back, while the motorized conveyor roller 302 is used to convey the bags falling on the discharge mechanism 5 to the left or to the right.

[0063] As attached Figure 8 As shown, guide seats 505 are respectively provided at the lower half of the inner walls on both sides in the width direction of the outer mounting frame 501, a bottom frame 511 is provided at the bottom of the inner mounting frame 504, and sliding blocks 506 are respectively provided on both end surfaces of the bottom frame 511 to slide with the guide seats 505. The inner mounting frame 504 can be lifted and slid vertically along the inner side of the outer mounting frame 501, and the longitudinal conveying belt 503 is higher or lower than the plane where the electric conveying roller 502 is located.

[0064] When the longitudinal conveyor belt 503 is higher than the plane where the electric conveyor roller 502 is located, the conveying process is controlled by the longitudinal conveyor belt 503, and can be used to convey the bags falling on the discharge mechanism 5 to the left or to the right.

[0065] When the longitudinal conveying belt 503 is lower than the plane where the electric conveying roller 502 is located, the conveying process is controlled by the electric conveying roller 502, and can be used to convey the received bags from front to back.

[0066] Regarding the height adjustment method of the inner mounting frame 504, the following is a specific description:

[0067] A transmission shaft 507 is rotatably mounted inside the bottom frame 511 along the length direction, and the two ends of the transmission shaft 507 extend from the two sides of the bottom frame 511 and rotatably mount eccentric wheels 510 at their respective ends. Here, a gear box 508 is also disposed at the bottom of the inner mounting frame 504, and a transmission gear disposed at the output end of the gear box 508 is meshed with a linkage gear sleeved on the shaft of the transmission shaft 507. The eccentric wheels 510 on both sides are driven by the gear box 508 to rotate synchronously.

[0068] The inner walls on both sides of the width direction of the outer mounting frame 501 are respectively provided with fixed matching pieces 509, and a waist-shaped notch is opened in the center of the fixed matching piece 509, and the eccentric wheel 510 is respectively built into the waist-shaped notch of the corresponding fixed matching piece 509. During the eccentric rotation of the eccentric wheel 510, since the position of the fixed matching piece 509 remains unchanged, the entire inner mounting frame 504 will rise and fall and slide along the guide seat 505, and finally be adjusted to the height of the longitudinal conveying belt 503. Through the conversion of the transverse conveyance and longitudinal conveyance of the bags, the bags are arranged in a row on the discharge mechanism 5, and the spacing between adjacent bags is adjusted and controlled, so as to facilitate the subsequent neat output.

[0069] The bottom of the inner mounting frame 504 is provided with a belt adjustment mechanism, as shown in the attached Fig.10 As shown, the belt adjustment mechanism is composed of a bottom frame 511 and an annular frame 504 - 1 , and the bottom frame 511 and the annular frame 504 - 1 are fixedly connected side by side.

[0070] The top surface of the bottom frame 511 is provided with strip brackets 517 which are distributed at equal intervals in sequence, and the strip brackets 517 are arranged along the length direction of the bottom frame 511. Pulleys 517-1 are respectively provided at both ends of the strip bracket 517, and the pulleys 517-1 at both ends of the same strip bracket 517 are synchronously driven by the longitudinal transmission belt 503. The longitudinal transmission belts 503 in a row are controlled to be synchronously or separately driven by the belt adjustment mechanism.

[0071] Here, the tops of the two pulleys 517 - 1 are located above the strip bracket 517 . With such a design, bag transmission can be achieved through the longitudinal transmission belt 503 without being affected by the strip bracket 517 .

[0072] Regarding the annular frame 504-1, a servo motor 512 and a support shaft 513 are disposed in the annular frame 504-1:

[0073] There are multiple groups of servo motors 512, and each output end of the servo motor 512 is provided with a driving wheel 516 that rotates coaxially;

[0074] The number of the supporting shafts 513 is the same as the number of the servo motors 512 , and a rotating wheel 514 and a plurality of driven wheels 515 are sleeved on the shaft of each supporting shaft 513 .

[0075] The number of the rotating wheels 514 is the same as the number of the driving wheels 516 and they are aligned respectively. The rotating wheels 514 and the corresponding driving wheels 516 are synchronously driven by a three-stage belt.

[0076] In this embodiment, the number of the servo motors 512 is set to three groups, and correspondingly, the number of the supporting shafts 513, the driving wheels 516 and the rotating wheels 514 is also three.

[0077] The servo motor 512 starts to control the driving wheel 516 to rotate, and uses the three-stage belt to realize the synchronous rotation of the rotating wheel 514 on the support shaft 513. Then, a plurality of driven wheels 515 installed on the same support shaft 513 rotate synchronously with the support shaft 513.

[0078] The number of driven wheels 515 arranged on the three support shafts 513 is the same as the number of the strip brackets 517 above. Here, the number of driven wheels 515 and the strip brackets 517 is designed to be 3n (n≥2), and the driven wheels 515 and the pulleys 517-1 at both ends of the corresponding strip brackets 517 maintain synchronous transmission through the same longitudinal transmission belt 503.

[0079] When a driven wheel 515 rotates, it will drive the longitudinal conveyor belt 503 connected thereto to transmit synchronously. The same servo motor 512 can be used to control multiple longitudinal conveyor belts 503 to work simultaneously. The three servo motors 512 correspond to the left, middle and right areas of the discharge mechanism 5, respectively. Therefore:

[0080] When conveying bags of the same type, the three servo motors 512 are synchronous motors and can be turned on at the same time to ensure that the longitudinal conveyor belts 503 arranged in a row on the discharge mechanism 5 work together. This can increase the conveying quantity of a single batch of bags.

[0081] When conveying multiple types of bags, the three servo motors 512 are asynchronous motors that can be controlled to turn on separately. Workers can selectively turn on one or more of the motors according to the needs of the bag conveying position to convey different types of bags to designated locations.

[0082] The stacking and feeding mechanism 7 is arranged at the rear of the displacement frame assembly 3 , and the stacking and feeding mechanism 7 slides vertically along the displacement frame assembly 3 . The stacking and feeding mechanism 7 is used to receive the bags conveyed by the discharge mechanism 5 and send the bags outward for stacking.

[0083] The stacking and feeding mechanism 7 includes a guide frame 701 and a stacking platform 702. The gantry frame 302 is connected to the guide frame 701 through a rigid chain elevator and controls its vertical sliding. The guide frame 701 is equipped with a stacking platform 702 that slides laterally. A plurality of conveyor belts 704 arranged in sequence are arranged on the table of the stacking platform 702, and bags to be conveyed are placed on the conveyor belts 704.

[0084] Combined with Figure 5 The structure of the rigid chain elevator is described below. As shown in the figure, the rigid chain elevator includes a servo motor 302-1, an annular winding belt 302-2 and a first rigid chain 302-3. The gantry frame 302 is rotatably installed with a rotating shaft 302-4 near its top wall and bottom wall respectively. The two ends of the upper and lower rotating shafts 302-4 are respectively connected with coaxially rotating sprockets. The outer peripheries of the sprockets aligned up and down on the same side are kept in synchronous transmission through the first rigid chain 302-3.

[0085] The output end of the servo motor 302-1 is provided with a linkage wheel, and another linkage wheel is sleeved on the shaft of the upper rotating shaft 204. The upper and lower linkage wheels are aligned and synchronously driven through the annular winding belt 302-2. The servo motor 302-1 is driven to control the linkage wheel at its output end to rotate, and the upper rotating shaft 302-4 and the sprocket wheels at both ends are controlled to rotate through the transmission of the annular winding belt 302-2. Since the upper and lower sprocket wheels are driven through the first rigid chain 302-3, the first rigid chains 302-3 on the left and right sides will maintain synchronous transmission.

[0086] Here, the servo motor 302-1 can rotate forward and reverse to control the two first rigid chains 302-3 to drive forward or reverse. It should be noted that the outer surfaces of the two arms of the gantry frame 302 are provided with slide grooves that slide vertically, and the guide frame 701 is provided with a slider that matches the slide groove, and the inner surface of the guide frame 701 is fixedly connected to the first rigid chain 302-3.

[0087] The guide frame 701 is fixedly connected to the first rigid chain 302-3. Therefore, the guide frame 701 can be vertically raised and lowered with the forward and reverse transmission of the first rigid chain 302-3, and finally the height of the stacking platform 702 installed in the guide frame 701 can be adjusted. The vertical position adjustment of the stacking platform 702 is the adjustment of the stacking height, and the bags can be stacked at different heights.

[0088] As attached Fig.14 or attached Fig.15As shown, the guide frame 701 is a U-shaped structure, and a guide bar 701-1, a mold rack 701-2 and a second rigid chain 701-3 are arranged in the guide frame 701. Two groups of guide bars 701-1 are arranged along the inner wall surface of the guide frame 701 and remain parallel. The mold rack 701-2 is fixedly installed in the guide frame 701, and the sliding direction of the mold rack 701-2 is parallel to the extension direction of the guide bar 701-1.

A gear 702-3 is arranged at the output end of the rotating motor 702-1. The gear 702-3 and the mold rack 701-2 are meshed and transmitted. The rotation of the gear 702-3 is controlled by the rotating motor 702-1, so that the gear 702-3 can translate along the length direction of the mold rack 701-2 during the rotation process.

[0090] It should be particularly noted that a sliding seat 702-2 that is slidably matched with the guide bar 701-1 is provided on the stacking platform 702. In addition, one end of the second rigid chain 701-3 is fixed to the bottom wall of the guide frame 701, and the other end of the second rigid chain 701-3 is provided with a connecting seat 701-4, the inner surface of the connecting seat 701-4 is connected to the mold rack 701-2, and the outer surface of the connecting seat 701-4 is connected to the stacking platform 702.

[0091] The stacking platform 702 can adjust the stacking height of the bags according to actual conditions, and can also adjust the stacking position of the bags in the horizontal direction, so as to accurately place the bags in the designated positions, ensure that the upper and lower bags are aligned, and make full use of the storage space inside the carriage.

[0092] The stacking table 702 is designed as a rectangular mounting frame 703, and the internal space of the mounting frame 703 is divided into several identical feeding tables. The internal space of the mounting frame 703 is divided into several identical feeding tables. The feeding tables include two fixed brackets 708 arranged on the outer layer and two sliding brackets 709 arranged on the inner layer. A conveyor belt 704 is arranged inside the sliding bracket 709.

[0093] Combined with Fig.16 And attached Fig.17It can be seen that a power roller 705, a driven roller 706 and a matching roller 707 are arranged between the sliding brackets 9, the power roller 705 and the driven roller 706 are respectively arranged at both ends of the sliding bracket 709, and the matching roller 707 is arranged between the power roller 705 and the driven roller 706 and multiple groups are arranged. The conveyor belt 704 is an annular closed belt body and is matched and wound around the outside of the power roller 705, the driven roller 706 and the matching roller 707 to realize the conveyance of bags.

[0094] A conveyor belt 704 is provided in each feeding platform, so the multiple groups of conveyor belts 704 provided in this embodiment can realize the conveyance of multiple bags at the same time, thereby improving the conveyance efficiency.

[0095] Combined with Fig.18 And attached Fig.19 The two ends of the fixed brackets 708 on both sides are respectively rotatably mounted with secondary pulleys, and the secondary pulleys at both ends of the same fixed bracket 708 are connected by a secondary belt 713. The fixed brackets 708 on both sides are connected to the secondary pulleys at the outer ends by a fixed shaft, and a primary pulley is sleeved on the fixed shaft. An adjusting motor 710 is arranged at the bottom of the feeding table, and a tertiary pulley is arranged at the output end of the adjusting motor 710, and the tertiary pulley is connected to the primary pulley by a primary belt 714.

[0096] The adjusting motor 710 is started, and the tertiary pulley is controlled to rotate synchronously with the primary pulley through the primary belt 714, and then the secondary pulleys at both ends of the fixed shaft are driven to rotate synchronously through the primary pulley. Since the secondary pulleys on the two sliding brackets 709 are connected by the secondary belt 713, the purpose of synchronous circular transmission of the secondary belts 713 on both sides can be finally achieved.

[0098] It is worth mentioning that, in combination with the Fig.18 It can be seen that the connecting plate 712 is an L-shaped structural plate, one side of the connecting plate 712 is connected to the inner wall of the sliding bracket 709 , and the other side of the connecting plate 712 is connected to the rigid chain belt 711 and the secondary belt 713 .

[0099] When the secondary belts 713 on both sides start to convey synchronously, they will drive the rigid chain belt 711 and the sliding bracket 709 to slide outward in a straight line along the length direction of the fixed bracket 708. When stacking and feeding, the feeding table can slide outward, so that the bags on the conveyor belt 704 can be automatically output outward, and manual participation in stacking is no longer required, the work intensity is reduced, and the efficiency of bag stacking is improved.

[0100] Specific working process: The bags are conveyed into the carriage via the external conveyor belt, and the loader moves to the end of the conveyor belt. The entrance of the shaping mechanism 6 is positioned by moving the steering mechanism 2, the slide motor 303 of the mounting frame assembly 3, and the hydraulic lifting platform 4, ensuring that the entrance is aligned with the end of the conveyor belt, and the bags are connected to the loader. The position of the bags is first corrected by the shaping mechanism 6, and then the bags are sent to the discharge mechanism 5 with the correct position, and the bags are arranged in three rows on the discharge mechanism 5. The height of the stacking feeder 7 is adjusted to ensure that the bags on the discharge mechanism 5 just enter the stacking feeder 7, and the conveyor belt 704 of the stacking feeder 7 can slide forward, and finally the three rows of bags are stacked together at the designated position.
