Description

Technical Field

[0001] The present invention relates to the field of automatic loading equipment, in particular to automatic cargo loading equipment. Background Art

[0002] The automatic loading equipment includes a gantry that can be moved between the cargo and the carriage, a rotating gantry structure driven by a rotary drive device on the top of the gantry, and a cargo handling frame installed on the rotating gantry structure that can be raised and lowered and swung.

[0003] For example, the prior application with application number 202123440398.5, entitled "An Automatic Loading Device," has the following cargo loading process: after the cargo handling rack swings down and drives the fork frame to swing down, the gantry moves forward to insert the fork frame of the cargo handling rack into the corresponding cargo pallet, and then the cargo handling rack swings up and rises to lift the cargo. Subsequently, the gantry moves backward while the rotary drive device drives the rotary gantry structure to rotate and drive the cargo to turn horizontally 180° toward the carriage. When the cargo moves to the corresponding position in the carriage, the cargo handling rack descends and swings down, and the gantry moves forward to allow the cargo to separate from the fork frame, thereby effectively lifting and loading and unloading the cargo.

[0004] However, the existing automatic loading equipment has the following defects: 1. The rotary drive device is arranged on the top of the gantry, resulting in low utilization of the vertical space inside the gantry, increasing the overall height of the equipment and occupying a large vertical space, making it difficult to adapt to installation in a smaller height space. In addition, the rotary drive device needs to drive the rotary gantry structure and the cargo handling frame to rotate together, resulting in a large moment of inertia and unstable rotation, causing excessive displacement of the cargo on the fork during rotation, which in turn causes uneven loading; 2. The lower hem of the cargo handling frame needs to be driven by an additional swing drive structure in addition to the lifting drive structure, which increases the drive cost.

[0005] The purpose of this invention is to design an automatic cargo loading device to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0009] A transverse frame is driven to move transversely by a transverse driving mechanism, and a lifting driving mechanism is installed on the transverse frame;

[0010] A mounting frame is provided with a rotary drive mechanism and is located below the transverse frame, wherein both ends of the mounting frame are rotatably connected to a first linkage mechanism and a second linkage mechanism, the first linkage mechanism and the second linkage mechanism extend upward and are respectively driven by the lifting drive mechanism to move up and down;

[0011] The conveying mechanism is located at the bottom of the mounting frame and is driven by the rotating drive mechanism to rotate horizontally. The conveying mechanism is used to insert and remove corresponding goods; the lifting drive mechanism is used to drive the first linkage mechanism and the second linkage mechanism to move in the same direction to drive the mounting frame and the conveying mechanism to move up and down, or drive the first linkage mechanism and the second linkage mechanism to move in opposite directions or one of them to move, so as to drive the mounting frame and the conveying mechanism to swing to an inclined setting.

[0012] Furthermore, the lifting drive mechanism includes a fixed frame installed on the inner side of the transverse frame, and lifting electric cylinders fixed in the fixed frame in the front and rear distributions. The first linkage mechanism and the second linkage mechanism have the same structure and are symmetrically arranged. The first linkage mechanism includes several levels of telescopic frames that are slidably connected and linked to each other from top to bottom. The highest-level telescopic frame is slidably connected to the fixed frame and is respectively connected to the telescopic rods of the corresponding lifting electric cylinders. The lowest-level telescopic frames of the first linkage mechanism and the second linkage mechanism are respectively hinged to the front and rear ends of the mounting frame. The rotation drive mechanism is arranged in the middle of the mounting frame and between the lowest-level telescopic frames on the front and rear sides.

The corresponding telescopic rods are respectively connected to the middle sides of the first-level frame of the first linkage mechanism and the second linkage mechanism, and the left and right lower ends of the third-level frame of the first linkage mechanism and the second linkage mechanism are respectively hinged to the left and right sides of the front and rear top of the mounting frame to form a four-corner connection.

[0014] Furthermore, the first linkage mechanism also includes a primary linkage component and a secondary linkage component, the primary linkage component includes a number of primary sprockets rotatably arranged on the upper part of the primary frame, and a primary chain that is connected to the lower part of the secondary frame at one end after passing through the number of the primary sprockets respectively, and the number of the primary sprockets is higher than the lower end of the fixed frame and the other ends of the number of the primary chains are fixedly connected to the lower end of the fixed frame, and the secondary linkage component includes a number of secondary sprockets rotatably arranged on the upper part of the secondary frame, and a secondary chain that is connected to the lower part of the tertiary frame at one end after passing through the number of the secondary sprockets respectively, and the number of the secondary sprockets is higher than the lower end of the primary frame and the other ends of the number of the secondary chains are fixedly connected to the lower end of the primary frame.

[0015] Furthermore, the conveying mechanism includes a baffle which is vertically arranged and connected to the rotary drive mechanism through a rotating seat at the upper end, a push-pull frame which is slidably connected to the rotating seat back and forth, and a conveying frame which is connected to the push-pull frame and is vertically located on the rear side of the baffle. The rotary drive mechanism is used to drive the rotating seat to rotate, and the baffle is provided with several rows of through holes distributed vertically, and the side of the conveying frame close to the baffle is provided with several rows of inserted rods distributed vertically and whose ends slide through the through holes. The rotating seat is provided with a push-pull drive mechanism for driving the push-pull frame to drive the conveying frame to move horizontally back and forth.

[0016] Furthermore, the push-pull frame includes a sliding frame whose left and right inner sides are slidably connected to the left and right outer sides of the rotating seat, a connecting rod that is detachably arranged on the rear side of the transport frame and vertically connects the left and right bottoms of the sliding frame, and a reinforcing rod connecting the connecting rod and the rear end of the sliding frame. A right-angled triangle structure is formed between the sliding frame, the connecting rod, and the reinforcing rod.

[0017] Furthermore, the other ends of the plurality of insertion rods pass through the transport rack and are connected to a limiting block, and one end of the limiting block is laterally extended and detachably arranged from the transport rack.

[0018] Furthermore, the front and rear sides of the fixed frame are slidably connected to the front and rear sides of the top of the transverse frame, and the top of the transverse frame is provided with an adjustment drive mechanism for driving the fixed frame to move horizontally.

[0019] The beneficial effects of the present invention are:

[0020] 1. The two ends of the mounting frame are connected by rotating the first linkage mechanism and the second linkage mechanism to stably hang the mounting frame under the transverse frame, so as to avoid excessive shaking of the mounting frame when the driving mechanism drives the conveying mechanism to rotate, and reduce the installation position of the rotary driving mechanism, so as to improve the vertical space utilization rate under the transverse frame and reduce the overall height of the equipment, saving vertical space, and the rotary driving mechanism only needs to drive the conveying mechanism to rotate, thereby reducing the moment of inertia, improving the rotation stability, avoiding excessive displacement of the goods on the conveying mechanism during rotation, improving the regularity of the cargo loading, and ensuring the space utilization rate of the carriage; and, by adding the first linkage mechanism and the second linkage mechanism, the lifting driving mechanism can drive the mounting frame and the conveying mechanism to rise and fall smoothly, When the transporting mechanism lifts and transports the goods into the carriage and is about to unload them, or after the transporting mechanism inserts the goods, the mounting frame and the transporting mechanism are driven to swing to an inclined setting, so that the goods are tilted and slid down to be unloaded into the carriage to meet the loading requirements of the goods fitting tightly together, or the goods are tilted and moved inward on the transporting mechanism to improve the stability of the transporting mechanism in lifting and transporting. Therefore, without adding a new driving structure, the multifunctional drive of the lifting drive mechanism is realized by adding the first linkage mechanism and the second linkage mechanism to reduce the driving cost, and the weight of the mounting frame, the rotating drive mechanism and the transporting mechanism is dispersedly transmitted to the lifting drive mechanism through the first linkage mechanism and the second linkage mechanism, so as to avoid the concentration of force on the lifting drive mechanism and improve the driving stability.

[0021] 2. By setting the first linkage mechanism and the second linkage mechanism to slide and sleeve in stages from top to bottom and link and extend and retract in several stages, the connection points of the upper and lower ends of the lifting electric cylinder are shortened from between the fixed frame and the mounting frame to between the fixed frame and the highest-level telescopic frame, thereby ensuring that the first linkage mechanism and the second linkage mechanism drive the mounting frame up and down, the required length of the telescopic rod of the lifting electric cylinder is greatly shortened, the overall length of the lifting electric cylinder is shortened, and the vertical structural compactness of the first linkage mechanism and the second linkage mechanism is improved, and the overall height of the equipment is further reduced; at the same time, the rotary drive mechanism is arranged in the middle of the mounting frame, which can improve the force balance between the first linkage mechanism and the second linkage mechanism, further improve the stability of the mounting frame suspended under the transverse frame, and the stability of the mounting frame driven to rise or fall or tilt by the first linkage mechanism and the second linkage mechanism.

[0022] 3. By hingedly connecting the four corners of the mounting frame by two or three-stage frames, the connection strength between the two is improved, thereby improving the stability of the mounting frame suspended in the transverse frame, further avoiding excessive shaking of the mounting frame when the driving mechanism drives the conveying mechanism to rotate, and performing multi-stage overlapping guidance through the guide sliders and guide rails between the fixed frame, the first-stage frame, the second-stage frame, and the third-stage frame, to achieve four-side vertical stable high-precision guidance, ensuring the stability of the first linkage mechanism and the second linkage mechanism driving the mounting frame and the conveying mechanism to move up and down and swing to an inclined setting, especially avoiding the relative skew between the first linkage mechanism and the second linkage mechanism when the mounting frame and the conveying mechanism swing to an inclined setting, resulting in structural damage, thereby improving the overall stability and reliability of the equipment.

[0023] 4. When the lifting electric cylinder drives the first-level frame and several first-level sprockets to rise, the second-level frame and several second-level sprockets are lifted by several first-level chains and gradually retracted into the first-level frame. At the same time, the second-level frame lifts the third-level frame through several second-level chains and gradually retracts into the second-level frame. When the lifting electric cylinder drives the first-level frame and several first-level sprockets to descend, the second-level frame and several second-level sprockets are lowered by several first-level chains and gradually extended downward. At the same time, the second-level frame lowers the third-level frame through several second-level chains and gradually extends downward, thereby realizing the linkage extension and retraction between the first-level frame, the second-level frame and the third-level frame. On this basis, by installing the first-level sprocket and the second-level sprocket at the high position of the first-level frame and the second-level frame, and connecting one end of the chain and the second-level chain to the low position of the second-level frame and the third-level frame, the linkage extension and retraction stroke of the second-level frame and the third-level frame is increased, and a larger range of lifting stroke is achieved under the premise that the length of the second-level frame and the third-level frame is the same.

[0024] 5. After several layers of cotton rolls are lifted into the carriage by inserting several rows of rods into the multi-layer comb-tooth shelves, the mounting frame and the transport mechanism are driven to tilt until the ends of the several rods swing down, and then the push-pull frame is driven to drive the transport frame to pull away from the baffle to separate the several layers of cotton rolls, so that the several layers of cotton rolls are pushed by the baffle and fall into the carriage, thereby completing the loading of several layers of cotton rolls, and the pushing and blocking effect of the baffle realizes the stable stacking and loading of several layers of cotton rolls, which greatly saves labor costs and loading speed.

[0033] Reference Figure 1-8 As shown, an automatic cargo loading device includes:

[0034] The transverse frame 1 is driven to move transversely by a transverse drive mechanism 2. A lifting drive mechanism 3 is installed on the transverse frame 1. Specifically, the transverse drive mechanism 2 includes two parallel ground rails 21 and a traveling frame 22 driven by a motor to slide transversely on the ground rails 21. The left and right ends of the transverse frame 1 are mounted on the traveling frame 22 through pillars to form a gantry. The transverse drive mechanism 2 drives the transverse frame 1 to move transversely between the vehicle and the cargo. The specific structure of the transverse drive mechanism 2 is prior art and is not the main invention of this application, and will not be described in detail here.

[0035] A mounting frame 4 is provided with a rotation drive mechanism 5 and is located below the transverse frame 1. Both ends of the mounting frame 4 are rotatably connected to a first linkage mechanism 6 and a second linkage mechanism 7. The first linkage mechanism 6 and the second linkage mechanism 7 extend upward and are driven by the lifting drive mechanism 3 to move up and down respectively.

[0036] The conveying mechanism 8 is located at the bottom of the mounting frame 4 and is driven by the rotary drive mechanism 5 to rotate horizontally. The conveying mechanism 8 is used to insert and take out corresponding goods. Specifically, in this embodiment, the goods are cotton rolls, and the rotary drive mechanism 5 is used to drive the conveying mechanism 8 to rotate 180°; the lifting drive mechanism 3 is used to drive the first linkage mechanism 6 and the second linkage mechanism 7 to move in the same direction to drive the mounting frame 4 and the conveying mechanism 8 to move up and down, or to drive the first linkage mechanism 6 and the second linkage mechanism 7 to move in opposite directions or one of them to move, so as to drive the mounting frame 4 and the conveying mechanism 8 to swing to an inclined setting.

[0037] The above structure is set up, and the two ends of the mounting frame 4 are connected by the first linkage mechanism 6 and the second linkage mechanism 7, so that the mounting frame 4 is stably suspended under the transverse frame 1, avoiding excessive shaking of the mounting frame 4 when the driving mechanism drives the conveying mechanism 8 to rotate, and lowering the installation position of the rotation driving mechanism 5, so as to improve the vertical space utilization rate under the transverse frame 1 and reduce the overall height of the equipment, saving vertical space, and the rotation driving mechanism 5 only needs to drive the conveying mechanism 8 to rotate, thereby reducing the rotational inertia, improving the rotational stability, avoiding excessive displacement of the goods on the conveying mechanism 8 during rotation, improving the regularity of cargo loading, and ensuring the space utilization rate of the carriage; and, through the addition of the first linkage mechanism 6 and the second linkage mechanism 7, the lifting drive mechanism 3 can drive the mounting frame 4 and the conveying mechanism 8 to stably The lifting and lowering function can be realized, and the conveying mechanism 8 can lift and transport the goods to the carriage to be unloaded, or after the conveying mechanism 8 inserts the goods, drive the mounting frame 4 and the conveying mechanism 8 to swing to the inclined setting, so that the goods can be tilted and slid down to be unloaded into the carriage to meet the loading requirements of the goods fitting tightly, or the goods can be tilted and moved inward on the conveying mechanism 8 to improve the stability of the conveying mechanism 8 in lifting and transporting. Therefore, without adding a new driving structure, the multifunctional drive of the lifting drive mechanism 3 is realized by adding the first linkage mechanism 6 and the second linkage mechanism 7 to reduce the driving cost, and the weight of the mounting frame 4, the rotating drive mechanism 5 and the conveying mechanism 8 is dispersedly transmitted to the lifting drive mechanism 3 through the first linkage mechanism 6 and the second linkage mechanism 7, so as to avoid the concentration of force on the lifting drive mechanism 3 and improve the driving stability.

[0038] In order to further reduce the overall height of the equipment, the lifting drive mechanism 3 includes a fixed frame 31 installed on the inner side of the transverse frame 1, and a lifting electric cylinder 32 fixed in the fixed frame 31 in the front and rear distributions. The first linkage mechanism 6 and the second linkage mechanism 7 have the same structure and are symmetrically arranged. The first linkage mechanism 6 includes several levels of telescopic frames that are slidably sleeved and linked to each other from top to bottom. The highest-level telescopic frame is slidably sleeved with the fixed frame 31 and is respectively connected to the telescopic rod 321 of the corresponding lifting electric cylinder 32. The lowest-level telescopic frames of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the front and rear ends of the mounting frame 4. The rotation drive mechanism 5 is arranged in the middle of the mounting frame 4 and between the lowest-level telescopic frames on the front and rear sides. Specifically, the rotation drive mechanism 5 includes a rotating ring gear 51 that rotates through the middle of the mounting frame 4, and a rotating electric cylinder 52 that is mounted on the top of the mounting frame 4 and whose rotation output end is engaged with the inner side of the rotating ring gear 51 through a driving gear. By setting the first linkage mechanism 6 and the second linkage mechanism 7 to slide and sleeve in stages from top to bottom and link and telescope in several stages, the connection points of the upper and lower ends of the lifting cylinder 32 are shortened from between the fixed frame 31 and the mounting frame 4 to between the fixed frame 31 and the highest-level telescopic frame, thereby ensuring that the first linkage mechanism 6 and the second linkage mechanism 7 drive the mounting frame 4 up and down, and greatly shortening the length of the required telescopic rod 321 of the lifting cylinder 32, shortening the overall length of the lifting cylinder 32, thereby improving the vertical structural compactness of the first linkage mechanism 6 and the second linkage mechanism 7, and further reducing the overall height of the equipment; at the same time, the rotating drive mechanism 5 is set in the middle of the mounting frame 4, which can improve the force balance between the first linkage mechanism 6 and the second linkage mechanism 7, further improve the stability of the mounting frame 4 suspended under the transverse frame 1, and the stability of the first linkage mechanism 6 and the second linkage mechanism 7 driving the mounting frame 4 to rise or fall or tilt.

[0039] In order to further improve the lifting and tilting stability of the mounting frame 4 and the transport mechanism 8, the several levels of the telescopic frames are, from top to bottom, a first-level frame 61, a second-level frame 62 and a third-level frame 63. The left and right outer sides of the first-level frame 61, the second-level frame 62 and the third-level frame 63 are respectively connected to the left and right inner sides of the fixed frame 31, the first-level frame 61 and the second-level frame 62 by guide sliders 64 and guide rails 65 for upward and downward sliding. Specifically, the left and right outer sides of the first-level frame 61, the second-level frame 62 and the third-level frame 63 are respectively fixed with guide rails 65, and the left and right inner sides of the fixed frame 31, the first-level frame 61 and the second-level frame 62 are respectively fixed with several guide sliders 64 that are slidably arranged with the corresponding guide rails 65. In other embodiments, the up and down sliding connection can also be achieved through guide rails 65 and rollers. The corresponding telescopic rods 321 are respectively connected to the middle side of the first-level frame 61 of the first linkage mechanism 6 and the second linkage mechanism 7, and the left and right lower ends of the third-level frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the left and right sides of the front and rear top of the mounting frame 4 to form a four-corner connection. The four corners of the mounting frame 4 are hingedly connected by two or three-stage frames 63, thereby improving the connection strength between the two, and thus improving the stability of the mounting frame 4 suspended in the transverse frame 1, further avoiding excessive shaking of the mounting frame 4 when the driving mechanism drives the conveying mechanism 8 to rotate, and multi-stage overlapping guidance is performed by the guide sliders 64 and guide rails 65 between the fixed frame 31, the first-stage frame 61, the second-stage frame 62, and the third-stage frame 63, to achieve four-side vertical stable and high-precision guidance, ensuring the stability of the first linkage mechanism 6 and the second linkage mechanism 7 in driving the mounting frame 4 and the conveying mechanism 8 to move up and down and swing to an inclined setting, especially avoiding the relative skew between the first-stage frame 61, the second-stage frame 62, and the third-stage frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 when the mounting frame 4 and the conveying mechanism 8 swing to an inclined setting, thereby avoiding the occurrence of structural damage caused by relative skewness, thereby improving the overall stability and reliability of the equipment.

[0040] In order to improve the connection strength between the three-stage frame 63 and the connecting member 4, the front and rear tops of the connecting member 4 are respectively detachably provided with reinforcing plates 41, and the left and right lower ends of the three-stage frame 63 of the first linkage mechanism 6 and the second linkage mechanism 7 are respectively hinged to the left and right ends of the two reinforcing plates 41.

[0041] In order to realize the linkage extension and retraction between the first-stage frame 61, the second-stage frame 62, and the third-stage frame 63, while extending the extension stroke to increase the lifting stroke, the first linkage mechanism 6 also includes a first-stage linkage component 66 and a second-stage linkage component 67. The first-stage linkage component 66 includes a plurality of first-stage sprockets 661 rotatably arranged on the upper part of the first-stage frame 61, and a first-stage chain 662 connected to the lower part of the second-stage frame 62 at one end after passing through a plurality of the first-stage sprockets 661 respectively, and the plurality of first-stage sprockets 661 are higher than the lower end of the fixed frame 31 and the other ends of the plurality of first-stage chains 662 are fixed to the lower end of the fixed frame 31. The second-stage linkage component 67 includes a plurality of second-stage sprockets 671 rotatably arranged on the upper part of the second-stage frame 62, and a plurality of second-stage sprockets 671 are higher than the lower end of the first-stage frame 61 and the other ends of the plurality of second-stage chains 672 are fixed to the lower end of the first-stage frame 61. When the lifting cylinder 32 drives the first frame 61 and the first sprockets 661 to rise, the second frame 62 and the second sprockets 671 are lifted by the first chains 662 and gradually retracted into the first frame 61. At the same time, the second frame 62 lifts the third frame 63 by the second chains 672 and gradually retracts into the second frame 62. When the lifting cylinder 32 drives the first frame 61 and the first sprockets 661 to descend, the second frame 62 and the second sprockets 671 are lowered by the first chains 662 and gradually extend downward. At the same time, the second frame 62 is lifted by the second chains 672 and gradually retracted into the second frame 62. A number of secondary chains 672 are lowered to the tertiary frame 63 and gradually extended downward, thereby realizing the linkage extension and retraction between the primary frame 61, the secondary frame 62, and the tertiary frame 63. On this basis, by installing the primary sprocket 661 and the secondary sprocket 671 at the high position of the primary frame 61 and the secondary frame 62, and connecting one end of the chain and the secondary chain 672 to the low position of the secondary frame 62 and the tertiary frame 63, the linkage extension and retraction stroke of the secondary frame 62 and the tertiary frame 63 is increased, and a larger range of lifting and lowering stroke is achieved under the premise that the secondary frame 62 and the tertiary frame 63 are the same length.

[0042] Several cotton rolls are placed in an array layer by layer on multi-layer comb-tooth shelves. Currently, the cotton rolls are mainly loaded by manually driving a forklift to stack the cotton rolls, insert them into the vehicle flatbed, and then manually stack the cotton rolls one by one on the vehicle. This loading method has problems such as low efficiency, high labor costs, and insufficient loading accuracy.

[0043] The cam 83 is connected to the rear of the vehicle 81 so that the vehicle 81 can be rotated to move horizontally along the cam 82. The cam 83 is connected to the rear of the vehicle 81 so that the vehicle 81 can be rotated to move horizontally along the cam 82. After several rows of insertion rods 841 are inserted into the multi-layer comb-tooth shelves to lift several layers of cotton rolls into the carriage, the mounting frame 4 and the conveying mechanism 8 are driven to tilt until the ends of the several insertion rods 841 swing down, and then the push-pull frame 83 is driven to drive the conveying frame 84 to pull away from the several layers of cotton rolls in the direction away from the baffle 82, so that the several layers of cotton rolls are pushed by the baffle 82 and fall into the carriage, thereby completing the loading of several layers of cotton rolls, and the pushing and blocking effect of the baffle 82 realizes the stable stacking and loading of several layers of cotton rolls, which greatly saves labor costs and loading speed.

[0044] In order to improve the connection strength between the transport frame 84 and the push-pull frame 83, the push-pull frame 83 includes a sliding frame 831 whose left and right inner sides are slidably connected to the left and right outer sides of the rotating seat 81, a connecting rod 832 that is detachably provided on the rear side of the transport frame 84 and vertically connected to the left and right bottom sides of the sliding frame 831, and a reinforcing rod 833 that connects the connecting rod 832 and the rear end of the sliding frame 831. The sliding frame 831, the connecting rod 832, and the reinforcing rod 833 form a right-angled triangle structure. Specifically, the left and right inner sides of the sliding frame 831 are slidably connected to the left and right outer sides of the rotating seat 81 via sliding rails and sliders extending forward and backward. Thus, the right-angled triangle structure formed by the sliding frame 831, the connecting rod 832, and the reinforcing rod 833 improves the connection strength between the transport frame 84 and the push-pull frame 83, while the reinforcing rod 833 improves the structural strength of the connecting rod 832, thereby improving the supporting stability of the connecting rod 832 when several rows of insertion rods 841 are inserted to lift the cotton rolls and subjected to force.

[0045] In order to improve the connection strength between the plurality of insertion rods 841 and the carrying frame 84, the other end of the plurality of insertion rods 841 penetrates through the carrying frame 84 and is connected with a limiting block 842, one end of the limiting block 842 extends transversely and is detachably arranged with the carrying frame 84, specifically, one end of the limiting block 842 is screw-connected with the carrying frame 84. Thus, the connection area between the other end of the insertion rod 841 and the carrying frame 84 is improved by the addition of the limiting block 842, the connection strength between the insertion rod 841 and the carrying frame 84 is improved, meanwhile, the insertion rod 841 penetrates through the carrying frame 84 and the baffle 82 respectively, so that the other end of the insertion rod 841 is double-supported by the carrying frame 84 and the baffle 82 after the insertion rod 841 picks up the goods, the supporting strength of the insertion rod 841 is improved, and the risk of bending of the insertion rod 841 under pressure is reduced.

[0046] In order to adapt to the left and right changes of the loading position caused by different carriage widths or parking deviations of different models of vehicles, the front and rear sides of the fixed frame 31 are left and right slidingly connected with the top front and rear sides of the transverse frame 1, the top of the transverse frame 1 is provided with an adjusting driving mechanism 9 for driving the left and right transverse movement of the fixed frame 31, specifically, the front and rear sides of the fixed frame 31 are left and right slidingly connected with the top front and rear sides of the transverse frame 1 through left and right extending slide rails and slide blocks, the adjusting driving mechanism 9 is a gas cylinder, in the embodiment, the transverse frame 1 and the carrying mechanism 8 are respectively provided with a plurality of position sensors for detecting and positioning to assist the driving mechanisms to carry the goods to the specified position in the carriage, and an angle sensor for detecting the inclination angle of the carrying mechanism 8, and each sensor and driving mechanism is controlled by the control system to receive signals and control outputs, the specific control of the control system is the prior art and is not the main point of the application, and will not be repeated here. Thus, the left and right transverse movement of the fixed frame 31 can be driven by the adjusting driving mechanism 9 to drive the mounting frame 4 and the carrying mechanism 8 to move left and right through the first linkage mechanism 6 and the second linkage mechanism 7, so as to adjust the left and right stacking position of the goods in the carriage, so as to adapt to the left and right changes of the loading position caused by different carriage widths or parking deviations, and improve the adaptability of the equipment to load.

[0047] Working principle:

[0048] The cotton rolls and the vehicle are respectively located at the front and rear sides of the transport mechanism 8, and the lifting drive mechanism 3 drives the first linkage mechanism 6 and the second linkage mechanism 7 to descend synchronously, so as to drive the mounting frame 4 and the transport mechanism 8 to descend corresponding to the cotton rolls. After the transverse frame 1 moves forward until several rows of insertion rods 841 are inserted into the multi-layer comb rack, the lifting drive mechanism 3 drives the first linkage mechanism 6 and the second linkage mechanism 7 to rise synchronously, so as to drive the mounting frame 4 and the transport mechanism 8 to rise. Several rows of insertion rods 841 lift several layers of cotton rolls out of the multi-layer comb rack, the transverse frame 1 moves backward and the rotation drive mechanism 5 drives the transport mechanism 8 to rotate 180° so that several layers of cotton rolls correspond to the vehicle compartment, and the transverse frame After the transport mechanism 8 enters the carriage, the fixing frame 31 moves horizontally left and right, and the transport mechanism 8 is lowered to the loading position, the lifting drive mechanism 3 drives the first linkage mechanism 6 to rise slightly and the second linkage mechanism 7 to fall slightly, or drives the first linkage mechanism 6 to rise a distance or the second linkage mechanism 7 to fall a distance, so as to drive the mounting frame 4 and the transport mechanism 8 to swing to an inclined position with the front higher and the back lower so that the ends of the plurality of insertion rods 841 swing downward, and then drive the push-pull frame 83 to drive the transport frame 84 to pull away from the baffle 82 to separate from the plurality of layers of cotton rolls, so that the plurality of layers of cotton rolls are pushed by the baffle 82 and fall into the carriage, thereby completing the loading of the plurality of layers of cotton rolls.
