Description

Technical Field

[0001] This invention belongs to the field of suspended transportation, specifically relating to an intelligent suspended conveying system for centralized feeding of stretch film. Background Technology

[0002] During the production of stretch film, transport containers filled with stretch film raw materials need to be transported from the raw material storage area to the workstation to achieve centralized material supply for the production line.

[0003] Patent publication number CN223983007U relates to an intelligent suspended conveyor line for beverage production, comprising: a suspension guide rail, a moving trolley, a trolley drive chain, and a fixing fixture. The suspension guide rail is suspended and installed, and the moving trolley is mounted on the suspension guide rail and guided and limited by the suspension guide rail. The trolley drive chain is located above the suspension guide rail. The fixing fixture includes a supporting suspension bolt installed at the bottom of the moving trolley. An extension rod is provided at the lower end of the supporting suspension bolt, and a connecting limiting plate is provided at the lower end of the extension rod. Several elastic clamping pieces are arranged in a circular array around the axis of the connecting limiting plate. In use, by setting several elastic clamping pieces at the bottom of the connecting limiting plate and equidistantly circumferentially arranging all elastic clamping pieces, a clamping space with a circular inner diameter is formed. The elastic clamping pieces apply pressure to the upper part of the outer surface of the bottle or can through deformation pressure, thereby achieving clamping and fixing of the beverage bottle or can.

[0004] In existing technology, by setting several elastic clips at the bottom of the connecting limiting plate and arranging all elastic clips in an equidistant circular array to form a clamping space with a circular inner diameter, the elastic clips apply pressure to the upper part of the outer surface of the bottle or can through deformation pressure, thereby achieving the clamping and fixing of the beverage bottle or can. However, the filling of the wrapping film material inside the transport barrel is uneven, and the transport barrel is prone to tilting during suspended transport. In the tilted state, the barrel body is prone to collision and deformation. Furthermore, when the transport barrel is heavy, the hook will bend due to long-term heavy load, causing the transport barrel to fall. At the same time, when the transport barrel is overloaded, it is easy to cause overload damage to the transport equipment, resulting in the interruption of the suspended transport operation. Summary of the Invention

[0005] Various embodiments of the disclosed technology involve an intelligent suspended conveying system for centralized feeding of stretch film, which can automatically push the suspension frame to the center position, thereby realizing the automatic centered suspension of the transport bucket, avoiding the tilting of the transport bucket caused by feeding deviation, which may lead to the bucket body being bumped, deformed or falling, and ensuring the continuity of the suspended transport of the transport bucket.

[0006] According to the embodiments of the disclosed technology, an intelligent suspended conveying system for centralized feeding of stretch film includes a transport rail, a transport device is provided at the bottom of the transport rail, a transport frame is slidably installed on the inner wall of the transport device, a suspension plate is fixedly installed on the inner wall of the transport frame, and a suspension assembly is also included. The suspension assembly includes a hollow frame, a solid frame, a hook, a feeding roller, an anti-skewing frame, an anti-skewing spring, an anti-skewing roller, an anti-skewing block, and a suspension frame. The hollow frame is fixedly installed at the bottom of the suspension plate, the solid frame is slidably installed on the inner wall of the hollow frame, the hook is fixedly installed at the bottom of the solid frame, the feeding roller is rotatably installed on the right side of the hook, the anti-skewing frame slides through the bottom of the hook, the anti-skewing spring is disposed between the hook and the anti-skewing frame, the anti-skewing roller is rotatably installed on the inner wall of the anti-skewing frame, the anti-skewing block slides through the left and right walls of the hook, and the suspension frame is disposed at the bottom of the inner wall of the hook. The suspension frame contacts and squeezes the feeding roller to generate rotation. The rotation of the feeding roller facilitates loading and unloading of materials between the suspension frame and the transport bucket, reduces friction between the suspension frame and the hook, and allows for easy adjustment of the suspension position of the suspension frame when there is a large deviation.

[0007] In some implementations, a spring is provided between the hollow frame and the solid frame, which can drive the hollow frame to reset. A spring is provided between the anti-tilt block and the hook, which can drive the anti-tilt block to reset. The right side of the hook is set as an inclined surface, which can reduce the friction when the hook contacts the suspension frame. A transport bucket is provided at the bottom of the suspension frame, and the transport bucket contains stretch film material. A weight-limiting spring is provided between the transport frame and the transport equipment, which can support the transport equipment.

[0008] In some implementations, the suspension frame abuts against the top right side of the anti-tilt frame, the left side of the anti-tilt block is set as an inclined surface, the anti-tilt block abuts against the anti-tilt roller, the support assembly is used to support the hook, the weight limiting assembly is used to prevent the transport bucket from being overweight, and the anti-tilt block moves to the right and contacts the inclined surface of the suspension frame and squeezes the suspension frame, and the suspension frame moves towards the center under the squeezing of the anti-tilt block.

[0009] In some implementations, a support component and a weight-limiting component are also included. The support component includes a slide plate, a shield, a load-bearing frame, a support frame, and a support groove. The slide plate is slidably mounted on the bottom of the suspension plate. The shield is fixedly mounted on the bottom of the slide plate. The load-bearing frame is fixedly mounted on the left side of the solid frame. The support frame is slidably mounted on the inner wall of the load-bearing frame. The support groove is opened on the left side of the hollow frame. When the slide plate moves towards the transport bucket, it causes the shield to move towards the transport bucket. The shield moves towards the transport bucket to shield the transport bucket, thereby preventing the transport bucket from swaying when turning.

[0010] In some implementations, the top right side of the support frame is set as an inclined surface. Setting the top right side of the support frame as an inclined surface can reduce the friction when the support frame contacts the support groove. The inner wall of the shielding frame is set as an arc surface. Setting the inner wall of the shielding frame as an arc surface can make the shielding frame fit the transport barrel more closely. The support frame abuts against the hollow frame. A spring is set between the sliding plate and the suspension plate. The spring can drive the sliding plate to return to its original position. The support frame moves to the right under the elastic force of the support spring. When the support frame moves to the right, it will contact the inner wall of the support groove and limit the solid frame. At the same time, when the support frame moves to the right, it will contact the bottom of the hook and support the hook.

[0011] In some implementations, a support spring is provided between the support frame and the solid frame. After the support frame is aligned with the support groove, the support frame moves to the right under the elastic force of the support spring. The top of the solid frame is set as an inclined surface, and the sliding plate abuts against the solid frame.

[0012] In some implementations, the weight-limiting component includes a toothed block plate, a gear, a rack plate, a linear damper, a limiting frame, and a limiting groove. The toothed block plate is fixedly installed on the rear side of the transport frame, the gear is rotatably installed on the inner wall of the transport equipment, the rack plate slides through the top of the transport equipment, the linear damper is disposed between the rack plate and the transport equipment, the limiting frame is fixedly installed on the top of the inner wall of the transport rail, and the limiting groove is opened at the bottom of the limiting frame. When the toothed block plate moves downward, it will drive the gear to rotate clockwise, and the clockwise rotation of the gear will drive the rack plate to move upward. When the rack plate moves upward, it will contact the limiting groove and limit the transport equipment.

[0013] In some implementations, a spring is provided between the gear and the transport equipment. The spring can drive the gear to reset. The toothed block plate meshes with the gear, and the rack plate meshes with the gear. The free end of the linear damper moves slowly upward, causing the rack plate to move slowly upward, thereby preventing the transport equipment from vertically swaying under overload conditions.

[0014] This invention provides an intelligent overhead conveyor system for centralized feeding of stretch film. It offers the following advantages: 1. This invention facilitates loading and unloading of the suspension frame and transport bucket by rotating the loading roller, thereby reducing loading and unloading resistance and improving the loading and unloading efficiency of the suspension transport. At the same time, the rotation of the loading roller can facilitate the adjustment of the suspension position of the suspension frame, thereby reducing the difficulty of loading operation and further accelerating the efficiency of suspension transport. By being squeezed towards the center by the anti-tilt block, the suspension frame can be automatically pushed to the center position, thereby realizing the automatic centering of the transport bucket and avoiding the tilting of the transport bucket due to loading deviation, which may cause the bucket to be bumped, deformed or fall off, thus ensuring the continuity of the suspension transport of the transport bucket.

[0015] 2. This invention uses a shielding frame that moves closer to the transport container to shield it, thereby limiting the lateral swaying of the transport container and preventing it from shaking and hitting the frame during turns, thus further preventing the spillage of materials inside the transport container.

[0016] 3. In this invention, the support frame moves to the right and contacts the bottom of the hook, thus supporting the hook. Lighter transport buckets only trigger the shield to assist in anti-swaying, while heavier transport buckets will cause the suspension frame to move down a greater distance, thereby triggering the support frame to pop out and support the hook from the bottom, reducing the risk of hook bending or breaking and further improving the load-bearing capacity of the hook.

[0017] 4. This invention allows the rack plate to move upward and contact the limiting groove, thus limiting the transport equipment. The transport equipment cannot move due to the limitation of the rack plate, thereby realizing automatic overload limiting. This can prevent overloaded transport barrels from being put into suspended transport, further avoiding equipment damage and falling hazards caused by overload.

[0018] 5. This invention, by slowly moving the free end of the linear damper upward, causes the rack plate to move upward slowly, thereby avoiding vertical swaying caused by instantaneous locking of the transport equipment and improving the safety of the transport equipment under overload conditions.

[0021] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] like Figures 1 to 8 As shown, an intelligent overhead conveying system for centralized feeding of stretch film in this embodiment includes a transport rail 1, a transport device 2 at the bottom of the transport rail 1, a transport frame 3 slidably installed on the inner wall of the transport device 2, a suspension plate 4 fixedly installed on the inner wall of the transport frame 3, and a suspension assembly. The suspension assembly includes a hollow frame 5, a solid frame 6, a hook 7, a feeding roller 8, an anti-skewing frame 9, an anti-skewing spring 10, an anti-skewing roller 11, an anti-skewing block 12, and a suspension frame 13. The hollow frame 5 is fixedly installed at the bottom of the suspension plate 4. The solid frame 6 is slidably installed on the inner wall of the hollow frame 5. The hook 7 is fixedly installed at the bottom of the solid frame 6. The feeding roller 8 is rotatably installed on the right side of the hook 7. The anti-skewing frame 9 slides through the bottom of the hook 7. The anti-skewing spring 10 is located between the hook 7 and the anti-skewing frame 9. The anti-skewing roller 11 is rotatably installed on the inner wall of the anti-skewing frame 9. The anti-skewing block 12 slides through the left and right walls of the hook 7. The suspension frame 13 is located at the bottom of the inner wall of the hook 7. The rotation of the feeding roller 8 facilitates loading and unloading of the suspension frame 13 and the transport bucket, thereby reducing loading and unloading resistance and improving the loading and unloading efficiency of the suspended transport. At the same time, the rotation of the feeding roller 8 facilitates the adjustment of the suspension position of the suspension frame 13, thereby reducing the difficulty of loading operations and further accelerating the efficiency of the suspended transport.

[0023] A spring is installed between the hollow frame 5 and the solid frame 6. The hollow frame 5 can be reset by the spring. A spring is installed between the anti-tilt block 12 and the hook 7. The anti-tilt block 12 can be reset by the spring. The right side of the hook 7 is set as an inclined surface. The inclined surface on the right side of the hook 7 can reduce the friction when the hook 7 contacts the suspension frame 13. A transport bucket is installed at the bottom of the suspension frame 13. The transport bucket contains stretch film material. A weight-limiting spring is installed between the transport frame 3 and the transport equipment 2. The weight-limiting spring can support the transport equipment 2 and is used to sense the load.

[0024] The suspension frame 13 abuts against the top right side of the anti-tilt frame 9. The left side of the anti-tilt block 12 is set as an inclined surface. The anti-tilt block 12 abuts against the anti-tilt roller 11. The support component is used to support the hook 7. The weight limiting component is used to prevent the transport bucket from being overweight. When the anti-tilt block 12 moves to the right, it will contact the inclined surface of the suspension frame 13 and squeeze the suspension frame 13. The suspension frame 13 moves towards the center under the squeezing of the anti-tilt block 12. It can automatically push the suspension frame 13 to the center position, thereby realizing the automatic centering and suspension of the transport bucket. This avoids the tilting of the transport bucket caused by the feeding deviation, which may cause the bucket to be bumped, deformed or fall off, and ensures the continuity of the suspended transport of the transport bucket.

[0025] In this embodiment, during the process of placing the suspension frame 13 along with the transport bucket into the bottom of the inner wall of the hook 7, the suspension frame 13 will contact and squeeze the feeding roller 8 to generate rotation. The rotation of the feeding roller 8 can facilitate the loading and unloading of the suspension frame 13 and the transport bucket, reduce the friction between the suspension frame 13 and the hook 7, and when the suspension frame 13 has a large deviation, the rotation of the feeding roller 8 can facilitate the adjustment of the suspension position of the suspension frame 13. Moreover, when the suspension frame 13 is placed into the inner wall of the hook 7, the suspension frame 13 will drive the hook 7 to move downward under the action of the weight of the transport bucket. The downward movement of the hook 7 will drive the solid frame 6 to move downward. The downward movement of the solid frame 6 will pull the spring to deform and store force. The deformation and storage of force of the spring can buffer the suspension frame 13 and the transport bucket. At the same time, the suspension frame 13 will contact the anti-tilt frame 9 when placed into the inner wall of the hook 7 and squeeze the anti-tilt frame 9. The anti-skewing frame 9 moves downward under the pressure of the suspension frame 13. The downward movement of the anti-skewing frame 9 will compress the anti-skewing spring 10, causing it to deform and store force. At the same time, the downward movement of the anti-skewing frame 9 will drive the anti-skewing roller 11 to move downward. The downward movement of the anti-skewing roller 11 will contact the inclined surface of the anti-skewing block 12 and compress the anti-skewing block 12. The anti-skewing block 12 moves to the right under the pressure of the anti-skewing roller 11. The rightward movement of the anti-skewing block 12 will contact the inclined surface of the suspension frame 13 and compress the suspension frame 13. The suspension frame 13 moves towards the center under the pressure of the anti-skewing block 12, so that the suspension frame 13 and the transport barrel are in the center position during suspension and transport. To prevent the suspension frame 13 and the transport bucket from tilting during transport, when the suspension frame 13 and the transport bucket are transported to the unloading point, lift the transport bucket and the suspension frame 13 upward and push the transport bucket to the right. Then the transport bucket and the suspension frame 13 can be removed. The upward movement of the suspension frame 13 will disengage from the anti-tilt frame 9, causing the anti-tilt frame 9 to move upward and reset under the elastic force of the anti-tilt spring 10. The upward reset of the anti-tilt frame 9 will drive the anti-tilt roller 11 to move upward and reset. The upward reset of the anti-tilt roller 11 will disengage from the anti-tilt block 12, causing the anti-tilt block 12 to move to the right and reset under the elastic force of the second spring. Example

[0026] like Figures 1 to 8 As shown, this embodiment of the intelligent suspended conveyor system for centralized feeding of stretch film includes all the technical features of Embodiment 1. In addition, it also includes a support component and a weight limiting component. The support component includes a slide plate 141, a shielding frame 142, a load-bearing frame 143, a support frame 144, and a support groove 146. The slide plate 141 is slidably installed on the bottom of the suspension plate 4. The shielding frame 142 is fixedly installed on the bottom of the slide plate 141. The load-bearing frame 143 is fixedly installed on the left side of the solid frame 6. The support frame 144 is slidably installed on the inner wall of the load-bearing frame 143. The support groove 146 is opened on the left side of the hollow frame 5. By moving the shielding frame 142 towards the transport barrel to shield the transport barrel, the left and right swing of the transport barrel is restricted, thereby avoiding the transport barrel shaking and hitting the frame during the turn, and further preventing the material inside the transport barrel from spilling.

[0027] The top right side of the support frame 144 is sloped to reduce friction when the support frame 144 contacts the support groove 146. The inner wall of the shielding frame 142 is curved to allow it to fit the transport barrel more closely. The support frame 144 abuts against the hollow frame 5. A spring 3 is installed between the slide plate 141 and the suspension plate 4, which can reset the slide plate 141. The support frame 144 is supported by the spring 145. Under the action of force, the support frame 144 moves to the right and contacts the inner wall of the support groove 146, limiting the solid frame 6. At the same time, the support frame 144 moves to the right and contacts the bottom of the hook 7, supporting the hook 7. The lighter transport bucket only triggers the shield 142 to assist in anti-swaying. The heavier transport bucket will cause the suspension frame 13 to move down a greater distance, thereby triggering the support frame 144 to pop out and support the hook 7 from the bottom, reducing the risk of the hook 7 bending or breaking, and further improving the load-bearing capacity of the hook 7.

[0028] A support spring 145 is provided between the support frame 144 and the solid frame 6. After the support frame 144 is aligned with the support groove 146, the support frame 144 moves to the right under the elastic force of the support spring 145. The top of the solid frame 6 is set as an inclined surface, and the slide plate 141 abuts against the solid frame 6.

[0029] The weight limiting component includes a toothed plate 151, a gear 152, a rack 153, a linear damper 154, a limiting frame 155, and a limiting groove 156. The toothed plate 151 is fixedly installed on the rear side of the transport frame 3. The gear 152 is rotatably installed on the inner wall of the transport equipment 2. The rack 153 slides through the top of the transport equipment 2. The linear damper 154 is located between the rack 153 and the transport equipment 2. The limiting frame 155 is fixedly installed on the top of the inner wall of the transport rail 1. The limiting groove 156 is opened at the bottom of the limiting frame 155. The transport equipment 2 is limited by the rack 153 and cannot move, thereby realizing automatic overweight limiting. This can prevent overweight transport barrels from being put into suspended transport, further avoiding equipment damage and falling hazards caused by overweight.

[0030] A spring is installed between gear 152 and transport device 2. The spring can drive gear 152 to reset, toothed plate 151 meshes with gear 152, and rack plate 153 meshes with gear 152. The free end of linear damper 154 moves slowly upward, causing rack plate 153 to move slowly upward, thereby preventing vertical swaying of transport device 2 under overload conditions. The slow upward movement of rack plate 153 also prevents vertical swaying caused by instantaneous locking of transport device 2, improving the safety of transport device 2 under overload conditions. In this embodiment, when the solid frame 6 moves downward, it will disengage from the sliding plate 141 and release the restriction on the sliding plate 141. After the restriction on the sliding plate 141 is released, the sliding plate 141 moves towards the transport barrel under the elastic force of the spring three. The movement of the sliding plate 141 towards the transport barrel will drive the shielding frame 142 to move towards the transport barrel. The shielding frame 142 moves towards the transport barrel to shield the transport barrel, thereby preventing the transport barrel from swaying when turning. This is especially useful when transporting heavy transport barrels. The heavier transport bucket, under its own weight, causes the suspension frame 13 to move downward a considerable distance. The downward movement of the suspension frame 13 causes the solid frame 6 to move downward. The downward movement of the solid frame 6 causes the support groove 146 to align with the support frame 144. After the support frame 144 aligns with the support groove 146, the support frame 144 moves to the right under the elastic force of the support spring 145. The rightward movement of the support frame 144 will contact the inner wall of the support groove 146 and limit the solid frame 6. At the same time, the rightward movement of the support frame 144 will contact the bottom of the hook 7 and support the hook 7.

[0031] When the transport container is severely overloaded, the suspension plate 4 and the transport frame 3 will move downwards a short distance. The downward movement of the transport frame 3 will pull the weight-limiting spring. The weight-limiting spring will deform and store force due to the pull of the transport frame 3. At the same time, the downward movement of the transport frame 3 will drive the toothed block plate 151 to move downwards. The downward movement of the toothed block plate 151 will drive the gear 152 to rotate clockwise. The clockwise rotation of the gear 152 will drive the rack plate 153 to move upwards. When the rack plate 153 moves upward, it will contact the limiting groove 156 and limit the transport equipment 2. The transport equipment 2 cannot move due to the limitation of the rack plate 153, thus prompting the operator that the transport bucket is overweight. At the same time, the upward movement of the rack plate 153 will drive the free end of the linear damper 154 to move slowly upward. The slow upward movement of the free end of the linear damper 154 causes the rack plate 153 to move slowly upward, thereby preventing the transport equipment 2 from vertically swaying when overweight or when the transport bucket is removed.

[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0033] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Any changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
