Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a device for feeding a long cylindrical conveyor and vacuum stretch film after material handling. It is mainly used in the automated material handling and vacuum stretch film feeding process of long cylindrical products (such as ham) in the food and other industries. Background Technology

[0002] In the ham production process, the whole ham is cut into long cylindrical products of the same specifications. The two products have dimensions of ø65×L165 and ø60×L140 respectively, and the center distance between the two products is the same when placed on the vacuum stretch film packaging machine. In the current production mode, the cut hams need to be manually gathered into a transfer frame and then transferred to the vacuum stretch film machine for manual placement. This manual operation method is not only time-consuming and labor-intensive, but also makes it difficult to guarantee the feeding efficiency.

[0003] This shows that existing technologies still have certain shortcomings. Therefore, there is an urgent need for a device that can achieve automated and efficient material handling and feeding. Utility Model Content

[0004] The purpose of this invention is to provide a device for feeding vacuum stretch film after conveying and sorting materials in a long cylindrical conveyor, so as to solve the problems of time-consuming and labor-intensive manual operation and difficulty in ensuring feeding efficiency.

[0005] To achieve the above objectives, this utility model provides a long cylindrical conveyor for feeding vacuum stretch film, comprising a differential speed conveyor, a baffle synchronous belt, a product synchronous conveyor belt, a gripping and sorting device, and a transfer robot connected in sequence; the conveying directions of the differential speed conveyor and the product synchronous conveyor belt are parallel, and the conveying direction of the baffle synchronous belt is perpendicular to the conveying directions of the differential speed conveyor and the product synchronous conveyor belt; the differential speed conveyor includes at least two conveyor belts in the same direction but with different conveying speeds, and the baffle synchronous belt receives material from the differential speed conveyor; it also includes a baffle pushing device connected in cooperation with the baffle synchronous belt, which pushes the material carried by the baffle synchronous belt to the product synchronous conveyor belt, and the product synchronous conveyor belt receives the material from the baffle synchronous belt and conveys it to the gripping and sorting device; the transfer robot is disposed on the side of the gripping and sorting device.

[0006] The above structure enables automated feeding and conveying of elongated cylindrical materials (such as ham blanks), and simultaneously allows for material handling during the automated feeding and conveying process. This allows the elongated cylindrical materials to be directly fed to the processing station of the vacuum stretch film packaging device. No additional adjustments are required after feeding, facilitating direct packaging of the elongated cylindrical materials by the subsequent vacuum stretch film packaging device. Compared to traditional manual feeding and handling methods and existing feeding devices that only achieve automatic feeding, this effectively improves production efficiency and quality. Furthermore, reducing manual intervention directly reduces safety risks for production personnel during equipment operation. Moreover, the differential speed conveyor, the synchronous belt, and the product synchronous conveyor belt in the above solution have a simple cooperative structure and flexible arrangement, easily adapting to actual installation space limitations, effectively enhancing the adaptability and versatility of the feeding device in this application.

[0007] In a preferred embodiment of this application, along the conveying direction of the baffle synchronous belt, the baffle synchronous belt has a plurality of spaced material carrying positions, and the product synchronous conveyor belt has a plurality of parallel conveying channels, with the material carrying positions corresponding one-to-one with the conveying channels.

[0008] In the above scheme, the radial separation of multiple long cylindrical materials can be achieved through the cooperation of the baffle synchronous belt and the product synchronous conveyor belt during the conveying process. This ensures that the long cylindrical materials meet the material placement requirements of the vacuum stretch film packaging device during the conveying process, facilitating direct feeding. Furthermore, the baffle synchronous belt in the above scheme can directly utilize the intervals set on the baffle synchronous belt as material bearing positions to achieve radial separation of multiple materials. Moreover, the baffle synchronous belt and the product synchronous conveyor belt have simple structures, are easy to cooperate and adjust, and can flexibly adjust the specifications and cooperation methods of the baffle synchronous belt and the product synchronous conveyor belt according to the feeding requirements of different specifications of vacuum stretch film packaging devices.

[0009] In a preferred embodiment of this application, the baffle pusher includes a pusher plate and a pusher plate drive device connected to the pusher plate. By setting the pusher plate drive device to achieve automatic material pushing, the material transfer efficiency between the baffle synchronous belt and the product synchronous conveyor belt is improved, thereby increasing the feeding efficiency.

[0010] In a preferred embodiment of this application, the gripping and material handling device includes a support frame and a material handling platform disposed on the upper part of the support frame. The material handling platform includes a plurality of conveying rollers and a roller drive device connected to the conveying rollers. A plurality of recesses are provided on the conveying rollers along the axial direction, and the recesses are provided one-to-one with the conveying channels.

[0011] In the above scheme, the material handling platform uses conveyor rollers for material transport at the end of the loading stage instead of continuing with the synchronous conveyor belt. This allows for secondary radial material handling via recesses on the conveyor rollers, ensuring the radial spacing between materials meets the loading requirements of the vacuum stretch film packaging device. Furthermore, the gaps between the conveyor rollers can be used to create blocking structures for axial material handling, thus adapting to the processing rhythm of the vacuum stretch film packaging device and further improving loading and processing efficiency. Additionally, the rigid conveyor structure of the conveyor rollers provides ample support for the materials, facilitating material gripping in conjunction with the transfer robot.

[0012] In a preferred embodiment of this application, the roller drive device includes a stepper motor, a transmission belt, and a transmission pulley disposed at the end of the conveying roller shaft. The transmission pulley is disposed in a one-to-one correspondence with the conveying roller shaft, and the stepper motor is connected to the conveying roller shaft through the transmission belt and the transmission pulley.

[0013] In the above scheme, the cooperation structure between the stepper motor, transmission belt, transmission pulley and conveyor roller shaft is simple and mature and the transmission is reliable. It is highly maintainable and has low maintenance cost in actual use. The stepper motor has the advantages of sensitive response and convenient control. The conveying rhythm of the conveyor roller shaft can be adjusted by adjusting the start and stop rhythm of the stepper motor to further adapt to the processing rhythm of the vacuum stretch film packaging device.

[0014] In a preferred embodiment of this application, the surface of the conveying roller shaft is provided with an anti-corrosion and wear-resistant coating.

[0015] In the above solution, by applying an anti-corrosion and wear-resistant coating, the corrosion and wear resistance of the conveyor rollers can be improved, reducing wear during use and extending their service life. Furthermore, by ensuring the surface quality of the conveyor rollers, damage to the material surface during conveying can be avoided, thus ensuring product quality. Preferably, the aforementioned anti-corrosion and wear-resistant coating can be a KNM1000 ceramic anti-corrosion and wear-resistant coating.

[0016] In a preferred embodiment of this application, the gripping and feeding device further includes a blocking mechanism, which includes a blocking member and a blocking drive mechanism connected to the blocking member. There is a blocking gap between two adjacent conveying rollers that allows the blocking member to pass through. The blocking member moves up and down in the vertical direction under the drive of the blocking drive mechanism, and at least a portion of the blocking member can pass through the blocking gap and rise above the feeding platform.

[0017] In the above solution, the cooperation between the blocking mechanism and the conveying roller shaft enables axial material handling of long cylindrical materials during the conveying process, adapting to the feeding rhythm of the vacuum stretch film packaging device. Moreover, the blocking mechanism has a simple structure, is easy to use, and has low operating and maintenance costs.

[0018] In a preferred embodiment of this application, the support frame includes a bracket, the material handling platform is mounted on the upper part of the bracket, the bracket also has a mounting part located below the material handling platform, the blocking mechanism is disposed in the mounting part, and the bottom of the bracket is also provided with double-hole feet.

[0019] By adopting the above structure, the barrier structure and the material handling platform are integrated on the support frame, which can make full use of the installation space on the support frame and shorten the stroke of the barrier component when performing the barrier operation, thereby improving the barrier response speed. By setting double-hole feet, the stability of the support frame can be improved, and a lifting connection structure can be used between the double-hole feet and the bracket to allow the support frame to adapt to changes in the terrain of the installation location.

[0020] In a preferred embodiment of this application, the gripping and feeding device further includes a material detection component, which includes multiple photoelectric detectors disposed on both sides of the feeding platform to monitor whether there is material on the feeding platform and the quantity of material.

[0021] In the above scheme, by setting up a material detection component, it is possible to facilitate automated feeding and sorting, and also to enable relevant production personnel to monitor the operation of the feeding device in real time, thereby ensuring the safe operation of the equipment.

[0022] In a preferred embodiment of this application, the end effector of the transfer robot is equipped with a suction cup gripper. The suction cup gripper includes a mounting plate and multiple suction cups mounted on the mounting plate, as well as gripping detection components corresponding to each suction cup. The gripping detection components are used to monitor whether the suction cups have gripped material. In the above solution, the use of a suction cup gripper instead of a traditional mechanical gripper helps to avoid damage to the surface of the material during the gripping process, and can better meet the requirements for gripping and transferring food materials.

[0035] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0036] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0037] like Figures 1-3As shown, this application provides a long cylindrical conveyor for feeding vacuum stretch film, which includes a differential speed conveyor 100, a baffle synchronous belt 200, a product synchronous conveyor belt 400, a gripping and sorting device 500, and a transfer robot 700 connected in sequence; the conveying directions of the differential speed conveyor 100 and the product synchronous conveyor belt 400 are parallel, and the conveying direction of the baffle synchronous belt 200 is perpendicular to the conveying directions of the differential speed conveyor 100 and the product synchronous conveyor belt 400; the differential speed conveyor 100 includes at least two conveyor belts in the same direction but with different conveying speeds, and the baffle synchronous belt 200 receives materials from the differential speed conveyor 100. It also includes a baffle pusher 300 connected in conjunction with the baffle timing belt 200. The baffle pusher 300 is used to push the material carried by the baffle timing belt 200 to the product timing conveyor belt 400. The product timing conveyor belt 400 is used to receive the material from the baffle timing belt 200 and transport it to the gripping position material handling device 500. The transfer robot 700 is set on the side of the gripping position material handling device 500 and is set in the feeding part of the subsequent vacuum stretch film packaging device. It is used to transfer and transport the long cylindrical material that has been handled in the gripping position material handling device 500 to the vacuum stretch film packaging device. Specifically, the aforementioned differential speed conveying device 100 consists of a stainless steel frame and two independently driven baffle conveyor belts mounted on the stainless steel frame. The first baffle conveyor belt has a slower conveying speed, while the second baffle conveyor belt, which works in conjunction with the baffle synchronous belt 200, has a faster conveying speed. This causes the elongated cylindrical material on the second baffle conveyor belt to be spaced further apart from the elongated cylindrical material on the first baffle conveyor belt in the axial direction. Furthermore, the high speed of the second baffle conveyor belt allows the elongated cylindrical material on it to be propelled onto the baffle synchronous belt 200 under inertia, eliminating the need for a separate transfer mechanism.

[0038] The above structure enables automated feeding and conveying of elongated cylindrical materials (such as ham embryos), and simultaneously performs material handling operations on these materials during the automated feeding and conveying process. This allows the elongated cylindrical materials to be directly fed to the processing station of the vacuum stretch film packaging device. After feeding, no additional adjustments are required, facilitating the subsequent packaging of the elongated cylindrical materials by the vacuum stretch film packaging device. Compared with traditional manual feeding and material handling methods and existing feeding devices that can only achieve automatic feeding, this effectively improves production efficiency and quality. Furthermore, by reducing manual intervention, it also directly reduces the safety risks for relevant production personnel during equipment operation.

[0039] Furthermore, the differential speed conveyor 100, the baffle synchronous belt 200, and the product synchronous conveyor belt 400 in the above solution have a simple and convenient cooperative structure, and their arrangement is flexible and easy to adapt to actual installation space limitations, which helps to improve the adaptability and versatility of the feeding device in this application. For example, in one example, continuing to refer to Figure 1 As shown, the conveying direction of the differential speed conveyor 100 is the same as that of the synchronous conveyor belt 400. The differential speed conveyor 100, the baffle synchronous belt 200, and the synchronous conveyor belt 400 are arranged in a straight line. This arrangement is suitable for long and narrow installation environments or installation environments with sufficient omnidirectional installation space. In another example, the differential speed conveyor 100 is arranged parallel to one side of the synchronous conveyor belt 400, and their conveying directions are opposite. Compared with the straight arrangement in the previous example, this arrangement can effectively reduce the installation space occupied in the length direction and can adapt to installation environments with limited installation space in the length direction.

[0040] It should be noted that the arrangement of the differential speed conveyor 100, the baffle synchronous belt 200 and the product synchronous conveyor belt 400 in this application is not limited to the above example. The above example is only a preferred example of this application, and other different arrangements can also be adopted. This application does not make specific limitations on this.

[0041] Furthermore, referring to Figure 1As shown, along the conveying direction of the baffle synchronous belt 200, the baffle synchronous belt 200 has multiple spaced material carrying positions. The center distance between the material carrying positions is consistent with the center distance of the products placed in the vacuum stretch film packaging device, thereby realizing the first material sorting in the radial direction. When the number of products in adjacent baffles cannot meet the required number of rows or columns of the vacuum stretch film machine, or when there are abnormal situations, the unqualified materials will be discharged to the collection bucket at the end of the baffle synchronous belt 200. The product synchronous conveyor belt 400 has multiple parallel conveying channels, and the conveying channels are set one-to-one with the material carrying positions. Specifically, the product synchronous conveyor belt 400 adopts a baffle conveyor belt, which is equipped with multiple parallel baffles, and the aforementioned conveying channels are formed between adjacent baffles. By combining the baffle synchronous belt 200 and the product synchronous conveyor belt 400, multiple long cylindrical materials can be radially separated during the conveying process. This ensures that the long cylindrical materials meet the material placement requirements of the vacuum stretch film packaging device during the conveying process, facilitating direct feeding. Furthermore, the baffle synchronous belt 200 in the above scheme can directly utilize the intervals on the baffle synchronous belt 200 as material bearing positions to achieve radial separation of multiple materials. Moreover, the baffle synchronous belt 200 and the product synchronous conveyor belt 400 have simple structures, are easy to match and adjust, and the specifications and matching methods of the baffle synchronous belt 200 and the product synchronous conveyor belt 400 can be flexibly adjusted according to the feeding requirements of different specifications of vacuum stretch film packaging devices.

[0042] As a preferred embodiment of this application, refer to Figure 1 As shown, the baffle pusher device 300 includes a pusher plate and a pusher plate drive device connected to the pusher plate. In one example, refer to... Figure 1 As shown, the baffle synchronous belt 200 and the baffle pushing device 300 are both mounted on the upper part of a stainless steel bracket, with the baffle pushing device 300 positioned above the baffle synchronous belt 200. The pusher drive device includes a pusher motor and synchronous belts that respectively cooperate with the pusher motor and the pusher. The pusher motor is located on one side of the upper part of the baffle conveyor support frame, and its output end is connected to a drive shaft with multiple drive wheels. Multiple driven wheels are correspondingly mounted on the other side of the baffle conveyor support frame. The synchronous belt is fitted onto the corresponding drive wheels and driven wheels. The synchronous belt and the pusher are arranged in a one-to-one correspondence, and the pusher and the material carrying position are arranged in a one-to-one correspondence. By setting up the pusher drive device, the automatic pushing of the pushing device is achieved, which helps to improve the material transfer efficiency between the baffle synchronous belt 200 and the product synchronous conveyor belt 400, thereby improving the feeding efficiency.

[0043] Furthermore, referring to Figure 2 and Figure 3As shown, the gripping and material handling device 500 includes a support frame and a material handling platform disposed on the upper part of the support frame. The support frame includes a bracket 512, and the material handling platform is installed on the upper part of the bracket 512. The bottom of the bracket 512 is also provided with double-hole feet 511. By providing double-hole feet 511, the stability of the support frame can be improved, and the double-hole feet 511 and the bracket 512 can adopt a lifting connection structure to allow the support frame to adapt to changes in the terrain of the installation location. The material handling platform includes multiple conveying rollers 502 and roller drive devices connected to the conveying rollers 502. Multiple recesses are provided on the axial conveying rollers 502, and the recesses are arranged one-to-one with the conveying channels. In the final stage of material handling, the material handling platform uses conveyor rollers 502 for material transport instead of continuing with the product synchronous conveyor belt 400. This allows for secondary material handling in the radial direction through recesses on the conveyor rollers 502, ensuring the radial spacing between materials meets the loading requirements of the vacuum stretch film packaging device. Furthermore, the gaps between the conveyor rollers can be used to create blocking structures for axial material handling, thus adapting to the processing rhythm of the vacuum stretch film packaging device and further improving loading and processing efficiency. Additionally, the rigid conveyor structure of the conveyor rollers 502 provides ample support for the materials, facilitating their gripping in conjunction with the transfer robot 700.

[0044] In one example, refer to Figure 2 and Figure 3 As shown, the roller drive device includes a stepper motor 516, a transmission belt 510, and transmission pulleys 504 disposed at the ends of the conveyor rollers 502. Each transmission pulley 504 corresponds to a specific conveyor roller 502. The stepper motor 516 is connected to the conveyor roller 502 via the transmission belt 510 and the transmission pulleys 504. For details, please refer to... Figure 2 As shown, a transmission shaft 501 is provided at one end of the conveyor roller shaft 502. The aforementioned transmission pulley 504 is a double pulley provided on the transmission shaft 501, that is, two transmission belts 510 are provided on one pulley. The transmission pulleys 504 of two adjacent conveyor roller shafts 502 are connected by the same transmission belt 510. Preferably, referring to... Figure 2As shown, three conveyor rollers 502 form a group and are synchronously driven by two transmission belts 510. Each group of conveyor rollers 502 corresponds to a stepper motor 516. The bracket 512 is also provided with a motor mounting position. The stepper motor 516 is fixed in the motor mounting position by screws and is driven by the synchronous pulley 517 and the synchronous belt 518 to the double pulley on the conveyor roller 502 at the end of the corresponding group. Specifically, the synchronous pulley 517 is assembled with the stepper motor 516 by set screws and keys. The material handling platform also includes conveying mounting plates 505, conveying side plates 506, and conveying side plate covers 507 disposed at both ends of the conveying roller shaft 502. The two ends of the conveying roller shaft 502 are rotatably engaged with the conveying side plates 506 and the conveying side plate covers 507 via deep groove ball bearings 503. Specifically, the two conveying mounting plates 505 are fixed to both sides of the bracket 512 by screws, and the two conveying side plates 506 are fixed to the two conveying mounting plates 505 by screws. The drive shaft 501 is fitted with its corresponding conveying roller shaft 502 and then fixed by set screws. The deep groove ball bearings 503 are assembled with their corresponding conveying roller shaft 502 roller shaft fittings. The drive shaft 501 has a step to prevent the bearing from shifting. The conveying side plates 506 on both sides are provided with bearing placement holes, and the bearing placement holes are all stepped to prevent the deep groove ball bearings 503 from shifting. The conveying side plate covers 507 are fastened to the conveying side plates 506 to further prevent the deep groove ball bearings 503 from shifting. The bracket 512 is also equipped with a motor cover 519 for protecting the stepper motor 516. The motor cover 519 is connected and fixed to the bracket 512 by screws.

[0045] The aforementioned stepper motor 516, transmission belt 510, transmission pulley 504, and conveyor roller shaft 502 have a simple and mature cooperative structure and reliable transmission. They are highly maintainable and have low maintenance costs in actual use. Furthermore, the stepper motor 516 has the advantages of being responsive and easy to control. The conveying rhythm of the conveyor roller shaft 502 can be adjusted by adjusting the start and stop rhythm of the stepper motor 516 to further adapt to the processing rhythm of the vacuum stretch film packaging device.

[0046] Continue to refer to Figure 3As shown, the gripping and feeding device 500 also includes a blocking mechanism, and the bracket 512 has a mounting part located below the feeding platform, where the blocking mechanism is mounted. Integrating the blocking structure with the feeding platform on the support frame fully utilizes the mounting space on the support frame and shortens the stroke of the blocking component during blocking operations, thus improving the blocking response speed. The blocking mechanism includes a blocking component and a blocking drive mechanism connected to the blocking component. A blocking gap exists between two adjacent conveyor rollers 502, allowing the blocking component to pass through. Driven by the blocking drive mechanism, the blocking component rises and falls vertically, with at least a portion of the blocking component able to pass through the blocking gap and rise above the feeding platform. Through the cooperation between the blocking mechanism and the conveyor rollers 502, axial feeding of long cylindrical materials can be achieved during conveying, adapting to the feeding rhythm of the vacuum stretch film packaging device. Furthermore, the above-mentioned blocking mechanism has a simple structure, is easy to use, and has low operating and maintenance costs. Specifically, the blocking component includes a baffle mounting plate 514 and a baffle 515 disposed on the baffle mounting plate 514. The blocking drive mechanism is a three-axis cylinder 513 disposed on the bracket 512. The three-axis cylinder 513 is fixedly connected to the bracket 512 by screws. The piston rod of the three-axis cylinder 513 is connected and cooperated with the baffle mounting plate 514 by screws, driving the baffle mounting plate 514 and driving the baffle 515 to pass through the blocking gap to block the material handling.

[0047] Furthermore, the gripping and feeding device 500 also includes a material detection component, which comprises multiple photoelectric sensors 509. These sensors 509 are positioned on both sides of the feeding platform to monitor the presence and quantity of material on the platform. For more details, please refer to... Figure 2 As shown, multiple photoelectric brackets 508 are also provided on the conveyor side plate cover 507, and multiple photoelectric detection elements 509 are correspondingly connected to the multiple photoelectric brackets 508. By setting up material detection components, it is convenient to realize automated feeding and sorting, and also to enable relevant production personnel to monitor the operation of the feeding device in this application in real time, so as to ensure the safe operation of the equipment.

[0048] In a preferred embodiment of this application, the end effector of the transfer robot 700 is equipped with a suction cup gripper 600, which includes a mounting plate and multiple suction cups mounted on the mounting plate. The use of suction cup grippers 600 instead of traditional mechanical grippers in the transfer robot 700 helps avoid damage to the material surface during material handling and better adapts to the requirements of food material handling and transfer. Preferably, the mounting plate is equipped with gripping detection elements corresponding to each suction cup, which are used to monitor whether the suction cups are holding material. By setting up gripping detection elements, relevant production personnel can monitor the operation of the transfer robot 700 in real time, ensuring feeding efficiency and equipment operation safety.

[0049] In a practical application example, after the front-end pusher elevator organizes the long cylindrical materials into a single row, the differential speed impact conveyor 100 separates the row of long cylindrical materials and sequentially impacts them into the material-bearing positions on the baffle synchronous belt 200. The height of the baffle synchronous belt 200 is slightly lower than that of the differential speed impact conveyor 100 to prevent the long cylindrical materials from hitting the stainless steel frame baffle and bouncing back, thus interfering with subsequent impacts. The photoelectric detection device at the impact position detects the presence or absence of material to determine whether the baffle synchronous belt 200 needs to be activated. Each time a long cylindrical material is impacted into the baffle synchronous belt 200, the baffle synchronous belt 200 advances one position. When the quantity of elongated cylindrical material meets the requirements of the baffle pusher 300, the host computer determines whether the quantity of elongated cylindrical material meets the quantity requirements of the vacuum stretch film packaging device. If it does, it sends an action signal to the baffle pusher 300. If it does not meet the requirements (usually the quantity is less than the requirements of the vacuum stretch film packaging device) and there are empty spaces in the middle, the empty material at the front end will be directly conveyed out and fall into the collection box. The baffle pusher 300 pushes the material to the product synchronous conveyor belt 400, which conveys a row of elongated cylindrical material to the gripping and sorting device 500. When the gripping and sorting device 500 receives the first row of material, the baffle 515 of the blocking mechanism will descend, allowing the elongated cylindrical material to run to the end of the sorting platform. When the end of the sorting platform is full, the baffle 515 rises to stop the second row of material, and the distance between the two sets of baffles 515 is equal to the center distance of the elongated cylindrical material in the vacuum stretch film packaging device. Before the transfer robot 700 grabs the long cylindrical material, the photoelectric detection component 509 on the bracket 512 detects whether there are long cylindrical materials on the material handling platform that meet the quantity requirements of the vacuum stretch film packaging device. When the grabbing conditions are met, the transfer robot 700, carrying the suction cup gripper 600, grabs eight long cylindrical materials at the same time. After grabbing, the eight grabbing detection components detect whether the material is dropped during the movement of the suction cup. If no material is dropped, it is placed in the vacuum stretch film packaging device. If more than two pieces are dropped, the baffle 515 descends to allow the long cylindrical materials that have fallen to the end of the material handling platform to flow to the collection box.
