Description

Technical Field

[0001] This utility model relates to the field of temporary storage technology for production lines, and in particular to a temporary storage structure for pillow bag production lines. Background Technology

[0002] In the production processes of industries such as food and daily necessities, pillow bags are a commonly used packaging form, and their assembly line production needs to achieve continuous and efficient operation. However, in actual production, downstream packaging and palletizing equipment often needs to be suspended due to malfunctions, maintenance, parameter adjustments, etc. If upstream feeding and filling equipment stops at the same time, it will lead to production interruption, waste of raw materials, and increase the time cost of restarting and debugging. Therefore, the temporary storage function of the pillow bag assembly line becomes the key to ensuring production continuity. For example, a Chinese patent proposes a temporary storage device for a packaging production line, patent publication number CN210884141U. When in use, the above patent uses the cooperation of a conveyor belt and a temporary storage rack to temporarily store the packaging, avoiding the accumulation of packaging when downstream equipment stops. However, the above patent only solves the basic problem of temporary storage of packaging, and does not realize the automated transfer and reset of the temporary storage process, nor does it consider the protection needs of pillow bags during the temporary storage process. The applicant discovered the following shortcomings when implementing the above plan: 1. The device is not equipped with a detection module and an auxiliary feeding structure, so it cannot accurately determine the position of the pillow bag, which may lead to pillow bag displacement or feeding problems, affecting the smoothness of the temporary storage process. 2. The device lacks cushioning protection and layered storage design for pillow bags during use. The pillow bags are easily deformed and damaged due to falling impacts and stacking compression. At the same time, the storage space utilization rate is low, and the stored pillow bags cannot be automatically returned to the production line, requiring manual intervention, thus reducing the practicality of the device.

[0003] Therefore, we propose a temporary storage structure for pillow bag production lines to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a temporary storage structure for a pillow bag production line, which solves the problems of upstream equipment needing to be shut down during downstream equipment maintenance, pillow bags being easily damaged during temporary storage, and low automation in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A temporary storage structure for a pillowcase production line includes a conveyor belt, a bracket fixedly mounted at the bottom end of the conveyor belt, and a set of baffles extending towards the middle of the conveyor belt fixedly mounted on both sides of the bracket. A drive motor is fixedly mounted on one side of the bracket, and the output shaft of the drive motor is fixedly connected to the conveyor belt. The structure also includes: The support is fixedly installed with a feeding box on the side away from the drive motor. The top of the feeding box has an opening facing the conveyor belt of the production line, and multiple sets of ventilation holes are opened on the top of the feeding box. A protective component is installed on the top inside the feeding box. A temporary storage box is fixedly installed on the side of the bracket near the unloading box. The top of the temporary storage box also has an opening facing the conveyor belt of the production line, and a temporary storage component is installed inside the temporary storage box. Preferably, the detection module is fixedly installed on the side of the bracket away from the feeding box, and the detection module faces the side of the conveyor belt of the production line. Preferably, the baffle is fixedly installed with an air jet at the opening of the feeding box, and the air jet is connected to an external air supply device. Preferably, the protective component includes a protective plate and springs. The protective plate is hinged to the inside of the feeding box near the opening, and the surface of the protective plate is provided with multiple sets of ventilation holes. Two sets of springs are fixedly installed on the protective plate away from the opening of the feeding box, and both sets of springs are fixedly connected to the top of the inside of the feeding box. Preferably, the temporary storage component includes a fixed rod, a rotating rod, and a placement block. Multiple sets of parallel fixed rods are fixedly installed on both sides inside the temporary storage box. The same number of rotating rods are rotatably installed between the multiple sets of fixed rods inside the temporary storage box. Two sets of placement blocks are fixedly installed in the middle of the rotating rod. The placement blocks are in the shape of an inverted trapezoid, and the opposite sides of the two sets of placement blocks are attached to the fixed rod. Preferably, the feeding box and the temporary storage box are fitted together, and the bottom end of the feeding box and the temporary storage box where they are fitted together is provided with a communicating slot. A first pneumatic push rod is fixedly installed on the side of the feeding box away from the temporary storage box, and the output rod of the first pneumatic push rod faces the side of the temporary storage box and is fixedly installed with a push plate.

A third pneumatic push rod is fixedly installed on one side of the top end of the temporary storage box, and the output rod of the third pneumatic push rod faces the side of the conveyor belt of the production line and is also fixedly installed with a push plate.

[0006] This utility model has at least the following beneficial effects: The detection module monitors the status of the pillow bags in real time, and with the help of the air jet nozzle to assist in feeding, and with the orderly linkage of multiple sets of pneumatic push rods, the entire process of feeding, temporarily storing, transferring and resetting the pillow bags is completed without human intervention, which greatly reduces the input of manpower. When the downstream equipment is under maintenance, the upstream does not need to stop. The pillow bags can be temporarily stored through the device, and can be quickly returned to the production line after the downstream is restored, which effectively avoids production interruption and ensures the stability of the overall process.

[0007] This utility model also has the following beneficial effects: The protective components inside the feeding box cushion the impact of the falling pillow bags with protective plates and springs, while the ventilation hole design maintains internal ventilation to prevent the pillow bags from getting damp or damaged by impact. The temporary storage components form a multi-layered stable space, enabling the pillow bags to be stored in an orderly manner in layers. This not only prevents stacking, squeezing and deformation, but also makes full use of the internal space of the temporary storage box, significantly increasing the temporary storage capacity per unit space.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] Reference Figure 1-6 A temporary storage structure for a pillowcase production line includes a conveyor belt 1, a bracket 2 fixedly installed at the bottom end of the conveyor belt 1, and a set of baffles 3 extending towards the middle of the conveyor belt 1 fixedly installed on both sides of the bracket 2. A drive motor 4 is fixedly installed on one side of the bracket 2, and the output shaft of the drive motor 4 is fixedly connected to the conveyor belt 1. The structure also includes: A feeding box 7 is fixedly installed on the side of the bracket 2 away from the drive motor 4. The top of the feeding box 7 has an opening facing the conveyor belt 1 of the production line, and multiple sets of ventilation holes are opened on the top of the feeding box 7. A protective component is installed on the top inside the feeding box 7. A temporary storage box 8 is fixedly installed on the side of the bracket 2 near the unloading box 7. The top of the temporary storage box 8 also has an opening on the side facing the conveyor belt 1 of the production line, and a temporary storage component is installed inside the temporary storage box 8. Furthermore, a detection module 6 is fixedly installed on the side of the bracket 2 away from the unloading box 7, and the detection module 6 faces the side of the conveyor belt 1. By setting the detection module 6 on the side of the bracket 2 away from the unloading box 7, the detection module 6 is a mature existing technology and will not be described in detail here. The detection module 6 faces the conveyor belt 1, which can detect the pillow bags on the conveyor belt 1 in real time, and promptly detect the positional deviation, quantity abnormality and other situations of the pillow bags. This provides accurate signal support for subsequent unloading, temporary storage and other processes, and ensures the accuracy and stability of the entire temporary storage process of the production line. Furthermore, a jet nozzle 5 is fixedly installed at the opening of the baffle 3 corresponding to the feeding box 7, and the jet nozzle 5 is connected to an external air supply device. When the detection module 6 detects that the pillow bag has reached the feeding position, the jet nozzle 5 can quickly spray air to assist the pillow bag to smoothly enter the feeding box 7 from the conveyor belt 1 of the production line, avoiding the pillow bag from being stuck on the conveyor belt due to friction or position deviation, thus improving feeding efficiency. At the same time, the airflow force is gentle and will not cause compression damage to the pillow bag. Furthermore, the protective assembly includes a protective plate 9 and springs 10. The protective plate 9 is hinged to the inside of the feeding box 7 near the opening, and multiple sets of ventilation holes are provided on the surface of the protective plate 9. Two sets of springs 10 are fixedly installed on the protective plate 9 away from the opening of the feeding box 7, and both sets of springs 10 are fixedly connected to the top of the inside of the feeding box 7. The protective plate 9 hinged to the inside of the feeding box 7 near the opening, together with the two sets of springs 10 fixed away from the opening, can, on the one hand, buffer the pillow bag entering the feeding box 7. The elastic deformation of the springs 10 absorbs the impact force of the falling pillow bag and prevents the pillow bag from being damaged by impact. On the other hand, the multiple sets of ventilation holes on the surface of the protective plate 9 cooperate with the ventilation holes at the top of the feeding box 7 to ensure air circulation inside the feeding box 7 and avoid problems such as dampness and stuffiness of the pillow bag due to the sealed environment. Moreover, the hinged design of the protective plate 9 does not affect the normal falling of the pillow bag. Furthermore, the temporary storage component includes fixed rods 14, rotating rods 15, and placement blocks 16. Multiple sets of parallel fixed rods 14 are fixedly installed on both sides of the interior of the temporary storage box 8. An equal number of rotating rods 15 are rotatably installed between the corresponding sets of fixed rods 14 inside the temporary storage box 8. Two sets of placement blocks 16 are fixedly installed in the middle of the rotating rods 15. The placement blocks 16 are in the shape of an inverted trapezoid, and the opposite sides of the two sets of placement blocks 16 are attached to the fixed rods 14. The multiple sets of parallel fixed rods 14 on both sides of the interior of the temporary storage box 8, the rotating rods 15 rotatably installed between the corresponding fixed rods 14, and the two sets of inverted trapezoidal placement blocks 16 in the middle cooperate to form a multi-layered stable temporary storage space. This allows for layered storage of pillowcases, preventing deformation caused by stacking and squeezing. Simultaneously, the rotating rods 15... It can rotate flexibly as the pillow bag is put in and taken out, reducing friction between the pillow bag and the temporary storage components, further protecting the appearance and structural integrity of the pillow bag, and the multi-layer design can improve the space utilization of the temporary storage box 8.

[0013] Furthermore, the feeding box 7 and the temporary storage box 8 are fitted together, and the bottom of the feeding box 7 and the temporary storage box 8 where they are fitted together is provided with a communicating slot. A first pneumatic push rod 11 is fixedly installed on the side of the feeding box 7 away from the temporary storage box 8, and the output rod of the first pneumatic push rod 11 faces the side of the temporary storage box 8 and is fixedly installed with a push plate. A second pneumatic push rod 12 is fixedly installed in the middle of the bottom of the temporary storage box 8, and the output rod of the second pneumatic push rod 12 faces upward and is also fixedly installed with a push plate. A third pneumatic push rod 13 is fixedly installed on one side of the top of the temporary storage box 8, and the output rod of the third pneumatic push rod 13 faces the side of the conveyor belt 1 and is also fixedly installed with a push plate. The feeding box 7 and the temporary storage box 8 are fitted together, and the fitting area is provided with a slot, which cooperates with the first pneumatic push rod 11 on the side of the feeding box 7 and the second pneumatic push rod 12 at the bottom of the temporary storage box 8. The third pneumatic pusher 13 on one side of the top forms an automated material transfer and reset mechanism: the first pneumatic pusher 11 can smoothly push the pillow bag in the feeding box 7 into the temporary storage box 8 through the slot; the second pneumatic pusher 12 can push the temporarily stored pillow bag to adjust its position up and down, making it convenient for layered storage or retrieval; the third pneumatic pusher 13 can push the pillow bag in the temporary storage box 8 back to the conveyor belt 1 of the production line. The whole process does not require manual intervention, realizing the automated operation of pillow bag temporary storage and transfer, and improving work efficiency; and the output rods of the three sets of pneumatic pushers are all fixed to the push plate, which increases the contact area with the pillow bag, makes the force more uniform, and avoids excessive local force that damages the pillow bag. In summary: First, the drive motor 4 starts, driving the conveyor belt 1 to operate, causing the pillow bag to be conveyed forward. During the conveying process, the detection module 6 on the side of the bracket 2 away from the unloading box 7 detects the pillow bags on the conveyor belt 1 in real time. When the pillow bag is detected to have reached the unloading position, the baffle 3 quickly sprays air from the air nozzle 5 (connected to an external air supply device) at the opening of the unloading box 7, assisting the pillow bag to smoothly enter the unloading box 7 from the conveyor belt 1, preventing the pillow bag from getting stuck on the conveyor belt due to friction or positional deviation. When the pillow bag enters the unloading box 7, it first contacts the protective plate 9 hinged inside the unloading box 7 near the opening. The protective plate 9, together with two sets of springs 10 fixed away from the opening side, absorbs the impact force of the falling pillow bag through the elastic deformation of the springs 10, preventing the pillow bag from being damaged by impact. At the same time, the multiple sets of ventilation holes on the surface of the protective plate 9 cooperate with the ventilation holes at the top of the unloading box 7 to ensure that the unloading box 7... Internal air circulation prevents the pillowcase from getting damp and stuffy, and the hinged design of the protective plate 9 does not affect the pillowcase's continued descent to the bottom of the feeding box 7. Then, the first pneumatic push rod 11 on the side of the feeding box 7 away from the temporary storage box 8 is activated. The output rod of the first pneumatic push rod 11 drives the push plate to push the pillowcase inside the feeding box 7, allowing the pillowcase to enter the temporary storage box 8 through the slot at the bottom end of the feeding box 7 where it meets the temporary storage box 8. After the pillowcase enters the temporary storage box 8, the second pneumatic push rod 12 at the bottom center of the temporary storage box 8 is activated. The output rod of the second pneumatic push rod 12 drives the push plate to adjust the pillowcase's position up and down, conveying the pillowcase to the corresponding layer of the temporary storage component. The temporary storage component includes multiple sets of parallel fixing rods 14 on both sides inside the temporary storage box 8, rotating rods 15 rotatably installed between the corresponding fixing rods 14, and two sets of inverted trapezoidal placement blocks 16 in the middle (on the side away from the fixing rods 14). The combination of the three pneumatic pushers (with the pneumatic pusher 15 and the pneumatic pusher 16) forms a multi-layered and stable temporary storage space, enabling layered storage of pillow bags and preventing them from being stacked, squeezed, or deformed. The rotating rod 15 can rotate flexibly as the pillow bags are placed in, reducing friction between the pillow bags and the temporary storage components and protecting the appearance and structural integrity of the pillow bags. At the same time, the multi-layered design improves the space utilization of the temporary storage box 8. When the downstream equipment is maintained and resumes operation, the third pneumatic pusher 13 on the top side of the temporary storage box 8 is activated. The output rod of the third pneumatic pusher 13 drives the push plate to push the pillow bags in the temporary storage box 8 back to the conveyor belt 1 of the production line, so that the pillow bags can continue to be transported to the downstream equipment. The entire process realizes the conveying, detection, unloading, buffering, temporary storage, and resetting of the pillow bags through the linkage of various devices, achieving the effect of not stopping the upstream equipment when the downstream equipment is maintained. In addition, the push plate design of the three sets of pneumatic pushers increases the contact area with the pillow bags, making the force more uniform and avoiding excessive local force that could damage the pillow bags.
