Description

Technical Field

[0001] This utility model relates to the field of sheet material loading and unloading technology, specifically to a limiting mechanism for sheet material loading and unloading equipment. Background Technology

[0002] Sheet materials are a common type of material, widely used in various fields, most commonly as a support. For example, in the biological field, a porous sheet material with a bottom diameter larger than the top diameter and a step in the middle is used as a support. For sheet materials that need to be reused, they are collected and cleaned, and loading and unloading devices are usually used to assist in the process.

[0003] Currently, a utility model patent with announcement number CN217376431U discloses a magazine-type automatic loading and unloading device for sheet metal, including a discharge mechanism. The discharge mechanism includes a base, a hopper, a sliding plate, and a first driving device. The hopper is set on the base, and the sliding plate is set inside the base and located below the hopper. The first driving device is connected to the sliding plate and is used to drive the sliding plate to move within the base. When sheet metal is placed in the hopper, the sheet metal at the bottom of the hopper falls into the temporary storage area on the sliding plate. When the pushing part pushes the sheet metal at the bottom of the hopper into the sheet metal temporary storage area, the stop part is located exactly below the hopper, which can limit the second to last sheet metal. By automatically discharging from the bottom of the hopper, the discharge height of the sheet metal can be kept consistent, eliminating the need for a height compensation mechanism.

[0004] In existing sheet metal loading and unloading equipment, most methods employ top or bottom discharge. In top discharge, the operating height of the sheet metal transfer equipment, such as suction cups, is limited, requiring height compensation to ensure proper positioning of the sheet metal. While bottom discharge, as described above, does not require height compensation, friction occurs between the bottom second sheet metal and the stop after the first sheet metal is removed, leading to wear over time. This application addresses these issues by providing a limiting mechanism for sheet metal loading and unloading equipment. Utility Model Content

[0005] Based on the above description, this utility model provides a limiting mechanism for a sheet metal loading and unloading device to solve the problem that wear easily occurs between the sheet metal and the structure during the operation of the existing bottom-discharge sheet metal loading and unloading device.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A limiting mechanism for a plate loading and unloading equipment includes a support shell, two storage bins and a linear motion module are provided inside the support shell, a loading plate is provided on the linear motion module, and a perforated plate with a convex cross-section is placed in the storage bin. The storage bin is equipped with a limiting component on its outer side, and the support shell is equipped with two lifting components to lift the perforated plate, as well as two transmission components to drive the corresponding limiting components to cancel the limiting. The limiting component includes two outer shells located on the outside of the corresponding storage bins and symmetrically distributed front and back. Each of the two symmetrical outer shells is rotatably connected to a limiting component on one side. The top of the limiting component abuts against the bottom of the perforated plate, and an elastic component is provided between the limiting component and the corresponding outer shell. The transmission assembly includes a counter-movement module, which has two pushers capable of counter-movement, and the two pushers respectively abut against the outer sides of two limiting members.

[0007] The above technical solution can limit the perforated plate placed in the storage bin by the limiting component, and drive the pushing component to move in opposite directions by the opposing motion module, so as to push the limiting component away from the perforated plate and thus achieve the effect of canceling the limiting.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, each of the two symmetrical outer shells has a movable groove on its opposite side, with an open bottom. The limiting member includes a movable plate that is rotatably connected to the movable groove via a rotating shaft. The top of the movable plate is provided with a limiting strip, which abuts against the bottom of the perforated plate. The outer side of the limiting strip is arc-shaped. The bottom of the movable plate is provided with a push plate. Two mounting slots are opened on the opposite sides of the two symmetrical movable plates. The elastic element includes a compression spring provided in the mounting slot. The side of the compression spring away from the movable plate is connected to the movable slot.

[0010] The above technical solution enables the limiting strip to effectively physically limit the bottom of the perforated plate.

[0011] Furthermore, the opposing motion module includes a fixed plate disposed within the support shell, a photoelectric sensing module disposed on the fixed plate, a servo motor disposed at the bottom of the fixed plate, the output shaft of the servo motor passing through the bottom of the fixed plate and fitted with a gear, and the output shaft of the servo motor being rotatably connected to the bottom of the fixed plate through a bearing. The gear has two racks meshing on its outer side. The two racks are centrally symmetrical about the gear. The bottom of the racks is equipped with a sliding plate. The top of the sliding plate near the photoelectric sensing module is equipped with a light-blocking plate. The top of the fixed plate is equipped with two slide rails for sliding on the corresponding two sliding plates.

[0012] The above technical solution enables the gear to drive the two racks to move in opposite directions, thereby allowing the slide to move on the outside of the corresponding rail.

[0013] Furthermore, the fixing plate is provided with two mounting seats, each with a through hole on one side and a laying groove on the other side; The layout groove is connected to the interior of the corresponding through hole, and the top of the layout groove is open.

[0014] The above technical solutions enable the mounting base to meet the structural layout requirements.

[0015] Furthermore, the pushing component includes a transmission plate hinged to the layout groove by a pin, and two connecting pieces are provided at the bottom of the transmission plate, with an inner rod provided between the two connecting pieces on opposite sides. The slide plate has an extension plate on the side away from the gear, and a circular hole is provided on the extension plate for the inner rod to pass through and be placed, the diameter of the inner rod being smaller than the inner diameter of the circular hole.

[0016] Through the above technical solution, the transmission plate hinged by the pin can rotate around the pin; and under the push of the extension plate, the connecting piece can be moved through the inner rod.

[0017] Furthermore, the two fixed plates are located in the same vertical plane as the two storage bins, and the opposite sides of the two transmission plates located in the same vertical plane are respectively attached to the opposite sides of the two corresponding push plates.

[0018] The above technical solution enables the transmission plate to apply pressure to the push plate normally.

[0019] Furthermore, a support plate is provided inside the support shell, the storage bin is located above the support plate, and the linear motion module is disposed on the support plate; The support plate has a connecting hole for the movement of the transmission plate.

[0020] The above technical solution enables the linear motion module to move the cargo tray below the storage bin.

[0021] Furthermore, the lifting assembly includes a hydraulic cylinder disposed within the support housing, the piston end of the hydraulic cylinder being provided with a connecting frame, and four lifting rods being provided on the connecting frame.

[0022] The above technical solution allows for support of the bottom of the perforated plate using a lifting rod.

[0023] Furthermore, the support plate has a lifting hole through which the lifting rod passes, and the lifting rod is located on the outside of the linear motion module and the loading tray.

[0024] The above technical solution enables the lifting rod to move normally through the corresponding lifting hole.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. The limiting component can limit the perforated plate waiting to be discharged in the storage bin, preventing it from rubbing against the linear movement module and the loading tray, thus greatly avoiding structural wear and meeting the requirements of long-term stable use; the lifting component can lift the bottom of the perforated plate, and can replace the limiting component to support the perforated plate after the limiting component is removed. The lifting component can also lift the perforated plate to be placed smoothly on the loading tray, avoiding damage caused by vertical drop; 2. The transmission component can drive the limit component to open and close, and the elastic compensation function can enable the limit bar to move normally to the bottom of the perforated plate and limit it. With the cooperation of the linear motion module and the loading plate, the perforated plate that is lowered by the lifting component can be placed normally on the loading plate, and then the linear motion module can be used for linear movement and conveying to complete the unloading work.

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] Example: Reference Figure 1 and Figure 2 A limiting mechanism for a sheet metal loading and unloading device includes a support shell 1, which contains two storage bins 2 and a linear motion module 7. The linear motion module 7 has a loading tray 8. The storage bins 2 contain perforated sheet metal 4 with a convex cross-section. Limiting components 3 are provided on the outside of the storage bins 2. The support shell 1 contains two lifting components 5 to lift the perforated sheet metal 4, and two transmission components 6 to drive the corresponding limiting components 3 to cancel the limiting. The limiting components 3 include two outer shells 31 located on the outside of the corresponding storage bins 2 and symmetrically distributed front and back. Each of the two symmetrical outer shells 31 has a limiting member rotatably connected to one side of its opposite side. The top of the limiting member abuts against the bottom of the perforated sheet metal 4, and an elastic member is provided between the limiting member and the corresponding outer shell 31. The transmission components 6 include a counter-movement module, which has two pushing members capable of counter-movement. The two pushing members abut against the outside of the two limiting members respectively.

[0031] It should be noted that the perforated plate 4 is composed of two rectangular plates, with the area of ​​the bottom rectangular plate being larger than that of the top rectangular plate, so that the cross-section of the perforated plate 4 can form a trapezoid; thus, the top of the limiting member can pass through the top outer side of the bottom first perforated plate 4 and abut against the bottom of the bottom second perforated plate 4, allowing the bottom first perforated plate 4 to be loaded and unloaded normally.

[0032] refer to Figure 5 and Figure 6Each of the two symmetrical outer shells 31 has a movable groove 32 on one side. The bottom of the movable groove 32 is open. The limiting component includes a movable plate 33 that is rotatably connected to the movable groove 32 via a rotating shaft. The top of the movable plate 33 is provided with a limiting strip 34. The limiting strip 34 abuts against the bottom of the perforated plate 4. The outer side of the limiting strip 34 is arc-shaped, so that the limiting strip 34 can normally play a physical limiting role on the bottom of the perforated plate 4.

[0033] refer to Figure 6 and Figure 7 The bottom of the movable plate 33 is provided with a push plate 35. Two mounting slots 36 are opened on the opposite side of the two symmetrical movable plates 33. The elastic element includes a compression spring 37 in the mounting slot 36. The side of the compression spring 37 away from the movable plate 33 is connected to the movable slot 32. The compression spring 37 can provide an initial force to the movable plate 33, so that the movable plate 33 can drive the limit bar 34 to move to the bottom of the perforated plate 4.

[0034] refer to Figure 4 and Figure 9 When in use, the limiting strip 34 is located at the bottom of the perforated plate 4, providing physical support and limiting effect; the moving plate 33 is driven to rotate by the opposing motion module driving pusher, so that the limiting strip 34 moves away from the perforated plate 4, and at the same time, the compression spring 37 is compressed, allowing the perforated plate 4 to fall normally.

[0035] refer to Figure 3 and Figure 8 The opposing motion module includes a fixed plate 61 located inside the support shell 1. A servo motor 63 is located at the bottom of the fixed plate 61. The output shaft of the servo motor 63 passes through the bottom of the fixed plate 61 and is fitted with a gear 64. The output shaft of the servo motor 63 is rotatably connected to the bottom of the fixed plate 61 through a bearing, so that the servo motor 63 can drive the gear 64 to rotate smoothly.

[0036] refer to Figure 8 The gear 64 has two racks 65 meshing on its outer side. The two racks 65 are centrally symmetrically distributed around the gear 64, allowing the gear 64 to drive the two racks 65 to move in opposite directions. The bottom of the racks 65 is equipped with a sliding plate 66, and the top of the fixed plate 61 is equipped with two slide rails 67 for the corresponding two sliding plates 66 to slide, allowing the sliding plates 66 to move outside the corresponding slide rails 67. The fixed plate 61 is equipped with a photoelectric sensing module 62, which can be a photoelectric sensor and a reflector. The top of the sliding plate 66 near the photoelectric sensing module 62 is equipped with a light-blocking plate. The light-blocking plate is C-shaped, and the outer side is equipped with a baffle located between the photoelectric sensor and the reflector on opposite sides. By blocking the light source of the photoelectric sensor through the baffle, the sensing effect can be achieved, thereby enabling precise positioning of the displacement of the sliding plate 66 and making the transmission more accurate.

[0037] refer to Figure 8 The fixing plate 61 is provided with two mounting seats 68. Each mounting seat 68 has a through hole 681 on one side and a layout groove 682 on the other side. The layout groove 682 is connected to the interior of the corresponding through hole 681. The top of the layout groove 682 is open, so that the mounting seat 68 can meet the structural layout requirements.

[0038] refer to Figure 8 The pushing component includes a transmission plate 69 hinged to the mounting groove 682 via a pin. The transmission plate 69, hinged via a pin, can rotate around the pin. The bottom of the transmission plate 69 is provided with two connecting pieces 691. An inner rod is provided between the opposite sides of the two connecting pieces 691. An extension plate is provided on the side of the slide plate 66 away from the gear 64. A circular hole is opened on the extension plate for the inner rod to pass through. The diameter of the inner rod is smaller than the inner diameter of the circular hole. Since the movement trajectory of the connecting pieces 691 is arc-shaped when the transmission plate 69 rotates via the pin, the extension plate can normally push the inner rod to move through the circular hole with the diameter difference and the inner rod, without hindering the normal rotation of the transmission plate 69. Thus, under the push of the extension plate, the connecting pieces 691 can be moved through the inner rod.

[0039] refer to Figure 3 The two fixed plates 61 are located in the same vertical plane as the two storage bins 2. The opposite sides of the two transmission plates 69 located in the same vertical plane are respectively attached to the opposite sides of the two corresponding push plates 35, so that the transmission plates 69 can normally apply pressure to the push plates 35.

[0040] It should be noted that when the limiting strip 34 is in the state of limiting the bottom of the perforated plate 4, the inner rod abuts against the inner wall of the round hole, so that the inner rod can physically limit the transmission plate 69 through the round hole, and then limit the push plate 35 through the transmission plate 69, so that the limiting strip 34 can stably support the bottom of the perforated plate 4.

[0041] In use, the servo motor 63 drives the gear 64 to rotate, causing the two corresponding racks 65 to move in opposite directions. This, in turn, drives the extension plate to move via the slide plate 66. The inner rod can be pushed to move through the inner wall of the round hole, allowing the transmission plate 69 to rotate around the pin. During the rotation, the corresponding push plate 35 can be pushed to move, thereby causing the movable plate 33 to rotate and the limit strip 34 to move away from the perforated plate 4.

[0042] refer to Figure 3The support shell 1 is provided with a support plate 11, the storage bin 2 is located above the support plate 11, and the linear motion module 7 is provided on the support plate 11, so that the linear motion module 7 can drive the loading plate 8 to move below the storage bin 2. The support plate 11 is provided with a connecting hole for the transmission plate 69 to move, so that the transmission plate 69 can move normally.

[0043] It should be noted that the linear motion module 7 can be a lead screw motion module or a synchronous belt motion module, which can achieve the requirement of smooth linear motion and is a commonly used standardized equipment in modern industry, so it will not be elaborated further.

[0044] refer to Figure 3 The lifting assembly 5 includes a hydraulic cylinder 51 located inside the support shell 1. The piston end of the hydraulic cylinder 51 is provided with a connecting frame 52, and the connecting frame 52 is provided with four lifting rods 53. The bottom of the perforated plate 4 can be supported by the lifting rods 53.

[0045] refer to Figure 3 The support plate 11 has a lifting hole through which the lifting rod 53 passes. The lifting rod 53 is located on the outside of the linear movement module 7 and the loading plate 8, so that the lifting rod 53 can move normally through the corresponding lifting hole.

[0046] In use, the linear motion module 7 drives the loading tray 8 to move between the bottoms of the two storage bins 2. The hydraulic cylinder 51 pushes the lifting rod 53 upward through the connecting frame 52, so that its top end abuts against the bottom of the perforated plate 4. The driving limit bar 34 cancels the limit on the perforated plate 4, and the hydraulic cylinder 51 drives the lifting rod 53 downward. Under the action of gravity, the perforated plate 4 will move downward together. While the downward movement is in progress, the limit bar 34 can be directly driven back to its original position. Under the elastic compensation of the compression spring 37, the outer side of the limit bar 34 will first fit against the outer side of the first perforated plate 4 at the bottom. During the continued descent, the second perforated plate 4 at the bottom stops when it abuts against the top of the limit bar 34, thus completing the continued limit on the perforated plate 4 in the storage bin 2. The perforated plate 4 driven by the lifting rod 53 is then placed on the loading tray 8 and can be sent out by the linear motion module 7.

[0047] It should be noted that if feeding is required, after the loading tray 8 moves to the bottom of the storage bin 2, the perforated plate 4 is lifted by the lifting rod 53 and pushed to move the perforated plate 4 in the storage bin 2 upward. Due to the elasticity of the compression spring 37, the perforated plate 4 will push the limiting strip 34 to rotate and squeeze the compression spring 37 when it rises, so that the limiting strip 34 does not need to be released during the feeding process. Under the elastic rebound of the compression spring 37, after the perforated plate 4 is fed, it will automatically move to the bottom of the first perforated plate 4 at the bottom and continue to play the role of physical limiting.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
