Description

A self-controlled guiding material handling device Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, specifically relating to a self-controlled guiding material handling device. Background Technology

[0002] In the automated packaging process of electric toothbrushes, both the toothbrush handle and the charger are placed in fixed locations. The handle or charger packaging box is placed in a fixed position, and then the product (toothbrush handle or charger) is fed into the corresponding packaging box along a fixed trajectory. In this packaging method, the packaging boxes cannot be continuously fed, resulting in low packaging efficiency. Moreover, it requires high positioning accuracy for the packaging box or product; any deviation in the position of the product and the packaging box can easily lead to material damage. Summary of the Invention

[0003] The purpose of this invention is to provide a self-controlled guiding material handling device that has a certain degree of fault tolerance during the boxing process, provides reliable guidance for products to be placed into the packaging box, and thus provides a structural basis for further improving the boxing cycle and efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a self-controlled guiding material handling device, including a longitudinal adjustment mechanism, two parallel guide rods are provided on the longitudinal adjustment mechanism, a plurality of mounting seats are provided on the guide rods, each mounting seat is connected to a first direction guiding component, and the first direction guiding components are arranged in pairs on the two guide rods;

[0005] The first directional guide assembly includes a fixed block, a guide plate clamping plate, a guide plate, a pin, an active telescopic mechanism, and a spring. The fixed block is connected to the mounting base. The middle part of the guide plate clamping plate is rotatably connected to the fixed block via the pin, and the guide plate is fixed to the end of the guide plate clamping plate. The active telescopic mechanism is disposed on the fixed block, and the spring is disposed between the fixed block and the guide plate clamping plate. The spring and the active telescopic mechanism are respectively located on both sides of the pin. The active telescopic mechanism is used to push the guide plate clamping plate to rotate around the pin, so that the guide plate opens outward. The spring is used to release elastic force when the active telescopic mechanism retracts, so that the guide plate clamping plate drives the guide plate to rotate inward and reset.

[0006] It also includes a lifting cylinder, whose piston head is connected to a suction cup assembly, which is equipped with a suction cup for picking up materials.

[0007] Furthermore, the mounting base includes a central connector and a base mounting plate. The central connector is disposed in the middle of the guide rod, and the base mounting plate is distributed on both sides of the positioning mounting base.

[0008] Furthermore, the middle connector is provided with an adapter clamp for clamping the two guide rods.

[0009] Furthermore, the base mounting plate is provided with a clamping adjustment seat that clamps onto the two guide rods.

[0010] Furthermore, the base mounting plate is provided with fixing rings on both sides, and the fixing rings are fixed on the guide rod to limit the sliding adjustment range of the base mounting plate along the guide rod.

[0011] Furthermore, the active telescopic mechanism is a needle cylinder.

[0012] Alternatively, each of the two guide rods is provided with an end connector for connecting the two guide rods. Each end connector is provided with a second direction guide component. The structure of the second direction guide component is the same as that of the first direction guide component. The opening and closing direction of the guide plates of the two second direction guide components is parallel to the guide rod of the longitudinal adjustment mechanism and perpendicular to the opening and closing direction of the guide plates of the pair of first direction guide components.

[0013] As another option, the longitudinal adjustment mechanism is provided in two parts and connected to the two relatively moving components of the lateral adjustment mechanism.

[0014] Furthermore, the lateral adjustment mechanism includes a fixed support plate, a pitch cylinder, a movable support plate, and a fixed frame; the telescopic end and the cylinder body of the pitch cylinder are respectively connected to the fixed support plate and the movable support plate to realize the movement of the movable support plate relative to the fixed support plate; the fixed support plate is connected to a longitudinal adjustment mechanism through two oppositely arranged fixed frames, and the movable support plate is connected to another longitudinal adjustment mechanism through two other oppositely arranged fixed frames.

[0015] Furthermore, the two opposing fixed frames are respectively fixedly connected to two guide rods of the same longitudinal adjustment mechanism, and the lifting cylinder is located between the two fixed frames, with the top of the lifting cylinder connected to a fixed support plate or a movable support plate.

[0016] The beneficial effects of this invention are as follows: This invention controls the opening and closing of the guide plate through a lever mechanism. When open, it is in the material-taking state; when closed, it is in the guiding and discharging state, which can improve the accuracy of automatic boxing. In this invention, after the guide plate is closed, a spring provides self-controlled floating guidance, offering a certain degree of fault tolerance. Even if the material is not precisely aligned with the packaging box, it will still enter the box due to the floating of the guide plate. Furthermore, this allows the packaging box transport line to always be in a feeding state, further improving boxing efficiency.

[0017] This invention allows for horizontal adjustment of the distance between the first direction guide components along the guide rod to accommodate the width of different products, preventing the small gap between the first direction guide components at both ends from affecting the absorption of products with a larger width.

[0018] This invention can connect two longitudinal adjustment mechanisms through a lateral adjustment mechanism, thereby simultaneously loading two packaging boxes and further improving loading efficiency. The lateral adjustment mechanism can adjust the distance between the two longitudinal adjustment mechanisms to accommodate the spacing between the two packaging boxes. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0035] Example 1

[0036] Referring to Figures 1-4, a self-controlled guiding material handling device includes a lateral adjustment mechanism 100, a longitudinal adjustment mechanism 200, a lifting cylinder 300, a first direction guiding component 400, a second direction guiding component 500, and a suction cup component 600.

[0037] The two relatively movable parts of the lateral adjustment mechanism 100 are each connected to a longitudinal adjustment mechanism 200 to achieve the packing of two packaging boxes. Each longitudinal adjustment mechanism 200 is equipped with a corresponding lifting cylinder 300. The cylinder body of the lifting cylinder 300 is connected to the lateral adjustment mechanism 100, and the piston head of the lifting cylinder 300 is connected to the suction cup assembly 600 below, which picks up the product to be packaged. The first directional guide assembly 400 and the second directional guide assembly 500 are both located below the longitudinal adjustment mechanism 200 to provide guidance for the packing of the product.

[0038] The lateral adjustment mechanism 100 includes a fixed support plate 101, a variable pitch cylinder 102, a movable support plate 103, a fixed frame 104, and a transition plate 105. The fixed support plate 101 is a rectangular plate, and the movable support plate 103 is an L-shaped plate. A clearance groove is provided on the lower surface of one end of the fixed support plate 101 to form a certain movable gap with the first surface of the movable support plate 103, facilitating relative movement of the movable support plate 103. The cylinder body of the variable pitch cylinder 102 is fixedly connected to the upper surface of the fixed support plate 101. The piston head of the variable pitch cylinder 102 is connected to the second surface of the movable support plate 103. The linear movement of the movable support plate 103 relative to the fixed support plate 101 is achieved by the extension and retraction of the variable pitch cylinder 102. The transition plate 105 is fixed to the lower surface of the fixed support plate 101, and the transition plate 105 and the movable support plate 103 are located at opposite ends of the fixed support plate 101. The lower surface of the transition plate 105 and the lower surface of the movable support plate 103 are each connected to a pair of fixing brackets 104. Each pair of fixing brackets 104 is connected to one of the longitudinal adjustment mechanisms 200, so that the lateral adjustment mechanism 100 can adjust the distance between the two longitudinal adjustment mechanisms 200 by extending and retracting the pitch cylinder 102, thereby adapting to the different widths of the two packaging boxes.

[0039] Furthermore, the lower surface of the fixed support plate 101 is fitted together with the transition plate 105 through a limiting groove for further fixation. The lower surfaces of the transition plate 105 and the movable support plate 101 are also fitted together with the top of the corresponding fixing frame 104 through limiting grooves for further fixation.

[0040] Furthermore, the thickness of the transition plate 105 is equal to the thickness of the first surface of the movable support plate 103, providing mounting surfaces of the same height for the two pairs of fixing brackets 104. In other embodiments, the transition plate 105 may be omitted, and instead, the thickness of the fixing support plate 101 at the position of the transition plate 105 may be increased so that it has a mounting surface of the same height as the movable support plate 103 at the other end.

[0041] The structure of the longitudinal adjustment mechanism is shown in Figures 7 and 8. It includes two parallel guide rods 201 arranged side by side. The two ends of the two guide rods 201 are connected by two end connectors 205, and the middle of the two guide rods 201 is connected to a central connector 204, thereby ensuring the parallelism and fixed spacing of the two guide rods 201. Each end of the end connector 205 has a C-shaped fixing hole, so that the guide rod 201 can pass through and be secured with screws to clamp the guide rod 201. The central connector 204 is C-shaped in the top view shown in Figure 8, and a transition clamp 204-1 is provided at the position where the guide rod 201 passes. The transition clamp 204-1 also has the aforementioned C-shaped fixing hole and clamps the guide rod 201 after the screws are tightened. Since the central connector 204 is C-shaped, the two transition clamps 204-1 on one side are an integral structure, and are arranged at intervals with the two transition clamps 204-1 on the other side, forming a C-shaped opening. Optionally, the two integrally formed adapter clamps 204-1 on the same side of the central connector 204 are fixed to one end of the two substrates 204-2 by screws, and the two adapter clamps 204-1 arranged at intervals on the other side of the central connector 204 are fixed to the other end of the two substrates 204-2, thereby forming a C-shaped structure.

[0042] The lower end of the fixing frame 104 is fixed to the middle of the guide rod 201 and is located between two adapter clamps 204-1 on the guide rod 201. Specifically, the lower end of the fixing frame 104 is provided with a C-shaped clamping head 104-1. The guide rod 201 passes through the clamping head 104-1 and is fastened with screws to prevent the fixing frame 104 from sliding on the guide rod 201.

[0043] Four fixing rings 202 are provided in the area between each end connector 205 and the middle connector 204 on the guide rod 201, that is, two fixing rings 202 are fixed in this area on each guide rod 201. The fixing rings 202 on the two guide rods 201 are positioned correspondingly, and an adjustment range is formed between adjacent fixing rings 202 in the same area on the guide rod 201. A base mounting plate 203 clamping the guide rod 201 is provided in the adjustment range. The base mounting plate 203 includes a base 203-2 and a clamping adjustment seat 203-1 for clamping the two guide rods 201, which is screwed onto the base 203-2. The clamping adjustment seat 203-1 also has a C-shaped fixing hole, which passes through the guide rod 201 and is clamped by screws. During use, the clamping adjustment seat 203-1 can be loosened as needed, and the base mounting plate 203 can be slid along the guide rod 201 to adjust the distance between adjacent fixing rings 202 on the same guide rod 201, so that the base mounting plate 203 can have a larger adjustment range.

[0044] The lower surfaces of the base mounting plate 203 and the lower surfaces of the central connector 204 are respectively connected to the first directional guide components 400. Thus, by sliding the base mounting plate 203, the distance between the first directional guide components 400 along the length of the guide rod 201 can be adjusted to accommodate the width of different products.

[0045] Furthermore, the end connectors 205 at both ends of the longitudinal adjustment mechanism 200 are also connected to second direction guide components 500, and the opening and closing directions of the two second direction guide components 500 are parallel to the guide rod 201 of the longitudinal adjustment mechanism 200.

[0046] The first directional guide component 400 and the second directional guide component 500 have the same structure. The structure and opening and closing principle of the first directional guide component 400 will be explained below.

[0047] As shown in Figures 5 and 6, the first directional guide assembly 400 includes a fixing block 401, a guide plate clamping plate 402, a guide plate 403, a pin 404, a needle-type cylinder 405, and a spring 406. The middle portion of the guide plate clamping plate 402 is rotatably connected to the fixing block 401 via the pin 404. The end of the guide plate clamping plate 402 extends out of the fixing block and is connected to the guide plate 403. The needle-type cylinder 405 is mounted on the fixing block 401. After the piston head of the needle-type cylinder 405 extends, it pushes the guide plate clamping plate 402 to rotate around the pin 404. The spring 406 is installed between the guide plate clamping plate 402 and the fixing block 401; for example, the spring 406 can be fixed to the guide plate clamping plate 402. Spring 406 and needle cylinder 405 are located on both sides of pin 404 to form a lever structure, so that when needle cylinder 405 retracts, the elastic force of spring 406 is released, which can push guide plate clamp 402 to rotate and reset. The fixing block 401 is fixed on the longitudinal adjustment mechanism 200, specifically, fixed to the end of the base mounting plate 203 or installed at the end of the middle connector 204.

[0048] The first directional guide components are arranged in pairs on the longitudinal adjustment mechanism 200, with each pair arranged opposite each other, so that when the needle cylinder 405 extends, the two guide plates 403 arranged opposite each other open outward, and the opening and closing direction of the guide plates 403 is perpendicular to the guide rod 201 of the longitudinal adjustment mechanism 200.

[0049] Furthermore, when the guide plate 403 is in the initial position, the guide plate 403 is inclined inward relative to the extension and retraction direction of the lifting cylinder 300, thus forming a channel that is narrow in the front and wide in the back, which guides the material for boxing. When the material touches the guide plate 403 on one side, the guide plate 403 compresses the spring 406, so there will be a certain floating ability, which will not cause the boxing to jam.

[0050] In other embodiments, other drive structures can be used to replace the needle cylinder 405 described above, such as an electric push rod.

[0051] As shown in Figure 9, the suction cup assembly 600 includes a connecting block 601, connecting posts 602, a suction cup limiting plate 603, and a suction cup 604. The suction cup limiting plate 603 is connected to the connecting block 601 via several connecting posts 602. The suction cup limiting plate 603 has through holes for the suction cup 604 to pass through. The suction cup 604 is connected to the air passage within the connecting block 601 for suction of the product to be packaged. The connecting block 601 is connected to the piston rod of the lifting cylinder 300, which controls the linear movement of the suction cup assembly 600.

[0052] The lifting cylinder 300 is located between two oppositely arranged fixed frames 104, and the top of the cylinder body of the lifting cylinder 300 is connected to the transition plate 105 or the movable support plate 103 in the lateral adjustment mechanism 200.

[0053] The working process of the device will be further explained below in conjunction with its structure.

[0054] Working principle: In the guide assembly, the needle-type cylinder 405 extends to control the guide plate clamping plate 402 to rotate outward, causing the guide plate 403 to open; then, the piston rod of the lifting cylinder 300 extends, and the suction cup assembly 600 uses the suction cup 604 to pick up the material (such as a charger or toothbrush handle). Then, the needle-type cylinder 405 retracts, and the elastic force of the spring 406 is released to push the guide plate clamping plate 402 to reset it. Then, all the guide plates 403 close into a contracted state, which plays a role in fixing and guiding; then, the guide assembly enters the packaging box, with the guide plate 403 entering the packaging box by about 5mm. At this time, the needle-type cylinder 405 extends to control the guide plate 403 to open, opening the packaging box opening and preventing jamming during the boxing process. Then, the lifting cylinder 300 continues to extend, pushing the picked-up material into the packaging box to complete the boxing action and remove the guide assembly.

[0055] Working process: When in use, this utility model is mounted on the robotic arm of a six-axis robot and located on one side of the packaging station of the packaging box conveyor line. The packaging box conveyor line is running continuously. After the photoelectric sensor switch on the conveyor line senses the position of the first packaging box entering the packaging station, the six-axis robot drives the device of this utility model to follow the positions of the first and second packaging boxes and put the materials into the two packaging boxes together according to the above process.

[0056] Example 2

[0057] The difference between this embodiment and embodiment 1 is that only one longitudinal adjustment mechanism 200 is provided in this embodiment, so that one packaging box is packed at a time.

[0058] In other embodiments, the longitudinal adjustment mechanism 200 is provided with more than two base mounting plates 203.

[0059] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
