Description

Technical Field

[0001] This invention relates to the field of inkjet printer technology, and in particular to a material lifting mechanism and lifting method. Background Technology

[0002] Existing inkjet equipment typically employs UV coding technology, which refers to printing using UV inks. It is widely used in industries such as food, pharmaceuticals, daily chemicals, label printing, card making, packaging printing, medical, electronics, and hardware. During the coding process, materials need to be transported to different workstations via the inkjet equipment's transport mechanism for different processing steps.

[0003] UV inkjet printing technology requires high positional accuracy of materials. However, during transmission, materials are prone to horizontal displacement, and the large drop during the ascent makes it difficult to guarantee height accuracy. These factors all affect the positional accuracy of the materials, thus affecting the quality of the finished inkjet printed product. Summary of the Invention

[0004] The purpose of this invention is to provide a material lifting mechanism and lifting method for material transport, which can effectively ensure the positional accuracy of the material and guarantee the quality of the finished product.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a material lifting mechanism is provided, including:

[0007] A liftable carrying pallet, wherein the carrying pallet is provided with a positioning component, the positioning component being able to confine the material on the carrying pallet;

[0008] A first limiting component is disposed above the carrying tray, and the carrying tray can rise to a first height that is limited and abuts against the first limiting component;

[0009] The second limiting component is disposed above the first limiting component;

[0010] A first driving member is used to drive the material to detach from the support tray and continue to rise, so that the material can rise to a second height that abuts against the second limiting component.

[0011] Preferably, the material lifting mechanism further includes a first correction component, which is located above the carrying tray and includes two opposing first correction parts. Both first correction parts extend along a first direction, and the sides of the two first correction parts facing each other are provided with a plurality of first rollers spaced apart along their extension direction. When the material passes between the two first correction parts, the first rollers can roll and contact the material to straighten the material.

[0012] Preferably, the second limiting component includes multiple positioning cover plates, and the material lifting mechanism further includes a support frame. A passage groove is provided on the top plate of the support frame. The multiple positioning cover plates are circumferentially spaced on the top plate along the passage groove, and one end of each positioning cover plate extends into the passage groove. The material can be limited and abutted against the portion of the multiple positioning cover plates that extends into the passage groove.

[0013] Preferably, the system also includes a second correction component, which is disposed on the side of the top plate facing away from the positioning cover plate and includes two second correction parts with an adjustable spacing in a second direction. The two second correction parts are located on both sides of the material, and the two second correction parts can abut against the two first sides of the material in the second direction.

[0014] Preferably, the second correction component further includes two third correction parts with adjustable spacing in the first direction. The two third correction parts are located on both sides of the material, and the two third correction parts can abut against the two second sides of the material in the first direction. The second direction is perpendicular to the first direction.

[0015] Preferably, the system also includes a second drive unit, the output end of which is connected to the carrying pallet and is used to drive the carrying pallet to rise and fall.

[0016] Preferably, the first limiting component includes multiple limiting posts, which are spaced apart circumferentially along the support tray and located above the support tray. The support tray is provided with multiple limiting holes, which correspond one-to-one with the multiple limiting posts. The support tray can be raised and lowered to allow the limiting posts to be inserted into the corresponding limiting holes.

[0017] Preferably, the positioning component includes a plurality of positioning blocks, which are spaced apart circumferentially along the carrying pallet, and together with the carrying pallet, the plurality of positioning blocks form a positioning space, and the material is confined within the positioning space.

[0018] Preferably, the support tray is provided with a clearance hole, and the output end of the first drive member can abut against the material through the clearance hole to drive the material to rise and fall away from the support tray.

[0019] On the other hand, a material lifting method is provided, which uses the material lifting mechanism described above, and includes the following steps:

[0020] S1. Place the material on the carrier pallet and limit the material to the carrier pallet by the positioning component on the carrier pallet;

[0021] S2. Drive the carrying tray to rise until the carrying tray rises to a first height that abuts against the first limiting component;

[0022] S3. Activate the first driving component to drive the material away from the carrying tray and rise to a second height that abuts against the second limiting component. At this time, the material rises to the target height.

[0023] The beneficial effects of this invention are as follows: The material lifting mechanism and method provided by this invention, when lifting materials, first place the materials on a support tray, and limit the materials to the support tray by a positioning component on the support tray; then drive the support tray to rise until the support tray rises to a first height that abuts against the first limiting component; then activate the first driving component, causing the first driving component to lift the materials off the support tray and continue to rise until it rises to a second height that abuts against the second limiting component, at which point the materials have risen to the target height. The setting of the first and second limiting components divides the material lifting process into two stages, so as to lift the materials in stages. During the lifting process, the height of the materials is positioned twice by the first and second limiting components, thereby effectively ensuring the height accuracy of the materials and avoiding the tilting of the materials due to large differences in the rise and fall; the positioning component can limit the materials to the support tray, ensuring the stability of the material and the support tray, preventing the materials from shifting in the horizontal direction, and preventing the materials from falling off the support tray.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0043] This embodiment provides a material lifting mechanism that can be used in conjunction with inkjet equipment for material transport, effectively ensuring material positioning accuracy and finished product quality. (See also...) Figures 1 to 6 The material lifting mechanism includes a support tray 1, a first limiting component, a second limiting component, and multiple first driving components 4. The support tray 1 is liftable and has a positioning component that limits the material to its position on the support tray 1. The first limiting component is positioned above the support tray 1, allowing the support tray 1 to rise to a first height where it abuts against the first limiting component. The second limiting component is positioned above the first limiting component. The first driving components 4 drive the material to detach from the support tray 1 and continue rising, allowing the material to rise to a second height where it abuts against the second limiting component.

[0044] The material lifting mechanism provided in this embodiment first places the material on the support tray 1, and the positioning component on the support tray 1 confines the material to the support tray 1. Then, the support tray 1 is driven to rise until it reaches a first height that abuts against the first limiting component. After that, the first driving component 4 is activated, causing the first driving component 4 to lift the material off the support tray 1 and continue to rise until it reaches a second height that abuts against the second limiting component. At this point, the material has risen to the target height. The first and second limiting components divide the material lifting process into two stages, allowing for segmented lifting of the material. During the lifting process, the height of the material is positioned twice by the first and second limiting components, effectively ensuring the height accuracy of the material and preventing the material from tilting due to a large difference in elevation. The positioning component confines the material to the support tray 1, ensuring the stability of the material's position relative to the support tray 1, preventing the material from shifting in the horizontal direction, and preventing the material from detaching from the support tray 1.

[0045] Optionally, the second limiting component includes multiple positioning cover plates 3, and the material lifting mechanism includes a support frame 6. A passage groove 61 is provided on the top plate 61 of the support frame 6. The multiple positioning cover plates 3 are spaced apart circumferentially on the top plate 61 along the passage groove 611, with one end of each positioning cover plate 3 extending into the passage groove 611. The material can be limited and abutted against the portions of the multiple positioning cover plates 3 extending into the passage groove 611. For ease of description, the position where the carrying pallet 1 is limited and abutted against the first limiting component is defined as the first position, and the position where the material is limited and abutted against the second limiting component is defined as the second position. When the carrying pallet 1 is in the first position, the first driving component 4 is driven to lift the material away from the carrying pallet 1 until the material rises to the second position. In the second position, the top surface of the material abuts against the portions of the multiple positioning cover plates 3 extending into the passage groove 611, at which point the material is lifted into position. Traditional positioning covers 3 are mostly one-piece designs, which makes it difficult to guarantee processing precision. When the top or bottom surface of the material is uneven, they cannot fully contact the material. Furthermore, the heat from UV curing can cause significant deformation in one-piece positioning covers 3, resulting in poor positioning performance. Multiple positioning covers 3 spaced circumferentially along the groove 611 allow for multi-point contact with the top surface of the material. This provides greater flexibility and easier processing compared to one-piece covers, effectively solving the above problems and ensuring high precision of the material. Optionally, the positioning covers 3 can be made of P20 stainless steel or SUS440C stainless steel, which maintains its shape at high temperatures and is not easily deformed, preventing deformation caused by the heat from UV curing.

[0046] Preferably, the positioning cover plate 3 is detachably connected to the top plate 61, thereby facilitating its maintenance and replacement and reducing processing difficulty. Optionally, the positioning cover plate 3 is detachably connected to the top plate 61 by bolts.

[0047] Optionally, photoelectric sensors 613 are provided at each of the four corners of the top plate 61 to ensure the installation accuracy of the positioning cover plate 3. Simultaneously, the photoelectric sensors 613 can also measure whether the material is in contact with the multiple positioning cover plates 3, thereby determining whether the material has been lifted into position. The working principle and usage method of the photoelectric sensors 613 are existing technologies and will not be described in detail in this embodiment.

[0048] Optionally, the support frame 6 includes a base plate 62, a top plate 61, and multiple columns 63. The multiple columns 63 are arranged parallel to each other in the vertical direction, and the top plate 61 and the base plate 62 are arranged opposite each other at both ends of the multiple columns 63. Optionally, both the top plate 61 and the base plate 62 are connected to the columns 63 by bolts, and the levelness of the top plate 61 and the base plate 62 can be adjusted by turning the bolts. Further, the material lifting mechanism also includes a transmission assembly, which includes two conveyor belts 8 arranged opposite each other on the base plate 62. The conveyor belts 8 can drive the carrying pallet 1 to move for material transmission. The configuration of the conveyor belts 8 is prior art and will not be described in detail in this embodiment.

[0049] Optionally, the first limiting component includes multiple limiting posts 2, which are spaced apart circumferentially along the carrying tray 1 and located above the carrying tray 1. The carrying tray 1 has multiple limiting holes 11, which correspond one-to-one with the multiple limiting posts 2. The carrying tray 1 can be raised and lowered to allow the limiting posts 2 to be inserted into the corresponding limiting holes 11. Specifically, the base plate 62 has multiple support plates 621, which correspond one-to-one with the multiple limiting posts 2. Each support plate 21 includes a first plate 6211 and a second plate 6212 that are vertically connected. The end of the first plate 6211 away from the second plate 6212 is connected to the base plate 62. The limiting posts 2 are located on the second plate 6212. When the carrying tray 1 rises to the point where the limiting post 2 is inserted into the corresponding limiting hole 11, it indicates that the first lifting is in place. Multiple limiting posts 2 are spaced apart along the circumference of the carrying tray 1, so that the carrying tray 1 and the first limiting component form multi-point contact, ensuring the stability of the limiting of the carrying tray 1 and the first limiting component.

[0050] Furthermore, a second driving component is also included. The output end of the second driving component can be connected to the carrier tray 1 and used to drive the carrier tray 1 to rise and fall. The second driving component facilitates the raising and lowering of the carrier tray 1 and is easy to adjust. Optionally, the second driving component is an electric cylinder or a pneumatic cylinder, etc., which is communicatively connected to the control system of the inkjet equipment to automatically control the raising and lowering of the carrier tray 1 through the control system. In this embodiment, the second driving component is mounted on the support frame 6.

[0051] Optionally, see Figure 4The support tray 1 is provided with clearance holes 12. The output end of the first driving component 4 can abut against the material through the clearance holes 12 to drive the material to rise and fall away from the support tray 1. The clearance holes 12 can avoid the output end of the first driving component 4, so that the first driving component 4 can drive the material to rise and fall away from the support tray 1, avoiding interference between the output end of the first driving component 4 and the support tray 1. Optionally, the first driving component 4 can be an electric cylinder or a pneumatic cylinder, etc., and can be communicated with the control system of the inkjet equipment to automatically control the lifting of the material through the control system. Preferably, multiple first driving components 4 are arranged at intervals, and multiple first driving components 4 form multi-point contact with the material to ensure the stability and uniformity of lifting the material. Correspondingly, multiple clearance holes 12 are provided, and each is arranged in a one-to-one correspondence with multiple first driving components 4. In this embodiment, four first driving components 4 are provided.

[0052] Optionally, the output pressure of the first driving member 4 can be controlled by a control system to prevent the first driving member 4 from damaging the material. In another optional embodiment, an elastic element can be provided between the output end of the first driving member 4 and the material. The elastic element can buffer the force between the material and the first driving member 4 to prevent the first driving member 4 from damaging the material. Optionally, the elastic element is a spring.

[0053] Preferably, the material lifting mechanism further includes a first correction component 5, which is located above the carrying tray 1 and includes two opposing first correction parts 51, both of which are along a first direction ( Figure 1 Extending in the X direction, each of the two first correction sections 51 has multiple first rollers 511 spaced apart along its extension direction on its side facing each other. When material passes between the two first correction sections 51, the first rollers 511 can roll and contact the material to straighten it. Specifically, during material transfer, the material is placed on the support tray 1, which can move along the conveyor line of the inkjet equipment and be moved into the material lifting mechanism by two conveyor belts 8. During the process of the material entering the material lifting mechanism, the multiple rollers on the two first correction sections 51 can roll and contact the material in the second direction (X direction). Figure 1 The two first side surfaces on the Y-axis (in the middle direction) roll into contact, thereby straightening the material in the second direction and preventing it from shifting in the second direction, thus ensuring the accuracy of the material in the first direction. It should be noted that the first direction and the second direction are perpendicular to the vertical direction.

[0054] Optionally, a connecting frame 64 is provided on the support frame 6, and the first correction part 51 is connected to the connecting frame 64 to ensure a stable connection between the first correction part 51 and the support frame 6, thereby ensuring the stability of the overall mechanism.

[0055] Optionally, a second correction component 7 is also included. The second correction component 7 is disposed on the side of the top plate 61 facing away from the positioning cover plate 3, and includes two second correction parts with an adjustable distance in the second direction. The two second correction parts are located on both sides of the material, and the two second correction parts can abut against the two first sides of the material in the second direction. During the process of the carrying pallet 1 entering the material lifting mechanism, the distance between the two second correction parts is adjusted so that the two second correction parts abut against the two first sides of the material in the second direction. The two first correction parts and the two second correction parts cooperate to perform secondary straightening of the material in the second direction, thereby ensuring the accuracy of the material in the second direction.

[0056] Similarly, the second correction assembly 7 also includes two third correction parts with adjustable spacing in the first direction. These two third correction parts are located on both sides of the material and can correspond one-to-one with the two second sides of the material in the first direction, which are perpendicular to the first direction. During the process of the material being lifted from the first position to the second position, the spacing between the two third correction parts is adjusted so that they abut against the two second sides of the material in the first direction, thereby preventing the material from shifting in the first direction during its ascent and ensuring the accuracy of the material in the first direction.

[0057] Optionally, the second correction unit includes a movable bracket 71 and second rollers 72 disposed on the movable bracket 71. Multiple second rollers 72 are spaced apart along a first direction. The movable bracket 71 can move along a second direction towards or away from the material, so that the second rollers 72 make rolling contact with the two first sides of the material in the second direction. With this configuration, the distance between the two second correction units can be adjusted by driving the two movable brackets 71 to move towards or away from each other, allowing the second rollers 72 on the movable bracket 71 to make rolling contact with the two first sides of the material in the second direction, thus straightening the material in the second direction. The arrangement of multiple second rollers 72 allows the second correction unit to form multi-point contact with the two first sides of the material, further ensuring the positioning accuracy of the material. In this embodiment, three second rollers 72 are provided.

[0058] Preferably, a guide rail is provided on the top plate 61 along the moving direction of the movable support 71, and the movable support 71 is slidably connected to the guide rail. A third driving member 73 is provided on the top plate 61, and the output end of the third driving member 73 is connected to the movable support 71 to drive the movable support 71 to slide along the guide rail. The guide rail provides guidance for the movement of the movable support 71 and also limits the movement stroke of the movable support 71, ensuring the stability of the movement of the movable support 71. Optionally, the third driving member 73 is an electric cylinder or a pneumatic cylinder, etc., and is communicatively connected to the control system of the inkjet equipment. Optionally, a guide groove is provided on the guide rail along its extension direction, and a slider is provided on the movable support 71. The slider is engaged with the guide groove and slides with the guide groove, thereby realizing the sliding connection between the movable support 71 and the top plate 61.

[0059] Optionally, the third correction unit includes a movable plate 74 and third rollers 75 disposed on the movable plate 74. Multiple third rollers 75 are spaced apart along the height direction of the material. A mounting plate 612 is disposed on the top plate 61. The movable plate 74 is movably disposed on the mounting plate 612 along a first direction. The movable plate 74, by moving, allows the third rollers 75 to abut against the two second sides of the material in the first direction, thereby straightening the material in the first direction. The arrangement of multiple third rollers 75 allows the third correction unit to form multi-point contact with the two second sides of the material in the first direction, further ensuring the positioning accuracy of the material. In this embodiment, two third rollers 75 are provided.

[0060] Furthermore, a limiting groove is provided on the mounting plate 612 along the moving direction of the moving plate 74. A locking block is provided on the moving plate 74, which engages with and slides within the limiting groove. A fourth driving component 76 is provided on the mounting plate 612, the output end of which is connected to the moving plate 74 to drive the moving plate 74 to slide along the limiting groove. Activating the fourth driving component 76 drives the moving plate 74 to slide, so that the third roller 75 abuts against the two second sides of the material in the first direction. Optionally, the fourth driving component 76 is an electric cylinder or a pneumatic cylinder, etc., and is communicatively connected to the control system of the inkjet equipment to automatically control the movement of the third correction unit through the control system.

[0061] Furthermore, each end of the top plate 61 is provided with a connecting plate 614, and the mounting plate 612 is connected to the top plate 61 through the connecting plate 614, thereby improving the connection strength between the mounting plate 612 and the top plate 61.

[0062] Optionally, the positioning component includes multiple positioning blocks 13, which are spaced apart circumferentially along the carrying pallet 1. The multiple positioning blocks 13 and the carrying pallet 1 together form a positioning space, within which the material is confined. When the material is placed on the carrying pallet 1, the multiple positioning blocks 13 abut against the material circumferentially, thereby stably confining the material within the positioning space and preventing the material from detaching from the carrying pallet 1 during material transfer.

[0063] This embodiment also provides a material lifting method, which uses the material lifting mechanism described above, and includes the following steps:

[0064] S1. Place the material on the carrier pallet 1 and use the positioning components on the carrier pallet 1 to keep the material on the carrier pallet 1;

[0065] S2. Drive the carrier pallet 1 to rise until the carrier pallet 1 rises to the first height where it is stopped and abutted by the first limiting component;

[0066] S3. Start the first driving component 4, so that the first driving component 4 drives the material to detach from the carrying tray 1 and rise to the second height where it is stopped by the second limiting component. At this time, the material rises to the target height.

[0067] Before step S2, the process further includes: placing the carrier tray 1 carrying the material on the conveyor line of the inkjet equipment; the conveyor line transports the carrier tray 1 to the transmission component of the material lifting mechanism; the transmission component drives the carrier tray 1 to move until the carrier tray 1 is completely inside the material lifting mechanism; at this time, the multiple clearance holes 12 on the carrier tray 1 correspond one-to-one with the multiple first drive members 4; during the process of the carrier tray 1 entering the material lifting mechanism, the first rollers 511 on the two first correction parts 51 roll into contact with the two first sides of the material in the second direction; at the same time, the two third drive members 73 are activated, causing the second rollers 72 of the two second correction parts to move along the second direction and approach the material, so that the second rollers 72 of the two second correction parts roll into contact with the two first sides of the material, thereby straightening the material in the second direction.

[0068] In step S2, the second driving component is activated to drive the carrier pallet 1 to rise until the limiting post 2 of the first limiting component is inserted into the corresponding limiting hole 11 on the carrier pallet 1 (at this time, the carrier pallet 1 is in the first position) so as to achieve the first height positioning of the material.

[0069] In step S3, multiple first driving components 4 are activated simultaneously, causing the top surface of the material to abut against multiple positioning cover plates 3 (at this time, the carrying tray 1 is in the second position), and two fourth driving components 76 are activated, causing the third rollers 75 of the two third correction parts to move along the first direction and approach the material until the third rollers 75 of the two third correction parts respectively roll into contact with the two second sides of the material in the first direction, so as to straighten the material in the first direction.

[0070] The material lifting method also includes the following steps:

[0071] S4. The carrier tray 1 remains in the second position so that the inkjet equipment can inkjet and cure the material.

[0072] S5. After processing is completed, the third drive unit 73 and the two fourth drive units 76 are activated to move the second roller 72 and the third roller 75 away from the material, and the first drive unit 4 is activated to drive the material down to the first position. Then the second drive unit is activated to lower the carrying tray 1 onto the transfer assembly.

[0073] The material lifting mechanism and method provided in this embodiment can prevent materials from tilting or deviating due to large lifting differences, effectively ensuring the positional accuracy of the materials and the quality of the finished product. Furthermore, the method of positioning the material on the material lifting mechanism reduces the number of positioning operations compared to sequentially positioning boxes at each station on the conveyor line, resulting in higher positioning efficiency.

[0074] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
