Description

Technical Field

[0001] This invention relates to a conveying device, and more specifically to a continuous paperboard output device. Background Technology

[0002] Cardboard is frequently used as a packaging material. Before being folded into cartons, cardboard is stacked in sheets. Then, the sheets of cardboard are fed into a folding machine to be folded into cartons. Current cardboard conveying devices all use a top-in, top-out method. This method means that cardboard cannot be removed when it is being put in. In other words, when cardboard is added to the cardboard bin, the cardboard removal operation must be paused. Therefore, continuous cardboard removal cannot be achieved, which affects the efficiency of the entire production line. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous paperboard output device that can effectively solve the problem that existing paperboard conveying equipment cannot achieve continuous paperboard conveying.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0005] A continuous cardboard output device includes a frame, a conveying mechanism, a suction mechanism, and a extraction mechanism. The frame has a cardboard storage area, and the conveying mechanism has a conveying component that feeds cardboard into the cardboard storage area. The suction mechanism is located on the frame below the cardboard storage area and includes a vertical lifting device and a suction cup. The vertical lifting device is located on the frame and controls the vertical movement of the suction cup. The suction cup is located below one side of the cardboard and is used to move one side of the bottom layer of cardboard downwards. The extraction mechanism includes a first horizontal moving component and a pair of opposing rotating rollers. The first horizontal moving component is located on the frame and drives the rollers to move towards one side of the cardboard.

[0006] Preferably, the conveying mechanism further includes a conveying support and a second horizontal moving component that drives the conveying support to move toward the cardboard storage area, the conveying component being mounted on the conveying support. The conveying support supports the conveying component, and the second horizontal moving component allows the conveying support to have a greater range of movement in the horizontal direction, facilitating the stacking of cardboard onto the conveying component.

[0007] Preferably, the second horizontal moving component includes a second horizontal drive motor, a second synchronous belt, a second slide rail, and a second slider. Both the second horizontal drive motor and the second slide rail are fixed to the frame. The second horizontal drive motor drives the second synchronous belt. The conveying bracket is fixedly connected to the second synchronous belt, and the conveying bracket is provided with a second slider that cooperates with the second slide rail. The cooperation between the second slider and the second slide rail reduces the resistance when the conveying bracket moves relative to the frame, and the second horizontal drive motor drives the second synchronous belt, accurately controlling the displacement distance of the conveying bracket.

[0008] Preferably, the conveying assembly includes multiple parallel conveyor supports, one end of each conveyor support fixed to the conveying support frame. Each conveyor support is equipped with a synchronous conveyor belt, a conveyor motor, and a conveyor shaft driven by the conveyor motor. The conveyor shaft drives all synchronous conveyor belts. Using multiple parallel conveyor supports provides sufficient support for the support plate while reducing the width of a single synchronous conveyor belt. Furthermore, the spacing between the conveyor supports can be adjusted according to the width of the carton, accommodating various types of cardboard. Since all synchronous conveyor belts are driven by the conveyor motor via the conveyor shaft, synchronized operation of all synchronous conveyor belts is achieved, reducing control complexity and manufacturing costs.

[0009] Preferably, the entrance to the cardboard storage area is equipped with a blocking door, which includes an upper door and a lower door. The upper door is swaying on the frame, with its swaying direction opposite to the cardboard storage area. The lower door is vertically slidable on the frame. The blocking door prevents the addition of cardboard to the cardboard storage area when there is sufficient cardboard remaining. The upper door opens by swinging outwards. If the conveyor malfunctions and prematurely delivers cardboard to the blocking door, the upper door will be blocked by the cardboard and cannot open until the conveyor returns to its correct position. The lower door moves vertically, working in conjunction with the upper door to prevent cardboard boxes from entering from two directions.

[0010] Preferably, the frame is further provided with a horizontally arranged slide bar and a lead screw. An adjusting motor for driving the lead screw to rotate is fixed on the frame. The blocking door is mounted on a gantry, which is slidably connected to the slide bar. A nut that threadedly engages with the lead screw is fixed on the gantry. By adjusting the position of the gantry, the size of the cardboard storage area can be adjusted. Furthermore, the relative position of the gantry can be precisely adjusted using the lead screw and nut, and the slide bar assists in ensuring smooth horizontal sliding of the gantry relative to the frame.

[0011] Preferably, the gantry is equipped with a horizontally arranged rotating shaft, the top of the upper door is fixed to the rotating shaft, and the gantry is equipped with a swing cylinder to drive the rotating shaft to rotate; both ends of the lower door are equipped with a fourth slider and a vertically arranged rack, and both sides of the gantry are equipped with vertically driven cylinders connected to both ends of the lower door respectively. The gantry is equipped with a fourth slide rail that cooperates with the fourth slider, and the fourth slide rail is vertically arranged. The gantry is also rotatably connected to a synchronous rotating rod, and a gear that cooperates with the rack is fixed on the synchronous rotating rod. The upper door is opened and closed by rotating the rotating shaft driven by the swing cylinder, while the lower door is moved up and down directly by the vertical cylinder. In order to ensure that the vertical movement distances of the lower door on both sides are equal, racks are provided on both sides of the lower door, and the synchronous vertical movement of the lower door on both sides is achieved by the synchronous rotating rod with gears.

[0012] Preferably, the suction mechanism further includes a suction bracket, and the vertical lifting device includes a third slider, a third slide rail, and a first transmission wheel. Multiple suction cups are present and fixed to the suction bracket. The third slide rail is vertically arranged and fixed to the frame. The third slider is fixed to the suction bracket and slidably engages with the third slide rail. The first transmission wheel is rotatably mounted on the frame and drives the suction bracket to move vertically. The rotation of the first transmission wheel drives the suction bracket to move up and down, performing a suction operation on one side of the cardboard. The transmission wheel mechanism is simple and reliable to operate and easy to maintain.

[0013] Preferably, the extraction mechanism further includes an extraction bracket. The first horizontal moving component includes a first slider, a first slide rail, and a second transmission wheel. A pair of opposing rotating rollers are rotatably mounted on the extraction bracket. The first slide rail is horizontally fixed to the frame. The first slider is fixed to the extraction bracket and slidably connected to the first slide rail. The second transmission wheel is rotatably connected to the frame and drives the extraction bracket to move horizontally. Similarly, the transmission wheel mechanism drives the extraction bracket to move horizontally, ensuring that the extraction bracket can perform multiple continuous reciprocating movements.

[0014] Preferably, the frame within the cardboard storage area is further provided with a pair of transverse limiting clamps, which are slidably mounted on the frame; a longitudinal limiting plate is also provided on the frame between the transverse limiting clamps, which is slidably mounted on the frame along the longitudinal direction. The transverse limiting clamps adjust the transverse space of the cardboard storage area, while the longitudinal limiting clamps adjust the longitudinal space, thus accommodating more cardboard of different specifications.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] A continuous cardboard output device includes a frame, a conveying mechanism, a suction mechanism, and a extraction mechanism. The frame houses a cardboard storage area, and the conveying mechanism includes a conveying component that feeds cardboard into the storage area. The suction mechanism is mounted on the frame below the storage area and includes a vertical lifting device and a suction cup. The vertical lifting device controls the vertical movement of the suction cup, which is located below one side of the cardboard and is used to move the bottommost layer of cardboard downwards. The extraction mechanism includes a first horizontal moving component and a pair of opposing rotating rollers. The first horizontal moving component is mounted on the frame and drives the rollers to move towards one side of the cardboard. By using the suction mechanism to grip the main board from below and the extraction mechanism to remove it, the problem of current cardboard conveying equipment being unable to continuously transport cardboard is solved. The conveying mechanism continuously adds cardboard to the cardboard storage area, while the suction mechanism picks up one side of the cardboard from below the storage area and moves the bottom layer of cardboard downwards. Then, the extraction mechanism uses a pair of opposing rotating rollers to extract the bottom layer of cardboard from the storage area. This ensures that the addition and extraction of cardboard do not interfere with each other, allowing for the simultaneous addition and extraction of cardboard and enabling continuous output of cardboard.

[0034] A continuous cardboard output device includes a frame, a conveying mechanism, a suction mechanism, and a extraction mechanism. The frame houses a cardboard storage area, and the conveying mechanism includes a conveying component that feeds cardboard into the storage area. The suction mechanism is mounted on the frame below the storage area and includes a vertical lifting device and a suction cup. The vertical lifting device controls the vertical movement of the suction cup, which is located below one side of the cardboard and is used to move the bottommost layer of cardboard downwards. The extraction mechanism includes a first horizontal moving component and a pair of opposing rotating rollers. The first horizontal moving component is mounted on the frame and drives the rollers to move towards one side of the cardboard. By using the suction mechanism to grip the main board from below and the extraction mechanism to remove it, the problem of current cardboard conveying equipment being unable to continuously transport cardboard is solved. The conveying mechanism continuously adds cardboard to the cardboard storage area, while the suction mechanism picks up one side of the cardboard from below the storage area and moves the bottom layer of cardboard downwards. Then, the extraction mechanism uses a pair of opposing rotating rollers to extract the bottom layer of cardboard from the storage area. This ensures that the addition and extraction of cardboard do not interfere with each other, allowing for the simultaneous addition and extraction of cardboard and enabling continuous output of cardboard.

[0039] See Figure 1 , Figure 2 This invention provides an embodiment of a continuous paperboard output device, which includes a frame 100, a conveying mechanism 200, a suction mechanism 300, and a extraction mechanism 400. The frame 100 provides fixed support for the other mechanisms. A paperboard storage area 110 is provided within the frame 100. The conveying mechanism 200 primarily feeds paperboard into the paperboard storage area 110. The suction mechanism 300 grips one side of the bottommost paperboard from below the mainboard storage area and moves downwards to separate one side of the bottommost paperboard from the paperboard above it. The extraction mechanism 400 is mainly responsible for "grabbing" the side of the bottommost paperboard that is separated from the paperboard above it and extracting the bottommost paperboard. The specific structure is as follows:

[0040] like Figure 1 , Figure 2 , Figure 3 As shown, the conveying mechanism 200 includes a conveying bracket 220, a second horizontal moving component 230 that drives the conveying bracket 220 to move toward the cardboard storage area 110, and a conveying component 210. The conveying component 210 is mounted on the conveying bracket 220 and drives the cardboard placed on the conveying bracket 220 into the cardboard storage area 110. The second horizontal moving component 230 includes a second horizontal drive motor 231, a second synchronous belt 232, a second slide rail 233, and a second slider 234. The second slider 234 is fixed on the left and right sides of the conveying bracket 220 along the cardboard conveying direction. The second slide rail 233 is provided at the corresponding position on the frame 100. By cooperating with the second slide rail 233, the friction between the conveying bracket 220 and the frame 100 can be reduced when the conveying bracket 220 slides relative to the frame 100. The second synchronous belt 232 is fixed to the right side of the conveyor bracket 220, and the second horizontal drive motor 231 is fixed to the frame 100. The second synchronous belt 232 is driven by the second horizontal drive motor 231, thereby driving the conveyor bracket 220 to move towards or away from the cardboard storage area 110 relative to the frame 100. The reason for setting up a movable conveyor bracket 220 is to facilitate the better feeding of cardboard into the cardboard storage area 110.

[0041] The conveying assembly 210 includes multiple parallel conveying supports 211, one end of which is fixed to a conveying support 220. A support rod 170 is mounted on the frame 100, and rollers 180 are fitted onto the support rod 170. The other end of the conveying support 211 rests on the corresponding roller 180. The support rod 170 provides support to the conveying support 211 and continuously supports the conveying support 211 as the conveying support 220 slides relative to the frame 100. Each conveying support 211 is equipped with a synchronous conveying belt 212, one side of which is located on the upper surface of the conveying support 211. The conveying support 211 supports the synchronous conveying belt 212, which directly contacts the cardboard, facilitating the control of the cardboard movement and its delivery into the cardboard storage area 110. In order to drive all the synchronous conveyor belts 212 to run simultaneously, a conveyor shaft 250 is rotatably mounted on the conveyor support 220. A conveyor motor 240 that drives the conveyor shaft 250 to rotate is fixed at one end of the conveyor support 220. All the synchronous conveyor belts 212 bypass the conveyor shaft 250 and drive all the synchronous conveyor belts 212 to run synchronously through the conveyor shaft 250, thereby ensuring that the cardboard will not deviate when conveying the cardboard.

[0042] like Figures 4 to 6 As shown, a blocking door 120 is provided at the entrance of the cardboard storage area 110, and the blocking door 120 can be slidably mounted on the frame 100 to adjust the size of the cardboard storage area 110. Specifically, the frame 100 is provided with a horizontally arranged slide bar 190 and a lead screw 140. The slide bar 190 is provided on both sides of the frame 100, while the lead screw 140 is provided only on one side of the frame 100. An adjustment motor 150 is provided on the frame 100 to drive the lead screw 140 to rotate. The blocking door 120 includes a door frame 160. The door frame 160 has fifth sliders on both sides that cooperate with the corresponding slide bars 190, and a nut is provided on one side of the door frame 160 that is threadedly engaged with the lead screw 140. In this way, the adjustment motor 150 can drive the door frame 160 to move relative to the frame 100.

[0043] The blocking door 120 also includes an upper door 121 and a lower door 122. The upper door 121 swings open in the direction of the conveying mechanism 200, and the lower door 122 moves vertically. The upper door 121 and the lower door 122 work together to control the opening and closing of the entrance to the cardboard storage area 110, so as to prevent the conveying mechanism 200 from mistakenly sending the cardboard into the cardboard storage area 110. Specifically, a rotating shaft 123 is rotatably connected to the gantry 160. The upper part of the upper door 121 is fixedly connected to the rotating shaft 123. A swing cylinder 124 is provided on one side of the gantry 160. The swing cylinder 124 controls the rotation of the rotating shaft 123 to achieve the swinging purpose of the upper door 121. Since the lower door 122 moves vertically, a fourth slide rail 130 is provided on opposite sides of the gantry 160. A fourth slider 125 is provided on both sides of the lower door 122. A vertical drive cylinder 127 is provided on one side of the gantry 160. The vertical drive cylinder 127 pushes the lower door 122 to slide up and down along the fourth slide rail 130.

[0044] Furthermore, in order to ensure the synchronization of both sides when the lower door 122 slides up and down, vertically arranged racks 126 are fixed on both sides of the lower door 122 respectively, and a synchronous rotating rod 128 is rotatably provided on the door frame 160. The two ends of the synchronous rotating rod 128 are respectively provided with gears 129 corresponding to the racks 126, and the synchronous lifting and lowering of both sides of the lower door 122 is realized by using the synchronous rotating rod 128.

[0045] If the adjustable gantry 160 is not provided in the continuous cardboard output device, then the gantry 160 in the above scheme will be fixedly connected to the frame 100 and become part of the frame 100, and the upper door 121 and lower door 122 are set in the same way as in the above scheme.

[0046] At least two blocking rollers 113 are provided at the bottom of the cardboard storage area 110. The rolling direction of the blocking rollers 113 is the same as the direction in which the cardboard is pulled out. The blocking rollers 113 can prevent the cardboard from falling out of the cardboard storage area 110 and also make the bottom layer of cardboard easier to pull out. Several adjusting grooves 114 are provided on the frame 100 at both ends of the blocking rollers 113. The two ends of the blocking rollers 113 are respectively locked in the adjusting grooves 114, and the position of the blocking rollers 113 can be adjusted according to the size of the cardboard storage area 110.

[0047] like Figure 7 , Figure 8As shown, the suction mechanism 300 includes a vertical lifting device 310, suction cups 320, and a suction bracket 330. The vertical lifting device 310 includes a third slider 340, a third slide rail 350, and a first transmission wheel 360. Multiple suction cups 320 are fixed on the suction bracket 330. The suction cups 320 can be arranged in a row, with their positions corresponding to the side of the bottom layer of cardboard away from the inlet of the cardboard storage area 110. The suction cups 320 are powered by an air pump. The third sliders 340 are provided on both sides of the suction bracket 330, and the corresponding frame 100 is provided with a third slide rail 350. The third slide rail 350 is vertically arranged to restrict the suction bracket 330 to move only in the vertical direction. A first transmission wheel 360 is provided on one side of the frame 100. An eccentric first connecting rod 370 is rotatably connected to the first transmission wheel 360. The other end of the first connecting rod 370 is rotatably connected to the suction bracket 330. Thus, the rotation of the first transmission wheel 360 drives the suction bracket 330 to slide vertically along the third slide rail 350.

[0048] like Figure 9 , Figure 10 The extraction mechanism 400 includes a first horizontal moving component 410, a pair of opposing rotating rollers 420, and an extraction bracket 430. The first horizontal moving component 410 includes a first slider 411, a first slide rail 412, and a second transmission wheel 413. The first slider 411 is provided on the left and right sides of the horizontal moving component, and the first slide rail 412 is provided at the corresponding position on the frame 100. The pair of opposing rotating rollers 420 are rotatably mounted on the extraction bracket 430, and the second transmission wheel 413 is rotatably mounted on the frame 100. An eccentric second connecting rod 414 is connected to the second transmission wheel 413, and the other end of the second connecting rod 414 is rotatably connected to the extraction bracket 430. Thus, the extraction bracket 430 is driven to slide horizontally along the first slide rail 412 by the rotation of the second transmission wheel 413.

[0049] Additionally, a pair of transverse limiting clamps 111 are provided on the frame 100 of the cardboard storage area 110, and a transverse guide rod 115 is provided on the frame 100. The pair of transverse limiting clamps 111 are slidably mounted on the transverse guide rod 115, thereby adjusting the transverse size of the cardboard storage area 110. Alternatively, a longitudinal limiting plate 112 can be provided between the transverse limiting clamps 111, and the longitudinal limiting plate 112 is slidably mounted on the frame 100 along the longitudinal direction, thereby adjusting the longitudinal space of the cardboard storage area 110. The first drive wheel 360 and the second conventional wheel can be powered by the same power source.

[0050] like Figure 1 , Figure 11 , Figure 12As shown, a sensor can be installed in the cardboard storage area 110 to detect the quantity of cardboard in the cardboard storage area 110. The process of adding cardboard is as follows: first, the stacked cardboard is placed on the conveying bracket 211 of the conveying mechanism 200. If there is not enough cardboard in the cardboard storage area 110, the swing cylinder 124 is activated to swing the upper door 121 outward. At the same time, the vertical drive cylinder 127 is activated to control the lower door 122 to move downward, so that the entrance of the cardboard storage area 110 is opened. Subsequently, the second horizontal drive motor 231 starts, driving the conveyor bracket 220 to move towards the cardboard storage area 110. When the front part of the conveyor bracket 211 enters or approaches the entrance of the cardboard storage area 110, the conveyor motor 240 starts, driving the conveyor timing belt 212 to run. The conveyor timing belt 212 will carry the cardboard on the conveyor bracket 211 into the cardboard storage area 110 and stack it on top of the remaining cardboard in the cardboard storage area 110. Then, the second horizontal drive motor 231 drives the conveyor bracket 220 back to the initial position, and the upper door 121 and lower door 122 close the entrance of the carton storage area.

[0051] The process of extracting the cardboard is as follows: The first drive wheel 360 rotates, causing the suction bracket 330 to move upward, so that the suction cup 320 contacts the end of the bottommost cardboard in the cardboard storage area 110 furthest from the inlet. Then, the suction cup 320 picks up the end of the cardboard. The first drive wheel 360 drives the suction bracket 330 downward, separating the end of the bottommost cardboard from the cardboard above it. Subsequently, the second drive wheel 413 starts, driving the extraction bracket 430 towards the cardboard, so that the separated end of the cardboard is inserted between the opposing rotating rollers 420. At the same time, the suction cup 320 releases its suction force. Using the rotation of the rollers 420, the bottommost cardboard is extracted from the cardboard storage area 110. Then, the second drive wheel 413 drives the extraction bracket 430 back to its initial position. This device does not interfere with the addition and extraction of cardboard, enabling continuous output of cardboard and improving cardboard output efficiency.

[0052] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
