Description

Technical Field

[0001] This invention relates to the field of waste removal technology, and specifically to a waste removal machine adapted to a die-cutting machine. Background Technology

[0002] After paper is die-cut by a die-cutting machine, waste edges will remain around the edges and in the middle of the product. Waste removal is required to obtain qualified products. Currently, there are three main waste removal methods in the industry: 1. Using a die-cutting machine with built-in waste removal function. However, such equipment is expensive, which increases production costs; 2. Manual waste removal, which is prone to low efficiency and uncontrollable finished product quality, resulting in increased labor costs and low production efficiency; 3. Using a separate waste removal machine.

[0003] Patent application CN202210938766.9 discloses a waste removal machine for a flatbed die-cutting machine. In this machine, a conveying mechanism transports paper to a label-removing honeycomb plate. An upper label-removing component moves along a crossbeam to directly above the honeycomb plate. A pin in the lower label-removing component extends along the honeycomb structure of the plate, lifting the die-cut paper onto the plate. A fork mechanism closes to support the paper. The paper lifted by the pin in the lower component is held by the fork mechanism. After the fork mechanism holds the paper, the upper label-removing component moves along the crossbeam towards a collection rack. When the upper component is fully in the collection rack and the lifting platform is in position, the fork mechanism opens, allowing the paper to fall freely onto the lifting platform. The finished product conveying process of this waste removal machine is very cumbersome, requiring the upper label-removing component and the fork mechanism to work together to convey the paper to the collection rack. This increases the steps involved in the upper label-removing component, resulting in a complex equipment structure and redundant production processes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a waste removal machine that is compatible with die-cutting machines, which addresses the shortcomings of the prior art and simplifies the overall structure and production process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waste removal machine adapted to a die-cutting machine, comprising a frame, a feeding mechanism extending outward from the input end on the frame, an upper label removal mechanism suspending above the feeding mechanism to push down the waste edge, a lower label removal mechanism pushing up the finished cardboard directly below the upper label removal mechanism, a waste collection trolley at the output end of the feeding mechanism, a stacking mechanism for collecting finished products arranged parallel to the frame on one side of the feeding mechanism, and a transfer mechanism on the upper label removal mechanism for transferring the delabeled finished products from the feeding mechanism to the stacking mechanism. The upper label removal mechanism includes a lifting frame and a drive lifting mechanism. The machine includes a label removal power assembly for lifting the frame and several sets of upper ejector pin assemblies mounted on the lifting frame. The transfer mechanism includes several sets of transfer arms linked to the lifting frame. The transfer arms are located below the upper ejector pin assemblies and are arranged in a cross shape. Each transfer arm includes a transfer base, a conveyor belt wound around the transfer base, and a transfer power assembly that drives the conveyor belt. The transfer base is suspended above the feeding mechanism and the stacking mechanism. One end of its length is located at the feeding mechanism, and the other end extends to the stacking mechanism. The conveyor belt is evenly distributed with several air holes for adsorbing or blowing off finished products. The frame is equipped with an air direction conversion device for switching the air direction inside the air holes.

[0006] The present invention, which has the above features, integrates the transfer mechanism on the upper label removal mechanism and links it with the lifting frame. When the lower label removal mechanism lifts the finished cardboard, the transfer arm directly absorbs the finished cardboard and transfers it to the palletizing mechanism via the conveyor belt, simplifying the overall structure and production process. A waste collection trolley is set at the output end of the feeding mechanism to directly collect waste edges. After it is full, it can be pushed to the waste disposal area for easy operation. The input end of the feeding mechanism extends outward to facilitate direct connection with the die-cutting machine output, eliminating the need for manual transfer and loading.

[0007] A further feature of this invention is that the airflow conversion device includes a main box, an auxiliary box connected to the main box, and a rotating shaft. The main box has an air intake port connected to the air intake device. The auxiliary box has an air intake port connected to the air blowing device and several first output ports. The first output ports are connected to the transfer arm via air pipes. One end of the rotating shaft is placed inside the auxiliary box and fitted with an airflow switching disc. The other end extends outward through the main box and is connected to the label removal power assembly. The main box and the auxiliary box are in communication and have a connecting hole between them. The airflow switching disc has several docking holes distributed circumferentially along its axis. When the airflow switching disc rotates until the docking holes coincide with the connecting holes, an air intake condition is formed in the first output ports. When the airflow switching disc rotates to cover the connecting holes, the air blowing device operates, and an air blowing condition is formed in the first output ports.

[0008] The present invention, possessing the above-mentioned features, achieves switching between suction and blowing modes within the same output air path through an air direction switching device, satisfying the process requirement of the transfer arm to first suction and then blow, eliminating the need for separate valves to control the suction and blowing air paths, resulting in high structural integration; the main box connects to the suction air source, and the auxiliary box connects to the blowing air source, with the suction and blowing air paths being independent of each other, relying on the rotation of the air direction switching disc to control the flow, avoiding cross-contamination and interference between the suction and blowing air sources; one rotation of the air direction switching disc is exactly one complete material cleaning and waste removal operation cycle.

The conveyor belt is equipped with a plurality of suction holes for adsorbing materials. The main box is equipped with a plurality of second output holes, which are connected to the conveyor belt through air pipes.

[0010] The present invention with the above features: the conveyor belt adsorbs the die-cut paper through the suction holes, preventing the die-cut paper from deviating during the label removal process, ensuring the accuracy of the label removal position, and improving the yield of finished products; after label removal, the finished paper is sucked away by the transfer arm, and the conveyor belt transports the waste edge forward.

[0011] A further feature of the present invention is that the plurality of connecting holes are distributed in a clockwise or counterclockwise direction along the axis of the wind direction switching disk, and a shielding part is formed between the first docking hole and the last docking hole. The shielding part is the part of the wind direction switching disk where no connecting holes are opened.

[0012] The present invention with the above features: the distribution of the docking holes and the shielding part corresponds to the waste cleaning process of the waste cleaning machine. The working condition can be switched by rotating the angle, which is convenient to match the action sequence of the transfer arm of the waste cleaning machine. When the transfer arm needs to pick up paper, the docking holes are connected to the connecting holes in sequence to continuously draw air. When the transfer arm needs to blow paper, the rotating shaft drives the air direction switching disk to rotate to the shielding part to cover the connecting hole to realize the blowing.

[0013] A further feature of the present invention is that the feeding mechanism further includes a honeycomb plate arranged in a horizontal direction, a plurality of guide rollers, and a feeding drive source. The plurality of guide rollers are respectively arranged at both ends of the honeycomb plate in the length direction and below the honeycomb plate. The conveyor belt is arranged around the honeycomb plate and the guide rollers, and the interior of the conveyor belt forms an installation space for the label removal mechanism to be installed.

[0014] The present invention having the above features: the lower label removal mechanism is arranged in the installation space within the conveyor belt, and the ejector component of the lower label removal mechanism can pass through the honeycomb plate and the suction hole of the conveyor belt to lift the paper upward, so as to realize the cooperation of the upper and lower label removal mechanisms to complete the separation of waste edge and finished product.

[0015] A further feature of the present invention is that the transfer mechanism includes a first guide rod assembly and a second guide rod assembly disposed on both sides of the lifting frame and linked thereto.

[0016] The present invention having the above features: the transfer arm is suspended and installed on both sides of the lifting frame through the first and second guide rod assemblies, and rises and falls synchronously with the lifting frame to ensure that the transfer arm and the upper pin move synchronously, so as to realize the synchronous label removal and material picking actions; the transfer arm can slide along the second slide rail, and the position of the transfer arm can be finely adjusted to adapt to paper products of different widths.

[0017] A further feature of this invention is that: the lower end of the lifting frame is provided with two parallel first slide rails at intervals; the two ends of the upper ejector assembly along its length are fixed to the first slide rails; the upper ejector assembly includes two first sliders, a first honeycomb narrow plate, a pressure plate, a mounting component, several upper ejectors, a connecting component, and a second honeycomb narrow plate; the first sliders are slidably connected to the first slide rails; the two ends of the first honeycomb narrow plate along its length are fixedly connected to the first sliders; the pressure plate is mounted above the first honeycomb narrow plate via the mounting component; one end of the connecting component is fixedly connected to the first honeycomb narrow plate, and the other end is fixedly connected to the second honeycomb narrow plate; the upper ejector includes a head placed between the pressure plate and the first honeycomb narrow plate, and a rod portion that passes through the first honeycomb narrow plate and the second honeycomb narrow plate sequentially and extends downwards.

[0018] The present invention, which has the above-mentioned features, uses an upper ejector pin as a label removal component. The upper ejector pin is a point contact component, which can perform point-to-point pressing on the small, scattered, and irregularly distributed waste edges to improve the quality of label removal and waste cleaning. The number of upper ejector pin components can be selected according to the actual shape of the waste edges. The overall position of the upper ejector pin components can be adjusted by sliding on the first slide rail to improve the flexibility of the upper ejector pin position adjustment.

[0019] A further provision of the present invention is that the mounting component includes a mounting base, a pressure block, a fastener, and a pin. The mounting base is fixedly disposed on the upper end face of the first honeycomb narrow plate. The pressure block includes a limiting part pressed against the upper end face of the pressure plate and a mounting part placed on the first honeycomb narrow plate. The mounting base has a mounting groove for accommodating the mounting part. There is an adjustment gap between the upper end face of the mounting part and the bottom of the mounting groove. The fastener passes through the mounting base, the limiting part, and the pressure plate in sequence and then abuts against the first honeycomb narrow plate. The pin passes through the mounting base and the mounting part in sequence and then abuts against the first honeycomb narrow plate. A spring is sleeved on the pin. One end of the spring abuts against the bottom of the mounting groove, and the other end abuts against the first honeycomb narrow plate.

[0020] The present invention, which has the above-mentioned features, enables the pressure block to have elastic floating ability by setting a spring. During the waste removal operation, the spring can extend and deform autonomously for paper of different thicknesses, and precisely adjust the pressing height of the upper pin to ensure that both thick and thin paper can maintain appropriate pressing force.

The air direction switching disk 94 has several docking holes 941 distributed circumferentially along its axis. When the air direction switching disk 94 rotates to the point where the docking hole 941 coincides with the connecting hole 912, a suction condition is formed in the first output hole 922. When the air direction switching disk 94 rotates to the point where the connecting hole 912 is blocked, the blowing device works and a blowing condition is formed in the first output hole 922. The operation of the blowing device is controlled by a solenoid valve.

[0046] Several connecting holes 912 are distributed clockwise or counterclockwise along the axis of the wind direction switching disk 94. A shielding part 942 is formed between the first docking hole 941 and the last docking hole 941. The shielding part 942 is the part of the wind direction switching disk 94 where no connecting holes 912 are opened.

[0047] The feeding mechanism 2 is equipped with a conveyor belt 21 that can adsorb materials and transport waste to the waste collection cart 5. The conveyor belt 21 is equipped with a number of suction holes 211 for adsorbing materials. The main box 91 is equipped with a number of second output holes 913, which are connected to the conveyor belt 21 through air pipes.

[0048] The feeding mechanism 2 also includes a honeycomb plate 22 arranged in the horizontal direction, a number of guide rollers 23 and a feeding drive source 24. The number of guide rollers 23 are respectively arranged at both ends of the honeycomb plate 22 in the length direction and below the honeycomb plate 22.

The inside of the conveyor belt 21 forms an installation space for the label removal mechanism 4 to be installed.

[0049] The labeling mechanism 7 includes a paper storage base 71, a top label assembly 72 for lifting paper onto the paper, a label suction arm 73 for adsorbing paperboard, and a labeling power assembly 74 for driving the label suction arm 73 to enter or leave the palletizing mechanism 6. The top label assembly 72 includes a top label block 741 connected to the paper storage base 71 and a top label power assembly 742 for driving the top label block to rise and fall. The label suction arm 73 is suspended above the paper storage base 71.

[0050] The die-cut cardboard processed by the die-cutting machine enters the feeding mechanism from the output end of the die-cutting machine. The conveyor belt of the feeding mechanism absorbs the die-cut cardboard. The lower ejector pin in the lower label removal mechanism lifts the finished cardboard upward, and the upper ejector pin in the upper label removal mechanism presses down on the waste edge, so as to achieve precise separation of the finished cardboard from the waste edge. The structure of the lower label removal mechanism is similar to that disclosed in the patent with application number CN202520157152.6, and will not be elaborated further.

[0051] The waste edges detached from the finished cardboard are conveyed to the waste collection vehicle by the conveyor belt, while the finished cardboard is simultaneously adsorbed by the transfer arm when it is pushed up by the lower ejector pin and transferred to the palletizing mechanism by the conveyor belt. The gear is driven by the label removal power component to rotate the rotating shaft and the air direction switching disk, so that the docking hole of the air direction switching disk rotates to coincide with the connecting hole in sequence, and the equipment switches to the suction mode, and the transfer arm adsorbs the finished cardboard. When the finished cardboard is transferred to the top of the palletizing mechanism, the air direction switching disk rotates to the blocking part to block the connecting hole, the solenoid valve controls the blower to start, and the equipment switches to the blowing mode. The conveyor belt blows the finished cardboard into the interior of the palletizing mechanism. The palletizing mechanism is a conventional technology and will not be elaborated further.

[0052] Finished paperboards are stacked layer by layer in the palletizing mechanism. The detection module of the labeling mechanism monitors the number of finished paperboards stacked in the palletizing mechanism in real time. When the detection module detects that the number of finished paperboards in the palletizing mechanism has reached the set value, the labeling mechanism starts the grouping operation. The top label power component drives the top label block to rise, pass through the top label window at the bottom of the paper storage seat, and push the labeling paperboard in the paper storage seat upward. The label suction arm picks up the labeling paperboard and inserts it into the palletizing mechanism under the drive of the labeling power component, thus realizing the grouping.
