Description

Technical Field

[0001] The invention relates to the technical field of plastic cup production and conveying, and in particular to a plastic cup production and conveying device with an automatic stacking mechanism. Background Art

[0002] With the continued prosperity of the plastic products industry, the market demand for plastic cups, as containers widely used in daily life, has shown a steady growth trend. Consumers' quality requirements for plastic cups are also increasing. They not only pay attention to the integrity and flawlessness of the cups' appearance, but also have strict standards for their cleanliness. In a large-scale production environment, the traditional production, transportation and stacking methods of plastic cups have gradually exposed many drawbacks. Manual operation is difficult to meet the rhythm of efficient production, and human factors are likely to cause unstable product quality in the feeding, inspection, stacking and other links.

[0003] The existing plastic cup conveying equipment has obvious deficiencies in terms of automation and functional integration. Although some equipment has simple conveying functions, it lacks effective guarantees for feeding stability. It is often just a single mechanical push or grab method, which is difficult to adapt to plastic cups of different shapes and sizes, and it is easy to cause the cups to shake, deflect or even slip during the conveying process. In the pretreatment stage, the dust cleaning is not thorough enough, and the residual dust may affect the appearance of the product and the safety of subsequent use; defect inspection mostly relies on manual visual inspection, which is inefficient and has a high misjudgment rate, resulting in an increased risk of unqualified products entering the market. In terms of stacking, the stacking structure of most equipment is relatively fixed and cannot be flexibly adjusted to adapt to the quantity and stacking requirements of different production orders. In addition, the positioning and clamping of the cups during the stacking process are not accurate enough, which is prone to stacking skew, collapse, etc., which seriously restricts the overall quality and efficiency of plastic cup production.

[0004] For this reason, there is an urgent need for a conveying device for producing plastic cups with an automatic stacking mechanism. Summary of the invention

[0015] Furthermore, a conveying method of a conveying device for producing plastic cups with an automatic stacking mechanism comprises the following steps:

[0016] Step 1: The plastic cup is sent to one side of the rotating frame with the bottom facing the rotating frame through the feeding frame, and then the bottom of the plastic cup is adsorbed by the adsorption frame located on the side of the feeding frame, and the adsorption frame is controlled by the driving end of the servo electric cylinder 1 to approach the bottom of the plastic cup on the top of the feeding frame, and the adsorption head on one side of the adsorption frame is used to adsorb the bottom of the plastic cup, and the clamping blocks inside the grooves are turned outward, and the outer peripheral surface of the plastic cup is adsorbed and clamped for positioning by the clamping blocks;

[0017] Step 2: After the plastic cup is adsorbed, clamped and positioned by the adsorption rack and the adsorption head, the rotating rack is controlled to rotate, and the plastic cup is transferred to the bottom of the cleaning chamber. The two movable closing plates at the bottom of the cleaning chamber are controlled to slide to both sides, and then the driving end of the servo electric cylinder 1 is used to control the adsorption rack to move into the cleaning chamber. After the plastic cup is sent into the cleaning chamber, the bottom of the cleaning chamber is closed by the two movable closing plates. At this time, the output shaft of the rotating motor is controlled to drive the cleaning rack to rotate, and the inside and surface of the plastic cup are cleaned by the cleaning soft hairs arranged at the bottom of the cleaning rack, and the dust cleaned from the surface of the plastic cup is sucked together with the dust suction port inside the cleaning rack;

[0018] Step 3: After the surface of the plastic cup is cleaned, the rotating frame is controlled to rotate, and the plastic cup after the surface cleaning is sent into the inspection chamber. The driving end of the micro-electric cylinder is used to control the industrial camera to move inside the plastic cup. The surface defects of the plastic cup are automatically inspected by the industrial camera. The surface image of the plastic cup is obtained by the industrial camera, and the collected surface image of the plastic cup is compared with the image of the plastic cup required by the process. The plastic cup whose surface image does not meet the process requirements is determined as a defective product;

[0019] Step 4. When the plastic cups are automatically stacked, the plastic cups that have completed the dust cleaning process and meet the defect inspection standards are driven by the rotating frame to rotate to one side of the stacking frame, and the driving end of the servo electric cylinder 2 is used to control the adjustment plate to move outward on one side of the stacking frame, so as to adjust the volume of the stacking material chamber inside the stacking frame. When the plastic cups are stacked inside the stacking material chamber, the electric slide is first used to drive the stacking frame to slide toward the front, so that the rear side of the stacking material chamber is located directly below the adsorption frame. Then, the driving end of the servo electric cylinder 1 is used to control the plastic cups that are adsorbed and clamped on one side of the adsorption frame and pushed into the stacking material chamber. The plastic cups are placed into the stacking material chamber from back to front in sequence through the adsorption frame on the rotating frame, and the bottom of the lowest plastic cup is adsorbed and positioned in conjunction with the adsorption holes at the bottom of the inner wall of the stacking material chamber. The driving end of the servo electric cylinder 2 controls the adjustment plate to approach the surface of the plastic cup, and the adjustment plate is used to clamp and position the plastic cups stacked inside the stacking material chamber.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] 1. In the present invention, the feeding rack can automatically feed the molded plastic cups to the left side of the conveyor rack, the rotating rack in the feeding assembly rotates driven by the driving motor, and the servo electric cylinder in the mounting groove drives the adsorption rack, and the adsorption head is used to adsorb the bottom surface of the plastic cup, and the clamping block in the groove can adsorb and clamp the outer peripheral surface of the plastic cup for positioning, which effectively improves the stability of the plastic cup during the feeding process, and no manual assistance is required throughout the process, which greatly improves the conveying and processing efficiency. In addition, the surface cleaning treatment and surface defect inspection carried out in the processing rack can ensure product quality, and the plastic cups that fail the defect inspection are automatically rejected by the discharging rack. Finally, the processed plastic cups are automatically stacked by the stacking assembly, realizing automated, continuous and efficient stacking operations, which not only improves the stacking stability and efficiency, but also plays a role in stabilizing the conveying, facilitates the subsequent packaging of the plastic cups, and improves the overall automation level of plastic cup production and transportation and the product quality control level.

[0022] 2. In the present invention, a cleaning frame is driven to rotate by a rotating motor, and the cleaning soft bristles at the bottom of the cleaning frame can effectively clean the inside and surface of the plastic cup. At the same time, the dust suction port can absorb the cleaned dust in time, and realize automatic and relatively thorough cleaning operations in a closed cleaning chamber environment, thereby ensuring the surface cleanliness of the plastic cup and improving the overall quality of the product; then a micro electric cylinder is used to drive the industrial camera to move inside the plastic cup, and with the help of annular light sources around the inspection chamber, the industrial camera can accurately obtain the surface image of the plastic cup and compare it with the image required by the process, thereby automatically inspecting surface defects and accurately determining unqualified products. This helps to strictly control the quality of the plastic cup, avoid defective products from flowing into subsequent processes, reduce errors and costs of manual inspections, and improve the efficiency and accuracy of quality inspections in the production process, thereby ensuring the efficient and stable operation of the entire plastic cup production and transportation process.

[0023] 3. In the present invention, the top of the conveyor belt is connected to the mounting base through a connecting block by means of a card slot, a card block, an electromagnet and a metal attraction sheet to achieve adsorption and engagement. This connection method is convenient for the installation and disassembly of the mounting base and can ensure the stability of the connection. The electric slide on the mounting base cooperates with the stacking frame, and the position of the stacking frame can be flexibly adjusted to facilitate its accurate reception of plastic cups that have been cleaned and inspected for defects. In addition, the stacking frame internally drives the adjustment plate through the servo electric cylinder to flexibly adjust the volume of the stacking cavity, which can meet the stacking requirements of different numbers of plastic cups. During the actual stacking operation, the bottom of the lowest plastic cup is adsorbed and positioned by the adsorption hole, and then the plastic cup in the stacking cavity is clamped and positioned in combination with the adjustment plate, which ensures the stability of the plastic cup during the stacking process from multiple dimensions, so that the plastic cups can be placed in the stacking cavity in an orderly manner from back to front, greatly improving the stability and accuracy of the automatic stacking of plastic cups, and laying a good foundation for the subsequent transportation of plastic cups and the smooth development of subsequent processes.
