Abstract
Description
Technical Field
[0001] This utility model relates to a sheet feeding device for conveying and picking up sheets in a fixed direction, such as the lid of a packaging box (flat type, not folded), and belongs to the field of packaging machinery technology (but is not limited to the field of packaging machinery technology). Background Technology
[0002] The large-scale use of packaging machinery has greatly improved production efficiency and product quality while reducing labor costs. With technological advancements, packaging machinery is becoming increasingly automated, and the automatic supply of packaging materials is one of the key aspects of achieving efficient and precise packaging. Utility Model Content
[0003] The purpose of this invention is to provide a sheet feeding device that enables automatic feeding and gripping.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows:
[0005] A sheet feeding device includes a conveyor belt that rotates forward under the drive of a front power component. A slide rail is provided along the edge of the conveyor belt, and a slider is mounted on the slide rail. A rear pusher plate extending towards the conveyor belt is mounted on the slider, and a rear pusher component is connected to the slider, which pushes the slider forward along the slide rail. A column is provided at the front end of the slide rail, and a front blocking plate is mounted on the column. Sheets are stacked vertically on the conveyor belt, with the stacked sheets located between the front blocking plate and the rear pusher plate. A picking component is provided above the conveyor belt at its front end. The rear end of the picking component is rotatably mounted, and the front end of the picking component is provided with several suction cup assemblies (including suction cups and a vacuum generator). A picking power component is connected to the picking component, which drives the picking component to swing.
[0006] Driven by the picking power unit, the picking component moves downwards. The suction cups on the picking component then pick up the foremost sheet of the stacked sheets. Driven upwards by the picking power unit, the picked-up sheet breaks free from the front stop plate and detaches from the stacked sheets, where it is picked up. With one sheet picked up, a "vacancy" is created. At this point, the conveyor belt rotates forward under the drive of the front power unit, and the rear pushing force unit pushes the stacked sheets forward to fill the "vacancy." This process continues, achieving continuous supply and picking.
[0007] In one embodiment, there are two conveyor belts, and the sheet is laid on both sides of the two conveyor belts.
[0008] As an implementation manner, the front power component includes a one-way runner, the one-way runner serves as the driving wheel of the conveyor belt, the one-way runner is connected to the front cylinder, and the front cylinder drives the one-way runner to rotate unidirectionally.
[0009] As an implementation manner, the rear driving force component is a spring balancer, the spring balancer is installed at the front end of the conveyor belt, and the pulling rope of the spring balancer is connected to the slider. Further, between the spring balancer and the slider, a guiding wheel through which the pulling rope passes is provided on the slide rail.
[0010] As an implementation manner, the rear end of the picking component is rotatably installed through a rotating shaft.
[0011] As an implementation manner, the picking power component is a cylinder.
[0012] The utility model can continuously provide the materials required for the packaging process, reduce the downtime, and improve the efficiency of the overall production line. By precisely controlling the supply quantity and speed, it helps to maintain consistent packaging quality and specifications and reduce the errors caused by human factors. The automatic supply reduces the demand for manpower and the labor cost; at the same time, it also reduces the waste. Brief Description of the Drawings
[0013] The following further describes the utility model in detail in conjunction with the drawings and specific implementation manners.
[0014] Figure 1 It is a three-dimensional view of the sheet feeding device.
[0015] Figure 2 It is a side view of the sheet feeding device. Specific Implementation Manner
[0016] As shown in Figure 1 、 2 The sheet feeding device includes a conveyor belt 1. The conveyor belt 1 can be a wider one or two narrower ones. At this time, both sides of the sheet are placed on the two conveyor belts 1.
[0017] The conveyor belt 1 has a driving wheel and a driven wheel. The driving wheel is driven to rotate forward. The driving wheel is a one-way runner 2. The one-way runner 2 is connected to the front cylinder 3. The front cylinder 3 drives the one-way runner 2 to rotate unidirectionally. When the piston rod of the front cylinder 3 retracts, the one-way runner 2 does not rotate back. Of course, the driving wheel is not limited to this, and it can be completely driven by components in the prior art, such as an electric roller, etc.
[0018] A slide rail 4 is provided along one side of the conveyor belt 1, and a slider 5 is provided on the slide rail 4. A rear pusher plate 6 extending towards the conveyor belt 1 is installed on the slider 5, and a rear pushing force component is connected to the slider 5. The rear pushing force component pushes the slider 5 forward along the slide rail 4. Specifically, the rear pushing force component is a spring balancer 9, which is installed at the front end of the conveyor belt 1, such as on a column 7. The pull rope 10 of the spring balancer 9 is connected to the slider 5. Between the spring balancer 9 and the slider 5, a guide wheel 11 is provided on the slide rail 4 through which the pull rope 10 passes.
[0019] A column 7 is provided at the front end of the slide rail 4, and a front blocking plate 8 (smaller, otherwise it would be difficult to remove the sheet) is installed on the column 7. The sheet (such as an unfolded box lid) is stacked vertically on the conveyor belt 1, and the stacked sheet is located between the front blocking plate 8 and the rear push plate 6.
[0020] At the front end of the conveyor belt 1, above the conveyor belt 1, a picking component is provided. The picking component includes a swing rod 12. The rear end of the swing rod 12 is rotatably mounted on a bracket via a rotating shaft 13. The front end of the swing rod 12 is provided with two crossbars 14. Two suction cup assemblies 15 are provided on the crossbars 14. The suction cup assembly 15 includes a suction cup and a vacuum generator. The vacuum generator generates negative pressure, enabling the suction cup to firmly adhere to the item. A cylinder 16 is connected to the middle of the swing rod 12. The cylinder 16 drives the swing rod 12 to swing along the rotating shaft 13.
[0021] In operation, the picking component moves downward under the drive of cylinder 16. The suction cup assembly 15 on the picking component picks up the foremost sheet of the stacked sheets. The swing rod 12 moves upward under the drive of cylinder 16, and the picked-up sheet breaks free from the restraint of the front blocking plate 8, detaches from the stacked sheets, and is picked up. Since one sheet is picked up, a "vacancy" is left. At this time, the conveyor belt 1 is pushed forward by the front cylinder 3, and the one-way rotating wheel 2 (drive wheel) rotates forward. The pull rope 10 of the spring balancer 9 pushes the stacked sheets forward through the slider 5 and the rear push plate 6 to fill the "vacancy". This process is repeated to achieve continuous supply and picking.
[0022] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
