Description

Technical Field

[0001] The present invention relates to a sheet material feeding device for conveying and taking sheets in a fixed direction, such as the lid of a packaging box (flat and not folded), belonging to the technical field of packaging machinery (but not limited to the technical field of packaging machinery). Background Art

[0002] The large-scale use of packaging machinery has greatly improved production efficiency and product quality, while reducing labor costs. With the development of technology, the degree of automation of packaging machinery is becoming increasingly higher. The automatic supply of packaging materials is one of the key links to achieve efficient and accurate packaging. Summary of the Invention

[0003] The object of the present invention is to provide a sheet material feeding device that can realize automatic feeding and grabbing.

[0004] To achieve the above object, the technical solution of the present invention is:

[0005] The sheet feeding device includes a conveyor belt, which rotates forward under the drive of the front power component, a slide rail is provided on the edge of the conveyor belt, a slider is provided on the slide rail, a rear pushing plate extending to the conveyor belt is installed on the slider, and a rear pushing force component is connected to the slider, and the rear pushing force component pushes the slider forward along the slide rail; a column is provided at the front end of the slide rail, and a front blocking piece is installed on the column, and the stacked sheets are placed vertically on the conveyor belt, and the stacked sheets are located between the front blocking piece and the rear pushing plate; a picking component is provided above the conveyor belt at the front end of the conveyor belt, and the rear end of the picking component can be rotatably installed, and a number of suction cup assemblies (including suction cups and vacuum generators) are provided at the front end of the picking component, and a picking power component is connected to the picking component, and the picking power component drives the picking component to swing.

[0006] Driven by the pickup power unit, the pickup unit moves downward. The suction cup of the suction cup assembly on the pickup unit attracts the front sheet in the stack. Driven by the pickup power unit, the pickup unit moves upward. The attracted sheet breaks free from the restraints of the front barrier sheet and detaches from the stack, allowing it to be grabbed by the pickup unit. As a sheet is grabbed, a "space" is left. At this point, the conveyor belt rotates forward, driven by the front power unit, and the rear propulsion unit pushes the stack forward to fill the "space." This process continues in this manner, achieving continuous supply and grabbing.

[0007] As an embodiment, there are two conveyor belts, and both sides of the sheet are placed on the two conveyor belts.

[0008] As an implementation manner, the front power component includes a one-way rotating wheel, which serves as the driving wheel of the conveyor belt. The one-way rotating wheel is connected to the front cylinder, and the front cylinder drives the one-way rotating wheel 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 guide 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 present invention 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 waste. Description of the Drawings

[0013] The present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0014] Figure 1 It is a perspective 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 and 2 , the sheet feeding device includes a conveyor belt 1. The conveyor belt 1 can be a wider one or two narrower ones. In this case, 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 rotating wheel 2. The one-way rotating wheel 2 is connected to the front cylinder 3. The front cylinder 3 drives the one-way rotating wheel 2 to rotate unidirectionally. When the piston rod of the front cylinder 3 retracts, the one-way rotating wheel 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 arranged on one side of the conveyor belt 1. A slider 5 is arranged on the slide rail 4. A rear push plate 6 extending towards the conveyor belt 1 is installed on the slider 5. A rear driving force component is connected to the slider 5, and the rear driving force component pushes the slider 5 forward along the slide rail 4. Specifically, the rear driving force component is a spring balancer 9. The spring balancer 9 is installed at the front end of the conveyor belt 1, such as on a column 7. A pulling rope 10 of the spring balancer 9 is connected to the slider 5. A guide wheel 11 through which the pulling rope 10 passes is arranged on the slide rail 4 between the spring balancer 9 and the slider 5.

[0019] A column 7 is arranged at the front end of the slide rail 4. A front blocking piece 8 (relatively small, otherwise it is not conducive to taking out the sheet material) is installed on the column 7. The sheet materials (such as the un-folded box lids) are stacked vertically on the conveyor belt 1, and the stacked sheet materials are located between the front blocking piece 8 and the rear push plate 6.

[0020] At the front end of the conveyor belt 1, a picking component is arranged above the conveyor belt 1. The picking component includes a swing rod 12. The rear end of the swing rod 12 is rotatably installed on a bracket through a rotating shaft 13. Two cross bars 14 are arranged at the front end of the swing rod 12. Two suction cup assemblies 15 are arranged on the cross bars 14. The suction cup assembly 15 includes a suction cup and a vacuum generator. The vacuum generator generates negative pressure so that the suction cup can firmly adsorb the article. A cylinder 16 is connected to the middle of the swing rod 12, and the cylinder 16 drives the swing rod 12 to swing along the rotating shaft 13.

[0021] During use, the picking component moves downward under the drive of the cylinder 16. The suction cup of the suction cup assembly 15 on the picking component adsorbs the frontmost sheet material of the stacked sheet materials. The swing rod 12 moves upward under the drive of the cylinder 16. The adsorbed sheet material breaks free from the restraint of the front blocking piece 8 and separates from the stacked sheet materials and is grabbed. Since one sheet material is grabbed, leaving a "space", at this time, the conveyor belt 1 moves forward under the push of the front cylinder 3, and the driving wheel 2 (the driving wheel) rotates forward. The pulling rope 10 of the spring balancer 9 pushes the stacked sheet materials forward through the slider 5 and the rear push plate 6 to fill the "space". And so on, continuous supply and picking are realized.

[0022] The above embodiments do not limit the present invention in any way. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
