Description

Technical Field

[0001] This utility model relates to the technical field of workpiece conveying devices applied to corner attaching machines, and in particular to a workpiece conveying device applied to corner attaching machines. Background Technology

[0002] In today's society, with the significant increase in the use of product packaging, such as wine boxes, shoe boxes, and gift boxes, the requirements for the quality of packaging box covers have become increasingly stringent.

[0003] The original technology, which relied entirely on manual production, could no longer meet the large-scale demand for products. Furthermore, with the ever-increasing labor costs, continuing to use the original manual production method would greatly increase the production volume of finished products.

[0004] In order to free cardboard boxes from traditional manual labor, most factories have begun to use corner-attaching machines to replace manual labor.

[0005] However, existing corner-attaching machines are not fully automated throughout the entire process. The material is still conveyed manually, meaning that people manually pick up the material and then convey it to the processing area, which greatly affects processing efficiency.

[0006] Therefore, in this utility model patent application, the applicant has carefully researched a workpiece conveying device for use in corner attaching machines to solve the above problems. Utility Model Content

[0007] The present invention addresses the shortcomings of the prior art by providing a workpiece conveying device for a corner-attaching machine. This device ensures that the workpiece is always supported by the pallet and conveyor belt before the subsequent corner-attaching mechanism performs its pressing action, thus preventing defective products due to lack of support caused by corner-attaching mechanism malfunction and improving production quality.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A workpiece conveying device for use in a corner pasting machine, which is used to convey the workpiece to the corner pasting processing area, includes two conveying mechanisms arranged at relative intervals.

[0010] Each conveying mechanism includes a conveyor belt mechanism for carrying and conveying the workpiece to be processed, a pallet with a folded edge parallel to the direction of movement of the conveyor belt mechanism for carrying the workpiece to be processed, and a drive unit for driving the conveyor belt mechanism and the pallet to move inward or outward simultaneously.

[0011] The conveyor belt mechanism includes a conveyor belt, a pallet located on the outer side of the conveyor belt, and a horizontal extension portion extending inward from the inner end face of the pallet. The horizontal extension portion extends into the interior of the conveyor belt, and the upper end face of the conveyor belt is higher than the upper end face of the pallet.

[0012] The drive unit drives the connecting conveyor belt mechanism and the pallet to drive the inner end faces of both the conveyor belt and the horizontal extension to be simultaneously located inside and outside the adjacent fold lines of two fold lines parallel to the direction of movement of the workpiece.

[0013] As a preferred embodiment, it also includes a size adjustment drive unit for driving one of the conveying mechanisms to move closer to or further away from the other conveying mechanism to accommodate workpieces of different widths. The drive unit includes a first driving wheel, a flexible rotary belt, two first driven wheels, two lead screws, a first slide rail extending along the direction of movement of the conveying mechanism, a first slider slidably mounted on the first slide rail, and a rotary motor for driving the first driving wheel.

[0014] Each lead screw is coaxially provided with a second driven wheel that can rotate synchronously with the lead screw, and a movable plate is threadedly connected to the surface of each lead screw, the movable plate being connected to the first slider;

[0015] The inner ring of the rotary belt contacts the first driving pulley and the two second driven pulleys, and the outer ring of the rotary belt contacts the two first driven pulleys. The first driving pulley is located between the two first driven pulleys and the height of the first driving pulley is greater than the height of the two first driven pulleys. The height of the two second driven pulleys is lower than the height of the two first driven pulleys, and the distance between the two first driven pulleys is less than the distance between the two second driven pulleys.

[0016] The conveyor belt mechanism is connected to two moving plates respectively so that it moves with the corresponding moving plates.

[0017] As a preferred embodiment, the conveyor belt mechanism further includes a second drive wheel, a third transmission wheel, and a drive motor. The conveyor belt is fitted onto the second drive wheel and the third transmission wheel, and the output shaft of the drive motor is connected to the second drive wheel.

[0018] As a preferred embodiment, the conveyor belt mechanism is connected to the pallet.

[0019] As a preferred embodiment, the drive unit includes a second slide rail extending in a left-right direction, a second slider slidably mounted on the second slide rail, and a drive cylinder for simultaneously adjusting the conveyor belt mechanism and the pallet to move closer to or further away from the workpiece. Both the conveyor belt mechanism and the pallet are mounted on the second slider, and the drive cylinder drives the second slider to reciprocate along the second slide rail.

[0020] As a preferred embodiment, each conveying mechanism is also provided with a blocking mechanism for limiting the left and right folding edges of the workpiece to accommodate workpieces of different thicknesses. The blocking mechanism includes a blocking component and a blocking component driving unit for driving the blocking component to move closer to or away from the left and right outward sides of the workpiece.

[0021] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly uses a pallet located on the outside of the conveyor belt with the upper surface of the conveyor belt higher than the upper surface of the pallet. This ensures that the workpiece to be processed is always supported by the pallet and the conveyor belt before the subsequent corner-pressing mechanism performs its pressing action, thus avoiding defective products due to lack of support caused by a failure of the corner-pressing mechanism and improving production quality.

[0022] Secondly, with the cooperation of the size adjustment drive unit, it can be used for workpieces of different widths, which is quite flexible;

[0023] Furthermore, the shielding mechanism can block the left and right folds of the workpiece, which can accommodate workpieces of different thicknesses and ensure the stability and reliability of the workpiece during the conveying process.

[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0059] like Figures 1 to 8As shown, a workpiece conveying device for a corner-attaching machine is used to convey the workpiece 60 to the corner-attaching processing area. It includes a frame 10 and two conveying mechanisms 100 disposed on the frame 10 and spaced apart from each other.

[0060] Each conveying mechanism 100 includes a conveyor belt mechanism 20 for carrying and conveying a workpiece 60 to be processed, a folded plate 30 with a folded edge parallel to the direction of movement of the conveyor belt mechanism 20 for carrying the workpiece 60 to be processed, and a drive unit 50 for driving the conveyor belt mechanism 20 and the plate 30 to move inward or outward simultaneously.

[0061] In this embodiment, the conveyor belt mechanism 20 includes a conveyor belt 21, a second drive wheel 22, a third transmission wheel 23, and a drive motor 24. The conveyor belt 21 is sleeved on the second drive wheel 22 and the third transmission wheel 33, and the output shaft of the drive motor 24 is connected to the second drive wheel 22.

[0062] The pallet 30 is located beside the conveyor belt 21. The inner end face of the pallet 30 extends horizontally inward to form a horizontal extension portion 32. The horizontal extension portion 32 extends into the interior of the conveyor belt 21. The upper end face of the conveyor belt 21 is higher than the upper end face of the pallet 30.

[0063] The drive unit 50 drives the connecting conveyor belt mechanism 20 and the pallet 30 to drive the inner end faces of both the conveyor belt 21 and the horizontal extension to be simultaneously located inside and outside of adjacent fold lines 61 of two fold lines 61 parallel to the direction of movement of the workpiece 60.

[0064] The drive unit 50 includes a second slide rail 51 extending in the left-right direction, a second slider 52 slidably mounted on the second slide rail 51, and a drive cylinder 53 for simultaneously adjusting the conveyor belt mechanism 20 and the pallet 30 to move closer to or further away from the workpiece. The conveyor belt mechanism 20 and the pallet 30 are both mounted on the second slider 52. The drive cylinder 53 drives the second slider 52 to reciprocate along the second slide rail 51.

[0065] Each conveying mechanism is also equipped with a blocking mechanism 70 for limiting the left and right folded edges 62 of the workpiece 60 to accommodate workpieces of different thicknesses. The blocking mechanism 70 includes a blocking member 71 and a blocking member driving unit 72 for driving the blocking member 71 to move closer to or away from the left and right outward sides of the workpiece 60. The blocking member 71 is located above the pallet 30 and the conveyor belt 21.

[0066] In this embodiment, the conveyor belt mechanism 20 is connected to the pallet 30. A mounting block 31 is connected to the lower end face of the pallet 30, and the third transmission wheel 23 is rotatably connected to the mounting block 31. The drive motor 24 is mounted on the lower end face of the pallet 30. The pallet 30 is connected to the second slider 52.

[0067] It also includes a size adjustment drive unit 40 for driving one of the conveying mechanisms to move closer to or away from the other conveying mechanism to accommodate workpieces of different widths, and a size adjustment drive unit 40a for driving the other conveying mechanism to move closer to or away from one of the conveying mechanisms to accommodate workpieces of different widths.

[0068] In this embodiment, two conveying mechanisms 100 are symmetrically spaced on the frame 10. Size adjustment drive unit 40 drives the right-side conveying mechanism to move closer to the left or further away from the left-side conveying mechanism, and size adjustment drive unit 40a drives the left-side conveying mechanism to move closer to the right or further away from the right-side conveying mechanism. Size adjustment drive units 40 and 40a have identical structures and can be controlled by an external controller to achieve synchronized operation. The specific structure of size adjustment drive unit 40 will be described below using it as an example.

[0069] The size adjustment drive unit 40 includes a first drive wheel 41, an inverted T-shaped bracket 43, a flexible rotary belt 44, two first driven wheels 45, two lead screws 46, a first slide rail 401 extending along the movement direction of the transmission mechanism 100, a first slider 402 slidably mounted on the first slide rail 401, and a rotary motor 47 for driving the first drive wheel 41.

[0070] The inverted T-shaped bracket 43 is mounted on the frame 10 and includes an outer plate 431 extending along the movement direction of the workpiece 60 and an upright plate 432. The upright plate 432 is connected to the middle section of the outer plate 431. One end of each lead screw 46 is rotatably connected to the outer plate 431. The rotary motor 47 is mounted on the upright plate 432. The upright plate 432 has a through hole 433. The output shaft of the rotary motor 47 passes through the through hole 433 and drives the first driving wheel 41. Two first driven wheels 45 are rotatably connected to the outer plate 431.

[0071] Each lead screw 46 is coaxially provided with a second driven wheel 48 that can rotate synchronously with the lead screw 46, and a moving plate 461 is threadedly connected to the surface of each lead screw 46. The moving plate 461 is connected to the first slider 402.

[0072] The inner ring of the rotary belt 44 contacts the first driving wheel 41 and the two second driven wheels 48, and the outer ring of the rotary belt 44 contacts the two first driven wheels 45. The first driving wheel 41 is located between the two first driven wheels 45 and the height of the first driving wheel 41 is greater than the height of the two first driven wheels 45. The height of the two second driven wheels 48 is lower than the height of the two first driven wheels 45, and the distance between the two first driven wheels 45 is less than the distance between the two second driven wheels 48. The conveyor belt mechanism 20 is connected to two moving plates 461 respectively to move with the corresponding moving plates 461.

[0073] In this embodiment, the movable plate 461 is connected to the second slide rail 51. A rotary motor 47 drives the first driving wheel 41 to rotate. The first driving wheel 41 drives the second driven wheel 48 to rotate via a rotary belt 44. The second driven wheel 48 drives the lead screw 46 to rotate. The lead screw 46 drives the movable plate 461 to move, which in turn drives the blocking mechanism 70, the conveyor belt mechanism 20, and the support plate 30 to move. Preferably, the two movable plates 461 are connected to the second slide rail 51 via a bracket.

[0074] The bracket is a U-shaped bracket 49 with its opening facing upwards. The U-shaped bracket 49 includes a base plate 491 and a front side plate 492 and a rear side plate 493 that are respectively connected to the front and rear ends of the base plate 491. The front side plate 492 is connected to a movable plate, and the rear side plate 493 is connected to another movable plate 461.

[0075] The drive unit 50 also includes a crossbeam 54 extending in the front-rear direction. The front and rear ends of the crossbeam 54 are respectively connected to the upper surfaces of the front side plate 492 and the rear side plate 493. The drive cylinder 53 is disposed on the crossbeam 54.

[0076] The shielding component driving unit 72 includes a motor base 721 mounted on a U-shaped bracket 49, a telescopic motor 722 fixed on the motor base, a screw sleeve 723 connected to the shielding component 71, and a screw 724 passing through the screw sleeve 723 and driven to rotate by the telescopic motor 722. When the screw 724 rotates, it drives the screw sleeve 723 to move left and right.

[0077] In this embodiment, two first slide rails 401 and two first sliders 402 are provided, and each first slider 402 is adapted to one first slide rail 401. The two first slide rails 401 are symmetrically spaced front to back, and the two first sliders 402 are both provided on the lower end surface of the base plate 491 and are symmetrically spaced front to back.

[0078] When the rotary motor 47 is activated, it drives the lead screw 46 to rotate sequentially through the first driving wheel 41, the rotary belt 44, and the second driven wheel 48. This drives the moving plate 461 to move along the first slide rail 401, thereby moving the U-shaped bracket 49, the conveyor belt mechanism 20, the pallet 30, the drive unit 50, and the blocking mechanism 70.

[0079] The key design feature of this utility model is that the pallet is located on the outside side of the conveyor belt and the upper surface of the conveyor belt is higher than the upper surface of the pallet. This ensures that the workpiece to be processed is always supported by the pallet and the conveyor belt before the subsequent corner-pressing mechanism performs the pressing action. This avoids defective products due to lack of support caused by a failure of the corner-pressing mechanism, thereby improving production quality.

[0080] Secondly, with the cooperation of the size adjustment drive unit, it can be used for workpieces of different widths, which is quite flexible;

[0081] Furthermore, the shielding mechanism can block the left and right folds of the workpiece, which can accommodate workpieces of different thicknesses and ensure the stability and reliability of the workpiece during the conveying process.

[0082] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
