Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and more specifically, relates to a box-removing device. Background Technology

[0002] In automatic cartoning machines, a carton-removing device is essential, which can remove the packaging boxes from the storage rack and place them on the packaging box conveyor.

[0003] Patent CN202120637798.6 discloses a box-picking device for a pastry packaging machine, including a frame with a storage bin for easy stacking of packaging boxes. The side of the storage bin is a discharge port. The frame is provided with a first hinge shaft and a second hinge shaft. One end of a swing arm is connected to the first hinge shaft. The second hinge shaft is positioned higher than the first hinge shaft. A guide arm is hinged to the second hinge shaft. A guide sleeve is provided on the guide arm. A guide shaft is slidably installed inside the guide sleeve. One end of the guide shaft passes through the guide sleeve, and the other end is hinged to the other end of the swing arm via a movable shaft. The guide shaft and the swing arm intersect at an obtuse angle. A suction cup assembly for picking up packaging boxes from the storage bin is installed on the movable shaft. A reciprocating swing drive device is installed on the frame to drive the swing arm to reciprocate between a box-picking station and a box-placing station.

[0004] The aforementioned box-retrieving device uses a swing arm to move the movable shaft and relies on a guide shaft to adjust the orientation of the suction cup assembly on the movable shaft, so that the suction cup assembly can pick up the packaging box and place it in the designated position. However, in this structure, it is necessary to rely on the guide shaft to adjust the orientation of the suction cup assembly on the movable shaft. Under high-speed operation, the sliding speed between the guide shaft and the guide sleeve is fast and the frequency is high, which makes the guide sleeve very easy to wear and also easy to get stuck.

[0024] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] The following disclosure provides many different implementation methods or examples for different ways of implementing this utility model.

[0026] Reference Figures 1 to 5 As shown, in one embodiment of the present invention, a box-retrieving device includes a frame 1, a drive module 2, a rotating shaft 3 and an auxiliary shaft 4 on the frame 1. The drive module 2 is used to drive the rotating shaft 3 to rotate. The axis of the auxiliary shaft 4 is parallel to the axis of the rotating shaft 3 and is higher than the rotating shaft 3. A first swing arm 5 is fixed on the rotating shaft 3. A second swing arm 6 is rotatably mounted on the auxiliary shaft 4. A third swing arm 7 is rotatably mounted on the second swing arm 6. An installation rod 8 is fixed on the third swing arm 7 and is rotatably connected to the first swing arm 5. An adsorption module 9 for absorbing the packaging box is provided on the installation rod 8.

[0027] The drive module 2 drives the rotating shaft 3 to rotate, which in turn causes the first swing arm 5 to swing. The first swing arm 5 drives the mounting rod 8 to move, thereby moving the third swing arm 7. Since the second swing arm 6 is connected to the third swing arm 7, the second swing arm 6 will also swing. Both the first swing arm 5 and the second swing arm 6 swing around a fixed axis. Therefore, the posture of the second swing arm 6 can be changed under the constraints of the first swing arm 5 and the second swing arm 6. The mounting rod 8 is fixed on the second swing arm 6. Therefore, the mounting rod 8 rotates under the drive of the second swing arm 6, thereby changing the orientation of the adsorption module 9. When the mounting rod 8 is in the upper position, the adsorption module 9 can adsorb the packaging boxes in the storage rack. When the mounting rod 8 is in the lower position, the adsorption module 9 has flipped over and can place the packaging boxes in the designated position.

[0028] In this embodiment, the drive module 2 is generally a motor and a reduction mechanism. The reduction mechanism connects the output shaft and the rotating shaft of the motor, thereby allowing the motor to drive the rotating shaft 3 to reciprocate.

[0029] In this embodiment, the mounting rod 8 passes through the third swing arm 7 and is rotatably connected to the first swing arm 5. In this way, the first swing arm 5 and the second swing arm 6 can be aligned, making the structure more compact.

[0030] In this embodiment, the adsorption module 9 includes a mounting block 91 and a suction cup assembly 92 disposed on the mounting block 91. The mounting rod 8 has a mounting section 81, and the outer contour of the mounting section 81 in the cross section perpendicular to its length direction is rectangular. The mounting block 91 is provided with a rectangular through hole 911, and the mounting section 81 passes through the rectangular through hole 911. The mounting block 91 is provided with a first threaded hole, which communicates with the rectangular through hole 911. A screw handle 912 is threadedly connected to the first threaded hole, and the mounting block 91 is fixed to the mounting section 81 by the screw handle 912.

[0031] By setting the mounting section 81 into a rectangle and using the rectangular through hole 911, the position of the mounting block 91 can be accurately positioned, thereby determining the position of the suction cup assembly 92. This prevents the mounting block 91 from rotating during operation, which could cause the suction cup assembly 92 to fail to adhere properly. Furthermore, by using the screw handle 912 for fixing, the position of the mounting block 91 on the mounting section 81 can be changed according to the actual situation, thereby adjusting the position of the suction cup assembly 92, which is more flexible.

[0032] Preferably, the outer contour of the installation segment 81 in the cross-section perpendicular to its length direction is a rounded rectangle with rounded corners on all four sides, which facilitates the installation of the installation block 91.

[0033] In this embodiment, there are two adsorption modules 9, which are arranged at intervals along the length of the mounting rod 8; in this way, two suction cup assemblies 92 can be arranged on one mounting section 81, resulting in better adsorption capacity.

[0034] In this embodiment, the suction cup assembly 92 includes a vacuum generator 921, a suction cup 922, and a base 923. The vacuum generator 921 is fixed on the base 923. The negative pressure interface of the vacuum generator 921 passes through the base 923 and is connected to the suction cup 922. An external gas compression device is connected to the vacuum generator 921, so that the suction cup 922 can generate negative pressure. The mounting block 91 is provided with a through groove 913 that opens in a direction perpendicular to the mounting rod 8. The base 923 passes through the through groove 913. The base 923 and the mounting block 91 are detachably connected and the position can be adjusted along the opening direction of the through groove 913.

[0035] Guide blocks 914 are provided on the groove walls on both sides of the through groove 913 along its open direction. The base 923 is provided with a guide groove 924 extending in a direction perpendicular to the mounting rod 8. The guide groove 924 and the guide block 914 are slidably engaged. The mounting block 91 is provided with a second threaded hole 915. The second threaded hole 915 passes through the guide block 914 to connect the guide groove 924 with the outside. A screw is threaded into the second threaded hole 915.

[0036] When the screw is not tightened, the base 923 can move. By adjusting it to a suitable position using the guide groove 924 and the guide block 914, and then tightening the screw, the base 923 can be fixed in place, thereby determining the position of the suction cup 922.

[0037] In this embodiment, the auxiliary shaft 4 has an air chamber, and the auxiliary shaft 4 is provided with an air inlet 41 and an air outlet 42. The air inlet 41 and the air outlet 42 are respectively connected to the air chamber. The air inlet 41 is connected to an external gas compression device, while the air outlet 42 is connected to the vacuum generator 921 through an air pipe. This can reduce the length of the air pipe and prevent the air pipe from getting tangled on each swing arm.

[0038] Preferably, the second swing arm 6 separates the air inlet 41 and the air outlet 42, so that the air pipe will not be hit by the second swing arm 6, and the equipment is simpler and safer.

[0039] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
