Description

Technical Field

[0001] This invention relates to the field of cardboard packaging, specifically to the field of trapezoidal cardboard box gripping, and particularly to an adaptive adjustable vacuum suction cup device. Background Technology

[0002] Whether it's individual parcel delivery, small e-commerce businesses, or large enterprises, cardboard packaging is involved. For example... Figure 1 As shown, a trapezoidal cardboard box, as the name suggests, has a trapezoidal cross-section (usually an isosceles trapezoid) rather than a rectangle. This makes its two sides slanted, and it is mainly used for packaging products with a "small bottom and a large top" or those requiring good display. After packaging the product using trapezoidal cardboard boxes, the boxes containing the product need to be finally placed into larger cardboard boxes and stacked layer by layer. In existing technology, trapezoidal cardboard boxes are generally handled manually. However, trapezoidal cardboard boxes filled with products are quite heavy, and manual handling has the disadvantage of being labor-intensive. Moreover, workers are prone to accidentally dropping the trapezoidal cardboard boxes, which can easily damage the product.

[0003] To address the aforementioned issues, this invention proposes an adaptive adjustable vacuum suction cup device to assist in the manual handling of trapezoidal cardboard boxes, which is more labor-saving and more reliable. Summary of the Invention

[0004] To address the problems mentioned in the background above, the present invention provides an adaptive adjustable vacuum suction cup device.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0006] An adaptive adjustable vacuum suction cup device includes a main body fixing plate and an adsorption component; The upper surface of the main fixing plate is equipped with lifting rings, and the ceiling of the factory is equipped with lifting components. The lifting components and the lifting rings are connected by elastic ropes. Below the main fixing plate is a middle fixing plate. A cylinder is installed on the main fixing plate. The output end of the cylinder is fixed to the middle fixing plate. The cylinder is used to drive the middle fixing plate to move in the vertical direction. There are two cylinders, which are located at both ends of the main fixing plate. The adsorption component includes an upper adsorption assembly disposed on the lower surface of the central fixing plate and a side adsorption assembly disposed on the main fixing plate. The upper adsorption assembly is used to apply adsorption to the upper surface of the trapezoidal carton, and the side adsorption assembly is used to apply adsorption to the two sides of the trapezoidal carton that are arranged at an angle.

[0007] As a further improvement and optimization of the present invention, multiple adsorption components are arranged in an array along the extension direction of the main fixing plate.

[0008] As a further improvement and optimization of the present invention, the upper adsorption assembly includes an upper fixing plate connected to the middle fixing plate and an upper suction cup disposed on the lower surface of the upper fixing plate.

[0009] As a further improvement and optimization of the present invention, two upper fixing plates are provided and are respectively connected to the two sides of the middle fixing plate along the width direction, and two upper suction cups are provided accordingly.

[0010] As a further improvement and optimization of the present invention, the side adsorption assembly includes two side adsorption components, which are respectively located on both sides of the main body fixing plate along its own extension direction. The side suction component includes a main connecting plate connected to the main fixing plate, a side fixing plate is provided at the end of the main connecting plate away from the main fixing plate, and a side suction cup is provided at the end of the side fixing plate.

[0011] As a further improvement and optimization of the present invention, the main connecting plate includes an upper horizontal plate fixedly connected to the main fixing plate, a middle vertical plate arranged vertically at the end of the upper horizontal plate away from the main fixing plate, and a lower horizontal plate arranged at the lower end of the middle vertical plate away from the main fixing plate. The lower horizontal plate is provided with guide holes, and the guiding direction of the guide holes is parallel to the width direction of the main body fixing plate; The side fixing plate includes a side horizontal plate, the upper surface of which is attached to the lower surface of the lower horizontal plate. The side horizontal plate is provided with a through hole, which is connected to a guide hole. A connector is provided between the through hole and the guide hole. The connector is used to allow the side horizontal plate to have only the degree of freedom in the direction of the guide hole. The side horizontal plate is inclined downward at the end away from the main fixed plate. The distance between the two inclined plates of the same side adsorption component decreases from bottom to top in the vertical direction. Each of the two inclined plates of the same side adsorption component has a side suction cup vertically installed on the side where the ends of the two inclined plates face each other.

[0012] As a further improvement and optimization of the present invention, at least two guide holes are provided along the length direction of the main body fixing plate, and multiple through holes are provided accordingly.

[0013] As a further improvement and optimization of the present invention, the connecting member includes a bolt and a nut, the nut of the bolt contacts the upper surface of the lower horizontal plate, the end of the bolt passes through the guide hole and the through hole, and the nut is threaded on the bolt and the upper surface of the nut contacts the lower surface of the side horizontal plate.

[0014] As a further improvement and optimization of the present invention, an elastic connecting rope is provided between the two side horizontal plates of the same side adsorption component, and a sensor is provided on the side horizontal plate to monitor the change in length of the elastic connecting rope in real time.

[0015] As a further improvement and optimization of the present invention, the hoisting assembly includes a support body installed on the ceiling of the factory building, a rope winding drum installed on the support body and a coil spring provided at the installation point, an elastic rope wound on the rope winding drum, the end of the elastic rope being connected to a lifting ring, and a single handle provided on the main body fixing plate.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. When the upper suction cup contacts the upper surface of the trapezoidal cardboard box, the distance between the two side suction cups of the side suction assembly is less than the distance between the corresponding points on the two inclined surfaces of the trapezoidal cardboard box. Therefore, as the upper suction cup moves down to contact the upper surface of the trapezoidal cardboard box, the elastic connecting rope will be stretched, resulting in a centered clamping effect. This centering allows the upper and side suction cups to fit against the corresponding surfaces of the trapezoidal cardboard box, which is beneficial for the smooth implementation of subsequent negative pressure adsorption and allows the clamping to hold the trapezoidal cardboard box more stably. In addition, since the distance between the main fixing plate and the middle fixing plate is adjustable, and the upper suction cup is installed on the middle fixing plate while the side suction cup is installed on the main fixing plate, and since the side suction cup can adaptively move along the width direction of the main fixing plate, it can adapt to trapezoidal cartons of different sizes. On the other hand, the larger the size of the trapezoidal cartons, the greater the adaptive movement distance of the side suction cups, the greater the tensile displacement of the elastic connecting rope, and the greater the clamping force on the trapezoidal cartons. Since the larger the trapezoidal cartons, the greater their weight and the more difficult they are to clamp, this solution can adaptively change the clamping force on the trapezoidal cartons, resulting in a better clamping assistance effect. It should be noted that the clamping here refers to the clamping caused by the stretching of the elastic connecting rope, not negative pressure adsorption. 2. If the stretching distance of the elastic connecting rope changes during the movement of the trapezoidal cardboard box by this device, it indicates that the overall adsorption and clamping force on the trapezoidal cardboard box is too light and there is a risk that the trapezoidal cardboard box will fall. At this time, the sensor will immediately send a signal to make the operating power of the negative pressure pump reach the maximum to ensure that the trapezoidal cardboard box is released. In addition, during the trial operation of the equipment, the operating power of the negative pressure pump can be gradually reduced, and the stretching distance of the elastic connecting rope can be observed to determine the minimum operating power of the negative pressure pump corresponding to the trapezoidal cardboard box to be moved, thus achieving the effect of balancing energy saving and movement stability.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Reference Figures 1-8 An adaptive adjustable vacuum suction cup device includes a main body fixing plate 100.

[0021] A lifting ring 103 is provided on the upper surface of the main fixing plate 100. A lifting assembly is provided on the ceiling of the factory building. The lifting assembly and the lifting ring 103 are connected by an elastic rope. Furthermore, the lifting assembly includes a support body provided on the ceiling of the factory building. A rope winding drum is installed on the support body and a coil spring is provided at the installation point. The elastic rope is wound around the rope winding drum, and the end of the elastic rope is connected to the lifting ring 103. In addition, this device is made of lightweight materials, such as plastic or aluminum alloy, and is relatively light. Therefore, a single handle 104 is provided on the main fixing plate 100. The operator can easily pull the device between the location of the trapezoidal cardboard box and the location of the large cardboard box by holding the single handle 104, so as to put the trapezoidal cardboard box into the large cardboard box.

[0022] Below the main fixing plate 100, there is a middle fixing plate 101. A cylinder 102 is provided on the main fixing plate 100. The output end of the cylinder 102 is fixed to the middle fixing plate 101. The cylinder 102 is used to drive the middle fixing plate 101 to move in the vertical direction. Furthermore, there are two cylinders 102, which are located at both ends of the main fixing plate 100 respectively.

[0023] The device also includes adsorption components, which include an upper adsorption assembly 105 disposed on the lower surface of the central fixing plate 101 and a side adsorption assembly 106 disposed on the main fixing plate 100. Furthermore, multiple adsorption components are arranged in an array along the extending direction of the main fixing plate 100.

[0024] The upper adsorption component 105 is used to apply adsorption to the upper surface of the trapezoidal carton, and the side adsorption component 106 is used to apply adsorption to the two sides of the trapezoidal carton that are arranged at an angle.

[0025] Reference Figure 5 The upper adsorption assembly 105 includes an upper fixing plate 1051 connected to the middle fixing plate 101 and an upper suction cup 1052 disposed on the lower surface of the upper fixing plate 1051. Furthermore, there are two upper fixing plates 1051 and they are respectively connected to two sides of the middle fixing plate 101 along the width direction. There are two upper suction cups 1052 respectively.

[0026] Reference Figures 6-8 The side adsorption assembly 106 includes two side adsorption components, which are respectively located on both sides of the main body fixing plate 100 along its own extension direction.

[0027] The side adsorption component includes a main connecting plate 107 connected to the main fixing plate 100. Further, the main connecting plate 107 includes an upper horizontal plate 1071 fixedly connected to the main fixing plate 100. A vertically arranged middle vertical plate 1072 is provided at the end of the upper horizontal plate 1071 away from the main fixing plate 100, and a lower horizontal plate 1073 is provided at the lower end of the middle vertical plate 1072 in a direction away from the main fixing plate 100.

[0028] A side fixing plate 108 is provided at the end of the lower horizontal plate 1073. Furthermore, a guide hole 1074 is provided on the lower horizontal plate 1073. The guiding direction of the guide hole 1074 is parallel to the width direction of the main fixing plate 100. At least two guide holes 1074 are provided along the length direction of the main fixing plate 100.

[0029] The side fixing plate 108 includes a side horizontal plate 1081. The upper surface of the side horizontal plate 1081 is attached to the lower surface of the lower horizontal plate 1073. The side horizontal plate 1081 is provided with a through hole 1083, which communicates with the guide hole 1074. Multiple through holes 1083 are provided.

[0030] A connector 110 is provided between the through hole 1083 and the guide hole 1074. Further, the connector 110 includes a bolt 1101 and a nut 1102. The nut of the bolt 1101 contacts the upper surface of the lower horizontal plate 1073, and the end of the bolt 1101 passes through the guide hole 1074 and the through hole 1083. The nut 1102 is threaded on the bolt 1101, and the upper surface of the nut 1102 contacts the lower surface of the side horizontal plate 1081. Through the cooperation of the bolt 1101 and the nut 1102, the side horizontal plate 1081 only has the degree of freedom in the guiding direction of the guide hole 1074.

[0031] The side horizontal plate 1081 is inclined with a sloping plate 1082 at the end away from the main body fixing plate 100. The distance between the two sloping plates 1082 of the same side adsorption component 106 decreases from bottom to top in the vertical direction.

[0032] Each of the two inclined plates 1082 of the same side adsorption component 106 has a side suction cup 109 vertically arranged on the opposite side of its two inclined plates 1082.

[0033] An elastic connecting rope 111 is provided between the two side horizontal plates 1081 of the same side adsorption component 106. Furthermore, a sensor is provided on the side horizontal plate 1081 to monitor the length change of the elastic connecting rope 111 in real time, for example, by using distance sensor technology.

[0034] The working principle of this invention is specifically manifested as follows: The operator holds the single handle 104 and moves the device directly above the trapezoidal cardboard box. Then, the operator moves the device downward so that the upper suction cup 1052 contacts the upper surface of the trapezoidal cardboard box and the side suction cup 109 contacts the side of the trapezoidal cardboard box at an angle. Then, the negative pressure pump is activated to draw air from the upper suction cup 1052 and the side suction cup 109, thereby achieving negative pressure adsorption of the trapezoidal cardboard box through the upper suction cup 1052 and the side suction cup 109. Then, the staff continued to move the device to the top of the large cardboard box, and then moved the device downwards to put the trapezoidal cardboard box into the large cardboard box. Then the negative pressure pump stopped, the negative pressure adsorption disappeared, and the traction on the trapezoidal cardboard box was released. Then repeat the above process.

[0035] Its technological advantages lie in: 1. When the upper suction cup 1052 contacts the upper surface of the trapezoidal cardboard box, the distance between the two side suction cups 109 of the side adsorption component 106 is less than the distance between the corresponding points on the two inclined surfaces of the trapezoidal cardboard box. Therefore, during the process of the upper suction cup 1052 moving down to contact the upper surface of the trapezoidal cardboard box, the elastic connecting rope 111 will be stretched, which has a centering clamping effect. Centering allows the upper suction cup 1052 and the side suction cups 109 to fit with the corresponding surfaces of the trapezoidal cardboard box, which is conducive to the smooth implementation of subsequent negative pressure adsorption and the clamping can more stably clamp the trapezoidal cardboard box. In addition, since the distance between the main fixing plate 100 and the middle fixing plate 101 is adjustable, and the upper suction cup 1052 is installed on the middle fixing plate 101 and the side suction cup 109 is installed on the main fixing plate 100, and since the side suction cup 109 can adaptively move along the width direction of the main fixing plate 100, it can adapt to trapezoidal cartons of different sizes. On the other hand, the larger the size of the trapezoidal cartons, the greater the adaptive movement distance of the side suction cup 109, the greater the tensile displacement of the elastic connecting rope 111, and the greater the clamping force on the trapezoidal cartons. Since the larger the trapezoidal cartons, the greater their weight and the more difficult they are to clamp, this solution can adaptively change the clamping force on the trapezoidal cartons, resulting in a better clamping assistance effect. It should be noted that the clamping here refers to the clamping caused by the stretching of the elastic connecting rope 111, not negative pressure adsorption. 2. If the stretching distance of the elastic connecting rope 111 changes during the process of the device pulling the trapezoidal cardboard box, it indicates that the overall adsorption and clamping force on the trapezoidal cardboard box is too light and there is a risk that the trapezoidal cardboard box will fall. At this time, the sensor immediately sends a signal to make the negative pressure pump operate at maximum power to ensure that the trapezoidal cardboard box is released. In addition, during the trial operation of the equipment, the operating power of the negative pressure pump can be gradually reduced, and the change in the stretching distance of the elastic connecting rope 111 can be observed. This allows for the determination of the minimum operating power of the negative pressure pump corresponding to the trapezoidal cardboard box to be moved, achieving a balance between energy saving and stability during movement.
