Description

Technical Field

[0001] This utility model relates to the field of packaging feeding technology, specifically to a packaging paper picking and transferring device. Background Technology

[0002] In the production process of cigarette packaging, a piece of paper needs to be placed on each layer of cigarettes or cigarette trays to prevent the cigarettes from being damaged when stacked. In industrial production, robotic arms are usually used to pick up the stacked packaging paper one by one and transfer it to each layer of cigarettes. However, robotic arms are relatively expensive and have high maintenance costs. In order to reduce costs, some lower-cost picking and transferring devices have been developed and applied.

[0003] According to the utility model disclosure CN 215854085 U, the automatic paper feeding mechanism for an inkjet printer includes a frame, an automatic lifting and stacking paper platform, a vacuum paper suction component, a horizontal movement cylinder, a vertical movement cylinder, and a conveyor belt. The vacuum paper suction component is installed on the horizontal movement cylinder and is fixed to the top of the frame together with the vertical movement cylinder. The vacuum paper suction component, the horizontal movement cylinder, and the vertical movement cylinder are respectively connected to a gas compression device through air pipes. After the vacuum paper suction component descends linearly under the drive of the vertical movement cylinder and sucks in air, it automatically adsorbs the topmost packaging cardboard stacked on the automatic lifting and stacking paper platform. In addition, a photoelectric sensor is also provided in the device. However, during use, as the packaging cardboard is continuously transferred, the height of the paper stack decreases continuously. The vacuum paper suction component cannot adjust its descent stroke according to the height of the paper stack, thus preventing the vacuum paper suction component from contacting the cardboard on top of the paper stack. The photoelectric sensor in the device is used to control the automatic lifting and positioning of the paper stacking platform, but this control process is not based on the height of the paper stack. Therefore, the device cannot control the gripping stroke according to the height of the paper stack. Utility Model Content

[0004] The purpose of this invention is to provide a packaging paper picking and transferring device that can control the gripping stroke according to the height of the paper stack, so as to facilitate the contact and adsorption between the suction nozzle and the top paper, thereby overcoming the problems described in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A packaging paper picking and transferring device, comprising:

[0007] A linear motion mechanism is mounted on a fixed plate and has a movable plate that allows the movable plate to move in a linear direction.

[0008] The movable plate includes a horizontal plate and a vertical plate, which are vertically connected. The horizontal plate is connected to a linear movement mechanism, and the vertical plate extends vertically to the bottom of the fixed plate. A sliding component is slidably mounted on the vertical plate, and a drive mechanism for driving the sliding component to slide up and down is also mounted on the vertical plate. An L-plate is connected to the sliding component.

[0009] The nozzle support is made of square steel pipes connected horizontally and vertically. The nozzle support is set on the bottom surface of the L-plate and a nozzle connecting plate is set on the horizontal or vertical arm of the nozzle support. The nozzle connecting plate is equipped with a nozzle.

[0010] The first detection component includes a pressure rod, a mounting bracket, and a first proximity switch. The pressure rod is vertically inserted into the L-plate, allowing it to move up and down. The mounting bracket is fixedly mounted on the L-plate, and the first proximity switch is mounted on the mounting bracket. The pressure rod is located directly below the first proximity switch.

[0011] Furthermore, the linear movement mechanism is a linear module, the horizontal plate is connected to the slider of the linear module, a guide slider is also provided on the bottom surface of the horizontal plate, and a guide rail is provided on the fixed plate. The guide rail is parallel to the linear module and the guide slider is slidably mounted on the guide rail.

[0012] Furthermore, vertical guide rails are provided on both sides of the vertical plate, and the sliding component includes a vertical slider, a sliding plate, and a moving block. The vertical slider is connected to both sides of the sliding plate and is slidably disposed on the vertical guide rails. The moving block is connected to the middle of the sliding plate and is connected to the driving mechanism.

[0013] Furthermore, the drive mechanism includes a servo motor, a reciprocating lead screw, and a lead screw end seat. The lead screw end seat is mounted on the vertical plate, and the reciprocating lead screw is rotatably connected to the lead screw end seat. The output end of the servo motor is connected to one end of the reciprocating lead screw. The moving block is a lead screw sleeve rotatably mounted on the bottom surface of the sliding plate, and the reciprocating lead screw is threadedly connected to the lead screw sleeve.

[0014] Furthermore, the fixed plate is slidably provided with an edge slider, and a detection part is provided on the edge slider. A second proximity switch is provided on the back of the vertical plate, and the detection part and the second proximity switch are located in the same horizontal plane.

[0015] Furthermore, when the suction nozzle contacts the packaging paper, the top of the pressure rod contacts the first proximity switch.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a first detection component on an L-plate, comprising a pressure rod, a mounting bracket, and a first proximity switch. During the descent of the L-plate, the pressure rod contacts the top layer of the paper stack, causing it to rise and engage with the first proximity switch, triggering a signal. At this point, the L-plate stops moving, and the suction nozzle generates negative pressure to adsorb the top layer of cardboard. This allows the descent stroke of the L-plate to be controlled according to the height of the paper stack, ensuring the suction nozzle can smoothly pick up the cardboard. Furthermore, this invention includes a detection unit that slides along the edge of the fixed plate and a second proximity switch on the back of the vertical plate. The release position of the cardboard is controlled by moving the detection unit, making the operation simple and convenient. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Please see Figure 1-4 This utility model provides a packaging paper picking and transferring device, comprising:

[0027] A linear motion mechanism 2 is mounted on a fixed plate 1 and a movable plate 4 is mounted on the linear motion mechanism so that the movable plate 4 can move along a linear direction.

[0028] In some embodiments, the linear movement mechanism 2 is a linear module.

[0029] The movable plate 4 includes a horizontal plate 41 and a vertical plate 42, which are vertically connected. The horizontal plate 41 is connected to a linear movement mechanism, specifically, the horizontal plate 41 is connected to the slider of the linear module. The vertical plate 42 extends vertically below the fixed plate 1. A sliding component 8 is slidably disposed on the vertical plate 42, and a driving mechanism for driving the sliding component 8 to slide up and down is also disposed on the vertical plate 42. An L-plate 7 is connected to the sliding component 8.

[0030] A guide slider 15 is also provided on the bottom surface of the horizontal plate 41, and a guide rail 3 is provided on the fixed plate 1. The guide rail 3 is parallel to the linear module and the guide slider 15 is slidably disposed on the guide rail 3. In this way, the stability of the horizontal plate 41 during movement is ensured.

[0031] The nozzle support 10 is made of square steel pipes connected horizontally and vertically. Preferably, there are two horizontally arranged directional steel pipes and two vertically arranged directional steel pipes. The nozzle support 10 is set on the bottom surface of the L plate 7 and a nozzle connecting plate 11 is set on the horizontal or vertical arm of the nozzle support 10. A nozzle 12 is set on the nozzle connecting plate 11.

[0032] Specifically, multiple suction nozzles 12 are connected to air distribution nozzles via air tubes, and the air distribution nozzles are connected to a negative pressure pump via air tubes. This allows the negative pressure pump to draw air from each suction nozzle 12 through the air distribution nozzles, thereby generating negative pressure at the suction nozzles 12.

[0033] In some embodiments, the nozzle connecting plate 11 can be slidably connected to the horizontal or vertical arm of the nozzle support 10, thereby allowing the position of the nozzle 12 to be changed according to the size of the paper.

[0034] The first detection component 9 includes a pressure rod 91, a mounting bracket 92, and a first proximity switch 93. The pressure rod 91 is made of lightweight material and is vertically mounted on the L-plate 7, allowing it to move up and down. The mounting bracket 92 is fixedly mounted on the L-plate 7, and the first proximity switch 93 is mounted on the mounting bracket 92. The pressure rod 91 is located directly below the first proximity switch 93. Furthermore, when the suction nozzle 12 contacts the packaging paper, the top of the pressure rod 91 contacts the first proximity switch 93. This means that in its natural state, the bottom of the pressure rod 91 must be lower than the bottom surface of the suction nozzle 12.

[0035] In actual use, as the packaging paper is continuously transferred, the overall thickness of the packaging paper stack decreases. The first detection component 9 provides feedback on the descent of the L-plate 7, ensuring that the suction nozzle 12 can stop the movement of the L-plate 7 in time when it contacts the top layer of cardboard. Specifically, as the L-plate 7 moves downward, when the bottom end of the top pressure rod 91 contacts the top layer of cardboard, the top pressure rod 91 is pushed upward, causing its top end to approach or press the first proximity switch 93. The first proximity switch 93 then stops the drive mechanism and activates the negative pressure pump.

[0036] The vertical plate 42 is provided with vertical guide rails 6 on both sides. The sliding component 8 includes a vertical slider 82, a sliding plate 83 and a moving block 81. The vertical slider 82 is connected to both sides of the sliding plate 83 and is slidably disposed on the vertical guide rails 6, thereby ensuring the smooth movement of the sliding plate 83. The sliding plate 83 is connected to the L plate 7. The moving block 81 is connected to the middle of the sliding plate 83 and is connected to the driving mechanism.

[0037] In some embodiments, the driving mechanism includes a servo motor 5, a reciprocating lead screw 17, and a lead screw end seat 18. The lead screw end seat 18 is mounted on the vertical plate 42, and the reciprocating lead screw 17 is rotatably connected to the lead screw end seat 18. The output end of the servo motor 5 is connected to one end of the reciprocating lead screw 17. The moving block 81 is a lead screw sleeve rotatably mounted on the bottom surface of the sliding plate 83. The reciprocating lead screw 17 is threadedly connected to the lead screw sleeve. In this embodiment, the servo motor 5 drives the reciprocating lead screw 17 to rotate, thereby driving the sliding plate 83 to move up and down. Of course, the driving mechanism can also adopt a cylinder or other structure, and this utility model does not limit this.

[0038] The fixed plate 1 is slidably provided with an edge sliding member 13, and a detection part 14 is provided on the edge sliding member 13. A second proximity switch 16 is provided on the back of the vertical plate 42. The detection part 14 and the second proximity switch 16 are located in the same horizontal plane.

[0039] In actual use, the unloading position of the packaging paper needs to be adjusted according to the actual situation. When adjusting, simply move the edge slider 13. When the movable plate 4 moves along the edge of the fixed plate 1, the second proximity switch 16 approaches the detection part 14, causing the second proximity switch 16 to be triggered, thereby controlling the linear movement mechanism 2 to stop working.

[0040] The device also includes a controller, which is electrically connected to a first proximity switch 93, a second proximity switch 16, a servo motor 5, a linear module, and a negative pressure pump. The controller is used to perform the following actions: controlling the movement of the servo motor 5 and the linear module; stopping the servo motor 5 and turning on the negative pressure pump when the top pressure rod 91 triggers the first proximity switch 93; and stopping the linear module and turning on the servo motor 5 when the second proximity switch 16 is triggered. The specific structure of the controller can be configured by those skilled in the art based on the execution process of the controller.

[0041] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
