Description

Technical Field

[0001] The utility model relates to the field of lifting devices, in particular to a lifting device for a bag arranging and stacking machine. Background Art

[0002] Packaging bags are a form of packaging widely used in daily life and industrial production. They are designed to protect products, facilitate transportation and storage, and at the same time undertake certain marketing functions. In the packaging industry, bag arranging is a part of the production process, that is, the process of arranging the bags used for packaging by workers or machines. A bag arranging machine is an automated packaging machine widely used in multiple industries such as food, medicine, and chemical industry, and is used for automatically bagging, opening bags, and sealing bags of various different-shaped items.

[0003] The bag arranging machine includes a base. A frame is fixedly installed at the top of the base. An electric box is provided on the left side of the frame. A moving seat is fixedly installed at the front end of the top of the frame. A robot body is fixedly installed on the top of the moving seat. A robot power distribution cabinet is fixedly installed on the right side inside the frame. A lifting mechanism is provided at the bottom inside the frame. A bag receiving mechanism is installed at the top inside the frame. A bag patting mechanism is provided at the front end of the top inside the frame. Bags receive the finished bag-making products at the entrance of the conveyor belt. After passing through the detection by the conveyor belt mechanism, the defective products are sent into the waste conveyor belt through the waste discharging device of the conveyor belt mechanism and discharged, while the qualified products are sent into the bag receiving mechanism for sorting and storage. When the storage reaches the set quantity, the push rod at the rear side of the receiving bin is pushed up, and after being sorted in cooperation with the bag patting mechanism, the receiving bin is layered and slowly lowered to the set position by the lifting combination of the lifting mechanism, and is grabbed by the preset manipulator body to the bundling machine to complete bundling, and then the boxing action is carried out.

[0004] In the existing lifting mechanism for bag arranging, a number of material receiving components are provided. After the material receiving components rise, they catch the packaging bags falling from the conveyor belt, and slowly descend during the material receiving process, and the descending speed is the same as the material falling speed to ensure that the falling height of each packaging bag is the same. At the same time, a baffle is provided between the conveyor belt and the lifting mechanism. The baffle encloses a material falling channel, and the material falling channel is close to the size of the packaging bag to prevent the packaging bag from falling after landing on the material receiving component. If the position of the baffle is not adjusted properly, the material receiving component is likely to collide with the baffle when rising, resulting in deformation of the baffle. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art solutions, the utility model provides a lifting device for a bag arranging and stacking machine, which can effectively solve the technical problem that the material receiving component is likely to collide with the baffle when rising, resulting in deformation of the baffle.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Lifting device for a bag sorting and stacking machine, comprising a fixed frame, a movable plate and a driving component. The fixed frame can be installed on the bag sorting machine. The movable plate is slidably arranged inside the fixed frame. The driving component is installed on the fixed frame and can drive the movable plate to move up and down. A plurality of material receiving components are arranged on the fixed frame. Each material receiving component consists of a material receiving rod and a lifting rod. The material receiving rod is located outside the fixed frame. The lifting rod is arranged at one end of the material receiving rod close to the fixed frame. The end of the lifting rod away from the material receiving rod passes through the surface of the fixed frame and is provided with a positioning ring groove. A plurality of positioning holes are arranged on the movable plate. The material receiving rod is inserted into the positioning holes. Elastic clamping parts are arranged on the side walls of the positioning holes. The elastic clamping parts can engage with the positioning ring groove. When the elastic clamping parts engage with the positioning ring groove, the movable plate and the material receiving rod move synchronously. Each material receiving component can be separately removed from the movable plate and the fixed frame.

[0008] Further, the fixed frame includes a bottom plate, a top fixing plate and support columns. The two ends of the support columns are respectively fixedly connected to the bottom plate and the top fixing plate. A lifting area is formed between the bottom plate and the top fixing plate. The movable plate is arranged in the lifting area and is slidably connected with the support columns. The two ends of the ball screw are respectively rotatably connected to the top fixing plate and the bottom plate, and the other end is in transmission connection with the driving motor. The material receiving rod is located at one end of the top fixing plate away from the bottom plate. The lifting rod passes through the top fixing plate and is clamped with the movable plate.

[0009] Further, linear bearings are arranged on the surfaces of the movable plate and the top fixing plate. The movable plate is slidably connected with the support columns through the linear bearings. The top fixing plate is slidably connected with the lifting rod through the linear bearings.

[0010] Further, the driving component includes a ball screw, a screw nut and a driving motor. The ball screw is rotatably connected to the top fixing plate. The driving motor is installed on the fixed frame and is in transmission connection with the ball screw. The movable plate is connected to the ball screw through the screw nut. When the ball screw rotates, the movable plate can move axially inside the fixed frame along the ball screw.

[0011] Further, the driving motor is installed at one end of the bottom plate away from the top fixing plate. One end of the ball screw close to the bottom plate extends out of the bottom plate and is in transmission connection with the driving motor through a coupling.

[0012] Further, the elastic clamping part consists of a spring and a steel ball. An installation hole is arranged on the side wall of the positioning hole. The spring is arranged in the installation hole. The steel ball is arranged at one end of the spring close to the positioning hole. Under the action of the spring, the steel ball can engage with the positioning ring groove.

[0013] Further, the installation hole is a through hole. One end of the installation hole away from the positioning hole extends to the side wall of the movable plate and is threadedly connected with an adjusting nut. One end of the spring away from the steel ball abuts against the adjusting nut.

[0014] Furthermore, an induction switch is provided on the fixing frame, and the induction switch is used to detect the extreme position where the movable plate can move.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: A number of material receiving components are provided. The material receiving component is composed of a material receiving rod and more than two lifting rods. The lifting rods pass through the surface of the fixing frame and are provided with positioning ring grooves. The movable plate is provided with positioning holes. The material receiving rod is inserted into the positioning holes. Elastic clamping members are provided on the side walls of the positioning holes. The elastic clamping members can engage with the positioning ring grooves. The material receiving component is not fixedly connected to the movable plate. When the driving component drives the movable plate to rise, the movable plate and the material receiving rod move synchronously. Since the lifting rod is connected to the movable plate by the elastic clamping member engaging with the positioning ring groove, when there is interference between a material receiving rod and the side baffle on the bag arranging machine, the movable plate continues to rise, and the surface of the lifting rod presses the elastic clamping member, causing the elastic clamping member to disengage from the positioning ring groove, and the movable plate cannot continue to drive this material receiving component to rise. When the movable plate descends to the lowest end, the elastic clamping member engages with the positioning ring groove again, avoiding the side baffle on the bag arranging machine being deformed by the material receiving component, and the material receiving component that interferes with the side baffle can be pulled out after one lifting is completed, avoiding continued collision with the side baffle during subsequent liftings.

Detailed Embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Next, in conjunction with Figures 1 - 5 a detailed description of the lifting device for the bag arranging and stacking machine of the present utility model will be given:

[0024] The lifting device for the bag arranging and stacking machine includes a fixed frame, a movable plate 1, a driving motor 2, a ball screw 3 and a screw nut 4. The fixed frame can be installed on the bag arranging machine. The movable plate 1 is slidably arranged in the fixed frame. The ball screw 3 is rotatably connected to the inner wall of the fixed frame. The driving motor 2 is installed on the fixed frame and is in transmission connection with the ball screw 3. The movable plate 1 is connected to the ball screw 3 through the screw nut 4. When the ball screw 3 rotates, the movable plate 1 can move axially along the ball screw 3 in the fixed frame. An inductive switch 12 is arranged on the fixed frame. The inductive switch 12 is used to detect the limit position where the movable plate 1 can move. When the movable plate 1 moves to the highest point or the lowest point, the inductive switch 12 cuts off the power supply of the driving motor 2 to prevent the movable plate 1 from continuing to move.

[0025] A number of material receiving components 9 are arranged on the fixing frame. The material receiving component 9 is composed of a material receiving rod 901 and two lifting rods 902. The material receiving rod 901 is located outside the fixing frame. The lifting rod 902 is arranged at one end of the material receiving rod 901 close to the fixing frame. The lifting rod 902 passes through the surface of the fixing frame and is provided with a positioning ring groove 903. A number of positioning holes are arranged on the movable plate 1. The material receiving rod 901 is inserted into the positioning holes. Elastic clamping members 10 are arranged on the side walls of the positioning holes. The elastic clamping members 10 can engage with the positioning ring groove 903. When the elastic clamping members 10 engage with the positioning ring groove 903, the movable plate 1 and the material receiving rod 901 move synchronously. Each material receiving component 9 can be separately removed from the movable plate 1 and the fixing frame. The elastic clamping member 10 is composed of a spring 1001 and a steel ball 1002. Mounting holes 11 are arranged on the side walls of the positioning holes. The steel ball 1002 and the spring 1001 are arranged in the mounting holes 11. The steel ball 1002 is arranged at one end of the spring 1001 close to the positioning hole. The steel ball 1002 can move along the inner wall of the mounting hole 11 in the mounting hole 11. Under the action of the spring 1001, the steel ball 1002 can engage with the positioning ring groove 903. The mounting hole 11 is a through hole. One end of the mounting hole 11 far from the positioning hole extends to the side wall of the movable plate 1 and is threadedly connected with an adjusting nut 1003. One end of the spring 1001 far from the steel ball 1002 abuts against the adjusting nut 1003. Rotating the adjusting nut 1003 can change the extrusion degree of the spring 1001, thereby changing the engaging force between the steel ball 1002 and the positioning ring groove 903.

[0026] The fixing frame includes a bottom plate 5, a top fixing plate 6 and support columns 7. Two ends of the support columns 7 are respectively fixedly connected to the corners of the bottom plate 5 and the top fixing plate 6. A lifting area is formed between the bottom plate 5 and the top fixing plate 6. The movable plate 1 is arranged in the lifting area. The movable plate 1 is slidably connected with the support columns 7. Two ends of the ball screw 3 are respectively rotatably connected to the top fixing plate 6 and the bottom plate 5, and the other end is in transmission connection with the driving motor 2. The material receiving rod 901 is located at one end of the top fixing plate 6 far from the bottom plate 5. The lifting rod 902 passes through the top fixing plate 6 and is clamped with the movable plate 1. Linear bearings 8 are arranged on the surfaces of the movable plate 1 and the top fixing plate 6. The movable plate 1 is slidably connected with the support columns 7 through the linear bearings 8. The top fixing plate 6 is slidably connected with the lifting rod 902 through the linear bearings 8, so that the movable plate 1 and the lifting rod 902 are more stable and smooth during the lifting process, preventing the lifting rod 902 or the movable plate 1 from tilting and causing jamming with the top fixing plate 6 or the support columns 7. The driving motor 2 is installed at one end of the bottom plate 5 far from the top fixing plate 6. One end of the ball screw 3 close to the bottom plate 5 extends out of the bottom plate 5 and is in transmission connection with the driving motor 2 through a coupling.

[0027] The lifting device for the bag arranging and stacking machine in this embodiment is provided with a number of material receiving components 9. The material receiving component 9 is composed of a material receiving rod 901 and two lifting rods 902. The lifting rods 902 pass through the surface of the fixed frame and are provided with positioning ring grooves 903. The movable plate 1 is provided with positioning holes. The material receiving rod 901 is inserted into the positioning holes. The side wall of the positioning hole is provided with elastic clamping members 10. The elastic clamping members 10 can engage with the positioning ring grooves 903. When the ball screw 3 drives the movable plate 1 to rise, the movable plate 1 moves synchronously with the material receiving rod 901. Since the lifting rod 902 is connected to the movable plate 1 by engaging the positioning ring groove 903 through the elastic clamping member 10, when there is interference between the position of the material receiving rod 901 and the side baffle 13 on the bag arranging machine, as Figure 5 described, when the movable plate 1 continues to rise, the material receiving rod 901 is blocked by the side baffle 13, and the lifting rod 902 moves downward relative to the movable plate 1, squeezing the steel balls 1002 of the positioning ring groove 903, so that the steel balls 1002 disengage from the positioning ring groove 903. When the positioning ring groove 903 is not engaged with the steel balls 1002, the movable plate 1 cannot continue to drive this material receiving component 9 to rise. When the movable plate 1 descends to the lowest end, the positioning hole is aligned with the positioning ring groove 903, and the steel balls 1002 are re-engaged with the positioning ring groove 903 under the action of the spring 1001, avoiding the side baffle 13 on the bag arranging machine being deformed by the material receiving component 9, and after a lifting is completed, the material receiving component 9 interfering with the side baffle 13 can be separately withdrawn to avoid continued collision with the side baffle 13 during subsequent liftings.
