Description

Technical Field

[0001] The invention relates to the technical field of welding wire production, and in particular to an automatic feeding device for welding wire packaging. Background Art

[0002] During the production process of welding wire, the welding wire needs to be wound on the wire reel first, and then the wire reel is packaged with a thin film to prevent oxidation. After the wire reel is made and transferred to the packaging line, a conveyor belt is generally required for conduction. Under normal circumstances, the production rhythm of the packaging line is faster than the production rhythm of the wire reel production line to avoid the accumulation and blockage of the wire reel on the conveyor belt. When the packaging line and the wire reel production line are operating normally, the rhythm of the entire production line is smooth. However, when the packaging line fails and stops, the wire reel production line is still in production, and workers are required to move the wire reel on the conveyor belt down for temporary storage, and then move the wire reel back to the conveyor belt after the packaging line is restored. This back and forth is not only labor-intensive, but also inefficient.

[0003] In view of this, an automatic feeding device for welding wire packaging is designed, which can automatically transfer the wire reel on the conveyor belt when the above-mentioned packaging line stops, and automatically feed the packaging line after the packaging line resumes, thereby avoiding waste of manpower and improving feeding efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic feeding device for welding wire packaging to solve the problems described in the background technology.

[0005] The technical solution of the present invention is achieved in this way:

[0006] The lifting mechanism is arranged beside the roller conveyor, the lifting mechanism comprises an inlet and an outlet, the outlet of the lower rotary slide is connected to the inlet of the lifting mechanism, the lifting mechanism is used to receive the material discharged by the lower rotary slide and lift the material to a preset position and the material height is not lower than the transport receiving surface of the roller conveyor belt, the first telescopic mechanism is also connected to the first telescopic mechanism, the feed pull plate is arranged above the roller conveyor belt, the first telescopic mechanism is used to control The feed pull plate is controlled to move so as to pull the material on the transport receiving surface into the entrance of the lower rotary slide. The second telescopic mechanism is also connected to a material blocking rod, and the second telescopic mechanism is used to control the movement of the material blocking rod to block the exit of the lower rotary slide and the entrance of the lifting mechanism to prevent the material from entering the lifting mechanism from the lower rotary slide. The third telescopic mechanism is also connected to a discharge push plate, and the third telescopic mechanism is used to control the movement of the discharge push plate so as to push the material lifted to a predetermined position by the lifting mechanism out of the exit of the lifting mechanism and into the transport receiving surface. A first sensor, a second sensor and a controller are also provided above the bottom plate. The first sensor is used to detect the material on the transport receiving surface at the entrance of the lower rotary slide, and the second sensor is used to detect the material when the lifting mechanism is lifted to a preset position. The first sensor, the second sensor, the first telescopic mechanism, the second telescopic mechanism and the third telescopic mechanism are all electrically connected to the controller.

[0007] When the above scheme is used, the material (reel) flows out of the reel production line and enters the roller conveyor belt. The inclined transport receiving surface allows the material to automatically slide to the packaging line under the action of gravity. When the packaging line is shut down, the material storage and output mechanism is started, and the first telescopic mechanism controls the feed pull plate to extend so that the feed pull plate is located on the transport receiving surface. The first sensor detects the material on the transport receiving surface. When the material passes through the first sensor, the first sensor sends a detection signal to the controller. The controller controls the first telescopic mechanism after receiving the detection signal for a preset period of time. The first telescopic mechanism controls the feed pull plate to retract and pull the material on the transport receiving surface from the entrance of the lower spin slide into the lower spin slide, and slides along the lower spin slide to the bottom of the lower spin slide. At this time, the second telescopic mechanism controls the material blocking rod to extend to prevent the material from entering the lifting mechanism. The materials are accumulated and stored in the lower spin slide one by one until the lower spin slide is full.

[0008] Multiple material storage and output mechanisms can be set up along the roller conveyor belt, or the length of the downward rotation slide can be increased to increase the material storage capacity.

[0009] By arranging a downward rotating slideway in cooperation with the first telescopic mechanism, the wire reels on the conveyor belt can be automatically transferred when the packaging line is stopped, thereby realizing automatic storage.

[0010] When the packaging line is restored and the wire drum production line has completed its production task and stopped, the lifting mechanism can be started to automatically feed the packaging line. At this time, the second telescopic mechanism controls the material blocking rod to retract, and the material slides from the entrance of the lifting mechanism into the lifting mechanism under the action of gravity. The second telescopic mechanism then controls the material blocking rod to extend to block the next material, thereby realizing single feeding to the lifting mechanism. The lifting mechanism is lifted to a preset position. After the second sensor senses the material, it sends a detection signal to the controller. After receiving the detection signal for a preset period of time, the controller controls the third telescopic mechanism to extend, and the discharge push plate extends to push the material out of the outlet of the lifting mechanism, so that it enters the transport receiving surface. Then the lifting mechanism returns to its original position and receives the next material, and repeats this process until all the materials in the lower rotary slide are discharged. The lifting time of the lifting mechanism and the telescopic time of the second telescopic mechanism can be set and operated according to the beat time.

[0011] A further technical solution is that the downward rotation slide includes a frame, and also includes multiple inclined straight slides, multiple inclined curved slides and a discharging slide. The inclined straight slide and the discharging slide are inclined slides, and the inclined curved slide is a downwardly inclined slide. Multiple inclined straight slides are fixed on the frame at intervals from top to bottom, and multiple inclined curved slides are fixed on the frame at intervals from top to bottom. One end of the topmost inclined straight slide among the multiple inclined straight slides is connected to the inclined curved slide and the other end is the entrance of the downward rotation slide. Both ends of the remaining inclined straight slides among the multiple inclined straight slides are connected to the inclined curved slide. One end of the bottommost inclined curved slide among the multiple inclined curved slides is connected to the inclined straight slide and the other end is connected to the discharging slide. The other end of the discharging slide is the outlet of the downward rotation channel, and the discharging slide is fixed on the frame.

[0012] A further technical solution is that the material lifting mechanism includes four vertical slide rails fixed on the bottom plate, and the four vertical slide rails are distributed according to the four corners of the virtual rectangle. The material lifting mechanism also includes a material receiving slide, which is an inclined straight slide, and the inclination direction of the material receiving slide is consistent with the inclination direction of the material discharging slide. The outer wall of the material receiving slide is slidably connected to the four vertical slide rails, and one end of the material receiving slide is connected to the outlet of the downward rotation slide, and the end of the material receiving slide connected to the outlet of the downward rotation slide is the entrance of the material lifting mechanism. A vertical plate is also fixed on the end of the material receiving slide opposite to the entrance of the material lifting mechanism, and a motor is also fixed on the outside of the vertical plate. A gear is also provided on the output shaft of the motor, and a rack meshed with the gear is provided on the outer wall of the vertical slide rail, and the rack extends from bottom to top along the vertical slide rail. The motor is electrically connected to the controller, and the end of the material receiving slide facing the roller conveyor belt is the outlet of the material lifting mechanism.

[0013] When using the above scheme, after the second telescopic mechanism controls the material stopping rod to retract, the material enters the material receiving chute from the discharging chute under the action of gravity, and the vertical plate is used to stop the material. After the second telescopic mechanism controls the material stopping rod to extend, the motor starts, and the motor controls the gear to rotate. The gear meshes and rotates on the rack, thereby driving the material receiving chute to rise. When the material receiving chute is lifted to the preset position, the second sensor detects the material on the material receiving chute, and the third telescopic mechanism controls the discharge push plate to push the material on the material receiving chute out of the outlet of the lifting mechanism. Then the motor reverses and drives the material receiving chute to move down again and return to the initial position.

[0014] A further technical solution is that the feed pull plate includes a connecting rod, a connecting plate, a baffle and a pull plate, one end of the connecting rod is connected to the first telescopic mechanism, the other end of the connecting rod is fixedly connected to the connecting plate, one end of the baffle is fixedly connected to the connecting plate, the other end of the baffle is fixedly connected to the pull plate, the baffle and the pull plate are perpendicular to each other, and the baffle and the transport direction of the roller conveyor belt are perpendicular to each other.

[0015] When using the above solution, the first telescopic mechanism controls the extension and retraction of the connecting rod, the connecting rod drives the connecting plate, the connecting plate drives the baffle, and the baffle drives the pull plate. When the material flows to the entrance of the lower rotary chute, it is blocked by the baffle and then pulled into the lower rotary chute by the pull plate.

[0016] A further technical solution is that the first telescopic mechanism includes a first bracket fixed on the base plate, a first telescopic cylinder is fixed on the first bracket, the first telescopic cylinder is electrically connected to the controller, the telescopic rod of the first telescopic cylinder is fixedly connected to the connecting rod, a sleeve is also fixed on the first bracket, a sliding rod is slidably inserted in the sleeve, the sliding rod is parallel to the telescopic rod of the first telescopic cylinder, and the other end of the sliding rod is fixedly connected to the connecting plate.

[0017] A further technical solution is that the second telescopic mechanism includes a second bracket fixed on the base plate, a second telescopic cylinder is fixed on the second bracket, the second telescopic cylinder is electrically connected to the controller, and a telescopic rod of the second telescopic cylinder is fixedly connected to the material blocking rod.

[0018] A further technical solution is that the third telescopic mechanism includes a third bracket fixed on the base plate, a third telescopic cylinder is fixed on the third bracket, the third telescopic cylinder is electrically connected to the controller, and a telescopic rod of the third telescopic cylinder is fixedly connected to the discharge push plate.

[0019] A further technical solution is that a plurality of cushion blocks made of elastic material are also provided at the bottom of the material receiving slideway.

[0020] When the above solution is used, when the material receiving slide is reset to the bottom, the cushion block can contact the bottom plate, thereby limiting the position of the material receiving slide and also playing a shock absorbing role.

[0021] A further technical solution is that an inclined plate is provided between two of the four vertical slide rails facing the roller conveyor belt, the end of the inclined plate facing the roller conveyor belt is lower than the end away from the roller conveyor belt, the lower end of the inclined plate is not lower than the transport receiving surface, and the higher end of the inclined plate is not higher than the upper end surface of the material receiving slide lifted to the preset position.

[0022] A further technical solution is that the motor is a servo motor.

[0023] The beneficial effects of the present invention are:

[0024] 1. High degree of automation: Through the coordinated work of multiple telescopic mechanisms, sensors, controllers and other components, the automatic storage of materials when the packaging line is shut down and the automatic feeding after recovery are realized, which reduces manpower consumption and improves production efficiency.

[0025] 2. Large storage capacity and flexible adjustment: The material storage capacity can be increased by setting up multiple material storage and output mechanisms or increasing the length of the downward rotation slide, which meets the needs of different production scales and is easy to adjust.

[0026] 3. Precise control: The sensor detects the material position, and the controller accurately controls the movement of the telescopic mechanism according to the received signal, ensuring the accuracy and stability of the material during storage and feeding.

[0027] 4. Adjustable tact time: The lifting time of the lifting mechanism and the telescopic time of the second telescopic mechanism can be set according to the production tact time, making the whole solution more adaptable to the actual needs of the production line.
