Description

Technical Field

[0001] This utility model relates to the field of tinplate technology, specifically a feeding mechanism for can making. Background Technology

[0002] In the tinplate can manufacturing industry, most manufacturers use automated welding can manufacturing processes. This production line is fast and efficient. After the raw iron plates are cut, they are sorted by a sorting mechanism and formed into neat stacks on a double belt conveyor. Then, they are lifted and transferred by a robotic arm and enter the hopper of the automated welding machine.

[0003] In the prior art, patent application number 201710846021.9 discloses an automatic sorting and feeding robot for food packaging can production. This patent discloses a technology that stacks cut iron plates using a device, and then uses a robot to transfer the stacked iron plates one stack at a time. In this prior art, a lifting and lowering sheet material collection and transfer device is used to lift the iron plate stacks from the conveying device, and then the robot, which can extend, lift, and move horizontally, grabs and transfers them. In this process, each time an iron plate stack is lifted and transferred, the robot and sheet material collection and transfer device have to perform a reciprocating motion. This consumes electrical energy, and the frequent movements will lead to accelerated wear of the transmission components in various parts, affecting the service life of the equipment.

[0004] Therefore, the problem that the inventors wanted to solve was to design a device that could lift multiple stacks at once, improve lifting efficiency, reduce the number of lifting actions, and thus extend service life. Utility Model Content

The sliding sleeve and the insert block are slidably engaged, and one end of the sliding sleeve is flush with the inner side wall of the upright frame.

[0009] Furthermore, the lower end of the insert near the inner side of the upright is provided with a chamfered structure.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0021] Example 1: See Figures 1 to 3 These are the bottom structural view, structural view, and rear view of this utility model. This utility model is an innovation and improvement based on the existing technology of an automatic sorting and feeding robot for food packaging can production. It is perfectly combined with other mechanisms of the original equipment. A feeding mechanism for can making is provided, which is set on the slider of the vertical lifting mechanism. The feeding mechanism is located on the outside of the end of the double belt conveyor 11 and does not contact the double belt conveyor 11. Multiple stacked iron plates 13 are set on the double belt conveyor 11. The length of 3 is less than the distance between the two side walls of the upright 2. The feeding mechanism includes a base frame 1, the upper end of which is connected to the upright 2. A reinforcing rib 3 is connected between the side walls of the base frame 1 and the upright 2. The reinforcing rib 3 on both sides can effectively strengthen the overall structure. An opening slot 4 is provided on one end face of the upright 2. The opening slot 4 is used to leave space for the claws on the robotic arm to insert when the robotic arm extends downward to grab the stacked iron sheets. Since the robotic arm needs to open its claws at a certain angle before grabbing, the opening slot 4 is reserved to avoid collision between the robotic arm and the upright 2.

[0022] Side supports 5 are installed on both side walls of the upright frame 2. Cylinders 6 are bolted to the side supports 5. The output end of the cylinders 6 is locked to a connecting plate 7 by a nut. Two inserts 8 are bolted to the connecting plate 7 near the two side edges. The inserts 8 have a horizontally oriented rectangular cross-section and pass through the side walls of the upright frame 2. Rectangular openings for the inserts 8 are provided on both side walls of the upright frame 2, and sliding sleeves 9 are provided between the rectangular openings and the inserts 8. The dimensions of the slide rails in the sliding sleeves 9 match the sliders, and the sliding sleeves 9 and the inserts 8 slide together. One end of the sliding sleeve 9 is flush with the inner wall of the upright frame 2. This utility model uses the cylinder 6 to control the movement of the insert block 8, which, in conjunction with the lifting of the vertical lifting mechanism, lifts the iron plate stack 13 on the double belt conveyor 11. When the cylinder 6 retracts to its minimum stroke, the end of the insert block 8 leaves the space inside the upright frame 2. The upright frame 2 is normally located on the outer side of the end of the double belt conveyor 11. When the cylinder 6 extends to its maximum stroke, the insert block 8 does not contact the double belt conveyor 11. The extension or retraction of the cylinder 6 can directly drive the insert block 8 to slide inside the sliding sleeve 9.

[0023] Two symmetrically distributed connecting blocks 10 are provided on one end face of the support frame 2, which has an opening slot 4. Two mounting holes 12 are provided on the end face of each connecting block 10. The connecting blocks 10 are connected to the slider of the vertical lifting mechanism via bolts and mounting holes 12, thus enabling lifting operations through the vertical lifting mechanism. The working principle of the vertical lifting mechanism is that the extension and retraction of the cylinder 6 drives the chain, which, after passing through the guide wheel and rotating shaft, changes direction and drives the lifting block to rise and fall, thereby driving the connecting block 10 of this invention to rise and fall. The lower end of the opening slot 4 is lower than the lowest end of the insert block 8, and the distance between the opening slot 4 and the lowest end of the insert block 8 is not less than 3cm.

[0024] To reduce resistance when pulling out the insert 8, a chamfered structure is provided at the lower end of the insert 8 near the inner side of the upright 2.

[0025] The working principle of this utility model is as follows: The double belt conveyor 11 transports the stacked and neatly arranged iron plate stacks 13 to the end and stops. At this time, the iron plate stacks 13 at the end have entered the range of the upright frame 2. The insert block 8 is in the inserted state and stays in the initial position. After the iron plate stacks 13 at the end are stable, the vertical lifting mechanism is activated, and the chain drives the entire device to rise, thereby lifting the iron plate stacks 13 at the end. This rising process continues until the bottom of the insert block 8 is higher than the top of the remaining unlifted iron plate stacks 13. Then the rising stops and is suspended. The double belt conveyor 11 continues to operate, transporting the next iron plate stack 13 to the end and stopping. At this time, the vertical lifting mechanism control device moves down a certain distance, so that the lower end of the insert block 8 is suspended. Above the second iron plate stack 13 and within 1 cm of it, cylinder 6 retracts, pulling out the insert block 8. This causes the iron plate stack 13, supported by the insert block 8, to lose its support and fall freely onto the second iron plate stack 13 for stacking. At this time, the vertical lifting mechanism control device descends back to its initial position. When it returns to the initial position, cylinder 6 extends, inserting the insert block 8 back into the internal space of the frame 2, that is, below the second iron plate stack 13, repeating the first lifting action. This process is repeated multiple times in short lifting actions to stack multiple iron plate stacks 13 together and then lift them upwards until the robotic arm can grasp them. The robotic arm's claw is a replaceable part; a longer claw can be replaced as needed to perfectly cooperate with the device of this utility model.

[0026] This utility model uses the insert block 8 to lift and stack the stacks. Combined with the existing vertical lifting mechanism and mechanical claw mechanism, it simplifies the lifting action, reduces energy consumption, and enables the lifting of multiple stacks at once. This improves lifting efficiency, reduces the number of lifting actions, and thus extends the service life.
