Description

Technical Field

[0001] The utility model relates to a product case packing machine, which relates to the technical field of product case packing. Background Art

[0002] At present, in the field of automatic boxing technology, the boxing method generally adopted by technicians in this field is to complete the boxing by moving the product after positioning the box. Specifically, after the box is positioned, the product is grabbed by a robot and placed in the box, or the product is pushed into the box by a push-pull mechanism. These two boxing methods need to meet the following requirements when implemented: first, the product outer packaging has a standardized shape and uniform dimensions; second, the product outer packaging material has high hardness and is not easy to be damaged.

[0003] However, the above two packaging forms are not suitable for the packaging of medical hose products. The reason is that in order to facilitate disinfection, medical hose products usually use an outer packaging with an upper layer of breathable paper and a lower layer of plastic film bags. However, products packaged in this outer packaging usually have the following problems during packaging:

[0004] 1. There is gas in the bag. When the robot grabs the product for packing, the robot will use too much force to grab the bag, which will cause the bag to burst. The force of the robot is not easy to control. If the force is too small, the product will fall during the transportation process.

[0005] 2. Use a suction cup to absorb. First, the breathable paper surface cannot be sucked because it is breathable. Second, the product shape is irregular, which makes the plastic film surface uneven and the suction cup cannot suck it.

[0006] 3. When the robot is used to grab the product, a certain closing force needs to be applied to ensure that the product does not fall off the robot, which causes the product to contact with the robot's grabbing surface, resulting in the extrusion of the plastic film between the two, resulting in damage and scratches;

[0007] 4. When pushing the products into the box through the push-pull mechanism, the direction of the products needs to be kept consistent. That is, when packing multiple sets of products, the upper breathable paper must be oriented in the same direction. However, when using a push-pull mechanism, there is friction resistance when pushing and pulling, which can easily cause the packaging bag to be squeezed. In addition, there is gas expansion in the bag, and the products arranged in a row will change in size due to the expansion of the bag. Therefore, the plastic film surface of the product packaging bag at the end will be squeezed against the surface of the push-pull mechanism, resulting in scratches on the plastic film surface of the packaging bag.

[0013] The lifting and box-taking conveying mechanism is located directly below the product storage and box-pulling mechanism; the lifting and box-taking conveying mechanism includes a horizontal conveying line and a conveying drive motor connected to the horizontal conveying line, the horizontal conveying line and the conveying drive motor are connected to a vertically arranged lifting cylinder, and the lifting cylinder is installed on the lifting and box-taking conveying mechanism frame.

[0014] Preferably, the pulling-in mechanism includes electric push rods for taking out empty boxes, which are symmetrically arranged on both sides of the front opening of the product storage cavity and placed in the horizontal direction. The ends of the electric push rods for taking out empty boxes are vertically connected to a vertically arranged movable plate. A positioning cylinder and a suction cup driven by the positioning cylinder are installed on the movable plate. The suction cups on both sides are arranged opposite to each other and are used to adsorb the two sides of the empty box.

[0015] Preferably, the front end of the electric push rod of the emptying box passes through the center of the fixed plate and is connected to the movable plate. The fixed plate is fixedly installed on both sides of the front opening of the product storage cavity. A guide shaft hole is provided on the fixed plate.

By using the cartoning machine provided by the present invention, the entire cartoning process can effectively avoid the situation where the film bags between the products are scratched due to the relative movement between the products in the bag and the limiting surface. At the same time, in addition to the gravity of the product itself, no other external force acts on the packaging bag during the entire cartoning process, thereby avoiding the problems of external force causing the packaging bag to expand and explode, and the bag swelling causing a row of sizes to become larger and squeezed.

[0030] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] A product packing machine includes a packing machine frame 500, in which a product presence and box pulling mechanism 100 and a lifting and box taking and conveying mechanism 200 are integrated, wherein the packing machine frame 500 is used to support the product presence and box pulling mechanism 100; the product storage cavity 102 of the product presence and box pulling mechanism 100 is used to store products, and a pulling mechanism is provided at the front opening of the product storage cavity 102, which is used to grasp an empty box 600 and pull the empty box 600 into the product storage cavity 102; the lifting and box taking and conveying mechanism 200 is used to convey the empty box 600 and control the lifting and lowering of the empty box 600.

[0032] In the product storage and box pulling mechanism 100, the empty box 600 is arranged on the opposite side of the product storage cavity 102, and the front side of the product storage cavity 102 is open and arranged opposite to the opening of the empty box 600; the pulling mechanism is arranged at the front opening of the product storage cavity 102, and the pulling mechanism is used to grasp the empty box 600 and pull the empty box 600 into the product storage cavity 102; rotating shafts are symmetrically provided on the left and right sides of the product storage cavity 102, and the rotating shafts are installed on the case packing machine frame 500, one side of the rotating shaft is drivingly connected to the flipping mechanism, and is used to flip the empty box 600 downward 90°, and the flipping mechanism is installed on the case packing machine frame 500.

[0033] Furthermore, the product storage cavity 102 is a semi-enclosed cavity composed of four surfaces, and the semi-enclosed cavity has openings in two directions, wherein the opening in one direction is the front opening before flipping, and the opening in the other direction is the upper opening before flipping. Before the product storage cavity 102 is flipped, the products are stacked vertically in the product storage cavity 102, and the placement direction of each product is required to be consistent, so that only one side of a vertical row of products will have a film surface in contact with the limiting surface, and the other side is a paper or other non-wearable material surface and the limiting surface will move relative to each other, but no scratches will appear. The four surfaces of the product storage cavity 102 are used to limit the product. The front opening is designed to face the opening surface of the box body, and the product can enter the box body through this surface. The upper end opening is designed to avoid relative movement between the film wear-prone surface and the limiting surface.

[0034] Furthermore, the pulling-in mechanism includes electric push rods 103 for taking out empty boxes, which are symmetrically arranged on both sides of the front opening of the product storage chamber 102 and placed in a horizontal direction. The ends of the electric push rods 103 for taking out empty boxes are vertically connected to a vertically arranged moving plate 104. A positioning cylinder 105 and a suction cup 106 driven and connected to the positioning cylinder 105 are installed on the moving plate 104. The suction cups 106 on both sides are arranged opposite to each other and are used to adsorb the two sides of the empty box 600.

[0035] Furthermore, the front end of the electric push rod 103 for removing the empty box passes through the center of the fixed plate 108 and is connected to the movable plate 104. The fixed plate 108 is fixedly installed on both sides of the front opening of the product storage cavity 102. A guide shaft hole is provided on the fixed plate 108, and a horizontally arranged guide shaft 107, one end of which slides in the guide shaft hole, and the other end of which is fixedly connected to the movable plate 104.

[0036] Furthermore, the flipping mechanism includes a box flipping connecting rod 400, one end of which is connected to the one side rotating shaft, and the other end of the box flipping connecting rod 400 is drivingly connected to the box flipping electric cylinder 300, and the box flipping electric cylinder 300 is horizontally installed on the box packing machine frame 500.

[0037] The lifting and box-taking conveying mechanism 200 is located directly below the product storage and box-pulling mechanism 100; the lifting and box-taking conveying mechanism 200 includes a horizontal conveying line 203 and a conveying drive motor 204 driven and connected to the horizontal conveying line 203, the horizontal conveying line 203 and the conveying drive motor 204 are connected to a vertically arranged lifting cylinder 202, and the lifting cylinder 202 is installed on the lifting and box-taking conveying mechanism frame 201.

[0038] The process of taking empty boxes; refer to the attached Figure 7 , the empty box 600 is transported by the transmission line to the box taking position of the packing machine and reaches the required position. At this time, the packing machine is in Figure 1 In the state shown, the opening direction of the empty box 600 is opposite to the opening direction of the product storage cavity 102 in the product storage and box pulling mechanism 100; after the empty box 600 stops in place, the empty box electric push rod 103 in the product storage cavity frame 101 is in Figure 3 In the extended state shown, it extends to the middle position of the rear end of the box body, and the positioning cylinders 105 on both sides extend forward and make the suction cups 106 on both sides contact the two sides of the box body. The suction cups 106 on both sides suck air and hold the empty box 600, thereby completing the box grabbing function. At this time, the opening of the empty box 600 is completely aligned with the product storage cavity; then, the electric push rod 103 for taking the empty box contracts and pulls the empty box 600 to the required position. When the electric push rod 103 for taking the empty box contracts into place, the empty box 600 has completely covered the product. The product reaches the bottom of the empty box 600 and contacts the front open surface of the product storage cavity 102. At this time, the product has completely entered the empty box 600. During the process of taking the empty box and pulling the box, the product has no contact with all moving surfaces.

[0039] Product packing process: after the empty box push rod 103 is retracted into place, the box flipping electric cylinder 300 drives the box flipping connecting rod 400 to move by contraction, so as to convert the linear motion of the box flipping electric cylinder 300 into the rotational motion of the product storage chamber 102. After the box flipping electric cylinder 300 is retracted into place, the product storage chamber 102 rotates downward 90°, and the front opening of the product storage chamber 102 changes from the vertical position before the flipping to the downward horizontal position after the flipping. At this time, the main open surface of a vertical row of products has been supported by the bottom surface of the box, and the other open surface is limited by the side surface of the box, and the remaining non-wear surfaces are limited by the product storage chamber; after the product storage chamber 102 rotates into place, the lifting box conveying mechanism 200 directly below performs a lifting action, wherein the conveying line 203 is lifted by the lifting cylinder 202. After the product is lifted into place, the conveyor line 203 contacts the bottom of the box above to complete the flipping action. After the product exists and the box pulling mechanism receives the signal that the lifting cylinder 202 is lifted into place, the solenoid valve is used to control the suction cup 106 to disconnect the adsorption of the box, and then the empty box electric push rod 103 is retracted. The contraction of the empty box electric push rod 103 drives the product storage chamber 102 to separate from the box and the product, and the product stays in the box under the action of gravity, thereby completing the product entry. During this process, there is no relative movement between the plastic film surface of the product packaging bag and its limiting surface; when the product storage chamber 102 is completely separated from the product and the box, the lifting cylinder 202 descends, and the conveyor line 203 carrying the box containing the product descends to a position horizontal to the lower end conveyor line, and finally the conveyor drive motor 204 drives the conveyor line 203 to convey the product to the downstream conveyor line.
