Description

Inclined discharge device for tubular material packaging

Technical field:

The invention relates to a pillow packaging machine, in particular to a packaging method for tubular materials.

Background technique:

The existing pillow packaging method is to first seal the left and right sides of the sheet-shaped packaging material from the longitudinal direction to form a cavity, and at the same time place the items to be packaged in the cavity, and then place the items to be packaged in the cavity. The cavity is sealed and cut off at both ends, and it is called pillow packaging because it looks like a pillow after packaging. The whole packaging process has a high degree of automation and high speed, and is suitable for bulk, granular, powdery, and liquid objects, such as biscuits, egg yolk pies, chocolate, bread, instant noodles, moon cakes, soybean milk, milk, soy sauce, cooking wine, lotus root starch and other foods , As well as the packaging of various daily necessities, various industrial parts, various medical equipment and other objects, many patents and expertise have been produced around the pillow packaging machine.

This kind of sheet material is sealed into a cavity structure, and the items to be packaged are put into the cavity for packaging. It is an ideal form of pillow packaging. However, this form of packaging also has the following disadvantages 1. waste materials, the existing pillow packaging machine is to pack after sewing the left and right sides of the sheet packaging material, and the sewing part will waste quite a lot of packaging materials. 2. Affects the appearance. The stitched seams remain on the outside of the package and affect the appearance of the package. 3. This form of technology requires the packaging material to be a multi-layer composite material, and the multi-layer composite material is expensive. 4. Compared with the pillow packaging of tubular materials, a process is added, which increases energy consumption and labor costs.

Compared with the above-mentioned packaging process of sheet materials, the packaging process of tubular materials does not require multi-layer composite materials, and there is no intermediate stitching part, which has the advantages of material saving, beautiful appearance, energy saving and low cost.

However, compared with the sheet-shaped packaging form, the tube-shaped packaging form has a great difference in the shipping process of the package. 1. The sheet-shaped packaging form can put multiple packages into one packaging material first. In the process of moving forward horizontally, front and rear sealing, cutting and output are carried out intensively, and the shipment of sheet-like packaging can be carried out after moving forward, that is, packaging and shipment are carried out at different positions. The tubular packaging form is that after the transparent vertical tubes are fed and sealed, they cannot be dropped vertically. The vertical drop will affect the next process, that is, after the packaging is completed, the packaged products need to be Change the location to ship.

2. The packaging material in the form of sheet packaging can move forward continuously, and only one piece of packaging material in sheet shape can be moved to meet the packaging speed requirements. In the tubular packaging form, the next process can only be carried out after the previous package is shipped, so it is necessary to complete more than 4 shipments at the same time to meet the speed requirement. It is a troublesome problem how to make the finished packaging smoothly enter on the conveyor belt.

Chinese patent 2008100634552 The feeding device of the packaging bag of the automatic packaging machine of disposable syringes, the method of rotary discharge proposed in patents such as the automatic packaging machine of 200820162320.7 disposable syringes, its problem is that the structure is complicated.

Invention content:

The purpose of the invention: to provide a kind of inclined delivery device for the tubular material packaging that sends the packed packaging bags under a discharge port to the conveyor belt at the same time.

Solution: On both sides of the packaging bag under the outlet, set a gripper that can be opened or closed, tilted or reset. There are holding parts on the holder with the same number and position as the outlet. When the holder is closed, each holder can hold a packaging bag, and the holder can be rotated into an inclined state.

When running, firstly, the gripper is closed, and each gripper holds a package from the outside of the packaging bag; secondly, the gripper rotates into an inclined slide; then, the gripper releases the package, The packages are dropped onto the output conveyor along the inclined grippers, and finally the grippers return to a vertical shape.

The present invention is realized as follows: the inclined delivery device for tubular material packaging includes a discharger, a gripper, a rotator, a conveyor belt, a packaging bag, and a package;

There is a discharge port on the discharge device, and a packaging bag for entering the package is fixed under each discharge port;

The gripper is connected with the rotator, and there are several grippers on the gripper, the grippers can be opened or closed, and each gripper can hold a packaging bag when closed;

Its characteristics are: the outlets are arranged in a column, the mouth of the outlet is downward, the holder is below the outlet, a holder is corresponding to both sides of a packaging bag, and the conveyor belt is under the holder. The position of the conveyor belt is not directly below the discharge port, the grip is opened or closed in the horizontal direction, and the grip can be rotated into an inclined slide shape.

Wherein, the gripper is inclined towards the direction of the conveyor belt.

The invention has the advantages that the structure is relatively simple, the gripper clamps the packaging bag to press out the air in the packaging bag, and the packaging bag can only slide to the conveyor belt along the inclined gripper.
