Description

Tubular material pulling 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, one process is added and labor costs are increased.

Compared with the packaging process of the above-mentioned 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 price.

However, the tube-shaped packaging form is very different from the sheet-shaped packaging form. The packaging material in the sheet-shaped packaging form can move forward continuously, while the packaging material in the tubular packaging form does not complete the previous packaging. It does not move forward when the previous packaging is completed, and the tubular packaging material must be moved forward immediately so that the open end can be accurately transported to the discharge port. Sheet-shaped packaging materials only need to move one to meet the packaging speed requirements, while tube-shaped packaging materials need to move more than 4 packaging materials at the same time to meet the packaging speed requirements.

Chinese patent 200820162608 is a packaging bag support device for an automatic packaging machine for disposable syringes. The method of pulling the tube is to adsorb the tubular material on a rotating object, and the tubular material moves upward with the rotation of the object. There are no convincing instructions for ensuring accurate movement of tubular material during operation. At the same time, the adsorption device must always run, which inevitably consumes a lot of energy.

The embodiment among the above-mentioned accompanying drawings has 5 internal support pits and clamps, and 5 only represent that the embodiment of the present invention is multiple, and other embodiments can be greater than or less than 5.

The action of each component in the embodiment can be completed by selecting electric or pneumatic components. For the sake of brevity, the power supply and power are not described and explained in the figures and below.

Detailed ways:

Referring to accompanying drawing 1, the partially enlarged side view sectional schematic diagram of the initial state of the practice example.

Because of the side view, only one image of the initial state of the tubular material is shown in the figure.

It is shown in the figure that the coiled tubular material 51 is under the inner support pit 11, the open end 52 of each tubular material 50 is above the inner support pit 11, and the inner support 20 is in the open end 52 of the tubular material 50, The inner support 20 is placed on the inner support pit 11.

The inner support pits 11 are arranged on the inner support base 10 in the form of a column, the mouth of the inner support pits 11 is upward, and the inner support pits 11 are directly below the discharge opening 60 .

The pipe puller 30 is made up of a clamp 31 and a lifter 33. There are several clamps 32 on the clamp 31. The number and position of the clamps 32 on the clamp 31 are the same as the number and position of the inner support pit 11.

The clamps 31 are opened and closed in the horizontal direction, and when the clamps 31 are opened or closed, all the clamps 32 act simultaneously.

In the figure, the clamps 31 in the opened state are on both sides of all inner support pits 11 , that is, on both sides of all inner supports 20 .

The clamp 31 is connected with the lifter 33 , the clamp 31 can be raised and lowered, and the clamp 31 moves up and down along the guide rail 34 between the top of the inner support 10 and the bottom of the discharge port 60 .

The height detector 40 is connected with the elevator 33, and the height detector 40 sends height information after the clamp 31 reaches the set height, and after the height detector 40 sends the height information, the elevator 33 stops moving.

Referring to accompanying drawing 2, accompanying drawing 2 is the top view schematic diagram of the initial state of the practical example.

Shown in the figure are 5 clips 32 and 5 inner support pits 11 arranged side by side, they are arranged in a column to form 5 packaging units, the number of the packaging units only represents that the packaging unit of the embodiment of the present invention can be Multiple, other embodiments may be greater or less than 5 packaging units.

The number and position of the clamps 32 are the same as those of the inner support pit 11, that is, a clamp 32 is on both sides of an inner support pit 11, because an inner support 20 is inside an inner support pit 11, that is, a clip Members 32 are on either side of an inner stay 20 .

Therefore, when the clamp 31 is closed, all the clamps 32 can be closed and clamped all the inner supports 20 at the same time. Because all of the inner stays 20 are within the open end 52 of the tubular material 50 , clamping the inner stays 20 also means clamping the open end 52 .

Referring to accompanying drawing 3, accompanying drawing 3 is the first step of device operation, and the clamp 31 begins to close, and is ready to clamp the schematic diagram of opening end 52.

The clamp 31 is closed inwardly in the direction indicated by the arrow, and clamps all the inner stays 20 in the open end 52 . Because the open end 52 is in the middle of the clip 32 and the inner support 20 , the clip 32 clamps the inner support 20 , which also means that the open end 52 is clamped.

Referring to accompanying drawing 4, accompanying drawing 4 is the 2nd step of device operation, and the schematic diagram that fixture 31 begins to move upward along guide rail 34.

After the clamps 31 were closed inwardly, the inner supports 20 clamped on all the inner support pits 11 began to move upwards. When the clamps 31 moved upwards, the tubular material 50 was also pulled upwards simultaneously because the open end 52 moved upwards.

The height detector 40 detects the marking 53 on the tubular material 50 when the tubular material 50 is moving, and sends height information when the height detector 40 detects the marking 53, and the elevator 33 stops moving.

It can be seen from the above practical examples that the pulling of the tubular material 50 is carried out under the condition that the open end 52 is opened, and the pulling speed and accuracy of the tubular material 50 are completely controllable.
