Abstract

The present invention provides a filling pipe (1) for liquid packing equipment, used to introduce the liquid filling into a longitudinal sealed cylinder of a wrapper (2), which moves forwards around the liquid filling continuously. The filling pipe of the present invention has a damping component (3), encircling the filling pipe to form a cavum. The external surface of the lower part of the damping component extends outwards along the radial direction to form a seal with an internal wall of the cylinder of the wrapper (2). The damping component is provided with a pore ensuring the circulation of the liquid inside and outside of the damping component. The filling pipe of the present invention can control effectively the change extent of the liquid level of the liquid in the cylinder of the wrapper (2). Automatic circumfluence supplements the liquid. Low pressure can also be avoided in the cylinder of the wrapper, which ensures the high speed running of the packing equipment.

Description

The filling pipe that is used for liquid packing device

Technical field

The present invention relates to a kind of filling pipe, be positioned at the continuous packing tubular article of a longitudinal sealing, be used for liquid packing device, especially on the bottle placer.By filling pipe, import liquid filler material in the packing tubular article, and, form the individual packages container through laterally involution, cutting.

Background technology

In bottle placer, packaging strip is untied from reel, is transported to chlorination equipment, and by applying a kind of chemosterilant, as hydrogen peroxide, packaging strip is sterilized processing.Packaging strip after sterilization is evaporated by force and is pushed, and surface disinfectant is removed.Then, as shown in Figure 1, packaging strip fill pipe 1 axially on move ahead, by the effect of shaped device (not shown), form ellipticity or cylindric gradually, and under the effect of sealing arrangement (not shown), two longitudinal edges overlap joint involution, promptly form packing tubular article 2, be enclosed in the above-mentioned packing tubular article 2 and fill pipe 1 with vertical envelope 22.

The front end of packing tubular article 2 advance to the open end of filling pipe 1 with upper/lower positions, the horizontal involution of sealed device (not shown) forms horizontal sealing 21.Liquid or flow-like liquid 10 as milk fruit juice, pasteurize or high-temperature treatment (UHT), grape wine etc., as shown by arrows, flow into and fill pipe 1, and in open end is introduced above-mentioned packing tubular article 2.Packing tubular article 2 continues to move ahead after the preset length, be subjected to the effect of sealing arrangement (not looking out) once more, form the horizontal sealing 21 of the other end, the tubular article that liquid 10 is housed simultaneously is under the effect of shaped device (not looking out), form preset shape, last device to be cut (not looking out) is cut off, and forms individual packages container 20.As selection, packing container 20 can be by corresponding folding and shaped device, and is folding further and form final shape, the i.e. packing container of brick shape or other shapes along folding line.

In the making of above-mentioned packing container 20, when packing tubular article 2 is formed and sealing arrangement when clamping, the liquid 10 in the tube is stopped that liquid level will rise; New packing container independently forms, and the continuation of subsequent packages material tubular article 2 is descending, and the in-to-in liquid levels descends.In the normal operation of equipment, above-mentioned circulation is repeated continuously, and the liquid level of the liquid 10 in the packing tubular article also repeats play up and down.We are normally according to the position range of detected above-mentioned liquid level, come regulating control to fill the valve of pipe 1, and the flow of filling pipe 1 is injected in control then, are filled in requirement under the friction speed thereby satisfy product.But want to guarantee that the position of detected above-mentioned liquid level is accurate, liquid 10 liquid levels must keep within limits in the packing tubular article 2, promptly can not exceed measurement range.

In addition, facts have proved that when the packaging facilities high-speed cruising, as per hour reach several ten thousand bags, the electrolyte level rangeability of liquid 10 is excessive too fast, do not have that the chien shih liquid levels relies on gravity to fall after rise when sufficiently long, liquid level detects the difficulty that will become.Therefore, during high-speed cruising, be difficult to detect effectively the actual liquid level position of liquid in the packing tubular article, also just be difficult to the flow size that pipe is filled in control.

In the packaging facilities operational process, when the packing tubular article is formed and sealing arrangement when clamping, wish to have big pressure to produce (can produce) by the damping that strengthens withdrawing fluid, to avoid the packing tubular article when forming continuous packing container 20, to produce low pressure, have a negative impact, occur defectives such as pit as packing container 20; And independently form at new packing container, the packing tubular article continues when descending, wishes to have enough big flow to replenish (can by the damping generation that reduces withdrawing fluid) again.How to properly settle the damping of withdrawing fluid, satisfy the requirement under the above-mentioned different situation simultaneously, be still the difficult problem in the filling apparatus so far.

Summary of the invention

The purpose of this invention is to provide a kind of improved filling pipe that is used on the liquid packing device, thereby improve and address the above problem, liquid levels rangeability in effective controlling packet package material tubular article, automatic backflow liquid make-up, avoid simultaneously in the packing tubular article, forming low pressure, thereby guarantee the high-speed cruising that packaging facilities is correct.

Technical scheme of the present invention is: a kind of filling pipe that is used for liquid packing device, be used for liquid filler material is imported in the packing tubular article of its longitudinal sealing that continues to move ahead, and this filling pipe has a damping piece, forms cavity around filling pipe; This damping piece is interfixed by upper and lower two individual part and forms; This top has the hole, and liquid filler material circulates up and down through this hole; Wherein, described top adopts metallic material to make; Described bottom adopts non-metallic elastic material to make, and when being subjected to hydraulic shock, outwards expand in this bottom and the inwall formation of packing tubular article is sealed and matched.

As further improvement, described bottom is stuck in the described top, both captive joints.

Use the present invention to fill the packaging facilities of pipe, can suppress liquid at work effectively and in the packing tubular article, fill the motion of pipe relatively, thereby when making high-speed cruising, the monitoring of liquid level is achieved.

Filling tubular construction of the present invention is simple, and cost is low, installation and easy to adjust, and reliable operation.By the fine tuning to hole on the adjusting of the upper-lower position of damping piece and the damping piece, the demand in the time of can being applicable to low speed and high-speed liquid can respectively.
