Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for injecting liquid by inserting an injection nozzle into a body to be injected, and more particularly to an apparatus suitable for injecting soap liquid into a soap pad roll during soap pad manufacturing.

In order to inject a liquid into an object to be injected that is different from a container, an injection nozzle is inserted into the object to be injected, so the correlation between the insertion operation of the injection nozzle and the holding of the object to be injected is important.

In this invention, a pair of presser bars are arranged along the conveyor on the upper and lower surfaces of the conveyor that transports the object to be injected, and at least when the object to be injected passes between these presser bars, the tip of the injection nozzle is It is intended to be inserted into the body, and furthermore, when the required time for injection is determined, it can also be used when configuring an intermittent injection device that increases the injection efficiency per unit time that is not regulated by the required injection time. It is characterized by having a basic structure sufficient to form this structure.

An embodiment of the intermittent injection device of the present invention will be described with reference to the drawings.

FIG. 1 shows an intermittent injection device that intermittently transports four wool rolls 1 each to be filled with a filling material to an injection position, and fills the four wool rolls 1 simultaneously with the filling material at this position.

Attachment timing conveyor (hereinafter referred to as conveyor).

) 2, the wool roll 1 supported between the holders 19 and 19 provided at equal intervals is transferred to the right in the figure.

Parallel to this conveyor 2, four injection valves 4 lined up at the same intervals are fixed on the right side of a slide support 6 that is moved by a cam to be described later, and on the left side, four roll detectors 5 are arranged at the same intervals. be done.

An injection nozzle 3 having a radial hole 20 as shown in FIG. 2 protrudes from the conveyor 2 side of the injection valve 4 to which the injection liquid hose 18 is connected.

Due to factors such as the viscosity and volume of the injection liquid, or the injection resistance of the wool roll 1 of the object to be injected, it is not possible to reduce the time required for injection as desired. , the transfer speed of the conveyor 2 is selected so that the time is shorter than this.

The counter shaft 15 not only moves the conveyor 2 but also moves the slide support 6 in a regulated manner.

- The shaft 21, which is rotated in conjunction with the countershaft 15 through a pair of bevel gears 23 and 24, is supported by a support 11 that prevents the shaft 21 from swinging, and a lever 12 is fixed to the tip of the support 11. In the long groove of lever 12,
One end is connected to the slide support 6, and the other end is passed through a subshaft 22 having a cam follower 13, and the cam follower 13 is fitted into the cam groove 25 of the cam 14 which itself does not rotate. 25, and moves in response to the long groove of the lever 12, and moves the slide support 6 connected to the countershaft 22 to the right at the same speed as the wool roll 1. Also move it forward as it approaches.

As a result, the injection nozzle 3 is inserted into the wool roll 1, and the roll detector 5 arranged on the left side of the injection nozzle 3 in the figure simultaneously detects the presence or absence of the roll.

At the timing of inserting the injection nozzle 3 into the inside of the wool roll 1, the roll presser upper bar 16, 16 and lower bar 17
．． 17 and the wool roll 1 is sandwiched.

After the simultaneous injection of the filler from the four injection nozzles 3 to the four wool rolls 1 is completed, the slide support 6 is moved away from the wool roll 1 by the above-mentioned secondary shaft 22 and moved to the left in the figure. move in the direction.

Thereafter, the slide support 6 again moves to the right and forward, and the cam 1 performs the next filling injection intermittently.
The cam groove 25 of No. 4 is composed of a semicircular portion relative to the shaft 21 and a straight portion connecting both ends of the cam groove 25, as shown in FIG. 3, and is characterized by two types of movement patterns of the slide support 6.

A bearing unit 8 coupled to the above-mentioned subshaft 22 is attached to the lower part of the slide support 6, and this bearing unit 8 is guided and slid by a rod support extending laterally in the figure.

Vertical guides 9 extending vertically in the figure perpendicular to these rod supports 7 support the rod supports 7, and the vertical guides 9 themselves are supported by other members (not shown) so as to be able to slide in the vertical direction. Ru.

Further, it is preferable that all the detection signals of the roll detectors 5 of the four side sets are electrically stored, and the valves 4 are operated independently according to this stored information.

The injection valve 4 at the position corresponding to the roll detector 5 that did not detect the wool roll 1 is not driven.

Therefore, there is no danger that the filling will be spewed out from the injection nozzle 3.

If there is no particular requirement for a correlation between the required injection time and the transport speed of the object to be injected, one of the injection valves 4 having the injection nozzle 3 is used for one of the roll detectors 5 for detecting the presence or absence of the object to be injected. Instead of intermittent transfer and injection operations, the present invention is modified so that the objects to be injected are intermittently transferred one by one and the filler is injected into them.

As mentioned above, the presser bars 16 placed above and below the conveyor 2
．． 17 can properly hold the wool roll 1 of the object to be injected transferred by the conveyor 2, so that when inserting the injection nozzle 3 into the wool roll 1, the injection nozzle 3 can be inserted easily and reliably, and furthermore, the injection nozzle 3 can be transferred at equal intervals. If a presser bar of a length is used which governs a certain number of wool rolls 1 at a time, the same number of injection nozzles 3 as said certain number can be inserted into these rolls at the same time.

In addition, in order to control the spouting of the filling material from the injection nozzle 3, a roll detector 5 is placed on the opposite side of the injection nozzle 3 to the transport direction of the conveyor 2, so that injection can be performed when there is no wool roll 1 corresponding to the nozzle 3. The ejection operation of the corresponding injection nozzle 3 can be accurately controlled by the detection signal of the detector so that the filling material is not ejected from the nozzle 3.
