Description

[Detailed Description of the Invention] The present invention relates to a device for compressing sliver and storing it in a can in a spinning machine such as a filament machine or a carding machine, thereby increasing the capacity of the can.

Various devices have been considered for increasing the capacity of sliver, and one type of such device is one in which a press rod that receives the bottom plate of the can gradually descends inside the can as the sliver is compressed and accommodated. The pressing rod is detachable from the bottom of the can.

On the other hand, as the coiling position is changed between a full can and an empty can, it is necessary to take out the full can from the can exchange passage and replenish the empty can to the passage. It is also desired to reduce the burden on workers by not increasing the cost too much.

Therefore, in the above-mentioned type, a hole is dug from the floor surface to a depth corresponding to the amount of elevation of the press rod.

In this way, when a pressure rod that receives the bottom plate of the can is used, and a hole is dug under the floor with a depth approximately equivalent to the amount by which the can is raised and lowered over the entire length of the can, the amount of elevation of the pressure rod is the same as the amount of elevation of the bottom plate of the can. It is easy to control, and the can exchange passage can be relatively low.
This has the advantage of simplifying the mechanism, which is preferable, but one of the previously considered elevating mechanisms for this type of device is a rotation drive using a driving wheel, as in the case of Utility Model 125512 (1972). There is one in which a part of the cheno is connected to a pressure rod.

In this case, the press rod descends by a constant amount as the driving wheel rotates at a constant rate, regardless of fluctuations in the spinning weight, so there is a drawback that the surface pressure is unstable and the sliver storage density is not uniform.

At the same time, in order to adjust the descending speed of the press rod, it is necessary to change the rotation speed of the driving wheel or replace it with one of a different diameter.Furthermore, after the can is full, the press rod must be rapidly lowered and the drive wheel must be moved from the bottom of the can. A drive system is required to provide variable speed rotation to the drive wheels when the lift is removed from the floor, and the hole dug under the floor becomes large, which is inconvenient for use as an elevator mechanism.

In order to solve this problem, a pneumatic circuit was adopted as in Utility Model Application No. 52-18222, and when the repulsive force of the sliver exceeds the surface pressure (set pressure) received from the bottom plate, the press rod gradually moves while maintaining the predetermined surface pressure. It is also being considered that a structure that descends to

In this case, since the pressing rod descends depending on the repulsive force of the sliver, the sliver is housed uniformly in a sufficiently compressed state, and the descending speed of the pressing rod can be easily adjusted by changing the set pressure. Furthermore, the rapid lowering of the press rod after the can is full can be achieved by simply controlling the air in and out of the lifting air cylinder, and the control circuit is simple.

However, in the aforementioned Utility Model Application No. 52-18222, the other end of the chino, one end of which is connected to the piston rod of the lifting air cylinder, is fixed to the circumferential surface of a small drum fixed to the -shaft, and the large drum is also fixed to the shaft. This large drum had a drawback because the ceno, which was connected to the press rod, was fixed to the circumferential surface of the large drum.

Firstly, the large drum requires a circumferential length equal to the amount of lift of the press rod, so the diameter is usually about 300 mm.
If this was installed on the floor, the can exchange passage would be pushed up to a considerable height, and if this was to be avoided, a hole would have to be dug in the floor to accommodate the large drum, which is undesirable in any case.

Second, since the small and large drums are each equipped with independent chains, the amount of lift of the press rod changes due to the length of each chain, which reduces sliver storage performance. do.

The device of the present invention is of a type that accommodates sliver by raising and lowering a press rod that receives the bottom plate of the can, and in order to take advantage of the advantage of a pneumatic circuit, an air cylinder is used as the mechanism for lifting and lowering the press rod. An air cylinder is installed below, a Cheno pulley is attached to the tip of the piston rod, and a Cheno pulley with one end fixed at the most advanced position of the piston rod or a fixed position in front of it is hung on the boot, and the other end of the Cheno The end is connected to the lower end of the press rod via a guide pulley, and as a result, the can exchange path is maintained at a low position, and fluctuations in the amount of elevation of the press rod due to the extension of the ceno are kept to a minimum. Furthermore, the stroke of the piston rod can now be limited to half the amount of elevation of the presser rod, making the device as a whole more compact.

The device according to the invention will be described below with reference to the embodiment shown in the drawings.

There is a can table 3 for receiving the can 2 at the bottom of the wire-stretching machine body 1, and the can 2 can be rotated by applying rotation to a gear 5 that is part of the can table drive mechanism 4. The tube 8 of the coiler wheel 7 is inserted into the rotating can 2 from the upper calender roller 6 to the coiler wheel 7.
A press rod 10 having a press plate 31 at its tip for receiving the can bottom plate 9 is provided passing through the can table 3 to accommodate the sliver fed out through the can table 3.

This pressing rod 10 needs to move the can bottom plate 9 up and down over the entire length of the can and also transmit rotation.For this purpose, a hole 12 with a depth corresponding to the length of the can is first dug from the floor surface 11. 10, the guide rod 1 is connected from the Kenstable support mechanism 13 so that the lower end can be supported at all times.
4 is vertically installed along the hole 12.

In this case, the support bracket 36 for receiving the lower end of the press rod engages with the guide rod 14 via the guide roller 15, so that the press rod 10 can be smoothly raised and lowered along the rod 14.

Further, the configuration for transmitting the rotation of the can table 3 to the press rod 10 is as shown in FIG.
The pressure rod 10 is held between all sides by support rollers 16 mounted on a bracket 37 fixed to the frame, and the rotation of the bracket 37 caused by the rotation of the can table 3 is applied to the pressure rod 10 by the clamping force of the support rollers 16. At the same time, the lifting and lowering action of the press rod 10 is transmitted to the support roller 16.
rotation.

Now, in the push rod 10 support mechanism and rotation transmission mechanism configured as described above, in order to transmit the vertical movement to the push rod 10, the present inventor assumes that the air cylinder 17 is adopted due to the advantage of control using a pneumatic circuit. The discussion was made from the viewpoint of how to install the air cylinder 17 and how to connect the piston rod 18 and the press rod 10 of the air cylinder 17 to obtain a desirable sliver capacity increasing device as a whole.

We have focused on the fact that a space S is formed between the can exchange passage 19 and the floor surface 11 due to the presence of the can table 3, its drive mechanism 4, and support mechanism 13.

In other words, a can exchange passage 19 for juxtaposing full cans 2a and empty cans 2b is formed between the coiling position cans 2 so as to be close to and flush with the upper surface of the can table 3. A small space S will be created between them.

Therefore, first, the air cylinder 17 is placed in the space S on the floor surface 1.
Next, a Cheno pulley 21 is attached to the tip of the piston rod 18, and a Cheno pulley 21 is installed on the receiving plate 20 installed along the piston rod 18. , the chaino 23 is hung on the chino pulley 21, and the chino 23 is folded back, and the chino 23 is hung on the guide pulley 26 attached to the bracket 25 on the receiving plate 24 and the guide pulley 27 attached to the support mechanism 13, respectively. It is connected to the bracket 36.

By configuring the push rod lifting mechanism in this way, the stroke of the piston rod 18 can be made half the lifting amount of the push rod, the diameter of each boob IJ 21, 26, 27 can be arbitrarily selected, and further Since only one chino is required, fluctuations in the amount of lifting and lowering of the press rod due to the extension of the chino can be minimized.

When the sliver is to be accommodated in the can 2 at the coiling position, when pressurized air flows in from the flow path A via the solenoid valve 28, the piston rod 18 is retracted, so the press rod 10 rises and rolls the can. 9 is pressed against the coiler wheel 7.

When the sliver storage starts and the repulsive force of the sliver against the bottom plate 9 exceeds the set pressure of the regulator 29, the flow path A
The air flowing backward is discharged from the regulator 29, allowing the pressure rod 10 to descend.

By repeating this phenomenon, the sliver is compressed and stored in the can 2, and when the auto counter commands a full can, the operation of the machine stops, and the solenoid valve 28 is switched to allow pressurized air to flow in from the flow path B. At the same time, the flow path A is opened, so the piston rod 18 is rapidly displaced.

Due to this displacement, the push plate 31 which had been stopped slightly above the can positioning 30 suddenly descends, burying the can positioning 30 from the upper surface of the can table 3 and pushing the push plate 31 downward.
is similarly buried in the can table 3, leaving the can bottom plate 9 in the can 2.

In this state, the can exchange operation will proceed.

In addition, in the case of a wire line machine, there are usually two deliveries, so a push rod lifting mechanism may be installed independently for each delivery, but as shown in Fig. 3, one air cylinder 17 is used and the piston It is also possible to attach a bar 32 to the rod 18, and to attach to both ends thereof a Cheno pulley 21.21 on which a Cheno 23.23 connected to each pressure rod 10.10 is mounted.

In this case, in order to stabilize the bar 32, a vertical regulating roller 33 in contact with the regular plate 20 and left and right regulating rollers 35, 35 in contact with the rails 34, 34 are attached.

As described above, the device of the present invention moves a lifting mechanism including an air cylinder around a pulley attached to the tip of the piston rod of the air cylinder, in which a chino with one end fixed in a fixed position is rotated in a space above the floor. In addition, since it is installed so that it is connected to the push rod via a foldable guide pulley, the size of each pulley can be made arbitrary, and therefore the can exchange passage can be placed at a height above the floor. Since the piston rod can be set at any position, the work of discharging full cans and replenishing empty cans from the can exchange passage does not place a large burden on the operator, and the stroke of the piston rod is only half the lifting distance of the pusher rod. The installation space for the cylinder can be reduced, and since the pressure rod and the piston rod are connected by a single chain, fluctuations in the amount of elevation of the pressure rod due to the extension of the chain can be kept to a minimum.
