Description

How to drive tandem card

The drawings show an embodiment of the present invention.

1 is a schematic side view showing the roller portion of the tandem card.

2 is a schematic plan view showing a drive mechanism portion related to the roller portion.

The present invention relates to a method of driving each roller portion of a tandem card.

It is well known that this tandem card is a speech of two cards, and two carding mechanisms with heavy loads are provided in two places, so that both carding mechanisms can be started and stopped. The relationship is very important.

That is, when the tandem card is started, the sliver sending side carding mechanism (hereinafter referred to as the second carding mechanism) should be operated before the feeder side carding mechanism (hereinafter referred to as the first carding mechanism). If this operation time is out of shift, the web sent from the first carding mechanism becomes clogged in the part where the water is transferred to the second carding mechanism, so that the water supply of the smooth web does not work, and the metal wire or the cloth for carding It causes big accidents such as damage to the cloth.

In addition, the second carding mechanism having a smaller load than that of the first carding mechanism needs to be stopped first, and the web is cut between the first carding mechanism and the second carding mechanism. There is a big drawback.

In the previous tandem cards, electric motors were driven by one motor, or the conventional cardard drive mechanism was used together with each carding mechanism as it is. Because of this size, it is difficult to reliably time the two carding mechanisms to work together.

Therefore, each carding device is driven by a separate motor, and another dispensing device or water supply device is driven by a third motor. However, this makes the whole tandem card not only large and complicated, but also complicated operation. It also had the drawback of being very expensive.

In the previous tandem cards, since the linkage between the feed rollers and the second carding mechanisms after the web was passed was not considered at all, even if the feed rollers were rotated to supply the raw materials. If the next process is stationary, the surface will still be blocked and cause a big accident.

The present invention eliminates many of the shortcomings of the previous tandem cards, and the simple and inexpensive driving mechanisms drive each carding mechanism with large load at start and high inertia at stop, while driving both mechanisms smoothly and safely. It is intended to provide a driving method that allows the carding operation to be performed well by controlling the interoperation time of the drive properly and preventing the blockage or the accident caused by it.

Hereinafter, one embodiment of the present invention will be described with the tandem card shown in the drawings. In other words, the tandem cardard removes a second carding mechanism including a second taker roller-in roller 12, a second cylinder 13, and a second rotating flat 14 at start and stop. Since the first carding mechanism and feed roller (1) consisting of the roller (3), the first cylinder (4), and the first rotating flat (5), which are one taker, are driven or stopped before starting the tandem card, First, when the second motor 67 installed on the sliver sending side shown in FIG. 2 is driven, the second cylinder 13 passes through the pulley 68, the belt 69 and the pulley 70, and the pulley. The roller 12 which is a 2nd taker rotates through 71, the belt 72, and the pulley 73, respectively.

Then, after driving of the second carding mechanism, the first motor 24 on the surface supply side is adjusted and started, and the first cylinder 4 passes through the pulley 25, the belt 26, and the pulley 27. Then, through the pulley 27, the belt 29, and the pulley 30, the roller 3, which is the first taker, rotates at a predetermined speed, respectively, and in this connection, the axial pulley 31 of the roller 3 is connected. And the endless transmission 33 is operated via the belt 32, the pulley 28, and at the same time the pulley 36 'and the pulley 28' and the belt 34 on the shaft of the transmission 33. The transmission shaft 37 rotates together with the electronic clutch 35 to which the is attached. As a result, the gear 41 rotates via the first gear train 38 consisting of three gears connected to the transmission shaft 37, the second gear train 39 consisting of three gears, and the gear 40. And a first bevel gear consisting of a third gear train 43 of three gears and two bevel gears in which a first doffer 6 rotates and is connected to the gear 41 via a gear 42. Since the worm 45 rotates via the row 44, the feed roller 1 rotates via the worm wheel 46 engaged with the worm 45, while the worm 45 rotates through the row 41. The first crushing roller 9 is rotated through the sprocket 47, the chain 48 and the sprocket 49 on the shaft of the gear 74, and the roller 9 is rotated. The transmission mechanism 52 is rotated with respect to the first crushing roller 9 while the two transfer rollers 10 and 11 rotate respectively through the transmission mechanisms 50 and 51 such as each sprocket or each chain.The first water roller 8 and the first stripping roller 7 connected via the gear train 53 rotate with respect to the roller 8.

Although not shown, the rotation flat 5 on the first cylinder 4 and the rotation flat 14 on the second cylinder 13 are pulleys 27 and axially on the cylinders 4 and 13, respectively. Driven by a drive mechanism connected thereto.

As described above, the first carding mechanism, the feed roller 1 and the first doper, the first stripping roller 7, the first water roller 8, and the first size are driven by the first motor 24. A second bevel gear train line 54 consisting of two bevel gears connected to the second gear train 39 while the web water roller group consisting of the rushing roller 9 and the transfer rollers 10 and 11 rotates. Since the gear 57 is driven to rotate via the 55 and third bevel gear trains 56, the second doffer (on the second carding mechanism side having the gear 58 meshed with the gear 57) 15 is rotated, and the second crushing roller 18 is rotated in a pair of up and down via the sprocket 59, the chain 60 and the sprocket 61 on the gear 75 shaft engaged with the gear 58. At the same time, the second water roller 17 connected to the roller 18 via the transmission mechanism 62 and the second stripping roller 16 connected to the roller 17 via the gear train 63 are respectively formed. On the other hand, the fourth gear train 64 consisting of three gears connected to the gear 76 engaged with the gear 58, the fourth and fifth bevel gear trains 65, 66 consisting of two bevel gears. And two sets of top and bottom draft rollers 19 and one set of right and left calendar rollers 20 rotate through an appropriate delivery mechanism (not shown).

The coiler tube 21 and the coiler wheel 22 shown in FIG. 1 are operated by an appropriate coiler motion device (not shown).

Since the tandem card of the present embodiment is driven by the driving mechanism as described above, the surface L during the tandem card operation is the feed roller 1 on the dish plate 2 as shown in FIG. After the carding action with the roller (3), the first cylinder (4), the rotating flat (5) and the first doper (6), which are the first takers, respectively, the first strip as the web (W) Deodorized by the pin roller (7), and the second take-in roller (12), the second cylinder (13), the rotating flat (14) and the second doffer (15) via the water roller group. In this case, the carding action is performed again, and then deodorized to the second stripping roller 16, and then passed to the second water roller 17 and the second crushing roller 18 to become a sliver S and a draft roller ( 19) and in turn into the can 23 via the calendar roller 20.

The drive mechanism associated with the first motor 24 is called a first drive mechanism, and the drive mechanism associated with the second motor 67 is called a second drive mechanism.

In the case of stopping the tandem card as described above, in the case of stopping, first the second motor 67 is stopped to stop the second driving mechanism on the side of the second carding mechanism, and then the first motor. (24) is appropriately adjusted and stopped to stop the electric bulb driving mechanisms other than the second driving mechanism, that is, the first driving mechanism and the rollers associated with the mechanism, respectively.

Therefore, the first drive mechanism with a large resistance and a short stop time and the second drive mechanism with a long stop time can be made almost the same with a stop because the resistance is small. Further, in the above embodiment, since all of the feed roller or web water roller group relationships are driven by the gears or sprockets and the chain, the relationship between the rollers can be reliably driven and quickly shifted to the normal operation state. You can stop the rollers all at once.

As described in detail in the above-described embodiment, in the tandem card having a carding mechanism of a plurality of devices, the second carding is performed by one driving motor separately from the driving mechanism of each carding mechanism. It is a driving method for driving the cylinder, take-in roller and the rotating flat of the mechanism, the cylinder on the side of the first carding mechanism, the take-in roller, the rotating flat, the feed roller and each required roller by the other drive motor, On the first driving part side, even if the load at the start and the inertia at the stop time become large, the second driving part is considered to be as small as possible, so that it can be easily driven when necessary, so that the previous tandem card driving method and In comparison, the carding mechanism can be started and stopped more smoothly by simple and inexpensive driving means. Both the important and necessary parts of the carding mechanism can be easily and precisely selected at the start and stop of the carding mechanism. This disappears and can perform stable carding.
