2. Description of the Related Art A thread-like sliver supplied to a roving machine is twisted by passing between a plurality of sets of a top roller and a bottom roller. Yala cloth is provided. The cotton wool adhering to the surface of the endless clearer cloth is scraped off with a comb. The comb is reciprocated intermittently in the running direction of the endless clearer cloth, and actively scrapes off the lint with the tip blade during forward movement. This reciprocating motion is performed by a comb reciprocating device having a small motor and a cam mechanism. Several sets of endless clearer cloths of the roving machine are housed together in a case to prevent dust and to prevent scattering of the comb debris. 2. Description of the Related Art A comb dust suction device that sucks and discharges air from a suction port provided in a case to automatically process scraped comb dust is formed. A large number of endless clearer cloths are provided for each supply sliver, so a large number of endless clearer cloths are provided, and one set of the case, suction port and piping from the suction port are provided for several sets of endless clearer cloths. Since the number of sets is large, the pipes are joined by a duct, and the comb waste is led to the dust collecting section.

[Problem to be solved by the invention] The capacity of the blower for sucking comb debris of all roving machines installed in the factory,
That is, since the motor capacity becomes considerably large, it is uneconomical to suck at the same time. If the selection is made for each case, the motor capacity does not need to be increased, so that a method of selectively sucking is conceivable. However, even if the motor capacity can be rationalized, the selection device was inevitably complicated and expensive. Therefore, the present invention provides a comb debris suction device capable of easily performing the selection with a simple structure.

FIG. 1 is a side sectional view of a roving machine 1 having a comb waste suction device 2, FIG. 2 is a plan view of a main part of the comb waste suction device 2, and FIG.
FIG. 4 is a sectional view taken along the line III-III in FIG. 2, FIG. 4 is an explanatory view of a state of communication with the suction port 24 of the roving machine 1 having the comb waste suction device 2 and air piping, and FIG. It is a perspective view in the state where the comb waste taking-in device 18 of the neighborhood was removed.

As shown in FIG. 1, a thread-like supply sliver 3 supplied to the roving machine 1 passes between a plurality of sets of a top roller 4 and a bottom roller 5 in a case 7. The comb waste suction device 2 includes a comb waste intake device 18, a suction port 24, and a comb reciprocating device 10. The comb reciprocating device 10 includes a small motor 11, a cam mechanism 12, a rod 13, a comb reciprocating arm 14, and the like. The rotation of the small motor 11 is converted by the cam mechanism 12 and the rod 13 to make the comb reciprocating arm 14 an endless clearer. The cloth 6 is reciprocated intermittently in the running direction. The comb dust take-in device 18 includes a dust collecting tube 19, a shutter 21, and the like. A comb 8 is fixed below the dust collecting tube 19, and an end of the comb reciprocating arm 14 is connected to an upper side. And the dust collection tube 19
The comb 8 is intermittently reciprocated in the running direction of the endless clearer cloth 6 to scrape off cotton lint.

As shown in FIGS. 2 and 3, a comb dust take-in device 18 is disposed above the endless clearer cloth 6, and includes a set of closed dust collection tubes 19, a plurality of sets of combs 8 and dust collection tubes. The comb 8 is integrally formed with a shutter 21 at one end of the comb 19, and each comb 8 is held by a comb holder 9 and fixed to a lower side of the dust collection tube 19. A comb dust inlet 20 is opened near the blade at the tip of the comb 8 on the lower surface of the dust collecting tube 19, and the comb dust 26 scraped off by the comb 8 is taken into the dust collecting tube 19. A suction port 24 is opened in the case side wall 23 on the side of the endless clearer cloth 6 in order to suck and discharge the comb waste 26 taken in the dust collecting tube 19 by an air current. The shutter 21 is fixed to one end of the dust collection tube 19 on the suction port 24 side, and is provided with a slide guide 2 provided on a side wall 23.
5 and reciprocate intermittently integrally with the dust collecting tube 19 in close contact with the suction port 24, and the suction port 2
A communication port 22 that allows communication between the dust collection tube 4 and the inside of the dust collection tube 19 is opened in the shutter 21. Therefore, the closed dust collection tube 1
9, only the comb waste intake port 20 and the communication port 22 are open.

As shown in FIG. 4, the suction port 2 is fixed to a dust collecting tube 19 by a reciprocating shutter 21 intermittently.
4 is closed or communicates with the inside of the dust collecting tube 19 via the communication port 22, so that the suction port 24 is opened and closed intermittently by the shutter 21. Moreover, the suction port 24 is connected to the communication port 22 only during the period from immediately before the end of the comb scraping stroke to immediately after the start of the retraction of the comb 8 when the comb 8 fixed to the dust collecting tube 19 advances.
The reciprocating position of the communication port 22, that is, the reciprocating position of the shutter 21 is set so that the communication port 22 is opened in communication with the communication port and closed in other states. Further, by sequentially shifting and selecting the opening / closing timing of the suction port 24 by each shutter 21 for each comb waste suction device 2, each comb waste suction device 2
The suction and discharge of the comb waste 26 by the air current are sequentially performed.

The comb dust 26 in the dust collecting tube 19 is
While the shutter 4 is open, the air is sucked from the suction port 24, passes through the suction guide 15, the air pipe 16, and the collecting duct 17, and is sent to the dust collecting unit 18 by the blower 27 driven by the motor 28. On the other hand, while the suction port 24 is closed and the suction is interrupted, the comb waste 26 remains in the dust collection tube 20.

[0011] Since the suction of the comb waste 26 is performed intermittently, and therefore, is selectively performed, the capacity of the blower 27 and therefore the motor 28 does not need to be increased.

The comb reciprocating device 10 is used for selecting suction, and no special device is provided.

FIG. 5 is a perspective view of the endless clearer cloth 6 with the comb waste intake device 18 and the comb reciprocating arm 14 near the comb waste suction device 2 removed.
Shows only one set.

[0014]

[Effect of the invention] By setting a shutter that reciprocates integrally with the comb, the suction port is opened only immediately before the end of the comb scraping process and immediately after the start of the comb retreat, and closed in other states. In addition, by sequentially shifting and selecting the opening and closing timing of each shutter, the capacity of the blower and the capacity of the motor can be reduced, which is economically advantageous.
