Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an apparatus for producing a continuous fiber yarn bundle. More specifically, continuous fiber yarn bundles (hereinafter simply referred to as tows) are used as raw material fibers for so-called tow spinning, such as parlot spinning and pacific converter spinning, in which synthetic fibers are cut using a cutting machine. This relates to manufacturing equipment.

[Prior Art] Normally, tow such as nylon fiber, polyester fiber, and acrylic fiber is continuously supplied to a tow storage box by a shaking device during the product production stage, and when the amount reaches a predetermined amount, an operator The continuous tow between the shaking-off device and the tow storage box was manually cut, the two tow ends were tied together with string, and the tow was packed. In this case, binding requires good binding force to prevent it from coming off the tow, and good workability for attaching and detaching. However, for example, conventional bundling means such as string knots never have sufficient workability for bundling and attaching and detaching. I couldn't say it.

[Problems to be Solved by the Invention] An object of the present invention is to solve the above-mentioned problems of conventional tow tying tools and tying means, and to facilitate tow end processing by incorporating equipment for tow cutting and tying operations. The goal is to achieve high efficiency and continuous automation with peripheral devices. Another problem is to provide a tow that can be easily attached and detached when binding the ends of the tow.

[Means for Solving the Problems] An object of the present invention is to provide a tow gripper disposed above and below, a tow cutter provided between the tow grippers, and a tow cutter provided on the upstream and/or downstream side of the cutter. and a plate-shaped binding tool provided in the middle of the tow gripper, which has a circular through hole in the center, a notch at the edge, and a cut leading from the bottom of the notch to the circular through hole. The problem can be solved by a tow manufacturing apparatus comprising a binding device attachment means attached to the end of the tow.

Hereinafter, the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a side view showing an example of a tow manufacturing apparatus according to the present invention.

In FIG. 1, there are tow grippers 6 disposed above and below, a tow cutter 8 provided in the middle, and a tow cutter 8 provided upstream and/or downstream of the cutter 8 and in the middle of the tow gripper 6. A binding device 7 is provided.

That is, the tow gripper 6 is moved forward and backward toward the tow 1 by a cylinder (not shown), and serves to move the tow 1 to an arbitrary position. Note that details of the grasping and supporting mechanism will be described later.

The binder 7 is provided at a fixed position and serves to insert the tow 1 into the plate-like binder 5.

As shown in FIG. 7, this plate-shaped binding tool 5 has a plate-like shape with a circular through hole 2 in its center, a V-shaped notch 3 at its edge, and a V-shaped It has a cut 4 communicating from the bottom of the notch 3 to the circular through hole 2. The feature of this binding tool is that the outer periphery of the plate-shaped binding tool is used to guide the tow 1 into the hole 2 of an appropriate size according to the thickness of the tow 1 so as to bind the ends of the tow. It has a cut 4 extending to the side. In order to secure the tow 1 using the plate-shaped binding device 5, it is preferable to insert the tow 1 in a tensioned state into the hole 2 of the plate-shaped binding device 5. The reason for this is that when the tension of the tow is released, the elastic recovery force of the tow 1 itself provides a binding force sufficient to grip the ends of the tow. In addition, the plate-like binding tool 5 has holes 2.
It is preferable to provide a protrusion (not shown) on the periphery. This makes it even more difficult for the binding tool to come off from the tow 1 due to the resistance of the tow 1 and the protrusion. The material of such a plate-shaped binding tool 5 is preferably paper or plastic, and the thickness is preferably 0.5 to 2 mm.
The size is preferably about 60 x 70 mm. Furthermore, if the plate-shaped binding tool 5 is colored in various colors as appropriate, it is effective for distinguishing the types of tow or identifying the head and tail of the tow in the tow storage box. Note that details of the binding mechanism will be described later.

Additionally, the tow cutter 8 is a cylinder (not shown).
The tow 1 is moved forward and backward by the tow 1, and serves to cut the continuous tow 1.

FIG. 2 is a detailed plan view of the tow gripping device 6 shown in FIG.

The tow gripping mechanism is a cylinder 11 and a rod 1.
By pressing 0, the plurality of claws 9, 9' provided vertically at different levels rotate in opposite directions with the base as the center of rotation, trapping the tow 1 within the claws 9, 9'. Such a tow gripper 6 grips the tow 1, thereby facilitating cutting and binding.

FIG. 3 is a detailed plan view of the binding device 7 shown in FIG. It consists of the main parts of the operating cylinder 16.

FIG. 4 is a longitudinal cross-sectional view of the binding device 7 shown in FIG. The figure shows the state of being pushed into the twister 12.

Fig. 5 is an enlarged plan view of the pin portion around the twister in Fig. 3, and Fig. 6 is a side view of Fig. 5, where A, A', B, B', and C each indicate the pin. (However, A' and B' are rotatable pins).

In this binder 7, when the twister operating cylinder 15 (15'; cylinder shaft) is operated, one side of the twister 12 is connected to the pin A and
The tip moves downward using A' as a fulcrum, and the other tip moves upward using pins C, B, and B' as fulcrums. By twisting the pair of twisters 12 in opposite directions in this way, the plate-like binding tool 5 is brought into a state where the cut is wide open and the tow introduction port is opened, as shown in FIG. .

In addition, when inserting the tow 1 into the plate-shaped binding device 5, it is easier to insert it from the gap 〓H (width of the cut 4 before twisting) than from the gap 〓h in FIG. It is desirable to consider the arrangement of the tow 1 and the binder 7 so that the axis of the tow 1 and the center line of the plate-like binder 5 form an appropriate angle to each other.

With the configuration and functions of the device of the present invention described above, the following operations can be automatically performed to bind and cut the tow 1.

(a) Twist the twister 12 to give twist to the plate-shaped binding tool 5.

(b) After the two tow grippers 6 open the claws 9, 9' provided at different levels above and below and move forward, the claws 9,
The tow 1 is gripped by closing 9'.

(c) By returning the two tow grippers 6,
The tow 1 is inserted into the hole 2 of the plate-like binding tool 5.

(d) By returning the twister 12, the twist of the plate 5 is resolved and the binding of the tow 1 at two locations is completed.

(e) The tow cutter 8 advances and returns after cutting the bound tow 1.

(f) When the pusher 14 moves forward after retracting, a new plate-shaped binding tool 5 is pushed into the twister 12, and at the same time, the plate-shaped binding tool 5 that has achieved tow binding is transferred to the new plate-shaped binding tool 5. As a result, it is pushed out from the twister 12.

(g) The tow gripper 6 moves forward, opens the claws 9 and 9', and releases the tow 1.

Note that it is desirable that the two tow grippers 6 on the upstream and downstream sides of the tow cutter 8 shown in FIG. 1 reciprocate a predetermined distance while maintaining an appropriate forward inclination between them. That is, due to this movement, the two tow grippers 6 move forward and return to grip the tow 1, thereby stretching the tow 1 to be bound and cut by the necessary amount and applying a constant tension, so that the tow 1 to be bound and cut is This is because it becomes easier.

[Effect of the invention] The present invention has the following excellent effects.

(1) The automation of conventional tow cutting and tying processes was delayed, but by using the present invention, peripheral processes that are already well-equipped can be made continuous, and this can be applied to a wide range of tow manufacturing processes. Extensive automation can be achieved. This greatly improves tow productivity. Furthermore, since the device structure is simple, there are fewer breakdowns and maintenance is easy.

(2) By using the device of the present invention, tow binding work can be substantially automated. Therefore, operators who have been engaged in this type of work can now engage in more advanced and efficient work.

(3) In the tow obtained by the device of the present invention, the plate-shaped binding tool can be easily attached and detached, and the work efficiency is improved.
