Description

TECHNICAL FIELD The present invention relates to a device for feeding a linear body such as a small-diameter corrugated pipe in its axial direction, and more particularly to a device for sandwiching an endless belt to give a feeding force. is there.

Conventional technology For example, when cutting a small-diameter corrugated tube wound into a certain size into a heat pipe container, the corrugated tube fed from the drum is passed through a straightening roller to remove curl and straighten it. In addition, the feeding device for feeding the corrugated tube needs to be arranged between the straightening roller and the cutter. Further, since the feeding device applies a feeding force to the corrugated tube which has already been straightened, the corrugated tube is not curved, and therefore, conventionally, the linear strip like the above corrugated tube is used. As a feeding device for the body,
An endless belt such as a rubber belt was used to give a feeding force to the filament. Ie 1
A pair of endless belts are located across the linear body, and one of the endless belts is driven by a motor, and the other endless belt is used to hold the linear body in order to increase the frictional force with the linear body. The structure of attaching is common.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-mentioned conventional device, one endless belt of the endless belts sandwiching the linear body is driven to give a feeding force to the linear body, and the other endless belt is Since only a pressing force is generated to prevent slippage, the driving force for the filamentous body is not always sufficient, which causes the following problems. That is, when the one endless belt is driven to drive the linear body, a driving force can be applied to the linear body even if slippage occurs between the endless belt and the linear body. , It is possible to feed the linear condition in the axial direction, but if the feeding is stopped to cut the linear body, it is against the tension acting on the linear body due to the provision of the straightening roller. Only one of the endless belts receives the force to keep the linear body in a stopped state, and the only part of the endless belt that is positively brought into pressure contact with the linear body is the portion wound around the pulley. As a result, there is a problem that the linear body slides with respect to the endless belt, and the brake of the motor slips, and the linear body is pulled back.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a feeding device capable of reliably maintaining the stopped state of the filamentous body.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides an endless belt having teeth formed at regular intervals on its inner peripheral surface on both sides of a linear member, respectively, as a drive pulley and a driven pulley. And one of them is connected to the motor and each of the drive pulleys is connected to each other by a gear, and between the drive pulley and the driven pulley inside each endless belt, the endless belt A pressing mechanism that arranges a chain that runs in a state of contacting the inner surface of the endless belt and meshes with the teeth of the endless belt around the outer periphery of a block having an almost oval shape, and presses at least one of the blocks toward the filament body side. Is provided.

In this invention, when the drive pulley around which one of the endless belts positioned with the linear body sandwiched is wound, the drive pulley of the other endless belt rotates via the gear. It will be driven and thus both endless belts will be driven.
These endless belts are pressed against the linear body by chains and blocks between the pulleys. Therefore, since the feeding force can be applied to the linear body from both endless belts, a large driving force can be obtained, which is the same when the drive pulley is stopped. As a result, a force for maintaining the striatum in a stopped state is generated, so that the striatum is reliably stopped and is not pulled back.

Here, in the device of the present invention, a chain wound around an oval block is used as a means for pressurizing the endless belt from the inside, so that the endless belt is totally pressed over a wide range. The pressing force is applied to the linear body sandwiched between the endless belts over a wide range, and a large stopping force is applied to the linear body when the feed drive is stopped.
Furthermore, since the chain meshes with the teeth at regular intervals on the inner surface of the endless belt, slippage does not occur between the endless belt and the chain, and this also maintains the stopped state of the filament when the feed drive is stopped. Contribute to.

Embodiment Next, an embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 to 4 are views showing an embodiment of the present invention, and the arrangement of the entire equipment is, as shown in FIG. 4, a drum holding a drum 2 around which a corrugated tube 1 of interest is wound. A vertical straightening roller 4 and a horizontal straightening roller 5 are sequentially arranged in front of the stand 3, and a feeding device 6 is provided following the vertical straightening roller 4 and the horizontal straightening roller 5. Further, a cutting position detecting device 7 and a cutter 8 are arranged in front of the feeding device 6, and the feed of the corrugated tube 1 is stopped and the cutter 8 is stopped by an output signal from a tip position detector 9 arranged further in front of them.
Is driven to cut the corrugated tube 1 into a predetermined length. In FIG. 4, reference numeral 10 denotes a deceleration detector that outputs a signal for reducing the feed rate of the corrugated pipe 1, and reference numeral 11
Is a guide roller for sending out the corrugated tube 1 after cutting.

The construction of the feeding device 6 according to the present invention is as shown in FIGS. 1 to 3, and endless rubber belts 12a, 12b are arranged on both upper and lower sides of the corrugated tube 1 and these rubber belts 12a, 12b are disposed. The corrugated pipe 1 is wound around the drive pulleys 13a and 13b and the driven pulleys 14a and 14b, respectively.
It is designed to run parallel to. Rubber belts 12a, 12
b has a sufficient thickness, and slits are formed at regular intervals on the outer surface in order to ensure good curvature with respect to the thickness, and teeth 15a, 15b at regular intervals are formed on the inner peripheral surface. There is. The pulleys 13a, 13b, 14a and 14b are bearings 16
Gears 18a and 18b meshing with each other are attached to the side surfaces of the drive pulleys 13a and 13b, respectively, so that the drive pulleys 13a and 13b are connected to each other. Further, the lower drive pulley 13b of these drive pulleys 13a and 13b is a speed reducer.
It is connected to the motor 20 with a brake via 19 and is therefore configured to give a driving force to the upper and lower drive pulleys 13a, 13b.

Inside the upper and lower rubber belts 12a, 12b, substantially oval metal blocks 21a, 21b are arranged, and the teeth 1
Roller chains 22a, 22b having the same pitch as 5a, 15b are wound around the outer circumferences of the blocks 21a, 21b, and these roller chains 22a, 22b contact the tight side of the rubber belts 12a, 12b, that is, the corrugated tube 1. The inner surface of the part meshes with the teeth 15a, 15b. The upper block 21a
Is movable up and down, and this block 21a is connected to a slider 25 which is vertically moved by a screw shaft 24 along a guide 23 having a U-shaped cross section. Therefore, by rotating the screw shaft 24, the slider 24 is pushed down. The rubber belt 12a is pressed against the corrugated tube 1. That is, the slider 25, the screw shaft 24, and the guide 23 form a pressing mechanism.

Next, the operation of the feeding device 6 will be explained. First, the screw shaft 24 is tightened and the upper block 21a is pushed down so that the upper and lower rubber belts 12a and 12b firmly clamp the corrugated tube 1 to some extent. When the motor 20 is started, the rotational force is transmitted to the lower drive pulley 13b via the speed reducer 19, and at the same time, the rotational force is also transmitted to the upper drive pulley 13a via the gears 18a and 18b. Is fed forward by receiving the feeding force from the upper and lower rubber belts 12a and 12b. In that case, the feeding force applied to the corrugated tube 1 is greatly influenced by the frictional force generated between the corrugated tube 1 and the rubber belts 12a and 12b.
Is not only each pulley 13a, 13b, 14a, 14b but also the chain 22a, 22b
Is pressed against the corrugated tube 1 by the chain 22a, 22b is wound around the blocks 21a, 21b and exerts a pressing force on the rubber belts 12a, 12b over a predetermined length. Become big enough. Therefore, for example, when the tip of the corrugated tube 1 reaches the position of the tip position detector 9 and the motor 20 is stopped, the upper and lower rubber belts 12a and 12b are positively stopped by the motor 20, so that the corrugated tube 1 is not provided. The corrugated tube 1 can be reliably stopped even if the braking force acts from the upper and lower rubber belts 12a and 12b, and as a result, the pullback force is generated by the straightening rollers 4 and 5 at the preceding stage. Further, since the chains 22a and 22b mesh with the teeth 15a and 15b formed on the inner surfaces of the rubber belts 12a and 12b, the endless belt 1
No slippage occurs between the chains 2a, 12b and the chains 22a, 22b, and this also works effectively for reliably stopping the corrugated tube 1 against the pullback force when the feed drive is stopped.

In the above embodiment, the case of sending a corrugated tube has been described as an example, but the present invention is not limited to the above embodiment, and is also applied to the case of sending a filament other than a corrugated tube. be able to. Further, the belts may be arranged on the left and right instead of being arranged on the upper and lower sides of the linear body.

Effects of the Invention As described above, according to the device of the present invention, the driving force and the stopping force are applied to the endless belts on both sides of the linear body, and the pressing of the endless belt against the linear body is blocked. Since the chain wound around the chain extends the range of transmission of the driving force and the stopping force, the device of the present invention ensures the transmission of the force between the endless belt and the linear body without slippage. Not only is it possible to apply a large feed force to the linear body for that purpose, but as mentioned above, there is no slip between the endless belt and the linear body, and the teeth and chain of the endless belt are The fact that there is no slippage between the endless belt and the chain due to the fact that the and are meshed together makes it possible to reliably hold the filamentous body in a stopped state. .
