Abstract

PURPOSE:To smoothly tow bulky sections in a fishing net, by towing a member to be towed, such as, for example, a fishing net by cooperation of three rollers which are separately driven, and by separating one of rollers from the others in parallel with or by being inclined to the latter with the use of a separation control mechanism. CONSTITUTION:Motors 7, 19, 26 respectively rotate rollers (a, b, c) with the space between the rollers (b, c) being adjusted in accordance with the size and thickness of a member to be towed, to wind a member to be towed, such as, for example, a fishing net onto the roller (a) and as well to wind the end of the member onto the rollers (b, c) in an S-letter shape, or to insert the end of the member wound around the roller (a) between the rollers (b, c), and then the member is towed by cooperation of the rollers (a, b, c). Upon towing, the rollers (a, b) are subjected to pressing force when a float in the fishing net comes to the position of the rollers (a, b). This pressing force is transmitted to a slidable pipe 33 through a cylinder tube 37 in a separation control mechanism 25, and therefore, the slidable pipe 33 slides, overcoming a spring, to separate the roller (c). Further, when one side alone of the fishing net becomes fulky, the roller (c) is inclined and separated to extend in the axial direction.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a first roller positioned at an appropriate height and rotatably suspended horizontally; A towing device for towing fishing nets, etc., with these three rollers, for example, towing fishing nets, etc. from the sea to a ship. It is used for hauling fishing nets, etc. on board a ship and loading them onto a truck.

This towing device wraps the object to be towed, such as a fishing net, on the spear 10-shi and inserts it between the spear 2 and spear 30-lar, or wraps it around the spear 3.2 and the spear 30-lar in an S shape. Each roller is rotated for traction.

By the way, in the conventional traction device of this type, 3.20
-Rar and spear 30-Rar is configured to be fixed at a fixed position and rotated, so it has the following problems.

(1) For example, fishing nets vary in thickness and size depending on their type, and in order to efficiently tow various fishing nets,
It is necessary to adjust the distance between the two rollers (the second and third rollers) depending on the size of the fishing net, but this adjustment has not been possible with conventional devices.

(2) Fishing nets have floats, sinkers, etc., and when these floats, etc. come to the area between the 3rd, 2nd and 3rd rollers, unless the space between both rollers opens automatically, the floats, etc. Both rollers slip (idle) without getting caught between the rollers.
However, there is a risk that further towing will not be possible and the fishing net will be strained and break.

(3) While being pulled, the fluff may become bulky and biased to one side (right or left) of the roller. ), it would be ideal to automatically widen the gap between the rollers (second and third rollers) only on the bulky side of the fishing net according to the amount of bulky fishing net. It is not possible to perform the above operations with the device.

Further, in the embodiment, the guide rail 10. Established '11,
Although the illustration shows a configuration in which the second roller C is moved up and down to move toward and away from the second roller in one direction, it is possible to arrange the guide rails 10 and 11 horizontally and move the second roller C horizontally. The second roller is moved back and forth to approach and separate in one direction'
It may be configured as follows.

In the figure, 52 and 53 are guide rods erected at both front ends of the first roller α, and 54 and 55 are the second guide rods. Third roller b.

The guide rods 56 and 57 erected at both rear ends of C have the same spacing as the guide rods 52 and 53, and the reinforcing rod 58 installed between the connections 44 and 14 has the same spacing as the reinforcing rods 56 and 57.

When the present invention device is used in the form shown in 7 described later, the regulation plate 6o is used to prevent the towed object from being wound up toward the spear 30-ra C side.
For example, if a float attached to a fishing net etc.
This regulation plate 6 o
When using the device of the present invention in the form shown, it is best to lower it downward or remove it.

In addition, the parts with the same reference numerals in the figures indicate the same constituent parts.

The present invention has the above-mentioned structure, and the method of use and operation thereof will be explained next. The towing device according to the present invention can be used on a ship when, for example, a fishing net is pulled up from the sea onto a ship, and
When loading fishing nets on a ship onto a truck on land, the fishing net is fixedly installed on the truck.

When pressure such as hydraulic pressure is simultaneously introduced into the cylinder tube 37 from the entrance/exit port 39 side of both approach/separation control devices 2b + 25, the cylinder tube 37 slides upward, so that the cylinder tube 37 has both ends fixed to the cylinder tube 37. The roller 90-r C rises parallel to the spear 20-r b, and both rollers b and c are separated. Conversely, when pressure is introduced from the entrance/exit 40 side, the cylinder tube 37 slides downward, so the rollers b and c are separated. 3 roller C approaches the spear 20-roller b side. and,
By stopping the pressure introduction (blocking the circuit not shown), the 3'-30-ra C is stopped (fixed) at that position.
do.

So, Mago, operate as above and use spear 2,3r30-
Set the interval between errors b and c. This interval is adjusted depending on the size, thickness, etc. of the object to be towed. and,
Each roller a, b and C is connected to the prime mover 7, 19, 26
, respectively, to wrap the towed object N such as a fishing net onto the roller α, and to wrap the ends of the object N, such as a fishing net, as shown in the figure. 2.730-ra b.

The end of the towed object N wrapped around the cvcs-shaped 1 or the spear 2 as shown in the figure is 1, 2.
inserted between the third roller brc, each of these rollers a,
This will be driven by the collaborative efforts of b and c. In addition,
In this case, when towing in the form shown in Figure 9, 1
, 1-2. Spear 30-Ra b.

If C is rotated a little faster than the spear 10-ra a, and if it is towed in the form of sai and figure, the spear 2 will be faster than the spear 10-ra a.
0-Ra b, and spear 30-Ra C from spear 20-Ra
It is preferable in terms of efficiency to rotate each of them somewhat earlier. During this towing, parts such as large-diameter floats attached to the fishing net move to positions 72.3-30-ra b, c, so that the towed object N is moved between the two rollers brc. When the entire tension is high in the position, the two-degree spears 30-r (b, c) are subjected to a pressing force in the direction of separation from each other due to the biting of the towed object, and this pressing force is applied to both the contact/separation control mechanisms 6, 25. is transmitted to the sliding tube 33 through the cylinder tube 37, and the sliding tube 33 slides upward against the pressing force of the spring or the like 36.
The roller C moves away to the extent that it can receive the object, and after passing, it returns again by the action of a spring or the like 36. In addition, only one side of the towed object N such as a fishing net may be damaged by a float or the like. spear 3
0 - When the space is bulky at the position between b and c, only the sliding tube 33 of the approaching/separating control mechanism 25 on the bulky side (left or right) resists the pressing force of the spring or the like 36. Sliding spear 30-ra C
In the case of 1,1-30-Lar C, only one end side is tilted to the extent that the object can be received and separated, but in the case of 1,1-30-Lar C, the wheels 43, 43 at both ends are attached to each rail rod of the guide rails 10, 11. Since they move in unison with 1oa, 10b, Lla, and llb, a distance difference occurs due to the rise in the slope (this distance difference becomes a dog in proportion to the degree of slope). Therefore,
At this time, the shaft 48 and the sliding tube 47 of the third roller C slide relative to each other, so that the 730-roller C tilts upward while extending in the axial direction according to the distance difference. This allows the distance difference caused by the above-mentioned slope rise.

After the object passes, the third roller C returns to its original state by the action of a spring or the like 36.

The present invention is configured as described above, and according to the present invention, the following effects can be obtained.

(a) The present invention includes a first roller, a spear 20-ra, and a spear 3.
It is equipped with three 0-roller rollers, and the towed object is towed by the cooperation of these rollers, so that efficient towing can be achieved.

(b) The second roller and the spear 30-r are mounted horizontally so that they are rotated by separate prime movers, and the spear 30-r is movable in one direction along the guide rail. , 1-30-ra to approach/separation control mechanism, 1'2
Since the structure is such that the 0-r can be moved toward and away from the 20-r in one direction and stopped (fixed) at any position, the distance between the 20-r and the 30-r can be adjusted depending on the size and thickness of the towed object. It can be adjusted to the best condition for towing according to your needs.

Since the kii30-lar is constantly pressed toward the spear 20-lar side by a spring built into the contact/separation control mechanism to apply contraction force, there is no possibility that a certain amount of force will be generated between 72.730-larb and 0 during towing. When an object with a thickness of 100 mm thick is being fed in, the roller moves away from the object to an allowable extent and returns after passing, thus not interrupting the traction and applying force to the towed object. It can be towed smoothly and without problems.

), 1-30-Rar C is configured to be expandable and retractable in the axial direction, so that during towing, the towed object is
When a case arises where the object is partially biased toward one end of the rollers and becomes bulky, the distance between both rollers b and c is not widened as a whole, and only one end of the rollers is tilted and extended to an extent that allows the object to be accommodated. Since the vehicle can be separated from the vehicle while moving, it is possible to efficiently tow the vehicle without reducing the overall traction force.

It goes without saying that the towing device of the present invention can be used to tow things other than fishing nets.
