Abstract

PURPOSE:To smoothly tow bulky sections having, for example, floats attached to a fishing net, by towing a member such as, for example, a fishing net to be towed with the use of upper and lower rollers which are separately driven, and by separating both rollers, with the use a separation control mechanism, in parallel with each other or by being inclined to each other. CONSTITUTION:Rollers (a, b) are separately rotated by motors 9, 19, respectively, while the space between the rollers (a, b) is adjusted in accordance with the size and thickness of a member to be towed, such as, for example, a fishing net, so that the member is towed by the rollers (a, b). Upon towing the member becomes entirely bulky due to the oncoming of, for example, a fishing net float to the position of the rollers (a, b), the rollers (a, b) are subjected to pressing force in the direction in which the rollers (a, b) are separated from each other. The pressing force is transmitted to a slidable pipe 23 through a cylinder tube in a separation control mechanism 18. The slidable pipe 23 slides, overcoming a spring 26, so that the roller (b) is separated and then returns to its original position after the bulky section having passed. Further, when one side alone of the member to be towed becomes bulky due to a float or the like, the roller (b) is inclined to be separated. However, since the roller (b) has wheels 33, at its both ends, engaged to the rail rods of guide rails 1, 2, a shaft and the slidable pipe slide to be extended and inclined.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a towing device in which a pair of rollers are horizontally mounted opposite each other, and both rollers tow a fishing net, etc. It is used to tow fishing nets and other items and load them onto trucks, etc.

In conventional traction devices of this type, both rollers are fixed in fixed positions and rotated, and therefore have 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 both rollers depending on the size of the fishing net, etc., but with conventional equipment, it was not possible to adjust the top gloss.

(2) Fishing nets have floats, sinks, etc., and when these floats, etc. are caught in the area between both rollers, if the gap between both rollers does not open automatically, the floats, etc. will be caught between both rollers. Without it, both rollers will slip (idle), making further traction impossible and putting strain on the fishing net, potentially causing it to break.

(3) While the fishing net is being pulled, it may become bulky and biased to one side (right or left) of the rollers. Ideally, the gap between the rollers on the bulky side would automatically widen depending on the amount, but this measure is not possible with conventional devices.

The present invention &-1 An object of the present invention is to provide a towing device for fishing nets, etc., which can solve the problems of the conventional devices described above.

(Refer to the spear Otsu figure and the off-line figure) The spear 20-ra b is horizontally mounted opposite to the first roller.

Next, the 3-20-lar b is configured to be expandable and retractable in the axial direction, and in the embodiment, it is a spear! As shown in the figure, prime mover 1
9 fixes the output shaft 34 that rotates through a gear to the center of the side plate 35 at one end of the second roller, and at the center of the side plate 36 at the other end of the spear 20 - roller b, the output shaft 34 is fixed to the center of the side plate 36 at the other end of the roller b. A sliding tube 37 of an appropriate length is protruded, and the sliding tube 37 is slidably fitted and supported on a shaft 38 rotatably supported by the support member 14. As a result, the sliding tube 37 and the shaft 38 slide relative to each other (see Figure 7). Therefore, the shaft 20-lar b can be expanded and contracted in the axial direction, and in the same figure, the shaft 39 is The bar receiving plate = 10 provided at the tip of the plate 4 provided at the tip of the sliding tube 37
The spring 39 is interposed between the shaft 38 and the roller b, and the spring 39 presses the shaft 38 and the roller b in the direction of separation, thereby applying a contractile force. 3. In this case, other mechanisms can be used as the means for extending the shaft 20-ler in the axial direction, such as making the metal tube 15 a double tube that is expandable and retractable.

In addition, in the embodiment, guide rails 1 and 2 are installed vertically, and 3 and 2
The kite rails 1 and 2 are arranged horizontally, and the second roller b is moved horizontally. Alternatively, the spear 10 may be moved toward and away from the spear 10 in one direction.

In the diagram, 42 + 43 Oyohi 44 + 45 Ha both rollers a +
The guide rods 46 and 47 erected before and after both ends of b are guide rods installed horizontally below the guide rods 42 and 43 and 44 and 45, respectively. In the figure, parts with the same symbols are the same. It shows the constituent parts.

The present invention has the above-mentioned structure, and its method of use and effects will be explained next. The towing device of the present invention can be used, for example, on a ship when pulling a fishing net from the sea onto a ship;
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 introduced into the cylinder tube 27 from the entrance/exit 29 side of the drawing contact/separation control device 18, 1.8, the cylinder tube 27 slides upward, so both ends are fixed to the cylinder tube 27. The second roller b rises while maintaining parallel to the spear 10-ra and both rollers a+
If b is separated and pressure is introduced from the entrance/exit 30 side,
Since the cylinder tube 27 slides downward, the spear 20-
Ra b approaches spear 10-ra a side. Then, by stopping the pressure introduction (blocking a circuit not shown), the spear 20-lar b is stopped (fixed) at that position.

Therefore, first, operate as above to remove both rollers a and b.
This interval is adjusted according to the size and thickness of the object to be towed.

Then, when both rollers a and b are rotated by prime movers 9 and 19, respectively, and a towed object N such as a fishing net is inserted between both rollers a and b as shown in the spear 2, the fishing net etc. N is rotated by both rollers a, b
Towed by VC. During this towing, parts such as floats attached to the fishing net come to the position of rollers a+b, and the object to be towed is moved to roller a.

When the rollers (1+b) are placed in the position between 6 and 6 and become bulky overall, both rollers (1+b) receive 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 contact and separation control mechanisms 1.8,
The object is transmitted to the sliding tube 23 through the cylinder tube 27 of No. 18, and the sliding tube 23 slides upward against the pressing force of the spring or the like 26, so that the 2-20-lar b receives the object. It separates to the extent that it can be inserted, and after passing, it returns again by the action of a spring or the like. In addition, when only one side of the towed object N such as a fishing net becomes bulky due to a float or the like, only the sliding pipe 23 of the approach/separation control mechanism 18 on the bulky side (left or right) is loaded with a spring or the like. It slides against the pressing force of 26, and only one end of the 3.20-ra b tilts enough to receive the object and separates, but the spear 20-ra b Wheels 33, 3 at both ends
3 is each rail rod 1 (L, lb) of guide rails 1 and 2.
2a and 2b, a distance difference occurs due to the rise in the slope (this distance difference increases in proportion to the degree of slope). Therefore, at this time, the shaft 38 and the sliding tube 37 of the spear 20-lar b slide relative to each other, and therefore, the spear 20-lar increases incline while extending in accordance with the distance difference in the axial direction. However, this allows the distance difference caused by the above-mentioned slope rise. After the object passes, the spear 20-ra returns to its original state.

The present invention is constructed as described above, and the present invention has the following effects.

(1) The spear 10-lar and the spear 20-lar are installed horizontally so that they are rotated by separate prime movers, and the spear 20-lar is movable in one direction along the guide rail of the first roller. Since the second roller is configured to be moved toward and away from the first roller in one direction by the contact/separation control mechanism and can be stopped (fixed) at any position, the 710-r and 3"2
The distance between the roller and the roller can be adjusted to the optimum condition for towing depending on the size and thickness of the object to be towed.

(2) Since the 1-20-r is constantly pressed toward the 10-r by a spring built into the approach/separation control mechanism to apply contraction force, there is a certain amount of force between the two rollers arb during traction. When an object (with a large thickness) is being fed in, the second roller moves away from the object to a tolerable extent and returns after passing, thus without interrupting the traction and without putting any strain on the object. (It can be towed smoothly and well.

(3); Since the d-20-r is configured to be expandable and retractable in the axial direction, during towing, if the towed object becomes bulky and partially biased toward one end between the two rollers,
By widening the gap between both rollers as a whole, 1. Since only one end of the roller can tilt and stretch the object to an acceptable extent and leave the object, it is possible to efficiently pull the object as a whole without reducing the traction force. I can do it.

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