BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a loading machine according to the present invention. In this embodiment, the loader is
It comprises a main body 1 and an operation lever 2, both of which are connected via a winding shaft 3. The main body 1 includes a pair of left and right side plates 11 and 12.
A locking shaft 13 is provided at the tip end, and a fixed plate 14 is provided at an intermediate portion, and both side plates 11 and 12 are slightly smaller than the width of the main body side belt 41. While keeping a wide interval, the whole is strong. Support holes are formed in the base end portions of the both side plates 11 and 12, and the winding shaft 3 for winding up the winding belt 42 is rotatably supported therethrough. The operation lever 2 includes a pair of left and right side plates 2.
1 and 22 are connected by an operation rod 23, and a support hole is formed at a base end thereof, and this is loosely fitted to the tightening shaft 3. A roller cam 15 is attached to the main body 1 near the locking shaft 13 so that the main body side belt 41 is locked by the roller cam 15 and the locking shaft 13. It functions as a handle for reciprocating rotation. The winding shaft 3 has an insertion hole 31 formed in a portion located between both side plates 11 and 12, and the winding belt 42 is inserted therethrough and wound up on a winding shaft 51 described later. . A ratchet gear 32 is attached to the winding shaft 3, while the ratchet gear 32 is attached to the operation lever 2.
A drive mechanism 6 for rotating the drive mechanism 32 is attached, and a reverse rotation prevention mechanism 7 is mounted on the main body 1. The drive pawl 61 of the drive mechanism 6 and the reverse stop pawl 71 of the reverse rotation prevention mechanism 7 are connected to a ratchet gear. The ratchet gear 32 is rotated clockwise in the drawing by reciprocatingly rotating the operation lever 2 as shown by the arrow A in a state of being engaged with the gear 32. When the ratchet gear 32 is rotated, the wind-up shaft 3 rotates integrally therewith. If the take-up belt 42 is inserted through the insertion hole 31 of the wind-up shaft 3 beforehand, The winding side belt 42 to be wound is wound around this. When the winding belt 42 wound around the winding shaft 3 is rewound, the winding belt 51 is wound on a winding shaft 51 of the winding mechanism 5 described later.
When winding 42 and feeding it out, the engagement between the driving pawl 61 and the reverse rotation preventing pawl 71 with the ratchet gear 32 is released, and the ratchet gear 32 is freely rotated. In this embodiment, the driving mechanism 6 has a driving claw 61 and a knob 62 attached to the side plate 21 via a connecting pin 63.
The drive pawl 61 can be engaged with or released from the ratchet gear 32 by rotating the 62 forward and backward. The drive pawl 61 has a rectangular shape near the center of rotation, and a leaf spring 64 is pressed against the drive pawl 61. When the drive pawl 61 is engaged with the ratchet gear 32, When released, that state is maintained. The reverse rotation preventing mechanism 7 is a side plate of the main body 1.
A long hole 72 is formed in each of the holes 11 and 12, into which a plate-shaped reverse prevention claw 71 is inserted.
A coil spring 73 is contracted between them, and the tendency of the reverse rotation preventing pawl 71 to move forward toward the ratchet gear 32 is urged. The reverse rotation preventing pawl 71 is formed such that the distance between both ends of the cutting edge is slightly larger than the width of the operating lever 2, while the operating lever has an outer diameter of the ratchet gear 32 in the range of B at the base end of the side plates 21 and 22. And the range of C is formed larger than that, the operation lever 2 is
When bent to a degree or less, the anti-reverse pawl 71 engages with the ratchet gear 32, and when the operating lever 2 is extended to an angle larger than that, the anti-reverse pawl 71 is pushed down by the side plates 21 and 22, and The engagement is released.
In this embodiment, the insertion shaft 31 is exposed by forming two convex-shaped members facing each other at an interval of about 3 to 5 mm. Further, the interval between the two side plates 21 and 22 of the operation lever 2 is set to the both side plates 11 and 12 of the main body 1.
Is slightly wider than twice the thickness of the ratchet gear 32 than the gap between the ratchet gear 32 and the ratchet gear 32 between the side plates 11 and 21;
Although an example is shown between the side plates 12 and 22, this may be provided only between the side plates 11 and 21 or outside the side plate 21.

The take-up mechanism 5 is attached to the operation lever 2 of the buckling machine constructed as described above, and the take-up belt 42 is wound around the take-up mechanism 5. One end of the winding shaft 51 of the winding mechanism 5 protrudes from the side plate 22, and a handle 52 is mounted on the winding shaft 51.
It is designed to rotate 51. The handle 52 is designed so that the handle 53 can be folded 90 degrees as shown by a dotted line in the figure, and a locking projection 54 is protruded from the handle 53. On the other hand, an engagement groove 55 is formed in the side plate 22, and when the handle 52 is turned to a predetermined position and the handle 53 is folded, the locking projection 54 fits into the engagement groove 55 and the handle 52 is locked. It is supposed to be.

[0008] When the packing is to be carried out, first, the handle 53 is set up, the handle 52 is freely rotated, the take-up belt 42 is pulled out by a predetermined length, and the take-up belt 42 is hung on the baggage.
Hooks 43 and 44 attached to the base end of 41 and the base end of take-up belt 42 are hooked on hooks of a truck of a lorry, and then turn handle 52 until take-up belt 42 is not loosened. Roll up. Then, it is confirmed that the drive mechanism 6 and the ratchet gear 32 are in the engaged state, and the operation lever 2 is reciprocated as shown by the arrow A. Then
The take-up belt 42 is wound around the wind-up shaft 3, and the apparent dimensions of the main-body belt 41 and the take-up belt 42 are shortened by that amount, and the load is tightened. To release the closed state, the knob 62 of the drive mechanism 6 is tilted forward,
The engagement of the driving pawl 61 with the ratchet gear 32 is released, and the engagement of the reverse rotation preventing pawl 71 is also released by expanding the operation lever 2 to a certain angle or more, so that the winding belt 42 wound around the winding shaft 3 is released. To bring out. In this embodiment,
The handle 52 is formed separately from the winding shaft 51 (to be rotatable with respect to the winding shaft 51).
When the handle 52 is pressed against the take-up shaft 51 and an appropriate static friction force is generated between the take-up belt 51 and the take-up belt 42 is not loosened and the take-up belt 52 cannot be taken up, the handle 52 is kept at a certain degree or more. The take-up belt 42 can be pulled out from the take-up shaft 51 by applying a certain or more retraction force to the take-up belt 42 even when the handle 52 stops rotating. Therefore, when the loading belt is tightened, when the winding belt 42 is wound up until the slack disappears, that is, when the winding belt 42 is wound up to a state where it cannot be further wound up, the handle 52 Even if it stops at the position of, it is further rotated to the predetermined position,
The handle 52 can be locked by engaging the engagement groove 54 with the engagement groove 55, and when the winding side belt 42 is wound around the winding tightening shaft 3 in this state, the winding shaft 51 idles. Then, the winding belt 42 is pulled out, so that the operation of winding the winding belt 42 around the winding shaft 3 can be performed.

[0009]

As described above in detail, according to the present invention, the main body 1 and the operating lever 2 are connected via the winding shaft 3 to form
The winding mechanism 5 is attached to the operation lever 2 of the packing machine configured to wind the winding belt 42 around the winding belt 42, and the winding belt 42 is wound around the operating lever 2. The side belt 42 is wrapped around, and a necessary amount can be paid out when tightening the load. As a result, conventionally, the packing machine is separate from the packing machine, and each time the packing work is performed, it has to be inserted into a predetermined portion of the packing machine, in this embodiment, the insertion hole of the packing shaft. The take-up belt is integrated with the loader, handling is easier, and there is no need to insert the take-up belt into the specified position of the loader at the time of loading work. Improved. Conventionally, the take-up belt was separate from the loader, so it was necessary to remove the take-up belt from the loader and wind it up each time the load was released. According to the present invention, it is sufficient to wind up only the portion of the winding belt that has been unwound from the loader, so that the workability is significantly improved. or,
The handle of the take-up mechanism can be folded and the handle can be locked. The take-up side belt wound up by the mechanism is not spontaneously fed out.

The handle is separate from the take-up shaft, and is configured to run idle when a predetermined rotational force is applied between the handle and the take-up belt. When the handle is stopped at any position, it can be further rotated to a predetermined position when the handle is stopped, so that the locking projection is engaged with the engagement groove to lock it. There is an advantage that can be. In addition, if the take-up belt wound around the take-up shaft is pulled with a certain force or more while the handle is locked, the force acts as a force to rotate the take-up shaft. The take-up shaft idles by the force, and the take-up side belt is pulled out. Therefore, when carrying out the work of tightening the load, it is possible to wind the winding belt on the winding shaft, lock the handle, and then wind the winding belt on the winding shaft. There is no inconvenience that the take-out belt is unnecessarily extended.
