(First embodiment)
1. Configuration of a Clamping Machine FIG. 1 is an external front view of a cargo clamping machine 1 according to the present embodiment. FIG. 2 is a side view of the loading machine 1. The load clamping machine 1 uses a belt-like belt 3 to fasten and fix a load placed on a carriage. The belt 3 is an example of a winding object having flexibility. A load hook 3 </ b> A is provided at the tip of the belt 3.

  As shown in FIG. 3, a winding drum 7, a locking hook 8, and the like are provided on the main body portion 5 of the cargo clamping machine 1. The main body 5 includes a frame 5A, a cover 5B, and the like. The frame 5 </ b> A is a rigid body provided with a winding drum 7 and a locking hook 8.

  The frame 5A according to the present embodiment is configured by a metal plate such as SPCC. The locking hook 8 is a locking portion for hooking (locking) the main body portion 5 (loading machine 1) to the locked object.

  In the present embodiment, as will be described later, the back plate portion of the carriage is assumed as an object to be locked. A back board part is a site | part which controls that the mounted load moves to a horizontal direction. The locking hook 8 according to the present embodiment is integrally formed with the frame 5A by plastic processing such as press processing.

  The winding drum 7 is a cylindrical or columnar (in this embodiment, cylindrical) rotating body that winds the belt 3. The spring 7 </ b> A is an elastic body that applies an elastic force (hereinafter referred to as a winding force) in a direction to wind the belt 3 to the winding drum 7.

  The spring 7A according to the present embodiment is a leaf spring (spring spring) wound in a spiral shape. The spring 7 </ b> A is housed in a flange portion (saddle portion) 7 </ b> C provided at the other end in the rotation axis direction of the winding drum 7.

  The flange portion 7 </ b> C is integrated with the winding drum 7. One end side (the center side of the spiral) of the spring 7A is locked and fixed to the rotating shaft 7B. The other end side (the outer side of the spiral) of the spring 7A is locked and fixed to the flange portion 7C. For this reason, the elastic force of the spring 7A is transmitted to the winding drum 7 through the flange portion 7C.

  Even if the spring 7A is (a) the amount of elastic deformation increases with an increase in the pull-out length of the belt 3, and (b) the entire belt 3 is wound around the winding drum 7, A pre-set winding force is generated. For this reason, the winding drum 7 always receives the winding force from the spring 7 </ b> A regardless of the drawing length of the belt 3.

  The rotating shaft 7B of the winding drum 7 is fixed to the frame 5A by caulking, welding, screwing or the like. A ratchet gear 9A is provided on one end side in the rotational axis direction of the winding drum 7 (in this embodiment, on the frame 5A side).

  The ratchet gear 9A rotates integrally with the winding drum 7. The ratchet gear 9A according to this embodiment is integrated with one end of the winding drum 7 in the rotation axis direction. The ratchet gear 9 </ b> A according to the present embodiment is larger than the outer dimension of the winding drum 7 and also serves as a flange portion (saddle portion) of the winding drum 7.

  As shown in FIG. 4, the ratchet gear 9A constitutes a ratchet mechanism 9 together with the pawl members 9B and the like. The ratchet mechanism 9 restricts the winding drum 7 from rotating in the direction in which the belt 3 is pulled out (hereinafter referred to as the pulling direction) and the direction in which the belt 3 is wound up (hereinafter referred to as the winding direction). ) Has a function of allowing the winding drum 7 to rotate.

  That is, in the state where the pawl member 9B is engaged (engaged) with the ratchet gear 9A, when the force that rotates the take-up drum 7 in the pulling direction acts on the take-up drum 7, the pawl member 9B is moved to the ratchet gear 9A. Therefore, the rotation of the winding drum 7 is restricted.

  In the state where the pawl member 9B is engaged with the ratchet gear 9A, when the force that rotates the winding drum 7 in the winding direction acts on the winding drum 7, the pawl member 9B slides in contact with the ratchet gear 9A and rotates. Therefore, the winding drum 7 is allowed to rotate.

  The pawl member 9B is pressed toward the ratchet gear 9A by a spring (not shown). The lock lever 9C is an operation unit that is operated by a user, and is an operation unit for switching between a locked state and an unlocked state.

  The locked state refers to a state in which the pawl member 9B can be engaged with the ratchet gear 9A. The non-locked state refers to a state in which the pawl member 9B cannot be engaged with the ratchet gear 9A. That is, the function of the ratchet mechanism 9 described above is exhibited when the lock lever 9C is in the locked state. When the lock lever 9C is in the unlocked state, the function is not exhibited.

  In the present embodiment, as shown in FIG. 1, in addition to the lock lever 9C, a safety lock lever 9D serving as a second operation portion is provided. The safety lock lever 9D is an operation unit for holding the pawl member 9B in a state where the ratchet gear 9A and the pawl member 9B are engaged (hereinafter also referred to as an engagement lock state).

  The rotation axis Lo of the winding drum 7 is orthogonal to the plate surface of the frame 5A as shown in FIG. That is, the width direction W of the belt 3 wound around the winding drum 7 is parallel to the rotation axis direction Lo.

  As shown in FIG. 4, the width direction W of the belt 3 drawn out from the winding drum 7 (main body portion 5) is orthogonal to the rotation axis direction Lo. For this reason, in this embodiment, it has the turning roller 11A which twists the belt 3 introduced into the main body 5 and guides it to the winding drum 7 by approximately 90 degrees.

  As shown in FIG. 3, the turning roller 11A is a conical rotating body having a rotation axis L1 parallel to the rotation axis Lo. A guide roller 11B that guides the belt 3 to the take-up drum 7 in cooperation with the turning roller 11A is provided on the downstream side in the pulling direction from the turning roller 11A (the upper side in FIG. 3).

  The rotation axis L2 of the guide roller 11B is orthogonal to the rotation axis Lo as shown in FIG. That is, the belt 3 is twisted approximately 90 degrees by the turning roller 11A and the guide roller 11B.

  The mounting tool 13 shown in FIG. 4 is a member that allows the main body 5, that is, the load-clamping machine 1, to be mounted on an object to be locked (in this embodiment, the back plate of the carriage). In this embodiment, since the back plate portion is an iron-based metal, the mounting tool 13 is composed of a permanent magnet.

  The winding operation unit 15 illustrated in FIG. 4 is a handle unit that is rotated by a user. The user can rotate the winding drum 7 in the winding direction by rotating the winding operation unit 15 in the locked state. In addition, since it is in a locked state, the winding drum 7 cannot be rotated in the pulling direction.

  The winding operation unit 15 is an operation unit that can rotate around a rotation axis parallel to the rotation axis Lo of the winding drum 7. The winding operation unit 15 according to this embodiment is configured to directly rotate a flange portion (saddle portion) 7 </ b> C provided at the other end in the rotation axis direction of the winding drum 7. And the winding operation part 15 serves also as the cover which covers the spring 7A accommodated in the flange part 7C.

2. Method for Using the Clamping Machine FIG. 5 is a diagram showing a state before the start of the capping operation. The cart 30 includes a mounting table 31, a back plate portion 32, a handle 33, and the like. The mounting table 31 is a plate-shaped table on which luggage can be mounted. Wheels (not shown) such as casters are provided on the lower surface of the mounting table 31 in the vertical direction.

  The handle 33 is a part gripped by the user. The force that the user acts on the cart 30 is input to the cart 30 via the handle 33. The handle 33 includes a pair of column portions 31A protruding in the vertical direction from the mounting table 31, a grip portion 31B extending in the horizontal direction by connecting the upper ends of the pair of column portions 31A, and the like.

  The back plate portion 32 is a band plate-like member that restricts the load placed on the placement table 31 from moving in the horizontal direction (the handle 33 side). The back plate portion 32 extends in the horizontal direction between the pair of column portions 31A and is connected to the column portions 31A at a portion on the lower side in the vertical direction than the grip portion 31B. The back plate portion 32 is an iron-based metal such as SPCC.

  First, as shown in FIG. 5, the user mounts the load clamping machine 1 on the back plate portion 32 using the mounting tool 13. At this time, the posture of the cargo tightening machine 1 needs to be a posture in which the locking hook 8 can be locked to the lower end side of the back plate portion 32.

  Next, the user operates the safety lock lever 9D to release the engaged state, and then operates the lock lever 9C to make it unlocked. In this state, the user pulls out the belt 3 (see FIG. 6) so as to fasten the load with the belt 3 (see FIG. 6), and hooks the loading hook 3A of the belt 3 on the carriage 30 (see FIGS. 7 and 7). 8). Thereafter, the user operates the lock lever 9C to bring it into a locked state.

  As a result, the elastic force of the spring 7A increases and the winding tension generated in the belt 3 increases, and the locking hook 8 opposes the tension acting on the belt 3 by being hooked on the lower end of the back plate portion 32. Then, the main body 5 (loader 1) is locked to the back plate 32.

  At this time, since the tension generated in the belt 3 is a winding force due to the elastic force of the spring 7A, there is a case where the tension is insufficient and a sufficient closing force cannot be obtained. When such a packing force is insufficient, the user can increase the packing force (tension) by rotating the winding operation unit 15 and winding the belt 3 (see FIG. 9). .

  The user operates the safety lock lever 9D after the hook 3A of the belt 3 is hooked on the carriage 30, or the winding operation portion 15 is rotated to increase the tightening force, and the pawl member is operated by operating the safety lock lever 9D. The carriage 30 is moved with 9B engaged.

  In addition, in order to cancel the cargo tightening state, the user operates the safety lock lever 9D to release the engaged state, and then operates the lock lever 9C to make it unlocked. Thereby, the drawn-out belt 3 is wound around the winding drum 7 by the elastic force of the spring 7A.

3. Characteristics of the Clamping Machine According to the Present Embodiment Since the cargo clamping machine 1 according to the present embodiment includes the mounting tool 13, the cargo clamping machine 1 can be easily mounted on the back plate portion 32. When the load tightening operation proceeds and tension is generated in the back plate portion 32, the locking hook 8 locks the load clamping machine 1 to the back plate portion 32 against the tension.

  For this reason, the mounting tool 13 does not need to exhibit the mounting force which can oppose the said tension | tensile_strength. That is, it is sufficient for the mounting tool 13 to exhibit a mounting force that does not drop the back clamp 32 due to its own weight. Therefore, the configuration of the wearing tool 13 can be simplified.

  As described above, the load clamping machine 1 according to this embodiment does not increase the mounting force exerted by the mounting tool 13, and the load clamping machine 1 is connected to the back plate portion via the locking hook 8 simultaneously with the load clamping operation. Since it can be firmly connected to 32, it is possible to easily complete the closing operation.

  Since the mounting tool 13 has a configuration using permanent magnets, the cargo tightening machine 1 can be easily attached to and detached from the carriage 30. Therefore, since the same cargo tightening machine 1 can be easily used by the plurality of carriages 30, the cargo tightening operation can be easily completed.

  In addition, the clamping machine of patent document 1 is fixing the said clamping machine to the back surface side of a mounting base via mechanical fasteners, such as a screw, and an exclusive attachment member. For this reason, it is difficult to easily attach and detach the loading machine described in Patent Document 1 to the carriage.

Since the winding operation unit 15 according to the present embodiment can rotate around a rotation axis parallel to the rotation axis Lo of the winding drum 7, the operability of the winding operation unit 15 can be improved.
That is, when the winding operation unit 15 is configured to rotate around a rotation axis parallel to the rotation axis Lo of the winding drum 7, the winding operation unit 15 is placed on the user side, that is, the front surface with respect to the loader 1. Can be located on the side. Therefore, the operability of the winding operation unit 15 can be improved.
