Belt Tension Control Apparatus for Article Fixing Belt of Palette and Improved Article Fixing Belt of Palette for Protecting Article

The present invention is a belt tension control device for fixing a load for a pallet that fixes the load with a certain tension according to the type of the load to protect the load that is loaded and fixed on the pallet, and prevents the load from collapsing and falling when the pallet is transported. The present invention relates to an improved pallet fixing device for protecting the load to prevent damage to the load by adjusting the fixing force of the load according to the type of the load and fixing the load to the pallet.

In general, the pallet is for easy transport by loading the load.

Various forms are used to fix the load on the pallet after loading the load on the pallet.

As an example for fixing the load to the pallet, the method of fixing the load to the pallet using a tape is most commonly used.

However, the method of fixing the pallet to the pallet using a tape has a problem in that the fixing force is weak, and the tape cannot be recycled, resulting in a waste disposal cost and a waste of resources.

Another example for fixing the load to the pallet is a method of fixing the belt sling to the pallet using a belt sling.

As an example of a method for fixing a load to a pallet using a belt sling, it has been disclosed in Japanese Patent Application Laid-Open No. 2007-106442 (2007.04.26.), and is shown in FIGS. 1 to 4.

In the above method, one end (6a, 7a) of the belt (6, 7) is passed through the fixing holes (23a, 23b) (see Fig. 2) formed on one side of the pallet body (2), and one end (6a, 7a) of the belt 7a) is fixed by the first fixing means 30 (see Figs. 3 and 4), and the belt surrounds both sides and upper portions of the load 8, and the other ends (6b, 7b) of the belt are the pallet body. As shown in Fig. 1, the load 8 is fixed to the pallet body 2 by the belts 6 and 7 by being fixed by a locking member (second fixing means) 4a, 4b provided on the other side of (2). It is being fixed.

In the above method, in order to fix one end (6a, 7a) of the belt to the pallet, one end (6a, 7a) of the belt is passed through the fixing holes (23a, 23b) formed on one side of the pallet, and shown in FIG. To be fixed by the illustrated first fixing means 30, as shown in Fig. 3, one side end of the belt by passing through the holes 41a, 41b, 51a, 51b formed in the first fixing means 30 in a zigzag (6a, 7a) is fixed.

In this way, in order to fix one end portion (6a, 7a) of the belt (6, 7) to the pallet, it is not easy to fix it by passing it through the first fixing means (30) in a zigzag, so the load is fixed to the pallet. There is a disadvantage that it takes a lot of time to do the work.

Another example of a method for fixing a load to a pallet using a belt sling has been disclosed in Japanese Unexamined Patent Application Publication No. 2001-143970 (2011.07.28.).

In the above method, one end of the belt 4 is inserted into and passed through the fork insertion opening 21 formed through the pallet 2 in order to insert a fork such as a forklift, and the other side of the belt 4 is By surrounding both sides and the upper part of the belt and fixing both ends of the belt with buckles 16, the load 3 is fixed to the pallet 2 as shown in FIG. 5.

In this method, the belt 4 must be passed through the fork insertion port 21 formed on the pallet 2 in order to fix the load on the pallet. To this end, as shown in FIG. 6, a rod having a belt insertion hole must be used in order to insert and fix the end portion of the belt 4.

In order to allow the belt to pass through the fork insertion port 21, the end of the belt 4 is inserted into the belt insertion hole formed on the stick as if threading a needle, and the stick is inserted from one side of the fork insertion port 21. Insert until the end of the stick comes out to the other side of the fork insertion port 21 on the opposite side. Then, check whether the end portion of the belt 4 passes through the fork insertion port 21 by moving to the opposite side, and after separating the end portion of the belt 4 from the belt insertion hole of the bar, the rod is removed from the fork insertion port 21. After carrying out the pulling out operation, the load is fixed to the pallet with a belt (4).

As described above, the method requires not only a tool such as a long stick having a belt insertion hole, but also fixing the end portion of the belt to the stick, inserting the stick into the fork insertion port 21 and passing it through. There is a disadvantage in that the working time required to fix the load to the pallet is lengthened because the operation of moving to the other side and checking, separating the end portion of the passed belt from the rod, and removing the rod from the fork insertion port 21 are performed. .

In order to improve these shortcomings, Korean Patent No. 10-2106324 filed and registered by the present applicant (name of the invention: a load fixing device for a pallet for protecting a load) has been disclosed, which is shown in FIGS. 7 to 10 .

In addition, as shown in FIG. 10, it is possible to protect the upper part of the load by providing a cover part 210 covering the upper part of the load.

The load fixing device for pallets for protecting the loads does not require a tool such as a long stick, but simply pulls the second belt body 230 in a temporarily fixed state by inserting the fixture 250 into the through hole 115. As shown in Fig. 9, since the fixing tool 250 is fixed to the through hole 115 of the pallet 110, the second belt body 230 is fixed to the pallet 110, so that the fixing operation is very simple.

However, the other end portion located under the first belt body 220 and one end portion located at the upper portion of the second belt body 230 are fixed to each other with a buckle 240. Adjust the length of both belts to secure the load to the pallet. As described above, the first belt body 220 and the second belt body 230 are fixed only by adjusting the length of the belt body 230 by the buckle 240. If the length of both belt bodies is too long and the belt body is fixed with the buckle 240 When the tension of the belt body is too small, the fixing force of the load becomes small. If the length of both belt bodies is too short, the tension of the belt body becomes too small and the fixing force of the load becomes too high.

In addition, although it is necessary to adjust the fixing force of the load by the buckle 240 according to the type of the load (the degree of rigidity), mention of the load fixing force of the buckle 240 used in the pallet load fixing device for protecting the load. There is no this at all.

In particular, if the fixing force of the load is too high and the rigidity of the load is low, there is a problem in that the load is crushed by the tension by the belt, but there is no alternative to fixing the load to solve this problem. And it is dependent on the experience of the worker.

Accordingly, there is a need to develop a load fixing device for a pallet for protecting the load to be fixed by adjusting the fixing force of the load (ie, the tension of the belt) according to the type of the load.

The present invention has been conceived to solve the above problems, and an object of the present invention is to fix the load to the pallet by simply fixing the end portion of the belt to the pallet without passing through the fork insertion hole formed on the pallet. It is possible to provide an improved pallet fixing device for the load protection for the load to be fixed by adjusting the fixing force of the load according to the type of the load.

The ratchet gear rotation preventing part rising spring 516 provides an elastic force for the ratchet gear rotation preventing part 515 to rise, and it may be a compression spring that is pressed under the ratchet gear rotation preventing part 515. And, one end is fixed to the ratchet gear rotation preventing unit 515, the other end is fixed to any one of the first left and right side (511, 512), the ratchet gear rotation limiting unit 535 by a torsion force It may be in the form of a torsion spring that provides a rising elastic force.

The first belt body winding rotation shaft 518 is rotatably coupled by connecting the first left and right side portions 511 and 512 to the upper ends of the first left and right side portions 511 and 512 to each other, and the first The other side of the first belt body 420 inserted into the first belt body insertion part 517 is provided with a first belt body insertion part 517 into which the other end of the belt body 420 is inserted. It serves to wrap the ends.

The ratchet gear 520 is positioned outside the first left and right side portions 511 and 512 of the belt fixing portion 510, respectively, and is fixed to both ends of the rotating shaft 518 for winding the first belt body, and the first belt body It rotates in conjunction with the winding rotation shaft 518 and consists of a pair. The teeth of the ratchet gear 520 are generally made in the shape of a triangular tooth, and due to the characteristics of the ratchet gear, rotation is possible in one direction, and rotation is prevented by being caught by the teeth when rotating in the other direction.

The movable part 530 is a first connecting the second left and right side portions 531 and 532 which are respectively located on the outside of the ratchet gear 520 and installed in parallel to face each other, and the second left and right side portions 531 and 532 with each other. It consists of 2 connection parts 533. The movable part 530 is installed to face each other with the belt fixing part 510 around the second belt body fixing shaft 514.

The first belt body winding rotation shaft coupling portion 534 is provided on the upper ends of the second left and right side portions 531 and 532 and the first belt body winding rotation shaft 518 is rotatably coupled.

The ratchet gear rotation limiting portion 535 is fixed to the second left and right side portions 531 and 532 which are lower portions of the ratchet gear 520 so as to move up and down. The ratchet gear rotation limiting part 535 is configured to rotate in one direction along the ratchet gear 520 in contact with the ratchet gear 520 due to the rising, and when the ratchet gear 520 rotates in the other direction When the tension between the first belt body 420 and the second belt body 430 becomes less than a certain size, the ratchet gear 520 is caught and rotates the ratchet gear 520, and the first belt body ( When the tension between the 420 and the second belt body 430 exceeds a predetermined size, it serves to limit the rotation of the ratchet gear 520 to be prevented. In other words, when the ratchet gear rotation limiting part 535 is rotated in one direction (rotating the movable part 530 from the state of FIG. 13 to the state of FIG. 12), it is possible to rotate along the teeth of the ratchet gear 520 Is done. On the contrary, when the ratchet gear rotation limiting part 535 is rotated in another direction (rotating the movable part 530 from the state of FIG. 12 to the state of FIG. 13), it is rotated by meshing with the teeth of the ratchet gear 520. , When the tension between the first belt body 420 and the second belt body 430 is less than a certain size, the upper end of the ratchet gear rotation limiting part 535 is caught by the teeth of the ratchet gear 520. The ratchet gear 520 rotates while rotating together. On the other hand, when the tension between the first belt body 420 and the second belt body 430 exceeds a certain amount, the upper end of the ratchet gear rotation limiting part 535 is the tooth difference of the ratchet gear 520 However, since the tension between the first belt body 420 and the second belt body 430 is large, the ratchet gear rotation limiting unit 535 cannot rotate the ratchet gear 520 and the Only the ratchet gear rotation limiting part 535 is rotated in the other direction (that is, when the ratchet gear 520 is rotated from the state of FIG. 12 to the state of FIG. 13, the ratchet gear rotation limiting part 535 is not rotated. ) Only goes in vain.)

As a result, the ratchet gear rotation limiting unit 535 rotates the ratchet gear 520 only when the tension between the first belt body 420 and the second belt body 430 is less than a certain size. It is limited.

The ratchet gear rotation limiting part rising spring 536 is tangential to the ratchet gear rotation limiting part 535 so that the ratchet gear rotation limiting part 535 is raised to come into contact with the ratchet gear 520, and the ratchet gear The rotation limiting unit 535 provides an elastic force to be raised. The ratchet gear rotation limiting portion rising spring 536 is tangential to the lower portion of the ratchet gear rotation limiting portion 535.

The ratchet gear rotation limiting part rising spring 536 provides an elastic force for the ratchet gear rotation limiting part 535 to rise, and may be a compression spring that is energized under the ratchet gear rotation limiting part 535 In addition, one end is fixed to the ratchet gear rotation limiting part 535, and the other end is fixed to any one of the second left and right side parts 531 and 532, so that the ratchet gear rotation limiting part 535 is It may be in the form of a torsion spring that provides a rising elastic force.

When the ratchet gear rotation limiting part rising spring 536 provides an elastic force for the ratchet gear rotation limiting part 535 to rise, the ratchet gear rotation limiting part 535 is in constant contact with the ratchet gear 520. When the ratchet gear 520 rotates in the other direction, the ratchet gear 520 is caught on the teeth and rotation is prevented.

In the state of FIG. 12, when the tension between the first belt body 420 and the second belt body 430 is less than or equal to a predetermined size, the ratchet gear rotation limiting unit is rotated in the counterclockwise direction. The ratchet gear rotation limiting portion 535 rotates the ratchet gear 520 in a counterclockwise direction, and the first belt body 420 is in a state where 535 is caught by the teeth of the ratchet gear 520. Is wound around the first belt body winding rotation shaft 518.

When the first belt body 420 is wound on the rotation shaft 518 for winding the first belt body, the tension between the first belt body 420 and the second belt body 430 increases, This state is the state of FIG. 13.

If left as it is in the state of FIG. 13, the ratchet gear 520 is rotated in a clockwise direction due to the tension between the first belt body 420 and the second belt body 430. The ratchet gear 520 When the ratchet gear rotation preventing part 515 is caught on the gear, the ratchet gear 520 is prevented from rotating in a clockwise direction.

In this state, when the movable part 530 is rotated clockwise to increase the tension between the first belt body 420 and the second belt body 430, the ratchet gear rotation limiting part 535 It is possible to rotate along the teeth of the ratchet gear 520. When the movable part 530 is rotated clockwise, the state of FIG. 12 is obtained. As described above, the present invention provides the ratchet gear rotation limiting unit 535 only when the tension between the first belt body 420 and the second belt body 430 is less than or equal to a predetermined size due to the rotation of the movable part 530. ) Is limited to rotate the ratchet gear 520, so that the tension between the first belt body 420 and the second belt body 430 can be maintained at a predetermined size. Therefore, if the tension between the first belt body 420 and the second belt body 430 is maintained at a certain size, it is possible to prevent the load from being fixed by preventing the load from being fixed by excessive tension. .

It is preferable that a protrusion 537 for separating the ratchet gear rotation preventing part is provided at the upper end of the movable part 530 to separate the ratchet gear rotation preventing part 515 from the teeth of the ratchet gear 520.

When the installation height of the ratchet gear rotation limiting part rising spring 536 is increased, the length of the ratchet gear rotation limiting part 535 is constant, so that the elastic force to energize the ratchet gear rotation limiting part 535 increases. . When the elastic force to support the ratchet gear rotation limiting part 535 increases, the contact force of the ratchet gear rotation limiting part 535 in contact with the teeth of the ratchet gear 520 increases, and accordingly, the first belt body It is possible to increase the tension between the 420 and the second belt body 430.

On the contrary, if the installation height of the ratchet gear rotation limiting part rising spring 536 is lowered, the length of the ratchet gear rotation limiting part 535 is constant, so that the elastic force to touch the ratchet gear rotation limiting part 535 is It becomes small. When the elastic force for pressing the ratchet gear rotation limiting part 535 decreases, the contact force of the ratchet gear rotation limiting part 535 in contact with the teeth of the ratchet gear 520 decreases, and thus the first belt body It is possible to reduce the tension between the 420 and the second belt body 430.

In this way, the present invention adjusts the elastic force by adjusting the installation height of the ratchet gear rotation limiting portion rising spring 536 by the ratchet gear rotation limiting portion rising spring elastic adjusting portion 540, the first belt body It is possible to adjust the tension between the 420 and the second belt body 430.

When the ratchet gear rotation limiting spring spring elastic adjustment bolt 543 is raised by tightening the ratchet gear rotation limiting spring spring elastic adjustment bolt 543 to the nut 542, coupled to the guide 544 When the lifting part 545 rises, and the lifting part 545 rises, the ratchet gear rotation limiting part lifting spring 536 mounted on the lifting part 545 is compressed to reduce the length. The elastic force of the ratchet gear rotation limiting spring 536 for rising is increased.

On the contrary, when the ratchet gear rotation limiting portion rising spring elastic adjusting bolt 543 is lowered by loosening the ratchet gear rotation limiting portion rising spring elastic adjusting bolt 543 to the nut 542, the guide 544 The combined lifting part 545 descends, and when the lifting part 545 descends, the ratchet gear rotation limiting part lifting spring 536 mounted on the lifting part 545 is stretched and the length is long. As a result, the elastic force of the ratchet gear rotation limiting spring 536 for raising is reduced.
