The present invention relates to a method for packing an article, in particular to the method for packing an article on a pallet that can be operated by a single person and without the falling of two right-angle pad elements after being placed.
As shown in
Step 1: at first, moving a strapping machine 83 and partially inserting an L-shaped strap guiding portion 831 thereof and then extending below the pallet 81; that is, the L-shaped strap guiding portion 831 can output a packing strap 832 from the bottom of the pallet 81.
Step 2: placing two right-angle pad elements 84 on the article 82.
Step 3: pulling the packing strap 832 out and wrapping around the article 82 and the two right-angle pad elements 84, and inserting one end of the packing strap 832 back into the L-shaped strap guiding portion 831.
Step 4: utilizing the existing functions of the strapping machine 83 (known technology, not described in detail) to tighten, cut and bond the packing strap 832.
Step 5: finally, completing the conventional bundling of placing two right-angle pad elements 84 on the article 82.
However, in the process of steps 2 to 4, when the two right-angle pad elements are placed on the article, the two right-angle pad elements cannot be restrained by the packing strap. Therefore, the two right-angle pad elements must be pressed and secured by two hands of one person (or operator) so as to prevent loosening or falling down, which is very troublesome.
Hence, the above-mentioned conventional method requires an operator (one person) to control the strapping machine and requires another operator (another person) to press and secure on the two right-angle pad elements with both hands at the same time. Under this condition, two operators (or two persons) are required. It means the manpower requirement for such packing work is relatively high.
Therefore, it is necessary to develop a new technology that can solve the above-mentioned conventional shortcomings.
The purpose of the present invention is to provide a method for packing an article, which has the advantages of two right-angle pad elements that will not fall after placement and can be operated by a single person. In particular, the problem to be solved by the present invention is that in the conventional method, one person is required to control the strapping machine, and another person's hands are required to press and secure on the two right-angle pad elements, which means two persons are required; and the manpower requirement for such packing work is relatively high.
The technical means to solve the above problems is to provide a method for packing an article, which includes the following steps:
Referring to
1. preparing step S1: preparing an article 10, a pallet 20, a strapping machine 30, and at least two right-angle pad elements 40. The article 10 has a top surface 11, a bottom surface 12, and four side surfaces 13 respectively arranged thereon (referring to
2. moving step S2: moving the strapping machine 30 by the plurality of movable wheels 31, and then making the strap outlet portion 351 of the L-shaped strap guide unit 35 extend into the bottom space 21 (as shown in
3. first time feeding strap step S3: controlling the strap feeding and retreating control unit 33 to feed the packing strap 91 so that the supply end 911 of the packing strap 91 extends out of the strap outlet portion 351 (as shown in
4. encircling article step S4: pulling the packing strap 91 through the supply end 911 to wrap around the article 10 first, then passing the supply end 911 into the strap return portion 352, and fixing on the stopper portion 353 (it is stated here that this technology is a known technology and will not be described in detail), so that the packing strap 91 surrounds the article 10 (as shown in
5. first time tightening step S5: first controlling the strap feeding and retreating control unit 33 to tighten (the actual action is to pull backwards) the packing strap 91, so that the packing strap 91 is tightly wrapping around the article 10 (as shown in
6. a second time feeding strap step S6: controlling the strap feeding and retreating control unit 33 to automatically supply strap and pulling out (or called feeding) the packing strap 91 from the strap supply unit 32 to a first length so as to generate a first insertion space G1 between the packing strap 91 and the first edge 111, and a second insertion space G2 between the packing strap 91 and the second edge 112 (as shown in
7. manual inserting step S7: inserting the at least two right-angle pad elements 40 (to protect to the article 10 from packing strap's pressing/damaging) into the first insertion space G1 and the second insertion space G2, respectively, wherein the two right-angle pad elements 40 are all limited by the packing strap 91 and will not fall down (as shown in
8. second time tightening step S8: controlling the strap feeding and retreating control unit 33 to automatically tighten the packing strap 91, so that the packing strap 91 is tightly wrapping around the article 10 and the two right-angle pad elements 40 (as shown in
9. strap cutting and bonding step S9: controlling the strap cutting and bonding unit 34 to cut off and form an overlapping portion adjacent to the supply end 911 and to bond the overlapping portion via thermal bonding (as shown in
Practically, in the second time feeding strap step S6, the first length can be between 12-18 cm (which is suitable for most packing works on a regular-sized pallet).
Furthermore, the conventional method for packing an article on the pallet requires one specific person to operate the strapping machine exclusively. First, the L-shaped strap guide unit of the strapping machine inserts into the bottom space under the pallet, and then control the strap supply unit to supply the packing strap. Next, the packing strap is output through the L-shaped strap guide unit, and after one circle around the pallet and the article, the packing strap is inserted into and secured on the L-shaped strap guide unit, so that the packing strap is tightly wrapped around the article. Next, it is necessary to pull out the packing strap from the strap supply unit to create a gap between the packing strap and the article. The key point is that another person must place the two right-angle pad elements on the article and press and fix them with the hands of the other person (the hands have to keep pressing on) to prevent loosening or slipping. Then, the person who controls the strapping machine controls the packing strap to tighten so that the packing strap can be tightly tied to the article and the two right-angle pad elements. That is, two operators are necessary, and the manpower requirement for such packing work is relatively high in a conventional way.
However, in order to solve the aforementioned conventional problem, this invention is designed to include the second time feeding strap and the second time tightening step. After the packing strap 91 is tightly wrapping around the article 10 (that is, the first time tightening step S5), the present invention is specially designed to first control the strap feeding and retreating control unit 33 to “automatically” pull (or called feed) the packing strap 91 out of the strap supply unit 32 (supply strap) to the first length, so that a first insertion space G1 is generated between the packing strap 91 and the first edge 111, and a second insertion space G2 is generated between the packing strap 91 and the second edge 112 (as shown in
Furthermore, the two right-angle pad elements 40 (as shown in
The advantages and effects provided by the present invention may include the following:
1. The two right-angle pad elements will not fall down after being placed. In the second time feeding strap step of the present invention, the strap feeding and retreating control unit is controlled to automatically pull the packing strap out of the first length. Further, the first insertion space and the second insertion space are generated between the article and the packing strap; in addition to facilitating the insertion of the two right-angle pad elements, the two right-angle pad elements are restricted by the packing strap and will not fall down (in principle, no hands are needed for fixing after insertion). Therefore, the two right-angle pad elements will not fall down after being placed.
2. It can be operated by one person only. Compared with the conventional strapping machine that requires two persons to work together, the present invention only needs one person, so the manpower requirement for such packing work is relatively low. Therefore, it can be operated by a single person.
