Article baling method

Abstract

The method comprises a preparation step, a moving step, a first tape supply step, an article surrounding step, a first tensioning step, a second tape supply step, a manual insertion step, a second tensioning step and a tape cutting and bonding step. According to the steps, an article is placed on a pallet, a belt outlet part of a banding machine extends below the pallet, and a banding belt supplied by the belt outlet part bypasses the article and then is inserted back to the banding machine to be fixed. The method comprises the following steps: firstly, controlling a tape feeding and discharging control part of the banding machine to tension a banding tape to be tightly wound on an object, and then controlling the tape feeding and discharging control part to automatically pull out the banding tape, so that two insertion spaces are formed between the banding tape and the object. The two right-angle protection pad elements can be inserted into the two insertion spaces respectively and cannot fall off due to the limitation of the bundling belt, and then the bundling belt is tightened to tightly wind the article and the two right-angle protection pad elements; and then, the belt is cut and bonded to complete the article bundling action. According to the scheme, the two right-angle protection pad elements do not fall off after being placed and can be operated by a single person.

Description

Technical Field

[0001] The invention relates to a method for bundling articles, and in particular to a method for bundling articles in which two right-angled cushion elements will not fall off after being placed and can be operated by a single person. Background Art

[0002] like Fig.14 and Fig.15 As shown, it is a traditional method of bundling articles. For example, for bundling an article 82 on a pallet 81, the simplified process is as follows:

[0003] Step 1: First, move a strapping machine 83 so that its L-shaped guide belt portion 831 is partially inserted into and then extended from under the pallet 81 ; that is, the L-shaped guide belt portion 831 can output a strapping belt 832 from under the pallet 81 .

[0004] Step 2: Place two right-angle pad elements 84 on the object 82.

[0005] Step 3: Pull out the packing belt 832 and wrap it around the object 82 and the two right-angle pad elements 84 , and insert one end of the packing belt 832 back into the L-shaped belt guide 831 .

[0006] Step 4: Reuse the existing functions of the strapping machine 83 (known technology, not described in detail) to tighten, cut and bond the strapping belt 832.

[0007] Step 5: Finally, the conventional article packaging process of placing two right-angle cushion elements 84 on the article 82 is completed.

[0008] However, during the process from step 2 to step 4, when the two right-angled cushion elements are placed on the article, since the strapping belt cannot restrain the two right-angled cushion elements, the two right-angled cushion elements must be pressed and fixed by one person with both hands to prevent them from loosening or sliding off, which is very troublesome.

[0009] That is, the conventional method requires one operator (one manpower) to control the strapping machine, and another operator (another manpower) to hold down and fix the two right-angle pad elements with both hands, which is equivalent to requiring two manpowers, and the strapping manpower requirement is relatively high.

[0010] In view of this, it is necessary to develop a technology that can solve the above-mentioned existing shortcomings. Summary of the invention

[0011] The purpose of the present invention is to provide a method for bundling articles, which has the advantages that two right-angle pad elements will not fall after being placed and can be operated by a single person. In particular, the present invention solves the problem that the traditional method requires one person to operate the bundling machine and another person's hands to press and fix the two right-angle pad elements, which means that two people are required, and the bundling manpower requirements are relatively high.

[0012] The technical means to solve the above problem is to provide a method for bundling articles, comprising the following steps:

[0013] 1. Preparation steps:

[0014] 2. Moving steps;

[0015] 3. First tape supply step;

[0054] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 The present invention is a method for packaging articles, comprising the following steps:

[0055] 1. Preparation step S1: Prepare an object 10, a pallet 20, a strapping machine 30 and at least two right-angle pad elements 40. The object 10 has a top surface 11, a bottom surface 12 and four side surfaces 13 (see FIGS. 12 and 13), the top surface 11 has a first edge 111 and a second edge 112; the object 10 is placed on the pallet 20 with the bottom surface 12. The pallet 20 has a bottom space 21. The strapping machine 30 is provided with a plurality of movable wheels 31, a belt supplying part 32, a belt advancing and retreating control part 33, a belt cutting and bonding part 34, and an L-shaped belt guide part 35. The plurality of movable wheels 31 are used to carry the strapping machine 30 for movement; the strap supply unit 32 is used to provide a strapping strap 91, and the strapping strap 91 has a supply end 911, which can be pulled out from the strap supply unit 32, and sequentially passes through the advance and retreat strap control unit 33, the strap cutting and bonding unit 34, and finally is disposed on the L-shaped strap guide unit 35. The L-shaped strap guide unit 35 has a strap outlet unit 351, a strap return unit 352, and a stop unit 353, and the supply end 911 is disposed on the strap outlet unit 351.

[0056] Second, the moving step S2: the strapping machine 30 is moved by the plurality of movable wheels 31, so that the belt outlet portion 351 of the L-shaped belt guide portion 35 extends into the bottom space 21 (such as Figure 2 and Figure 3 shown).

[0057] 3. First tape supply step S3: Control the tape advance / retract control unit 33 to supply tape so that the supply end 911 of the strapping tape 91 extends out of the tape outlet unit 351 (such as Figure 3 shown).

[0058] 4. Wrapping the Article Step S4: After the strapping belt 91 is pulled by the supply end 911 to wrap around the article 10, the supply end 911 is inserted into the belt return portion 352 and fixed to the stopper portion 353 (this part is a known technology and will not be described in detail, but will be described first). Figure 4 shown).

[0059] 5. First tightening step S5: First, control the advance / retract belt control unit 33 to tighten (actually pull) the strapping belt 91 so that the strapping belt 91 is tightly wound around the article 10 (such as Figure 5 shown).

[0060] 6. Second tape supply step S6: Control the tape advance / retract control unit 33 to automatically supply tape, and pull the strapping tape 91 out of the strapping tape supply unit 32 (supply tape) by a first length; so that a first insertion space G1 is provided between the strapping tape 91 and the first edge 111; and a second insertion space G2 is provided between the strapping tape 91 and the second edge 112 (such as Figure 6 shown).

[0061] 7. Manual insertion step S7: inserting the at least two right-angled pad elements 40 into the first insertion space G1 and the second insertion space G2 respectively, and the two right-angled pad elements 40 are restrained by the packing belt 91 and will not fall off (e.g. Figure 7 As shown, and Figure 7 In the figure, the first insertion space G1 and the second insertion space G2 are omitted and not shown, and are described first. ).

[0062] 8. Second tightening step S8: Control the advance and retreat belt control unit 33 to automatically tighten the strapping belt 91, so that the strapping belt 91 is tightly wound around the article 10 and the two right-angle pad elements 40 (such as Figure 8 shown).

[0063] 9. Cutting and bonding step S9: Control the cutting and bonding unit 34 to first cut the portion of the strapping strap 91 other than the overlapping portion adjacent to the delivery end 911, and then perform hot-melt bonding on the overlapping portion (e.g. Fig. 9 , Fig.10 and Fig.11 As shown), the action of bundling items is completed.

[0064] In fact, in the second tape supplying step S6, the first length may be between 12 and 18 centimeters.

[0065] The part that needs to be specially explained here is that the traditional method of bundling items on a pallet requires a person to operate the strapping machine, insert the L-shaped belt guide of the strapping machine into the bottom space under the pallet, and then control the belt supply part to supply the strapping belt. The strapping belt is output through the L-shaped belt guide part, and then it is passed through the L-shaped belt guide part and fixed to the L-shaped belt guide part after it is wrapped around the pallet and the item. Then, the strapping belt needs to be pulled out from the belt supply part so that there is a gap between the strapping belt and the item. The key point is that another person must place the two right-angle pad elements on the item, and press and fix them with both hands of the other person (cannot leave) to prevent them from loosening or slipping. Then, the person who controls the strapping machine controls the strapping belt to tighten it, so that the strapping belt can be tightly bound to the item and the two right-angle pad elements. That is, two operating people are required, and the strapping manpower requirements are relatively high.

[0066] In view of the above-mentioned problem, the second supplying step and the second tightening step are designed in this case. After the strapping belt 91 is tightly wound around the article 10 (i.e., the first tightening step S5), the strapping belt control unit 33 is specially designed to "automatically" pull the strapping belt 91 out of the strapping belt supply unit 32 (supply the strap) by the first length; so that a first insertion space G1 is provided between the strapping belt 91 and the first edge 111; and a second insertion space G2 (such as the second insertion space G3) is provided between the strapping belt 91 and the second edge 112. Figure 6 This step is automatically controlled and does not require additional human operation. Then, the human power of the strapping machine can be controlled to insert the two right-angle pad elements 40 into the first insertion space G1 and the second insertion space G2 respectively, and the two right-angle pad elements 40 are restrained by the strapping belt 91 and will not fall off (as shown in FIG. Figure 7 Then, the advance and retreat belt control unit 33 is controlled again (automatically, without manual operation) to tighten the strapping belt 91, and finally the strapping belt 91 is tightly wound around the article 10 and the two right-angle pad elements 40 (as shown in FIG. Figure 8 shown).

[0067] Further, the two right-angle pad elements 40 (such as Fig.12 As shown) there may also be four, and they are arranged on the article 10 in pairs (as shown) Fig.13 shown).

[0068] The advantages and effects of the present invention can be summarized as follows:

[0069] 1. The two right-angle cushion elements will not fall after being placed. In the second belt supply step of this case, the advance and retreat belt control unit is controlled to automatically pull the strapping belt out to the first length; thereby generating the first insertion space and the second insertion space between the strapping belt and the article, which not only facilitates the insertion of the two right-angle cushion elements; the two right-angle cushion elements are restricted by the strapping belt and will not fall (in principle, both hands are not required to fix them after insertion). Therefore, the two right-angle cushion elements will not fall after being placed.

[0070] 2. Single-person operation is possible. Compared with the traditional strapping machine which requires two people to operate, this case only requires one person, and the strapping manpower requirement is relatively low. Therefore, single-person operation is possible.
