Description

Field of invention

[0001] The present invention relates to a method for strapping objects and in particular a method for strapping objects which can be operated by a single person and in which the two right-angled protective elements do not fall off after being placed on the object. State of the art

[0002] It will be directed to the Fig. 14 and Fig. Reference is made to Figure 15, which shows a conventional method for strapping objects. For example, an object 82 located on a transport pallet 81 is strapped. The simplified process is described below: Step 1: Moving a strapping machine 83, partially inserting an L-shaped strap guide section 831 and bringing it out of the underside of the transport pallet 81, so that the L-shaped strap guide section 831 dispenses a strapping band 832 over the underside of the transport pallet 81. Step 2: Place two right-angled protective elements 84 onto the object 82. Step 3: Pull out the strapping band 832, wrap it around the object 82 and the two right-angled protective elements 84 and reinsert one end of the strapping band 832 into the L-shaped band guide section 831. Step 4: Tightening, cutting and gluing the strapping band 832 using the existing functions (known technique, therefore not described in detail) of the strapping machine 83. Step 5: The conventional method for strapping objects, in which the two right-angled protective elements 84 are placed on the object 82, is finally completed.

[0003] However, since the two right-angled protective elements cannot be limited by the strapping band, in steps 2 to 4, when placing these two right-angled protective elements on the object, a worker must specifically press and fix them with both hands to prevent them from coming loose or slipping, which is very tedious.

[0004] This means that the above conventional method requires one operator (one worker) to control the strapping machine, and another operator (another worker) to press and fix the two right-angled protective elements with both hands, so two workers are required and thus the need for workers for strapping is relatively high.

[0005] Against this background, it is necessary to develop a technique that can remedy the above shortcomings in the state of the art. Object of the invention

[0006] It is an object of the present invention to provide a method for strapping objects which has the advantages that the two right-angled protective elements do not fall off after being applied and that the method can be operated by a single person. The problem to be solved by the present invention is, in particular, that the conventional method requires one worker to control the strapping machine and another worker to press and fix the two right-angled protective elements with both hands, thus requiring two workers and consequently a relatively high number of workers for strapping.

[0007] The technical means to solve the above-mentioned problem consists of providing a method for strapping objects, which includes the following steps: 1. Preparation step; 2nd shift step; 3. First band supply step; 4. Turning step; 5. First tightening step; 6. Second band supply step; 7. Manual insertion step; 8. Second tightening step; and 9.

Detailed description of the exemplary embodiment

[0008] It will be directed to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10 and Fig. 11 Reference is made to this. The present invention relates to a method for strapping objects and comprises the following steps: Preparation step S1: Preparing an object 10, a transport pallet 20, a strapping machine 30 and at least two right-angled protective elements 40, wherein the object 10 has a top 11, a bottom 12 and side sides 13 (see the Fig. 12 and Fig. 13) has a top surface 11 having a first edge 111 and a second edge 112, and the object 10 is placed with its bottom surface 12 on the transport pallet 20, the transport pallet 20 having a lower space 21, the strapping machine 30 being provided with several movable rollers 31, a strap supply section 32, a forward / reverse strap control 33, a strap cutting and gluing section 34, and an L-shaped strap guide section 35, the several movable rollers 31 serving to support and move the strapping machine 30, the strap supply section 32 serving to provide a strapping band 91, the strapping band 91 having a supply end 911, the supply end 911 being pulled out of the strap supply section 32 and successively passed through the forward / reverse strap control 33 and the strap cutting and gluing section 34, and finally on the L-shaped belt guide section 35 is arranged,the L-shaped tape guide section 35 has a tape output section 351, a tape return section 352 and a stop section 353 and the supply end 911 is arranged at the tape output section 351; Shifting step S2: Moving the strapping machine 30 by means of the several movable rollers 31, whereby the strap output section 351 of the L-shaped strap guide section 35 is guided through the lower space 21 (as shown in the Fig. 2 and Fig. 3 shown); First strap supply step S3: Controlling the forward / reverse strap control 33 to carry out the strap supply so that the supply end 911 of the strapping band 91 protrudes from the strap output section 351 (as in Fig. 3 shown); Laying step S4: Pulling the strapping band 91 using the supply end 911, whereby the strapping band is first placed around the object 10, then the supply end 911 is inserted into the band return section 352 and attached to the stop section 353 (this part is a known technique, which is why it is not described in detail here), whereby the strapping band 91 is placed around the object 10 (as in Fig. 4 shown); First tightening step S5: Controlling the forward / reverse strap control 33 so that the object 10 is secured with the strapping band 91 (the actual movement is a pulling backwards) and thus the strapping band 91 is tightly tightened around the object 10 (as in Fig. 5 shown); Second strap supply step S6: The forward / reverse strap control 33 is again controlled to perform an automatic strap supply, whereby the strapping band 91 (for strap supply) is pulled out of the strap supply section 32 by a first length, thereby providing a first insertion space G1 between the strapping band 91 and the first edge 111 and a second insertion space G2 between the strapping band 91 and the second edge 112 (as shown in Fig. 6 shown); Manual insertion step S7: Inserting the at least two right-angled protective elements 40 into the first insertion space G1 and the second insertion space G2, wherein the two right-angled protective elements 40 are limited by the strapping band 91 and therefore do not fall down (as in Fig. 7 shown; here the first insertion space G1 and the second insertion space G2 are omitted); Second tightening step S8: The forward / reverse strap control 33 is again controlled to automatically tighten the strapping band 91, thereby lashing the strapping band 91 tightly around the object 10 and the two right-angled protective elements 40 (as in Fig. 8 shown); Tape cutting and gluing step S9: Control the tape cutting and gluing section 34 to cut off the other part of the overlapping portion of the strapping band 91 located near the supply end 911 and then perform a hot melt gluing on the overlapping portion (as shown in the Fig. 9, Fig. 10 and Fig. 11) and thus complete the strapping process of objects.

[0009] In practice, the first length of the S6 ligament in the second step of band replacement can be between 12 and 18 cm.

[0010] The key point to emphasize is that the conventional method for strapping items on a transport pallet requires an operator to run the strapping machine. The L-shaped guide section of the strapping machine is inserted into the space beneath the pallet. The feed section is then controlled to dispense a strapping band. This band is then fed through the L-shaped guide section, wrapped around the pallet and the item, and inserted and secured within the guide section to pre-tighten the strapping around the item. Finally, the strapping band must be withdrawn from the feed section, leaving a gap between the strapping band and the item.The key point is that another worker needs to place the two right-angled protective elements onto the object and press and secure them with their hands (the worker may move away) to prevent loosening or slippage. Subsequently, the worker operating the strapping machine controls the strapping band so that it is tightened tightly around the object and the two right-angled protective elements. Therefore, two workers are required, and the labor requirement for strapping is relatively high.

[0011] The present invention aims to solve the aforementioned problems and comprises the second strap supply step and the second tightening step. After the strapping band 91 has been tightly tightened around the object 10 (namely, after the first tightening step S5), a special design ensures that the forward / reverse strap control 33 is controlled such that the strapping band 91 (serving for strap supply) is "automatically" pulled out of the strap supply section 32 by a first length, thereby creating a first insertion space G1 between the strapping band 91 and the first edge 111 and a second insertion space G2 between the strapping band 91 and the second edge 112 (as shown in Figure 1). Fig. 6). In this step, automatic control takes place and it requires no additional labor. Subsequently, the operator controlling the strapping machine can insert the two right-angled protective elements 40 into the first insertion space G1 and the second insertion space G2, respectively, whereby the two right-angled protective elements 40 are confined by the first insertion space G1 and the second insertion space G2 and cannot fall out (as shown in Fig. 7). Subsequently, the forward / reverse belt control 33 is again controlled to tighten the strapping band 91 (this is also an automatic control, not a manual operation). Finally, the strapping band 91 is tightly lashed around the object 10 and the two right-angled protective elements 40 (as shown in Fig. 8 shown).

[0012] Furthermore, the number of right-angled protective elements can also be four (as in Fig. 12) and are arranged in pairs on object 1 (as shown in Fig. 13 shown).

[0013] The advantages and beneficial effects of the present invention can be summarized as follows: [1] After application, the two right-angled protective elements do not fall off. In the second strap supply step of the present invention, the forward / reverse strap control is controlled such that it automatically extends the strapping band by a first length, thereby creating a first insertion space and a second insertion space between it and an object. In addition to the convenience of applying the two right-angled protective elements, the strapping band limits the two right-angled protective elements and prevents them from falling off (in principle, securing them with both hands after application is not necessary). Therefore, the two right-angled protective elements cannot fall off after application; [2] The present invention can be operated by a single person. In contrast to the conventional strapping machine, which requires two people to work together, the present invention requires only one person, so that the personnel requirement for the strapping process is relatively low and the invention can be operated by a single person.
