Description

Technical Field

[0001] This invention relates to a method for manufacturing endless chain sheets, and particularly to a method for manufacturing multiple rows of endless chain sheet cushioning material on a pallet. Background Technology

[0002] background

[0003] Typically, the width of chain sheet material forming cushioning products is approximately 70 to 76 cm or 28 to 30 inches to fit common EUR pallets with a width of 80 cm. This is the optimal method for stacking several rows or bundles of continuous chain sheet material within limited unused transport and storage space, maximizing the possible run meters of the continuous chain sheet material for direct feeding into the cushioning distributor, as if from a continuous pallet. The total pallet height, including several rows or stacked bundles of chain sheet material, can reach 110 cm (including pallet height). This is the optimal method for stacking several rows or bundles of continuous chain sheet material within limited unused transport and storage space, maximizing the possible run meters of the continuous chain sheet material for direct feeding into the cushioning distributor, as if from a continuous pallet.

[0004] For narrower chain sheet materials, such as 15 inches, they can be stacked in two rows on a pallet, each requiring a separate feed and buffer distributor position. However, this necessitates multiple manual feed handles and adjustments to the buffer distributor or the position of the continuous pallet. Summary of the Invention

[0041] Detailed description

[0042] The invention will now be described in more detail with reference to the following embodiments. It should be noted that the following description of preferred embodiments of the invention is for illustrative and descriptive purposes only; they are not exhaustive, nor are they limited to the precise forms disclosed.

[0043] Please refer to Figure 1 The illustration depicts an embodiment of a first package or first row of chain sheet material 1 according to the invention, which is positioned on a tray 100. Those skilled in the art will understand that a row can be formed by N packages of chain sheet material, where N ≥ 2. Figure 2 The diagram shows Figure 1 A similar concept to the illustrated embodiment, except that the chain sheet material is a pre-configured or pre-folded chain sheet material 2. The width of the chain sheet material 1 or the pre-configured or pre-folded chain sheet material 2 is approximately half the width of the tray 100. For example, the width of the chain sheet material 1 or the pre-configured or pre-folded chain sheet material 2 is approximately 15 inches, and the width of the tray 100 is 30 inches.

[0044] exist Figure 1 and Figure 2The chain sheet material 1 or pre-configured or pre-folded chain sheet material 2 below the first package in the first row can be folded into several bottom sheets, i.e., the lower part 3 of the first package, so as to connect to the second row in the first layer, or to make the total height of the layer of packages or rows a predetermined height, such as 1.1 meters.

[0045] refer to Figure 3A and Figure 3B The diagram shows a pre-configured or pre-folded chain sheet material 2, with the sheet 5 near the bottom 4 of the first package or row folded inward or at an angle to form a first folded portion 301 of the lower portion 3, so that the remaining portion of the pre-configured or pre-folded chain sheet material 2 can be placed beside it on the tray 100. In another embodiment, the sheet 5 can be folded outward. Figure 4 The method shown is to position the upper part 6 of the first package in the first row on the tray 100 and place the remaining sheet 7 of the pre-configured or pre-folded chain sheet material 2 next to it.

[0046] refer to Figure 5 The figure illustrates a method for positioning the first bundle 9 of the first layer of chain-like sheet material on a pallet 100 along the first row 8, wherein the top sheet 10 of the first bundle 9 can be connected or spliced ​​along the longitudinal direction X of the pallet 100 to the bottom sheet of the next bundle (not shown) in the first row 8, as shown. Figure 4 As shown.

[0047] As mentioned earlier, the sheet material on the pallet can reach a total height of approximately 1.1 meters. Therefore, a chain of sheet material can consist of tall bundles, each of which can reach a height of approximately 1 meter, such as... Figure 6 As shown. Alternatively, several small packages of chain-linked sheet material can be stacked to a total height of approximately 1.1 meters, such as... Figure 7 As shown. The last upper sheet 11 of the continuous chain sheet material 1 can be the sheet that will be supplied to the buffer distributor (not shown).

[0048] As mentioned above Figure 5 As shown, Figure 6 or Figure 7 The top sheet of the nth package in a row can be connected or spliced ​​to the bottom sheet of the (n+1)th package using single-sided tape or glue, or double-sided tape or glue, where n = 1, 2, ..., N-1. Furthermore, for multi-layered chain-like sheet materials, separate rows of different layers can also be connected to each other by connecting or splicing the top sheet of the Nth package of each layer to the bottom sheet of the first package of the next or upper layer using single-sided tape or glue, or double-sided tape or glue.

[0049] In another embodiment, for Figure 7In a multi-layered arrangement of chain-link sheet materials, such as L layers, the top sheet of the nth package in the Lth layer can be connected or spliced ​​to the bottom sheet of the (n+1)th package in the Lth layer, where n = 1, 2, ..., N-1 and L ≥ 2. Furthermore, the top sheet of the Nth package in the lth layer can be connected or spliced ​​to the bottom sheet of the nth package in the (l+1)th layer, where n = 1, 2, ..., N and l = 1, 2, ..., L-1.

[0050] Figure 8 The prepared bottom sheet 12 of the first package 9 is shown being placed on top in preparation for attaching to the second row 13 of the package when the second row 13 is placed beside it, as shown. Figure 9 As shown. In Figure 5 After the first package 9 of the first layer mentioned above is positioned along the first row 8, the additional packages and layers have been arranged according to... Figure 7 The method described herein is used for positioning. The preparatory bottom sheet 12 of the first package 9 includes an end portion 304 and an intermediate portion 302 connecting the end portion 304 and the first fold portion 301. Obviously, the intermediate portion 302 of the first package 9 should have sufficient length to place the end portion 304 on top of the first package of the first row 8 of the Lth layer (i.e., the top layer).

[0051] refer to Figure 9 An embodiment of a layer of chain sheet material is shown, comprising two rows placed on a tray 100 in the transverse direction Y. Taking the bottom layer as an example, the second row 13 of the bottom layer is located next to the first row of the same layer. Furthermore, the arrangement direction from the first package in the first row to the Nth package can be the same as or opposite to the arrangement direction from the first package in the second row to the Nth package. Additionally, if the width of the chain sheet material 1 or the pre-configured or pre-folded chain sheet material 2 is approximately 10 inches or less, the number of rows in a layer can be three or more. Where applicable, the same concept can be applied to more rows in a layer.

[0052] Figures 10A to 10C Some folding methods for chain-like sheet materials according to embodiments of the present invention are shown. Figure 10A and Figure 10B In the middle, the bottom sheet 14 of the first row on the left is folded to connect to the second row on the right, wherein a second folded portion 303 is formed between the end portion 304 and the middle portion 302. It is also clear that the middle portion 302 of the first package 9 should have sufficient length to place the second folded portion 303 on top of the first package in the second row 13 of the Lth layer (i.e., the top layer). Figure 10C In the chain sheet material, the folded flat position 15 of the folded sheet or layer is located at the top of the second row, and the top sheet 16 of the Nth package of the second row 13 is folded or flipped back at the top of the second row 13 so as to connect with the end portion 304 of the first package 9.

[0053] Some practices are applicable to connecting or splicing chain-like sheet materials to form a coherent sheet of material. Figure 11-13B The illustrations show some exemplary embodiments of the connection of a sheet consisting of four layers, and each embodiment includes two rows of four packages placed in parallel on a tray. Figure 11 In this configuration, the end portion of the first bundle 9 of the first row of chain-link sheet material (e.g., the bottom sheet) is configured to connect to the second row of top layer sheet 17. Figure 12 In this configuration, the bottom sheet 19 of the first bundle 9 of the first layer of pre-configured or pre-folded sheet material from the first row of chain sheet material is configured to connect to the top sheet 18 of the second row. Figures 13A-13B In this embodiment, the bottom sheet 21 of the first bundle of two pre-configured or pre-folded sheets from the first row of continuous chain sheet material is configured to connect to the top sheet 20 of the second row. The one-layer or two-layer pre-configured or pre-folded sheets of the chain sheet material can be prepared by pre-treating the chain sheet material before it is positioned on the pallet. Again, according to the above embodiment, only one sheet of the chain sheet material needs to be fed to the buffer dispenser without requiring a new feed. Therefore, the present invention provides a maximum running length of continuous chain sheet material on a pallet.

[0054] It is possible that an excessively tall row or multiple rows consisting of packages of narrow, continuous chain sheet material may tilt during manufacturing, transport, or transfer through a buffer distributor. Tension on the web of the chain sheet material can cause tearing (resulting in rows up to 1 meter high). Therefore, a row or multiple rows consisting of multiple packages on a continuous pallet may need to be manufactured from lower rows. This invention provides a method for positioning narrow, continuous material packages on a pallet to reduce the chance of web tilting or tearing. Reference Figure 14A and Figure 14B This illustrates a method for positioning the first layer of a package of two rows of chain-linked sheet material on a tray. In one embodiment, the two rows of packages in the same layer are approximately the same height. The bottom sheet 25 of the first package of the first row in the first layer is positioned on top of the first package. Utilizing a similar concept described in the preceding section, the first and second rows of chain-linked sheet material are placed parallel to each other on the tray 100. The sheet material may consist of M rows, where M ≥ 2. Figure 14B In this arrangement, after the first row 26 of the first layer has been positioned on the tray 100, the second row 27 of the first layer can be positioned next to the first row 26, that is, along the lateral direction Y of the tray 100. Furthermore, the arrangement direction extending from the first package in the first row to the Nth package can be the same as or opposite to the arrangement direction extending from the first package in the second row to the Nth package.

[0055] exist Figure 14CIn the text, a similar method of connecting or splicing the bottom of the first line with the top of the second line (e.g.) Figures 10A-10C (As shown) This can be applied to the first row 26 and the second row 27. Similarly, if applicable, a single layer of chain sheet material can include more rows, which makes the entire chain sheet material tray more stable.

[0056] refer to Figure 15A-15F This illustrates some embodiments of two-layered, row-shaped packages of chain-linked sheet material positioned on a pallet. Figure 15A In the process, a new layer is formed on top of the first layer of the two rows, and the bottom sheet 29 of the first package of the first row in the second layer is placed on top of the first package of the first row in the first layer. Typically, if there are M rows, the bottom sheet of the first package of the m-th row in the second layer is placed on top of the first package of the m-th row in the first layer, where m = 1, 2, ..., M-1.

[0057] Figure 15B Shown from different angles Figure 15A The same chain-type sheet material tray is used, wherein the sheet (e.g., the bottom sheet) of the lower part 30 of the first package in the second row of the second layer is folded underneath. Typically, if there are N packages in each row, the lower part of the first package in the m-th row of the first layer can be connected to the upper part of the N-th package in the (m+1)-th row of the first layer, where m = 1, 2, ..., M-1. According to one embodiment of the invention, the lower part 30 includes an end portion 312 for connection to the top sheet of the N-th package in the first row 26 of the first layer, and a folded portion 311 connecting the end portion 312 to the upper part of the first package in the second row of the second layer. Figure 15C and Figure 15D As shown, the upper 31 of the Nth package in the first row 26 (e.g., the top sheet) is folded back or flipped over at the top of the first layer to be connected to the lower 30 of the first package in the second row at the second layer using tape or glue 32. Typically, if there are M rows and N packages in each row, the folded lower portion of the first package in the Mth row of the second layer can be connected or spliced ​​to the folded upper portion of the Nth package in the first row at the top of the first layer, thereby extending the running length of the continuous chain of sheet material from the first layer to the second layer.

[0058] In addition, Figure 15E and Figure 15F In the second layer, the remaining packages in the first row 33 or the second row 34 can then be positioned along the longitudinal direction of the pallet 100, and the first row 33 and the second row 34 of the second layer are approximately the same height. The arrangement direction from the first package in the first row to the Nth package can be the same as or opposite to the arrangement direction from the first package in the second row to the Nth package. A similar method of connecting or splicing the lower part of the first row to the upper part of the second row (e.g.) Figures 10A-10C(As shown) This can be applied to the first row 33 and the second row 34. In general, if there are M rows, each with N packets, after completing the connection between the first and second layers, the upper part of the nth packet in the mth row of the second layer can be sequentially connected to the lower part of the (n+1)th packet in the mth row of the second layer, where n = 1, 2, ..., N-1 and m = 1, 2, ..., M. Furthermore, the lower part of the first packet in the mth row of the second layer can be connected to the upper part of the Nth packet in the (m+1)th row of the second layer, where m = 1, 2, ..., M-1. Of course, by repeating the above connection method, the number of layers can be 3 or more.

[0059] Although the invention has been described according to what is now considered the most practical and preferred embodiments, it should be understood that the invention is not limited to the disclosed embodiments.

[0060] Industrial applicability

[0061] Through the above embodiments, it is possible to manufacture a continuous pallet chain sheet material with a running length equal to the running length of a 30-inch continuous pallet chain sheet material. Furthermore, the method of positioning the chain sheet material on the pallet prevents the material from tilting or tearing on the pallet, which is a major innovation in the art. In addition, the method of the present invention can provide full-height pallets, such as 1.1 meters high, using chain sheet material with a narrow width, requiring only a single feed. The results demonstrate that the present invention has good industrial applicability.
