Abstract

The present invention relates to a palletizing structure for spool-shaped products and a method for palletizing spool-shaped products. The palletizing structure includes: at least three stacks of spool-shaped products, in any one stack of spool-shaped products, any adjacent upper and lower layers of spool-shaped products are stacked in a flush manner; at least three stacks of spool-shaped products are arranged in at least two rows in the front-rear direction; at least three stacks of spool-shaped products form at least two sets of closely stacked units, and each closely stacked unit is formed by two adjacent stacks of spool-shaped products. Any two adjacent upper and lower products are stacked closely without other stacks of spool-shaped products sandwiched in between. If it is tilted due to the stacking and pressing of the unilateral wheel edges, the inclination angle of each layer is basically the same, and it will not show the situation where the inclination angles are gradually accumulated as in the existing alternating stacking, ensuring that the spool-shaped products will not collapse due to excessive inclination when the number of layers is not too high.

Description

Technical Field

[0001] The invention relates to a palletizing structure and a palletizing method for I-wheel type products. Background Art

[0002] As a typical I-shaped reel, metal basket reels are widely used. They are a common consumable in welding wire production, packaging, and handling. Compared to traditional plastic reels, metal basket reels offer advantages such as environmental friendliness and lower raw material costs.

[0003] In the Chinese invention patent with the authorization announcement number CN104985369B, a basket-type winding reel is disclosed, such as Figure 1 As shown, the winding drum 100 is an I-shaped product, formed by sequentially welding and splicing basket-like components 101. The winding drum has two side rims 102 to form an annular winding groove on the winding drum 100, which can be used to wind welding wire or wire rods in layers.

[0004] The formed metal basket-type winding reels are placed in the clamping fixture. The basket-type winding reels are large in size and light in weight. In the past, they were manually grabbed and stacked. Manual grabbing often causes uneven force around the metal basket-type winding reels, which easily leads to deformation and cracking. The subsequent manual stacking also increases labor costs. In addition, when manually stacking the winding reels one by one, adjacent winding reels of different stacks are stacked together in sequence. Simply put, Figure 2 As shown, for two adjacent stacks of winding drums, when stacking, first stack a right winding drum 200, then stack a left winding drum 201, then stack the right winding drum 200, and then stack a left winding drum 201, and so on. They are gradually raised back and forth in sequence to form an ABAB alternating stacking method, that is, between any two adjacent winding drums in the same stack, a side of the winding drums of other stacks is sandwiched.

[0005] The above-mentioned manual stacking method not only requires a lot of labor and high labor costs, but also has a great impact on the winding reels that are stacked later. Figure 2For the spool on the left stack in [description], the right wheel edge presses on the spool of the right stack on the same layer, and the left wheel edge presses on the base or on the spool of the lower layer in the same stack, resulting in the left side of the left stack of spools being lower than the right side, with the whole arranged obliquely; similarly, for the spool of the right stack, its left wheel edge presses on the wheel edge of the spool of the lower layer of the left stack, and the right wheel edge presses on the spool of the lower layer in the same stack. In this way, for the spool of the right stack, except for the spool of the bottom layer, the left wheel edges of all other spools will be higher than the right wheel edges, also arranged obliquely. Adjacent two stacks of spools are both arranged obliquely, and the corresponding side wheel edges of the spools of the adjacent stack are sandwiched between the spools of the upper and lower adjacent layers of any stack of spools. Not only will the inclination angle of each layer be relatively large, but also the height difference of each layer is likely to be accumulated, resulting in a larger inclination angle towards the upper part, and the overall palletizing is relatively loose, and the higher the number of layers, the easier it is to collapse. Summary of the Invention

[0006] The purpose of the present invention is to provide a palletizing structure for spool-shaped products, so as to solve the technical problem that when the spools of adjacent two stacks are alternately palletized in sequence in the prior art, the inclination angle of the stacked spools is likely to be too large; at the same time, the present invention also provides a method for palletizing spool-shaped products to realize the above palletizing structure.

[0007] To achieve the above purpose, the technical solution of the palletizing structure for spool-shaped products provided by the present invention is: a palletizing structure for spool-shaped products, including:

[0008] At least three stacks of spool-shaped products, in any stack of spool-shaped products, any adjacent upper and lower layers of spool-shaped products are stacked and palletized flush.

[0009] The at least three stacks of spool-shaped products are arranged in at least two rows in the front-back direction, with at least one stack of spool-shaped products arranged in each row, and at least two stacks of spool-shaped products are arranged in at least one row.

[0010] The at least three stacks of spool-shaped products form at least two sets of closely stacked units, and each closely stacked unit is formed by two adjacent stacks of spool-shaped products.

[0011] Among the two stacks of spool-shaped products belonging to the same closely stacked unit, one stack of spool-shaped products is all support members, and the other stack of spool-shaped products is all press-fitting members. The two stacks of spool-shaped products are horizontally inserted correspondingly, so that in any adjacent upper and lower press-fitting member and support member, the corresponding side wheel edge of the upper press-fitting member is stacked and press-fitted on the corresponding side wheel edge of the lower support member.

[0012] The beneficial effects are as follows: In the palletizing structure of spool-shaped products provided by the present invention, the spool-shaped products are stacked closely, so that any two adjacent products in each stack of spool-shaped products are stacked closely, and there are no other stacks of spool-shaped products in between. In the two adjacent stacks of spool-shaped products that form a closely stacked unit, when they are inclined due to the stacking and pressing of the wheel edges on one side, the inclination angles of each layer are basically the same, and there will be no situation where the inclination angles gradually accumulate as in the existing alternating stacking method. This ensures that the spool-shaped products will not collapse due to excessive inclination when the number of layers is not too high, facilitating automatic palletizing.

[0013] As a further improvement, the two stacks of spool-shaped products in at least one closely stacked unit belong to the front and rear rows respectively.

[0014] The beneficial effects are as follows: The spool-shaped products in the front and rear rows are horizontally inserted correspondingly to form a closely stacked unit, which is convenient for reducing the space occupied by the palletizing structure in the front and rear directions.

[0015] As a further improvement, each row of spool-shaped products includes at least three stacks of spool-shaped products arranged in sequence along the left-right direction. All the spool-shaped products in the same row are adjacent to each other in pairs in sequence to form at least two of the above-mentioned closely stacked units. All the spool-shaped products in the same row are arranged in an alternating manner of "supporting member - pressing member - supporting member" or in an alternating manner of "pressing member - supporting member - pressing member".

[0016] The beneficial effects are as follows: When at least three stacks of spool-shaped products are arranged in a single row, by arranging them in an alternating manner of supporting member - pressing member - supporting member or in an alternating manner of pressing member - supporting member - pressing member for the spool-shaped products, combined with the close stacking within a single stack, the pressing member can be in a state of being basically non-inclined or having a small inclination angle, which is convenient for ensuring the stability of the entire palletizing structure.

[0017] As a further improvement, all the spool-shaped products are arranged in multiple rows in sequence along the front-rear direction. When all the spool-shaped products in the same row are arranged in an alternating manner of "supporting member - pressing member - supporting member", the odd-numbered columns of spool-shaped products in each row are all the above-mentioned supporting members, and the even-numbered columns of spool-shaped products in each row are all the above-mentioned pressing members.

[0018] As a further improvement, in any two adjacent front and rear rows of spool-shaped products, the wheel edge of any odd-numbered column single-stack spool-shaped product in the rear row of spool-shaped products is correspondingly stacked and pressed on the wheel edge of a stack of spool-shaped products in the front row of spool-shaped products to form a corresponding closely stacked unit.

[0019] The beneficial effects are as follows: The spool-shaped products in the front and rear rows are horizontally inserted correspondingly to form a closely stacked unit, which can not only reduce the horizontal floor area of the palletizing structure, but also improve the overall strength of the entire palletizing structure.

[0020] As a further improvement, the spool-shaped product is a metal basket-type wire winding reel.

[0021] The technical solution of the method for palletizing spool-shaped products provided by the present invention is as follows:

[0022] Place the spool-shaped products according to the preset number of upper and lower layers, the number of front and back rows, and the odd and even column numbers in each row. Starting from the first row, stack them in the order from front to back. Any adjacent front and back rows of spool-shaped products are stacked according to the set steps. The set steps include:

[0023] Step 1: Stack the spool-shaped products layer by layer at the odd column positions in the previous row until the difference between the number of single stacks of spool-shaped products in the odd columns of the previous row and the number of single stacks of spool-shaped products in the even columns of the previous row is equal to 2;

[0024] Step 2: Place one layer of spool-shaped products at the even column positions in the previous row, and judge the difference between the number of single stacks of spool-shaped products at the even column positions in the previous row and the number of single stacks of spool-shaped products at the odd column positions in the next row. When the difference is less than 2, return to the first row and start stacking the spool-shaped products according to Step 1. When the difference is equal to 2, proceed to Step 3;

[0025] The spool-shaped products at the even column positions are horizontally inserted corresponding to the spool-shaped products at the adjacent odd column positions, and the spool-shaped products at the even column positions are stacked and pressed on the spool-shaped products at the adjacent odd column positions to form corresponding tightly stacked units;

[0026] Step 3: Place one layer of spool-shaped products at the odd column positions in the next row, and judge the difference between the number of single stacks of spool-shaped products at the odd column positions in the next row and the number of single stacks of spool-shaped products at the even column positions in the next row. When the difference is less than 2, return to the first row and start stacking the spool-shaped products according to Step 1. When the difference is equal to 2, place one layer of spool-shaped products at the even column positions in the next row, and then return to the first row and start stacking the spool-shaped products according to Step 1;

[0027] When stacking, the spool-shaped products at the even column positions in the next row are horizontally inserted corresponding to the spool-shaped products at the adjacent odd column positions in the next row, and the spool-shaped products at the even column positions in the next row are stacked and pressed on the spool-shaped products at the adjacent odd column positions in the next row to form corresponding tightly stacked units;

[0028] For the closely stacked units in Step 2 and Step 3, among the two stacks of spool-shaped products belonging to the same closely stacked unit, one stack of spool-shaped products are all support parts, and the other stack of spool-shaped products are all press-fitting parts. The two stacks of spool-shaped products are horizontally inserted correspondingly, so that for any vertically adjacent press-fitting part and support part, the corresponding side wheel edges of the upper press-fitting part are stacked and press-fitted on the corresponding side wheel edges of the lower support part.

[0029] The beneficial effect is that in the spool-shaped product stacking method provided by the present invention, the arrangement order of any two adjacent rows is restricted, which can effectively ensure that any vertically adjacent spool-shaped products in a single stack are stacked, and the two adjacent stacks of spool-shaped products in the same row are horizontally inserted correspondingly to form a compact layout, which is convenient for automatic stacking.

[0030] As a further improvement, after the first row is stacked to the set number of layers, the subsequent row is sequentially replaced with a new first row, and the stacking is continued according to the set steps, and so on until all rows are stacked.

[0031] As a further improvement, in Step 3 above, when stacking the spool-shaped products at the odd-numbered column positions of the latter row, the spool-shaped products at the odd-numbered column positions of the latter row are horizontally inserted correspondingly with the spool-shaped products of the previous row, and the spool-shaped products at the odd-numbered column positions of the latter row are stacked and press-fitted on the corresponding spool-shaped products of the previous row.

[0032] The beneficial effect is that when stacking the spool-shaped products at the odd-numbered column positions of the latter row, horizontally inserting them correspondingly with the spool-shaped products of the previous row can reduce the overall floor area and improve the overall structural strength after stacking.

[0033] As a further improvement, the spool-shaped product is a metal basket-type winding disc. Description of the Drawings

[0050] The present invention will be further described in detail below with reference to embodiments.

[0051] Specific Embodiment 1 of the method for palletizing spool-shaped products provided by the present invention:

[0052] This palletizing method is used to palletize metal basket-type winding reels in this embodiment, and its structure is as Figure 1 shown, which will not be elaborated here.

[0053] When implementing the palletizing method in this embodiment, the winding reels are stacked according to the preset number of upper and lower layers, the number of front and rear rows, and the odd and even column numbers of each row. Specifically, the winding reels are stacked in the order from front to back.

[0054] The winding reels in any two adjacent front and rear rows are stacked according to the following set steps:

[0055] Step 1: Stack and place the winding reels layer by layer at the positions of the odd columns in the previous row until the difference between the number of single stacks of winding reels in the odd columns of the previous row and the number of single stacks of winding reels in the even columns of the previous row is equal to 2.

[0056] Step 2: Place a layer of winding reels at the positions of the even columns in the previous row, and judge the difference between the number of single stacks of winding reels at the positions of the even columns in the previous row and the number of single stacks of winding reels at the positions of the odd columns in the next row. When this difference is less than 2, return to the first row and start stacking the winding reels according to Step 1. When this difference is equal to 2, proceed to Step 3.

[0057] The winding reels at the positions of the even columns are horizontally inserted corresponding to the winding reels at the positions of the adjacent odd columns, and the winding reels at the positions of the even columns are stacked and pressed on the winding reels at the positions of the adjacent odd columns to form corresponding tightly stacked units.

[0058] Step 3: Stack a layer of wire spools at the positions of the odd-numbered columns in the next row, and determine the difference between the number of single-stack wire spools at the positions of the odd-numbered columns in the next row and the number of single-stack wire spools at the positions of the even-numbered columns in the next row. When the difference is less than 2, return to the first row and start stacking wire spools according to Step 1. When the difference is equal to 2, stack a layer of wire spools at the positions of the even-numbered columns in the next row, and then return to the first row and start stacking wire spools according to Step 1.

[0059] During stacking, the wire spools at the positions of the odd-numbered columns in the next row are horizontally inserted into the corresponding wire spools in the previous row, and the wire spools at the positions of the odd-numbered columns in the next row are stacked and pressed on the corresponding wire spools in the previous row. The wire spools at the positions of the even-numbered columns in the next row are horizontally inserted into the corresponding wire spools at the positions of the odd-numbered columns on the corresponding side in the next row, and the wire spools at the positions of the even-numbered columns in the next row are stacked and pressed on the corresponding wire spools at the positions of the odd-numbered columns on the corresponding side in the next row to form corresponding tightly stacked units.

[0060] For the tightly stacked units in Step 2 and Step 3, among the two stacks of spool-shaped products belonging to the same tightly stacked unit, one stack of spool-shaped products are all support parts, and the other stack of spool-shaped products are all press-fitting parts. The two stacks of spool-shaped products are horizontally inserted correspondingly, so that for any adjacent upper and lower press-fitting part and support part, the corresponding side wheel edges of the upper press-fitting part are stacked and pressed on the corresponding side wheel edges of the lower support part.

[0061] The following Figures 5 to 7 introduces the specific stacking method. Taking the common 5 rows and 4 columns as an example, the number of layers can be arranged according to actual needs, and the tight stacking method is adopted. Specifically, it can be stacked manually or by using a mechanically controlled palletizing device.

[0062] For the convenience of description, the number of each wire spool is set as A ijm , where i is the row number, j is the column number, and m is the number of layers. The row number, column number, and number of layers all start from 1. The column number j in each row is divided into odd-numbered columns and even-numbered columns, where the odd-numbered columns are the 1st, 3rd, 5th, 7th... items, and the even-numbered columns are the 2nd, 4th, 6th... items. After all stacking is completed, the numbers of the wire spools on the bottom layer, that is, the 1st layer, are as Figure 7 shown.

[0063] When stacking wire spools, first stack a layer of wire spools at the odd-numbered columns in the first row. According to the conditions in Step 1 above, it is necessary to stack another layer of wire spools at the odd-numbered columns. The upper and lower layers of each stack of wire spools are tightly stacked, until the difference between the number of single-stack wire spools at the odd-numbered columns in the first row and the number of single-stack wire spools at the even-numbered columns in the first row is equal to 2. The stacking order is A 111 、A 131 、A 112 、A 132 , stacking layer by layer, as shown in Figure 5 (a).

[0064] At this time, the difference between the number of single-stack winding reels in the odd-numbered columns of the first row and the number of single-stack winding reels in the even-numbered columns of the first row is equal to 2. Start stacking a layer of winding reels at the even-numbered columns of the first row. The winding reels at the even-numbered column positions here are horizontally inserted corresponding to the winding reels at the odd-numbered column positions on the corresponding side, and the winding reels at the even-numbered column positions are stacked and pressed on the winding reels at the odd-numbered column positions on the corresponding side, as shown in Figure 5 (b) of the figure. The stacking order of the first 6 metal basket-type winding reels is A 111 、A 131 、A 112 、A 132 ,A 121 、A 141 。

[0065] It should be noted that during stacking, after stacking a layer of winding reels at the even-numbered columns of the first row, judge the difference between the number of single-stack winding reels in the even-numbered columns of the first row and the number of single-stack winding reels in the odd-numbered columns of the second row. When the difference is less than 2, return to the first row and start stacking the winding reels according to step one. When the difference is equal to 2, perform step three. That is to say, when the difference is equal to 2, start stacking to the next row.

[0066] As shown in Figure 5 (b) of the figure, the number of single-stack winding reels in the odd-numbered columns of the first row is 2, the number of single-stack winding reels in the even-numbered columns of the first row is 1, and the difference is 1. Since this difference is less than 2, return to the first row and start stacking the winding reels again according to the above step one, that is, start stacking the winding reels at the odd-numbered columns of the first row again, as shown in Figure 5 (c) of the figure. The stacking order of the first 8 metal basket-type winding reels is A 111 、A 131 、A 112 、A 132 ,A 121 、A 141 、A 113 、A 133 。At this time, the number of single-stack winding reels in the odd-numbered columns of the first row is 3, the number of single-stack winding reels in the even-numbered columns of the first row is 1, and the difference is equal to 2. Directly perform the second step, that is, immediately stack a layer of winding reels at the even-numbered columns of the first row, as shown in Figure 5 (d) of the figure. That is, the stacking order of the first 10 metal basket-type winding reels is A 111 、A 131 、A 112 、A 132 ,A 121 、A 141 、A 113 、A 133 、A 122 、A 142At this time, the number of single-stack winding reels in the even columns of the first row is 2, while the number of single-stack winding reels in the odd columns of the second row is zero. At this time, it is judged that the difference between the number of single-stack winding reels in the even columns of the first row and the number of single-stack winding reels in the odd columns of the second row is equal to 2, and the stacking starts in the next row, that is, the winding reels start to be stacked in the second row. As Figure 5 shown in (e) of Figure 6 , the stacking order of the first 12 metal basket-type winding reels is A 111 , A 131 , A 112 , A 132 , A 121 , A 141 , A 113 , A 133 , A 122 , A 142 , A 211 , A 231 .

[0067] It should be noted that when stacking the winding reels in the odd columns of the second row, the winding reels at the odd-column positions in the second row are horizontally inserted corresponding to the winding reels in the first row, and the winding reels at the odd-column positions in the second row are stacked and pressed on the corresponding spool-shaped products in the first row to form corresponding tightly stacked units.

[0068] After stacking one layer of winding reels in the odd columns of the second row, judge the difference between the number of single-stack winding reels at the odd-column positions in the second row and the number of single-stack winding reels at the even-column positions in the second row. When the difference is less than 2, return to the first row and start stacking the winding reels according to the steps at the beginning. When the difference is equal to 2, stack one layer of winding reels at the even-column positions in the second row, and then return to the first row and start stacking the winding reels according to the steps at the beginning.

[0069] As Figure 5 shown in (e) of

[0070] At this time, the number of single-stack winding reels at the odd-column positions in the second row is 1, while the number of single-stack winding reels at the even-column positions in the second row is 0, and the corresponding difference is less than 2. At this time, it is necessary to return to the first row and start stacking the winding reels again according to the steps at the beginning.

[0071] And, after stacking the first row to the set number of layers, sequentially replace the subsequent row with a new first row and continue stacking according to the above-set steps, and so on, continuously repeating in a cycle until the stacking is completed. Among them, the arrangement method of the winding reels at the bottom layer is as Figure 7 shown.

[0072] It should be noted that during the stacking process, the winding reels in any stack are stacked closely together in pairs. As Figure 3 shown, there will be no situation of cross-stacking as Figure 2 shown.

[0073] In the stacking method provided in this embodiment, in order to minimize the space occupied by the stacking of winding reels as much as possible, among any adjacent front and back rows of winding reels, the winding reels at the odd-numbered column positions in the latter row should be horizontally inserted into the winding reels in the previous row. Of course, in other embodiments, the winding reels at the odd-numbered column positions in the latter row can also be separated from the winding reels in the previous row, and the two are not connected.

[0074] Embodiment of the palletizing structure of the spool-shaped product provided by the present invention:

[0075] The winding reels can be stacked according to the above stacking method to form a stacking structure as Figure 3 and Figure 4 . Taking three stacks of winding reels as an example to introduce the stacking structure, the three stacks of winding reels are the left winding reel 300, the right winding reel 301, and the rear winding reel 302. In any stack of spool-shaped products, any adjacent upper and lower layers of winding reels are stacked closely and flush with each other.

[0076] The above three stacks of winding reels are arranged in two rows in sequence along the front and back directions. Two stacks are arranged in the first row and one stack is arranged in the second row.

[0077] Moreover, the above three stacks of winding reels form two sets of closely stacked units, that is, the left winding reel 300 and the right winding reel 301 form a set of closely stacked units, and the right winding reel 301 and the rear winding reel 302 form a set of closely stacked units. For any set of closely stacked units, the corresponding two stacks of winding reels are horizontally inserted into each other. One stack of winding reels is the supporting winding reel, and the other stack of winding reels is the pressing winding reel. Among any adjacent upper and lower pressing winding reels and supporting winding reels, the corresponding side wheel edges of the pressing winding reel are stacked and pressed on the corresponding side wheel edges of the supporting winding reel.

[0078] In this stacking structure, all the winding reels in any stack are stacked and arranged to form a closely stacked and placed manner of AABB, without interposing the winding reels of other stacks in the middle. The adjacent two stacks of winding reels are inserted and stacked together, and the inclination angle of each stack of winding reels is always the same, and there will be no problem of layer-by-layer accumulation. Compared with the staggered stacking arrangement in the prior art, the number of layers of the same type of winding reels stacked will be relatively higher.

[0079] In this embodiment, only three stacks of wire reels are stacked. Two stacks are placed in the first row and one stack is placed in the second row. In other embodiments, four stacks can also be placed in the first row, distributed in odd and even columns, and three stacks are placed in the second row. The four stacks of wire reels in the same row are grouped in pairs adjacent to each other in sequence to form three closely stacked units, and they can be arranged in an alternating pattern of support wire reel - press - fit wire reel - support wire reel - press - fit wire reel. That is, the first stack of wire reels are all support wire reels, the second stack of wire reels are all press - fit wire reels, the third stack of wire reels are all support wire reels, and the fourth stack of wire reels are all press - fit wire reels. This can make the side rims of the second stack of wire reels be press - fitted corresponding to the side rims of the first stack and the third stack of wire reels, and the corresponding side rims of the fourth stack of wire reels be press - fitted corresponding to the side rims of the third stack of wire reels. At this time, according to the above - mentioned stacking method, the first stack and the third stack are horizontally arranged, the second stack is also horizontally arranged, and the fourth stack is inclined. However, since the inclination angles of each layer are parallel and consistent, there will be no cumulative problem.

[0080] Of course, in other embodiments, three stacks of wire reels can also be arranged in a single row, or more than five stacks of wire reels. The wire reels of more than three stacks can be arranged in an alternating pattern of support wire reel - press - fit wire reel - support wire reel, or in an alternating pattern of press - fit wire reel - support wire reel - press - fit wire reel.

[0081] In the above - mentioned embodiment of three stacks of wire reels, only two rows are arranged. In other embodiments, multiple rows can also be arranged in sequence in the front - to - back direction. The three stacks of wire reels in each row are arranged in the pattern of odd - numbered column - even - numbered column - odd - numbered column. The wire reels in the odd - numbered columns of each row are all support wire reels, and the wire reels in the even - numbered columns of each row are all press - fit wire reels, so that at least three stacks of wire reels in the same row are arranged in an alternating pattern of support wire reel - press - fit wire reel - support wire reel. Moreover, in any two adjacent rows of wire reels in the front - to - back direction, the rim of any single stack of wire reels in the odd - numbered column of the rear - row wire reels is correspondingly stacked and press - fitted on the rim of a stack of wire reels in the front - row wire reels to form a corresponding closely stacked unit. Of course, in other embodiments, if the horizontal stacking space is large enough, the wire reels in any two adjacent rows in the front - to - back direction can also be adjacently arranged, and the wire reels in the front - to - back rows are not inserted.

[0082] It should be noted that if multiple rows are arranged in the front - to - back direction, and for any two adjacent rows in the front - to - back direction, when the rear - row wire reels are horizontally inserted into the front - row wire reels, the rear - row wire reels will be inclined. In this way, the wire reels successively backward will all be inclined in sequence.

[0083] In the embodiments provided by the present invention, both the stacking structure and the stacking method are used for stacking wire reels. Of course, they can also be applied to other spool-shaped products. At this time, for the stacking equipment, different execution manipulator structures can be replaced according to the actual products to be stacked. Other spool-shaped products include, for example, wire reels with an annular plate structure at the wheel edge.

[0084] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
