Description

Technical Field

[0001] The utility model relates to the technical field of multi-specification packaging and palletizing of slender bars of longer specifications, in particular to a mobile roller palletizer capable of changing the length and palletizing specifications. Background Art

[0002] Palletizers are essential equipment in straight seam welded pipe production lines. Their primary function is to neatly stack processed straight seam steel pipes into square or hexagonal bundles. While existing palletizer technology is relatively mature, typical palletizers are tailored to one or a few specifications or designed to match them within a certain range. For example, when length specifications vary, a multi-puller stacking structure is employed. This is a relatively outdated approach. The operating principle is to set up multiple pulsators in parallel within the working length range of the slender bars to accommodate the different lengths of the bars. To ensure proper palletizing within the customer's required length specifications, a large number of these pulsators are required, and as a result, a large number of pulsators must be moved synchronously during operation. Consequently, when stacking shorter slender bars, many pulsators remain idle while still operating, resulting in a certain amount of energy waste. In addition, if the length specifications of one or several slender bars are temporarily increased, there may be a problem that the original set position of the roller cannot match it, which will affect the performance of the entire production line. In order to solve this problem, technical personnel in this field have developed a mobile roller palletizer that saves costs and can easily and conveniently realize multi-specification palletizing, which has become an industry trend. Utility Model Content

[0003] This utility model aims to overcome the shortcomings and deficiencies of the aforementioned technologies by adding a slide beam structure to replace a fixed palletizer with a mobile one. By varying the spacing between palletizers, the palletizer can accommodate the palletizing of slender bars of various lengths. This technical solution offers a simple structure, ease of repair and maintenance, a wide range of applications, cost savings, and improved precision and efficiency.

[0004] Specifically, the purpose of the present invention is achieved by adopting the following technical solutions: on the one hand, a mobile roller stacker is provided for stacking slender bars b of various specifications, and is provided with a gantry frame j and at least one mobile vehicle y. The slender bars b are input into the gantry frame j through a conveying device. The mobile vehicle y is slidably installed with the gantry frame j through a longitudinal slide rail zg and can slide linearly on the gantry frame j perpendicular to the input direction of the slender bars b. A slide rail beam hg is also suspended below the mobile vehicle y, and the at least one mobile roller yc is suspended and slidably installed below the slide rail beam hg. The length extension direction of the slide rail beam hg is the same as the input direction of the slender bars b. The multiple mobile rollers yc can adjust the distance between each other by sliding along the length direction of the slide rail beam hg to realize the suspension and stacking of slender bars b of various length specifications.

[0005] According to one aspect of the specific implementation of the embodiment of the utility model, the mobile rub yc is provided with a driving wheel zzd to drive it to slide freely on the slide rail beam hg.

[0006] According to one aspect of the specific implementation of the embodiment of the present utility model, three movable rubs yc are provided on the slide rail beam hg, and are arranged equidistantly from each other through program setting to suspend the two ends and the center of the slender bar b respectively.

[0017] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified, “perpendicular” and “parallel” do not just have absolute meanings in a mathematical sense, but can be understood as “approximately perpendicular” and “approximately parallel”.

[0018] Figure 1 It is a schematic diagram of the overall layout of the basic structure of an embodiment of the present utility model.

[0019] like Figure 1 As shown, the present invention aims to avoid the shortcomings and deficiencies existing in the above-mentioned technologies by adding a slide rail beam to realize the conversion of fixed stacking rubs into mobile stacking rubs, and adapt to the stacking work of slender bars of various length specifications by changing the spacing between the stacking rubs. The technical solution has a simple structure, is easy to repair and maintain, has a wide range of applications, saves costs, and improves precision and efficiency. In a specific embodiment, the purpose of the present invention is achieved by adopting the following technical solution, which is provided with a gantry frame j and at least one mobile vehicle y in a specific structure. The gantry frame j is fixed to the ground by two groups of front and rear columns, and the columns are connected to each other by steel structure beams. A longitudinal beam is also provided between the two groups of steel structure beams, and a longitudinal slide rail zg is also provided on the longitudinal beam. The mobile vehicle y is slidably installed with the gantry frame j through the longitudinal slide rail zg. The slender bar b is input into the gantry frame j through a conveying device. The mobile car y is also provided with a power device that can provide it with power to drive it to move freely on the longitudinal slide rail zg, and can slide linearly on the gantry frame j perpendicular to the input direction of the slender bar b. The mobile car y is also provided with a suspension rod and a suspension rod driver. The suspension rod is vertically mounted on the mobile car y and can be moved up and down by the drive of the suspension rod driver. In this embodiment, two groups of mobile cars y are preferably provided. The two groups of mobile cars y are evenly distributed above the gantry frame j. Two suspension rods extend downward from the two groups of mobile cars y. A slide rail beam hg is also fixed below the two suspension rods. The two suspension rods move up and down synchronously under the action of the suspension rod driver to enable the slide rail beam hg to move up and down. When the mobile car y moves longitudinally on the longitudinal slide rail zg, it can also drive the slide rail beam hg to move longitudinally synchronously.

[0022] like Figure 2 and Figure 3 As shown, according to one aspect of the specific implementation of the embodiment of the utility model, the at least one mobile yc is suspended and slidably installed below the slide rail beam hg. In this embodiment, three mobile ycs are preferably provided and slidably installed with the slide rail beam hg through a sliding wheel structure. The mobile yc is configured as a suspension device with a magnetic device below for magnetically suspending a slender metal bar. The mobile yc is provided with a driving wheel zzd and a driven wheel to drive it to slide freely on the slide rail beam hg. The length extension direction of the slide rail beam hg is the same as the input direction of the slender bar b. The multiple mobile ycs can adjust the spacing between each other by sliding along the length direction of the slide rail beam hg to achieve the suspension and stacking of slender bars b of various length specifications, and are arranged equidistantly from each other through program setting to suspend the two ends and the center of the slender bar b respectively, so as to achieve uniform force on the slender bar b to prevent its deformation.

[0026] Figure 6 It is a schematic diagram of another picking method of an embodiment of the present utility model.

[0027] like Figure 6As shown, according to one aspect of the specific implementation of another embodiment of the utility model, only one or two of the mobile rubbers yc can be used to stack the shorter slender bars b. When the minimum span composed of the three mobile rubbers yc is greater than the maximum length of the slender bars b, one of the mobile rubbers yc on both sides can be selected and left idle, and the other two mobile rubbers yc are started and moved until the maximum span composed can meet the stacking work of the shorter slender bars b, and then stop moving, and the mobile car y can be started to start the stacking work.
