本发明涉及一种侧压式竹集成材无限长层板的机械组坯装置,具体涉及一种使用阶梯推送机构和横向拨料机构的侧压式竹集成材无限长层板的机械组坯装置,本装置结构简单、高效,适合于生产侧压式竹集成材无限长层板的热压生产线的组坯工段使用。The invention relates to a mechanical blank assembly device of a side-pressed bamboo lamella infinite-length laminate, in particular to a mechanical blank-assembly device of a side-pressed bamboo laminate infinite-length laminate using a step pushing mechanism and a lateral pulling mechanism The device has a simple and high-efficiency structure, and is suitable for use in the blank assembly section of a hot-pressing production line for producing infinite-length side-pressed bamboo laminates.
背景技术Background technique
竹集成材是由长条竹片(横截面一般为矩形,长度一般为1 m-2.5 m,宽度(或高度)约为20mm,厚度约为6mm)胶合而成的型材(板材或方材)。其中,薄的竹集成材仅由一层竹片侧面胶拼而成;而厚的竹集成材则由多层经侧面胶拼而成的竹层板正面胶合而成。因此,竹集成材层板(简称竹层板)即为由一层长条竹片侧面胶合而成的竹拼板。矩形长条竹片的窄面(厚度)和宽面(宽度)均可作为胶合面,其中以竹片宽面为胶合面的竹层板厚度较大,且胶合强度和力学性能更好,可作为结构用竹集成材的层板使用。由于生产竹集成材层板的热压机的热压板为水平放置,故竹片的胶合面处于铅垂面,对于以宽面为胶合面的矩形竹片则为竖立状态;该竹层板的胶合面处于热压机的侧面,即该竹层板的胶合主压力方向在热压机的侧面,如此生产出来的竹层板被称为侧压式竹集成材层板。Bamboo glulam is a profile (plate or square) that is glued by long bamboo sheets (generally rectangular in cross section, 1 m-2.5 m in length, about 20 mm in width (or height) and about 6 mm in thickness) . Among them, the thin bamboo lamella is only made up of one layer of bamboo slices glued on the side; while the thick bamboo lamella is made of multiple layers of bamboo laminates glued on the sides and glued together on the front. Therefore, bamboo glulam laminates (bamboo laminates for short) are bamboo jigsaw panels formed by gluing a layer of long bamboo slices on the sides. The narrow side (thickness) and wide side (width) of the rectangular bamboo strips can be used as the glued surface. The bamboo laminate with the wide surface of the bamboo slices as the glued surface is thicker, and has better bonding strength and mechanical properties. It is used as a laminate of bamboo glulam for structure. Since the hot-pressing plate of the hot-pressing machine for producing bamboo lamella laminates is placed horizontally, the gluing surface of the bamboo sheet is in the vertical plane, and the rectangular bamboo sheet with the wide side as the gluing surface is in an upright state; the bamboo laminate is in a vertical state. The gluing surface is on the side of the hot press, that is, the main gluing pressure direction of the bamboo laminate is on the side of the hot press. The bamboo laminate produced in this way is called a side-pressed bamboo laminate.
目前,公知的侧压式竹集成材层板(其单元竹片为侧立状态)的组坯基本上仍采用手工作业。CN109093789A “一种侧压式竹集成材层板的机械组坯装置” 的发明专利解决了由通长规格竹片进行竹层板机械组坯的难题,但若生产较长或无限长竹层板,因规格竹片长度有限,需要接长(且相邻竹片的接头需错开一定的距离)。但是竹片长易弯曲,对接时容易错位,不易对中,因此无限长竹层板的组坯难以实现机械自动化。目前,无限长竹层板的组坯全部依靠手工操作。由于竹片薄,数量很多,且涂有胶黏剂,手工组坯很不方便,既脏又累,效率很低。At present, the assembling of the known side-pressed bamboo lamella laminates (the unit bamboo sheets of which are in a side-standing state) is basically still done by hand. CN109093789A The invention patent of "a side-pressing type bamboo laminated board mechanical blanking device" solves the problem of mechanical blanking of bamboo laminates from bamboo sheets of normal length, but if the production of long or infinite bamboo laminates , Due to the limited length of the bamboo pieces, it needs to be lengthened (and the joints of the adjacent bamboo pieces need to be staggered by a certain distance). However, the bamboo sheets are long and easy to bend, and they are easy to be dislocated and difficult to be aligned when docking. Therefore, it is difficult to realize mechanical automation of the assembly of infinitely long bamboo laminates. At present, the assembly of infinitely long bamboo laminates all rely on manual operations. Due to the thinness of the bamboo pieces, the large number of them, and the coating of adhesives, it is very inconvenient to manually assemble the blanks, which are dirty and tiring, and the efficiency is very low.
侧立规格竹片易弯曲,容易错位,难以对中接长,但若能控制竹片自由端的位置,保证其不越位,则可使后面的规格竹片顺利实现移动和对接。如果一种装置,能控制长条规格竹片自由端的位置,使后面的竹片能顺利进入,则侧压式竹集成材无限长层板的组坯可以实现机械化,从而减轻劳动强度,提高工作效率,必将受到侧压式竹集成材生产厂家的欢迎。The side-standing bamboo pieces are easy to bend and dislocate, and it is difficult to be centered and lengthened. However, if the position of the free end of the bamboo pieces can be controlled to ensure that they are not offside, the following specification bamboo pieces can be moved and connected smoothly. If there is a device that can control the position of the free end of the long-sized bamboo pieces, so that the back bamboo pieces can enter smoothly, the assembly of the infinite-length laminates of the side-pressed bamboo glulam can be mechanized, thereby reducing the labor intensity and improving the work efficiency. Efficiency, will be welcomed by side-pressed bamboo glulam manufacturers.
