【摘要】：取袋装置是一种用于预制袋包装机上的简单机械装置，其一般用于诸如卧式袋装机、直线立式袋装机以及回转立式袋装机的取袋给袋。目前的取袋技术主要是通过取袋机构带动真空吸盘做往复摆动或直线运动将袋子从袋库中取出放到下一工位再原路返回到取袋工位的方式，这样的取袋装置一般速度低下，当袋装机的装袋速度有进一步提高时，现有的取袋装置就不再适用。因此，需要改变现有的往复取袋的取袋形式，设计可以在一款连续高速条件下工作的取袋装置。论文的研究内容如下： (1)对现有的预制袋的类型结构以及使用的场合进行了分析，确定了可以用于预制袋包装机的各种预制袋的类型；从供送速度、供送方式等角度对现有的各种片材供送装置进行了分析，依次说明了这些片材供送的工艺方法对复合预制袋的适应性；从预制袋的挺度以及自身尺寸的角度进行分析，确定了可以用于连续高速取袋系统的预制袋必须满足的条件。 (2)确定了取袋真空吸盘可能的运动轨迹并从中选择了最适合于连续高速取袋系统的运动轨迹；基于确定的运动轨迹结合取袋吸盘取袋送袋与各种类型包装机，得到吸盘在取袋和放袋位置的局部轨迹；确定轨迹的类型，进一步得到两种形成此轨迹的机构，并从中选择更合适的机构；对得到的运动机构进行结构参数优化，进一步对其进行了运动仿真分析；讨论了系统的取袋能力。 (3)对真空吸盘取袋的基本技术进行了分析，其中包括真空吸盘的类型以及选择、吸盘吸取物品的基本静力学以及动力学分析、真空取袋头袋库取袋受力分析；针对不同规格的袋子，，进行了真空取袋头的设计；对真空分配的工艺方案进行了讨论，得到三种可行的真空分配方式并陈述了各自的优缺点。 (4)针对一种分气工艺对虚拟样机进行设计，对真空吸盘在袋库的局部细节运动进行了模拟分析，进一步确定取袋头与取代时间的关系；分析真空气道、真空气管以及真空吸盘形成额定真空所需要的时间，将以上两者进行比较，已验证在确定的取袋头数的情况下，装置能否达到所需的速度。
[Abstract]:The bag picking device is a simple mechanical device used for the prefabricated bag packing machine, which is usually used in the bag feeding bag such as the horizontal bag machine, the vertical vertical bag machine and the rotary vertical bag machine. When the next station and the original way return to the bag taking work position, this kind of bag picking device is generally low. When the bag loading speed of the bag is further improved, the existing bag picking device is no longer applicable. Therefore, it is necessary to change the existing bag taking form and design the bag for working in a continuous and high speed condition. The research contents of the thesis are as follows:
(1) the type structure of the existing prefabricated bags and the situation of the use are analyzed, and the types of prefabricated bags that can be used for prefabricated bag packaging machines are determined. From the angle of feeding speed and supply way, the existing various sheet feeding devices are analyzed, and the process methods of these sheets are explained in turn to the composite prefabrication. The adaptability of the bag is analyzed from the stiffness of the prefabricated bag and the angle of its own size to determine the conditions that the prefabricated bags that can be used in the continuous high speed bag taking system must be satisfied.
(2) the possible trajectory of the bag vacuum suction cup is determined and the motion trajectory is selected most suitable for the continuous high-speed bag taking system. Based on the determined trajectory, the bag suction bag and various types of packaging machines are combined to obtain the local trajectory of the suction disc in the position of the bag and the bag, and the type of the trajectory is determined to get two further. The mechanism of this trajectory is formed, and the more suitable mechanism is selected from it. The structure parameters of the moving mechanism are optimized, and the motion simulation analysis is carried out to the system, and the bag taking ability of the system is discussed.
(3) the basic technology of vacuum sucker bag taking is analyzed, including the type and selection of vacuum sucker, the basic statics and dynamics analysis of the sucker sucker, the force analysis of the bag collecting bag in the vacuum bag head bag; the design of the true empty bag head is carried out for the bags of different specifications; the process scheme for the vacuum distribution is introduced. After discussion, three feasible ways of vacuum allocation are obtained, and their advantages and disadvantages are stated.
(4) aiming at the design of a virtual prototype for a gas separation process, the local detail movement of the vacuum sucker in the bag reservoir is simulated and analyzed, and the relationship between the bag head and the replacement time is further determined. The time needed for the vacuum inlet, the vacuum trachea and the vacuum sucker to form the rated vacuum is analyzed, and the above two are compared. If the number of bags is determined, can the device reach the required speed?
