管状材料包装的管状材料拉动装置  Tubular material pulling device for tubular material packaging

管状材料包装的管状材料拉动装置 Tubular material pulling device for tubular material packaging

技术领域: Technical field:

本发明涉及 枕式 包装机械,特别涉及一种管状材料的 包装方法 。 The present invention relates to a pillow packaging machine, and more particularly to a method of packaging a tubular material.

背景技术: Background technique:

现有的枕式包装方法是先将片状的包装材料,从纵向将左右的两个边封合起来形成一个腔体,同时将要包装的物品放在腔体中,然后在要包装的物品的两端将腔体封合切断,因为包装好以后状如枕头故名枕式包装。整个包装过程具有自动化程度高,速度快,适用于块状、粒状、粉状、液状的物体,如饼干、蛋黄派、巧克力、面包、方便面、月饼、豆浆、牛奶、酱油、料酒、藕粉等食品,以及各种日用品、各种工业零件、各种医疗器械等各类物体的包装,围绕 枕式包装机已经产生了很多的专利和专门技术。 The existing method of pillow packaging is to first seal the sheet-like packaging material from the longitudinal direction to form a cavity, and place the article to be packaged in the cavity, and then in the article to be packaged. The ends are sealed and cut off at the ends, because the pillows are packed like pillows after being packaged. The whole packaging process is highly automated and fast, suitable for block, granular, powdery, liquid objects, such as biscuits, egg yolk pie, chocolate, bread, instant noodles, moon cakes, soy milk, milk, soy sauce, cooking wine, lotus root starch and other foods. And packaging of various objects such as various daily necessities, various industrial parts, and various medical devices. Pillow packaging machines have produced a lot of patents and expertise.

这种边将片状材料封合成为腔状结构,边将要包装的物品放入腔内进行包装,是一个理想的枕式包装的形式,可是,该形式的包装也就拌生了下列的缺点:1.费料,现有枕式包装机是将片状的包装材料的左右两边缝合后包装的,缝合部分要浪费相当多的包装材料。2.影响美观,缝合后的缝叠留在包装的外面影响包装的美观。3. 该形式的工艺,要求包装材料是多层复合的材料,多层复合的材料价格昂贵。4.相对管状材料的枕式包装而言,增加了一道工序、增加了劳动成本。 The side is sealed into a cavity-like structure, and the packaged article is placed in the cavity for packaging, which is an ideal form of pillow packaging. However, the packaging of the form also has the following disadvantages. : 1. In the case of the material, the existing pillow packaging machine is to wrap the left and right sides of the sheet-like packaging material, and the sewing part wastes a considerable amount of packaging materials. 2. The effect is beautiful, and the seams after stitching remain on the outside of the package to affect the aesthetics of the package. 3. This form of process requires that the packaging material be a multi-layer composite material, and the multilayer composite material is expensive. 4. Compared with the pillow packaging of the tubular material, a process is added and the labor cost is increased.

与上述片状材料的包装工艺相比,用管状材料进行包装的工艺,没有多层复合的材料要求,没有中间的缝合部分,具有省料、美观、节能、价廉的优点。 Compared with the packaging process of the above-mentioned sheet material, the process of packaging with a tubular material has no multi-layer composite material requirements, and has no intermediate stitching portion, and has the advantages of material saving, beautiful appearance, energy saving, and low cost.

可是,管状的包装形式与片状的包装形式相比有很大的不同,片状的包装形式的包装材料可以不停地向前移动,而管状的包装形式的包装材料在没有完成前面一个包装的时候是不向前移动的,在前一个包装完成以后,又必须马上把管状包装材料向前移动,要使开口端准确地输送到出料口。片状的包装材料只要移动一个就能够满足包装速度的要求,而管状的包装形式,需要同时移动4个以上的包装材料才能满足包装的速度要求。 However, the tubular packaging form is quite different from the sheet-like packaging form. The packaging material in the form of a sheet can be moved forward continuously, while the packaging material in the form of a tubular packaging does not complete the previous packaging. When it is not moving forward, after the previous packaging is completed, the tubular packaging material must be moved forward immediately, so that the open end is accurately conveyed to the discharge opening. The sheet-like packaging material can meet the packaging speed requirement by moving one, and the tubular packaging form needs to move more than 4 packaging materials at the same time to meet the packaging speed requirement.

中国专利200820162608一次性注射器的自动包装机的包装袋撑口装置,其拉管的方法是将管状材料吸附在一个旋转的物件上,管状材料随着物件的旋转向上移动,其问题是如何在高速运行的时候确保管状材料准确的移动没有信服的说明。同时,吸附的装置必须始终的运行,必然要耗费不少的能源。 China Patent 200820162608 Disposable syringe automatic packaging machine bag expansion device, the method of pulling the tube is to adsorb the tubular material on a rotating object, the tubular material moves upward with the rotation of the object, the problem is how at high speed There is no convincing explanation for the accurate movement of the tubular material during operation. At the same time, the adsorption device must always operate, which inevitably consumes a lot of energy.

发明内容: Summary of the invention:

本发明的目的:提供一种 同时 将多个 管状材料的开口端保持撑开的状态,准确地向上移动 到出料口的下方 的 管状材料包装的管状材料拉动装置 。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a state in which the open ends of a plurality of tubular materials are simultaneously opened and accurately moved up to the lower side of the discharge opening.

具体实施方式: detailed description:

参照 附图1, 实践例初始状态时的局部放大的 侧视剖面示意图。 Referring to Figure 1, a partially enlarged side cross-sectional view of the initial state of the practice example.

因为侧视的关系,图中只显示一个管状材料 的初始状态 的图形。 Because of the side view, only a graph of the initial state of the tubular material is shown.

图中显示: 卷成圈状的管状材料51在内撑坑11的下面,每个管状材料50的开口端52在内撑坑11的上面,内撑20在管状材料50的开口端52内,内撑20放在内撑坑11上。 The figure shows: The rolled tubular material 51 is under the inner struts 11, the open end 52 of each tubular material 50 is above the inner struts 11, the inner struts 20 are in the open end 52 of the tubular material 50, and the inner struts 20 are placed. On the inner struts 11.

内撑坑11是一列纵队的形式设置在内撑座10上,内撑坑11的口向上,内撑坑11在出料口60的正下方。 The inner struts 11 are arranged in the form of a column of columns on the inner support 10, the mouth of the inner struts 11 is upward, and the inner struts 11 are directly below the discharge opening 60.

拉管器30由夹具31和升降器33组成,夹具31上有若干个夹件32,夹具31上夹件32的数量以及位置与内撑坑11的数量以及位置相同。 The puller 30 is composed of a clamp 31 and a lifter 33. The clamp 31 has a plurality of clamp members 32. The number and position of the clamp members 32 on the clamp 31 are the same as the number and position of the inner support pits 11.

夹具31是水平方向张开和闭合,夹具31张开或闭合的时候所有的夹件32同时动作。 The jig 31 is opened and closed in the horizontal direction, and all the clips 32 are simultaneously operated when the jig 31 is opened or closed.

图中,张开状态的夹具31在所有内撑坑11的两旁,也就是在所有内撑20的两旁。 In the figure, the clamp 31 in the open state is on both sides of all the inner struts 11, that is, on both sides of all the inner struts 20.

夹具31与升降器33连接,夹具31可以升降,夹具31在内撑座10的上方和出料口60的下方之间沿着导轨34上下移动。 The jig 31 is connected to the lifter 33, and the jig 31 can be raised and lowered. The jig 31 moves up and down along the guide rail 34 between the upper support 10 and the lower side of the discharge port 60.

高度检测器40与升降器33连接,高度检测器40在夹具31到达设定的高度以后发送高度信息,在高度检测器40发送高度信息以后,升降器33停止移动。 The height detector 40 is connected to the lifter 33, and the height detector 40 transmits the height information after the clamp 31 reaches the set height, and after the height detector 40 transmits the height information, the lifter 33 stops moving.

参照 附图2,附图2是 实践例的初始状态时俯 视示意图。 Referring to Figure 2, Figure 2 is a schematic plan view of the initial state of the practical example.

图中显示的是并排排列的5个夹件32和5个 内撑坑11 , 它们排成一列纵队, 构成5个包装单元,该包装单元的个数仅表示本发明实施例的包装单元可以是多个的,其它实施例可以大于或小于5个包装单元。 Shown are five clips 32 and five inner struts 11 arranged side by side, which are arranged in a column. The five packaging units are formed. The number of the packaging units only indicates that the packaging unit of the embodiment of the present invention may be plural, and other embodiments may be larger or smaller than five packaging units.

夹件32的数量以及位置与内撑坑11的数量以及位置相同,就是一个夹件32在一个内撑坑11的两旁,因为一个内撑20在一个内撑坑11的里面,也就是一个夹件32在一个内撑20的两旁。 The number and position of the clips 32 are the same as the number and position of the inner struts 11, that is, one clip 32 is on both sides of an inner struts 11, because one inner struts 20 are inside the inner struts 11, that is, a clip. The piece 32 is on either side of an inner support 20.

所以,在夹具31闭合的时候,所有的夹件32可以同时闭合夹住了所有的内撑20。因为所有的内撑20都在管状材料50的开口端52内,夹住了内撑20也意味着就是夹住了开口端52。 Therefore, when the clamp 31 is closed, all of the clamp members 32 can simultaneously close and clamp all of the inner supports 20. Since all of the inner struts 20 are within the open end 52 of the tubular material 50, clamping the inner struts 20 also means gripping the open end 52.

参照 附图3,附图3是 装置运行的第1步,夹具31开始闭合,准备夹持住开口端52的示意图 。 Referring to Figure 3, Figure 3 is a first step of the operation of the apparatus with the clamp 31 beginning to close, ready to grip the open end 52.

夹具31按箭头指示的方向向内闭合,将所有的在开口端52内的内撑20夹住。因为开口端52在夹件32和内撑20的中间,夹件32夹住了内撑20,也意味着夹住了开口端52。 The clamp 31 is closed inwardly in the direction indicated by the arrow, clamping all of the inner struts 20 in the open end 52. Since the open end 52 is intermediate the clip 32 and the inner stay 20, the clip 32 clamps the inner stay 20, which also means that the open end 52 is clamped.

参照 附图4,附图4是 装置运行的第2步,夹具31开始沿着导轨34向上移动的示意图 。 Referring to Figure 4, Figure 4 is a schematic illustration of the second step of operation of the apparatus with the clamp 31 beginning to move up the rail 34.

夹具31向内闭合以后,夹住了所有的内撑坑11上的内撑20开始向上移动,在夹具31向上移动的时候,因为开口端52向上移动,管状材料50也同时向上拉动。 After the clamp 31 is closed inwardly, the inner stay 20 sandwiching all of the inner struts 11 starts to move upward, and as the clamp 31 moves upward, the tubular material 50 is simultaneously pulled upward because the open end 52 moves upward.

高度检测器40在管状材料50移动的时候,对管状材料50上的标识53进行检测, 在高度检测器40检测到标识53的时候发送高度信息,升降器33停止移动。 The height detector 40 detects the indicia 53 on the tubular material 50 as the tubular material 50 moves. When the height detector 40 detects the marker 53, the height information is transmitted, and the lifter 33 stops moving.

从上述实践例可以看到管状材料50的拉动,是在开口端52张开的情况下进行的,管状材料50的拉动速度和精确度完全是可以控制的。 It can be seen from the above-described practical examples that the pulling of the tubular material 50 is carried out with the open end 52 open, and the pulling speed and accuracy of the tubular material 50 are completely controllable.
