用于由薄片包装材料制成的管生产密封包装的成形设备技术领域本发明涉及一种由一个填充可倒出的食品的薄片包装材料制成的管生产密封包装的成形设备。 Technical field produced by the tube of packaging sheet material sealed package forming apparatus of the present invention relates to the production of a tube filled by a pourable food product made of sheet packaging material sealed package forming apparatus. 背景技术如所知的，许多可倒出的食品都是被放入包装中出售，包装由消过毒的薄片包装材料制成，这些食品例如是果汁、巴氏杀菌牛奶或UHT(超高温处理）牛奶、葡萄酒、番茄酱等等。 As is known, many pourable foods are being sold into the packaging, the packaging from sterile sheet packaging material, these foods such as fruit juice, pasteurized milk or UHT (ultra high temperature treatment ) milk, wine, tomato sauce, and so on. 这种包装的一个典型例子是用于液体或通称为Tetra Brik Aseptic (注册的商标）的可倒出食品的平行六面体形的包装，该包装通过折叠或密封一个层压的包装材料幅板（或幅面料）而形成。 A typical example of this type of package is a known as a liquid or Tetra Brik Aseptic (registered trademark) of pourable food products parallelepiped-shaped package, the package by folding or sealing of a laminated packaging material webs (or pieces of fabric) is formed. 包装材料具有多层结构，该结构包括一层纸材料，该纸材料两側用热封塑性材料层覆盖，例如聚乙烯；和，就用于长期储存产品例如UHT 牛奶的无菌包装来说，包装材料还包括一层例如由一个铝片确定的氧阻隔材料，该氧阻隔材料叠置在热封塑性材料层上，并且又用另一层热封塑性材料覆盖，该层热封塑性材料最终确定了包装与食品接触的内表面。 The packaging material has a multilayer structure, the structure comprising a layer of paper material, the paper material covered on both sides with a layer of heat-seal plastic material,
and on for long-storage products, such as UHT milk, aseptic packages, the the packaging material also comprises a layer of oxygen-barrier material such as an aluminum sheet determined by the oxygen barrier material superposed on the layer of heat-seal plastic material, and in turn covered with another layer of heat-seal plastic material, the final layer of heat-seal plastic material determine the inner surface of the packaging in contact with food. 如已知的，这种包装在全自动包装机上形成，在包装机上，连续的管由供给的包装材料幅板形成。 As is known, such packages are formed in the automatic packaging machine, the packaging machine, the continuous tube is formed from the web-fed packaging material sheet. 更具体地，包装材料幅板从一个巻筒上退绕并通过包装机上的一个无菌室，在该无菌室中例如通过应用一种化学消毒剂进行消毒，譬如过氧化氬，稍后通过加热和/或使包装材料经受合适波长和强度的辐射而使该消毒剂蒸发；经如此消毒的幅板被保持在封闭的无菌环境中，并以公知的方式纵向折叠和密封成圆柱形以形成一个连续的管。 More specifically, the web of packaging material is unwound from the plate cylinder of a cluttered with coils and passed through a sterile chamber on the packaging machine, in which the sterile chamber, for example, sterilized by applying a chemical sterilizing agent, such as peroxide argon later by heating and / or subjecting the packaging material to radiation of appropriate wavelength and intensity of the disinfectant wa sterilized by the web plate is thus maintained in a closed sterile environment, and in a known manner is folded and sealed longitudinally to a cylindrical shape form a continuous tube. 包装材料的管在垂直方向上被连续供给，填充消过毒的或经过无菌处理的食品，并且通过一个用来形成单独包装的成形设备，该包装材料的管换句话说形成了无菌室的延伸。 The tube of packaging material is fed continuously in a vertical direction, is filled or sterilized through aseptic processing of foods, and to form a single package through a forming apparatus used, the tube of packaging material to form a sterile chamber in other words extension. 成形设备包括两对在包装材料的管上循环和连续地起作用的夹持件，以沿着等距的横截面夹持和热封该包装材料的管，因而通过相应的橫向密封带形成彼此相连的连续的枕状包装带，横向密封带即垂直于管 Forming apparatus comprises two circulating in the tube of packaging material and the continuously acting clamping members, equally spaced along the cross-section of the clamping and heat sealing the packaging material tube, which through respective transverse sealing bands with each other pillow-shaped packaging with a continuous connected, i.e., the transverse sealing band perpendicular to the tube
的行进方向延伸的密封带。 Extending in the direction of travel of the sealing tape. 通过切断相关的横向密封带使枕状包装分离，然后枕状包装被供应给一个折叠工位，枕状包装在此被机械折叠成最终完成的平行六面体形状。 By cutting the relative transverse sealing band separated from the package so that the pillow and pillow-shaped packages are supplied to a folding station, this pillow packs are folded mechanically into parallelepiped shape of the final finished. 被夹持在每对夹持件之间的管部分由加热装置进行热封，加热装置由夹持件之一支承，并用来局部熔化牢固地夹持在夹持件之间的两层热封塑性材料。 Is sandwiched between the pair of clamping members each portion of the tube is heat-sealed by the heating means, the heating means is supported by one of the clamping members and for locally melting the fixedly sandwiched between two layers of heat-seal holding member plastic material. 当热封完成时， 一个切断件被致动以沿着横向密封带的中心线切断管，因而将枕状包装从包装材料的管的底端分离，该切断件由夹持件之一支承并与包装材料的管互相作用，因此底端被横向密封，并且夹持件在到达底部死点中心位置时被打开以避免妨碍管的上述部分，同时，另一对以同样方式操作的夹持件从顶部死点中心位置向下移动，重复如上所述的夹持/形成、密封和切断操作。 When the sealing is completed, a cutting member is actuated to the centerline of the transverse sealing band along the cutting tube, thereby separating the pillow pack from the bottom end of the tube of packaging material, the cutting member is supported by the holding member and one of the interacting with the tube of packaging material, so the bottom end is sealed transversely, and the holding member when reaching the bottom dead center position of said portion to be opened in order to avoid interfere with the tube, while the other pair of clamping members in the same mode of operation moves from the top dead center position downwardly, clamp described above is repeated / forming, sealing and cutting operation. 在已知的成形设备上遭遇到的一个问题关系到所谓的&装饰纠正& 系统。 In the forming device of a known problem encountered related to the so-called &decoration correcting& systems. 即，在最后形成包装的外表面的部分上，包装材料的幅板通常包括一连串等距的印刷图像或装饰，以致幅板必须以这样一种方式提供给成形设备，即在连续的装饰的情况下，包装的形成、密封和切断与装饰的接续&互相对正地&进行。 That is, in the final portion of the outer surface of the package is formed, the web of packaging material normally comprises a series of equidistant plates printed images or decorations that webs must be supplied to the forming apparatus, i.e., in the case of a continuous decoration in such a manner Under the package forming, sealing and cutting and splicing decoration &mutual positive way& to. 在实际使用中，由于装饰等距间隔开地印制， 所以每个装饰的位置相对于成形设备上的夹持件的位置可能改变，这首先是因为由夹持件施加在包装材料上的机械压力导致的包装材料的不同变形，其次是因为可倒出的食品在包装材料管内的脉动压力。 In actual use, due to equally spaced apart printed decoration, each decorated position relative to the position of the clamping member is formed on the device may be changed, this is primarily because of the mechanical member by clamping exerted on the packaging material different deformation caused by pressure of packaging materials, and secondly because pourable food pulsating pressure within the tube of packaging material. 因此需要一个用于纠正装饰的位置的系统，因为在很高输出速度下运行的包装机上，如果没有被实时纠正，即使在装饰位置相对于理论对正位置上的很小的变动也可能随着时间增加，从而导致生产出必须丢弃的不可接受的包装。 Therefore, the need for correcting a position of decoration system, because the output at high speed operation of the packaging machine, if not corrected in real time even in decorative position relative to the theoretical variation of the positive position may be as little time is increased, and thus must be discarded resulting in production of an unacceptable package. 在现代的包装机上，这种系统包括一个用来检测每个包装上的条形码位置的光学传感器；和用来将检测到的位置与理论位置比较的控制单元。 On modern packaging machines, such a system comprises an optical sensor for detecting the position of the bar
and means for detecting the position and the theoretical position of the comparison control unit. 在一些市售的机器上，每对夹持件都具有一对用来拉动包装材料管的牵引件，它们在每对夹持件中可移动地配装到夹持件之一上，在枕状包装的顶角和底角形成三角形的凸出部；和，在检测到装饰位置错误时，控制单元调节包装材料幅板的进给马达的速度。 On some commercial machines, each pair of clamping members has a pair of pulling the tube of packaging material for a traction member, each pair of clamping members are movably fitted to one of the holding member, the pillow shaped package top and bottom corners of the triang and, when an error is detected decoration position, the control unit adjusts the packaging material web feed motor plate speed. 如果该纠正不够， If the correction is not enough,
那么牵引件被控制稍微增加或减少在包装材料上的拉力。 Then the traction member is a slight increase or decrease the tension control on the packaging material. 在其它的机器上，控制单元直接对牵引件起作用，而不可能调节包装材料幅板进给马达的速度；并且操作被重复直到装饰的位置与理论位置一致。 On other machines, the control unit acts directly on the traction members, but can not adjust the web of packaging material sheet fee and the operation is repeated until the position is consistent with the theoretical position of decoration. 最近，已经设想出解决方法，由该方法，通过调节该对作用于管上的夹持件的移动和定时来控制包装材料上的装饰的位置。 Recently, a method has been devised to solve, by this method, by adjusting the timing of movement and acting on the tube gripping member to control the packaging material decoration position. 例如，如在意大利专利1296062中所述的，通过一个连续线性致动器对牵引件进行操作，例如一个气压缸，该气压缸被安装到成形设备的支撑结构上，由装饰纠正系统的控制单元致动，并通过传动装置连接到牵引件。 For example, as described in Italian patent 1296062, the traction member through a continuous operation of the linear actuator, for example a pneumatic cylinder, the pneumatic cylinder is mounted to the support structure forming apparatus by the control unit of the system to correct the decoration actuated, and is connected to the traction members by transmission means. 更具体地，在所述的情况下，传动装置包括一个致动杆，该致动杆可移动地配装到配备牵引件的夹持件上，在一端配装一个挺杆件，并在相对的一端通过相应的铰接杆连接到牵引件上。 More specifically, in the case wherein the drive means comprises an actuator rod, the actuation rod is movably fitted to the holding member with a traction member, at one end is fitted with a tappet member, and at the opposite end to the traction member by respective hinge rods. 挺杆件又被安装成沿着一个凸轮轮廓移动，该凸轮可调节地安装在成形设备的支撑结构上，由一个运动转换组件连接到驱动件，并通过该驱动件可相对于支撑结构移动。 Lifter member has been mounted is moved along the contour of a cam which is adjustably mounted on the support structure forming apparatus, by a motion conversion assembly coupled to the drive member, the drive member by the support structure relative to the movement. 换句话说，牵引件的操作需要极其复杂的、笨重的传动装置来将运动从安装在成形设备的固定部分上的驱动件传递到安装在可移动夹持件上的牵引件，因此包含了成形设备的支撑结构和夹持件上的大量的零部件，因而极大地增加了包装机的总成本，并增加了花费在安装和拆卸成形设备来进行任何保养工作的时间。 In other words, the operation of the pulling element requires extremely complex, heavy transmission to transfer motion from the drive member is mounted on the fixed part of the forming apparatus to the traction member is mounted on the movable holding member, and therefore contains the molding large number of parts the support structure and the clamping members on the device, thus greatly increasing the overall cost of the packaging machine, and increases the cost of the installation and removal of the forming apparatus to carry out any maintenance work time. 已知的成形设备的复杂性由于夹持件而进一步增加，除了牵引件之外，夹持件通常还包括可移动件，例如所谓的&体积盒&，它们配合确定所形成的枕状包装的体积和形状，并且它们需要专用的致动装置。 The complexity of known forming apparatus further increased due to the clamping member, in addition to the pulling element outside the clamping member also typically includes a movable member, such as a so-called &volume boxes&, which is determined with the formed pillow-like packaging volume and shape, and they require a dedicated actuator means. 发明内容本发明的一个目的是提供一种由一个填充可倒出的食品的薄片包装材料制成的管生产密封包装的成形设备，并设计成消除与前述已知设备通常相关的缺点。 SUMMARY OF THE INVENTION An object of the present invention is to provide a pipe production by a filled food product can be poured out of a sheet packaging material sealed package forming apparatus, and is designed to eliminate the aforementioned drawback typically associated with known devices. 根据本发明，提供一种用于由薄片包装材料制成的管生产密封包装的成形设备，所述管被沿着一条进给路径供给并填充有可倒出的食品， 所述设备包括夹持装置，所迷夹持装置包括至少两个成形组件，每个所述成形组件具有一对夹持件，所述对夹持件彼此循环相互合作并循环作用于所述管上，以在等间隔的横截面处夹持和密封所述管，所述橫截面 According to the present invention, there is provided an apparatus for forming a sheet of packaging material from the production of sealed packages of a tube, the tube is fed along a feed path and filled with a pourable foodstuff, the apparatus includes a clamping means for holding the fan means comprises at least two forming assemblies, each of said forming assembly having a pair of clamping members, the circulation of the clamping members cooperate with each other and acting on said circulation pipe, at intervals to The cross section of the holding and sealing the tube, the cross section
