2019年1月杂志_标识小贴士:工具选对 效率翻倍

2019-01-07

From year to year, many companies change the products they make, or begin producing new product lines in niche areas that require new and different finishing methods. In some shops, the steps taken to finish products are done with inappropriate tools.

年复一年,许多公不断变换他们产品类型,或开始在利基领域开发新的生产线。在一些工厂中,他们完全是用错误的工具去制造产品。

 

Furthermore, many shops keep their laminators, cutters and other finishing tools too long and put off new purchases or upgrades, which negatively affects productivity and quality.

此外,许多工厂的覆膜机、剪刀和其他修整工具使用时间太长,工厂又没有及时对工具进行更换或升级,就会对生产出的产品造成负面影响,比如生产力下滑或产品质量下降。

 

This article examines tools used in the finishing marketplace and will address opportunities for better and more efficient production for the future.

本文将为大家带来如何整理打印工厂中的工具,并一起探讨未来更好、更高效的生产技巧。

 

Finishing Solutions for Banners and Textiles

横幅和纺织品的整理解决方案

 

Sewing Machines

缝纫机


A variety of industrial sewing machines are available to finish items made of varying vinyl grades such as banners. Finishing banners by sewing pole pockets and hems is standard work for many imaging businesses. Some companies try to use consumer-grade sewing machines, but they stitch too slowly to work efficiently. Consumer-grade units generally stitch 1,000 stitches per minute, while industrial units can move material in thousands of stitches per minute. This higher productivity is necessary for sewing products in a reliable and repeatable manner.

工业缝纫机可用于完成由不同乙烯基种类制成的物品,如横幅。它的工作原理是由机针带引缝线穿过缝料形成的线环后,勾住这个线环使之形成线迹的标准工作。一些公司试图使用普通的缝纫机工作,但它们缝合得太慢,效率不高。一般来说,普通的缝纫机每分钟可缝1000针,而工业单位每分钟可缝数千针。这种更高的生产率对于生产产品来说既有质量也更有效率。

 

The feed movement on a consumer-grade sewing machine utilizes a set of toothed, metal walking plates that move under the material, pressing it up onto the machine’s presser foot. In contrast, a dual (or unison feed) commercial sewing machine is a better investment. Also known as “walking foot machines,” these units have a presser foot with its own set of gripping teeth that walks in unison with the bottom feed to facilitate double feeding of the material. The end result is a larger, more consistent stitch. These machines typically are used by upholsterers and people who need to sew heavy-grade industrial fabrics.

脚踏式缝纫机是使用者踩动脚踏板,通过曲柄带动皮带轮的旋转,又通过皮带带动机头旋转。相比之下,工业缝纫机对于工厂来说是更好的投资,因为它生产效率高。工业缝纫机根据缝料不同的用途,每分钟能缝制1000~10000个线迹,而且专用性强,大部分工业用缝纫机是为某种特定工件,甚至是为某一特定缝制工序而专门设计的。

 

The one-needle, unison-feed lockstitch is the most common type of industrial sewing machine in use. Double-needle, chain-stitch machines also are used. They use four thread spools that feed from the unit’s top and do not require the bottom bobbin thread to be changed. These are a better choice for companies producing large volumes of work without interruption. Given the many variations and options found on industrial machines, talking to a manufacturer may be the best way to narrow down the possibilities.

单线和多线链式线迹缝纫机是一种应用很广的工业用缝纫机。它的机头由刺布机构、钩梭机构、挑线机构、送料(差动或无差动)机构组成。缝制速度每分钟可达7000个线迹。它缝制的链式线迹富有弹性,可随着缝料的被拉伸而扩展、缝料的复原而收缩。特别适于缝制穿着时需要扩展和复原的针织服装。如果按线迹形成过程的逆向牵拉缝线,则能容易地将线缝解开。因此,它又可缝制以后需要解开线缝的装载袋封口等。对于生产大量工作的公司来说,工业用缝纫机这是一个更好的选择。

 

 

Sticky Alternatives to Stitching

粘合的替代方案


Instead of sewing hems and pockets onto banner or textile pieces, you can use double-sided adhesive tapes. These tapes — known as “banner hem tape” or “double-sided hem tape” — are useful for creating quick hems in lightweight banner materials. If you are using tape for heavier materials or pole pockets, look for “very-high-bond” (VBH) tape.

你可以用双面胶代替在横幅或纺织品上粘贴贴花或口袋。这些胶带被称为横幅边胶带双面胶带可用于在轻质横幅材料中进行快速粘贴。如果需要粘合的材料较重,那就使用VBH(高粘合)的胶带。

 

VHB tapes have enormous gripping power and are used when material stress is of concern, there is no access to a sewing machine or the project requires tape for the intended product life. Hem tapes also can be used in a one-sided application as a reinforcing material when inserting grommets. Vinyl that is not reinforced is a soft material in which grommets have a tendency of tearing out under stress. Using reinforced hem material, a high-strength plastic that has an adhesive on one side, solves this problem. It is applied to the banner’s back before grommeting.

VHB胶带具有强大的粘贴性,适用于缝纫机无法使用、材料较大或产品需要胶带延长产品寿命。折边胶带也可以在作为加固材料时使用,未加固的乙烯基是一种软材料,这种材料有些时候容易撕裂,所以可以采用增强性折边材料,它是一种有粘合剂的高密度的塑料,一般适用于帐篷等织物背面的压胶处理。

 

Banner Welding

横幅焊接


Vinyl welding, a strong improvement to stitching, is the only way to seam together really large vinyl projects. Vinyl welders come in a number of different designs, depending on a facility’s size and usage requirements. Units can be portable tools or industrial, non-movable equipment.

乙烯基材料焊接是材料拼接的一种有力改进,是将真正大型乙烯基工程缝在一起的唯一方法。乙烯基焊机有许多不同的类型有可移动的便携性装备也有不可移动的工业型,取决于产品的大小和生产要求

 

Hot Air or Hot Wedge

热楔


 

Vinyl welders all work via heat and pressure. Heat sources are electrically produced, high-temperature air or electronically heated, high-temperature wedge — which is precisely controlled and injected between two or more layers of thermoplastic material. Heating the thermoplastic material prepares the two surfaces to be joined for molecular bonding.

乙烯基焊工通过给材料加热和加压工作。电气产生热源,高温加热两个待连接的表面以进行分子结合。 

 

Hot air rotary heat sealing is used to join thermoplastic industrial fabrics and films using precise heat, speed and pressure settings. Hot air temperatures for these units can range from 537.8oC (1,000oF) to as high as 732.2oC (1,350oF). On these systems, a heated wedge is positioned precisely at the weld point, providing the required heat. The fabric or film is then pulled across the heated wedge.

旋转热封用于热塑性工业织物和塑料薄膜。对塑料薄膜的两个接触面加热,使其处于熔融的热塑化状态,再给封接部位施压,使薄膜两个封接面融合密封牢固。影响封合质量的因素主要是加热温度、封合压力和和作用时间。旋转热封机能精确定位在焊接点处,提供所需的热量。

 

There are strong advantages to both rotary welder types. Wedge welders can use less power than their hot air counterparts and do not have the noise associated with hot air blower systems. However, hot air systems can provide a better, more dependable bond. Also, for substrates that are not always produced perfectly, hot air systems seem better suited in dealing with these variations.

热楔焊接机可以使用比旋转热封机更少的功率,并且没有与热封机系统相关的噪音。然而,旋转热封机可以提供更好,更可靠的粘合。此外,对于容易变形的生产基材,旋转热封机似乎更适合处理这些变化。

 

 

 

Radio Frequency Welding

射频焊接


Radio frequency (RF) welders are another vinyl seaming technology that have been around for a long time, predating rotary and hot air systems. In RF welding, electrical energy in a radio frequency field is conducted to the surfaces that will be joined together. This stimulates the material’s molecules to move at a speed of tens of millions of times per second. The friction (heat) arising between the molecules is what fuses the material together. A weld seam is created, which has the same strength as the surrounding material.

射频焊是另一种乙烯基接缝技术,已经存在很长时间,早于旋转热封热楔焊接。在射频焊接中,射频场中的电能被传导到将要连接在一起的表面。这刺激材料的分子以每秒数千万次的速度移动。分子之间产生的摩擦(热量)将材料融合在一起,使其具有与周围材料密度相同的焊缝

 

For grand-format RF welding, the seaming head is on a traversing rail that runs the length of a long, narrow table. Companies such as Zemat and Forsstrom High Frequency AB have units for seaming together billboards. Of all vinyl seaming technologies, RF units are the most expensive and consume the most energy. They are used from automobiles, swimming pools, tarpaulins and electronics to the food industry, and are widely used in material sealing and welding.

ZematForsstrom High Frequency AB等公司都有将广告牌缝合在一起的大规格射频焊接装置。在所有的乙烯基封接技术中,射频装置是最昂贵和消耗能源最多的。从汽车、游泳池、防水布、电子产品到食品工业,射频装置广泛应用于材料的密封、焊接。

 

 

 

Hand-Held Cutters

手持式切割

 

Specialty hand tools can save a lot of time and frustration. The Plast-Kut can be used for scoring and cutting fluted Coroplast® or similar material. The Coro-Claw™ works like the Plast-Kut on 4-mil or 11-mil material. With the Coro-Claw, two square, metal rods fit into the material’s flutes, guiding the knife blade. If your company needs to make shapes or cut in a straight line, check out these tools.

专业的手工工具可以节省大量的时间Plast-Kut可用于刻划和切割Coroplast®等类似材料,Coro-Claw™的使用方式是将两根方形的金属棒插入材料的凹槽,控制刀片。如果您的公司需要制作形状或直线切割,可以考虑一下这个工具。

 

 

For synthetic or other fabrics, the use of a rotary cutter results in a cleaner cut, without pulling out threads or leaving behind a fuzzy edge. Even better than the rotary knife for use on heavy synthetics is the “hot knife.”

对于合成或其他织物,使用旋转刀具可以实现更整齐的切割,而不会拉出螺纹或留下模糊的边缘。

 

Hot knives come in a variety of models with many different cutting tips to choose from. The advantages of a hot knife include the ability to seal the edges of synthetic material as the cut is made. This also works for webbing, cords, rope and heavy gauge synthetics.

热刀有多种型号,有许多不同的切割类型可供选择。热刀的在切割时密封合成材料边缘的能力。这也适用于织带,绳索和重型合成材料。

Air Cleaners

空气净化器


 


For a cleaner environment, air-filtration units help reduce airborne dust and dirt. One manufacturer, Island Clean Air, has units with dust filtration and activated charcoal to lower levels of air pollutants (volatile organic compounds or VOCs) emitted from mild-solvent and solvent-based inkjet printers.

为了环境的清洁,空气过滤装置有助于减少空气中的灰尘和污垢。海岛清洁空气公司(Island Clean Air)是一家制造商,该公司生产带有粉尘过滤和活性炭的设备,可以降低溶剂型喷墨打印机排放的空气污染物的含量。

 

These air cleaners may be used with flexible piping — much like the vent hose on a clothes dryer — that connects directly to the exhaust ports found on many printers. Room scrubbers, which clean ambient air, capture fumes only after they have entered a room or space, not at the source. Shops that utilize higher solvent ink volumes or cleaning solvents that are more volatile may benefit from using potassium permanganate grids with activated charcoal to achieve higher VOC capture rates.

这些空气净化器可以与柔性管道一起使用就像烘干机上的排气软管一样直接连接到打印机上的排气口。使用高溶剂墨水量或挥发性强的清洁溶剂的商店,可以通过使用高锰酸钾网格和活性炭来清洁周围空气

  

Also available for inkjet printing systems are custom hoods, which are made for specific inkjet printers by PAT Technology Systems Inc. PAT is a Canadian corporation that sells portable HEPA air purifiers and humidity solutions to the printing industry. The company’s custom manufactured hoods capture air directly at the source and vent it through flexible piping to a filtration unit. The advantage of these units is that they capture fumes at the source, before the pollution has dispersed into the room.

喷墨打印系统也可定制喷墨防污染机罩,这是由PAT技术系统公司为特定喷墨打印机生产的。PAT是一家加拿大公司,向印刷行业销售便携式高效空气净化器和加湿器。该公司定制的空气净化器直接在源头捕获污染物,通过柔性管道将其排放到过滤装置。

 

Dust Removal for Print Finishing

印刷除尘装置


There is nothing worse than laminating or mounting prints only to find dust either under the laminate or under the substrate. Many shops use an air hose to clear dust, but high-speed air blowing over most plastics can cause static to build up on the surface, attracting even more dust. The best approach I’ve found to clear dust immediately prior to lamination is through a polymer roller. These slightly tacky rollers grab any particles from the side of the print and substrate that is to be laminated.

没有什么比覆膜或印刷后在层压或基板下发现灰尘更糟糕的许多商店使用吸尘器清除灰尘,但高速空气吹过大多数塑料会导致静电积聚在表面上,从而吸引更多的灰尘。我发现在覆膜前清除灰尘的最好方法是通过聚合物滚轮。这些微粘的滚轮可以从印刷物的侧面和要层压的基材上粘住任何颗粒。

 

Dirty machines, tables and dusty operators are the first priority for dust removal. Operators can use an air hose to de-dust themselves after using any saw in order to remove wood, plastic or metal particles from their hair and clothing. This should be done far away from the finishing area.

积满灰尘的机器、桌子操作员除尘的首要任务。操作员可以在工人工作后使用除尘设备来除尘,以清除头发和衣服上的木屑、塑料或金属颗粒。
