盒装是包装的过程or productsare loaded into cases,盒子or trays. These are usuallycorrugated boardbut may also be fluted plastic, heavy non-flutedboardor other materials. In some instances, such as milk in bottles and cartons, specialized metal or plastic returnable crates are used. For simplicity, this white paper will use the word “case” generically to cover all variations.只有细微的不同,箱包装都是一样的gardless of whether it is an RSC case, a tray, a箱or some other box.
箱子包装seems like a natural for using operators instead of machines. It is simple work so unskilled, relatively low cost, labor can beused并且自动化美元可以为其他事情保存。实际上，没有这样的事情low cost劳工。薪酬很高，而且上升qualified employees继续越来越难找到。外壳包装也是重复的，通常很重，，，，work with a lot of ergonomically hazardous lifting and bending. This can添加to workers compensation claims.
An automated casing machine is relatively simple and generally very easy to justify.
“案例包装”一词经常用于描述将包装进入案例的完整过程。In reality, the回覆至少3个离散操作：
- Case erection
there can also be placement of internal partitions, slip sheets if more than a single layer of product is packaged, leaflet and instruction insertion.
the entire process may be done on a single casing machine or multiple machines. This white paper will focus only on the case packing, regardless of where erection and sealing一世sdone.
there are three majormethodsof automatic case packing: Side loading, vertical放置andverticaldrop packing.有些人可能认为环绕箱形成也是案例包装。它超出了本文的范围，将在未来的有关Caser勃起/形成的论文中涵盖。Each method hasa number of根据机器设计以及包装和产品要求的变化。the techniques discussedhere also通常申请托盘包装。所选的方法将在很大程度上取决于要包装的产品的性质。

the words “case” generally refers to a box made of corrugated board. Occasionally fluted plastic, similar dimensionally and functionally to corrugated board, may be used. The RSC (Regular Slotted Case) case is made from a single piece of board, die-cut, scored, folded and glued at the converter. RSC cases are the most common though there are a number of other styles depending on product need.
It is simple to erect RSC cases by hand and do it fairly quickly provided the workstation is properly designed. There are aids that make it even easier. Ergonomics and lablr availability are 2 good reasons to automate the task. Automation will pay for itself quickly
this case erector from the Frain inventory is about as simple as it gets. Knocked down case blanks are placed in an inclined magazine and feed by gravity to holdback fingers in the pick-off station.
An articulated arm grips major side of the case blank with suction cups and pulls it from the magazine. As it does, an articulated section of the gripper folds the minor side open and tucks the trailing minor flap under. The arms square the case and push it into the takeaway section. There an end guide pushes the leading minor flap closed and side guides fold the major flaps closed.
A glue or tape head may be incorporated into the case erector to seal the bottom closed. In some applications, the bottom is left unsealed until after case packing when top and bottom are sealed simultaneously on a case sealing machine. One issue with this style of case erector can occur with a sloppy glue joint. Excess glue can glue the interior panels of the case and the case erector may not be able to pull it open.
this is never acceptable as it will cause a jam. On higher speed, 15 case/minute and up a different style case erector will be used. This horizontal erector by RA Pearson brings the case blanks into the machine horizontally.
作为索引到装配区域,gripped by suction cups underneath. An arm with suction cups rotates down, grips the top major side of the case. It pulls it forward and up to open it. Gripping both top and bottom of the case allows the erector to pull the case open even if it is glued shut by sloppy gluing.
A final step is to compress the case bottom between a backing plate and a ram with a mandrel. After exiting compression, the case falls upright onto a takeway conveyor.
After the case is erected, the packed needs to be placed. There are several automated ways to do this. Where feasible, drop packing is often the simplest and fastest way to do it.
Drop packing drops the product into the case. Sounds simple but there are some caveats.
- the product must be rugged enough to survive the drop. This is not usually an issue because the drop is not as violent as it sounds. Glass beverage bottles are commonly drop packed.
- the product must fall smoothly. This limits drop packing to rigid packages such as bottles and cans. Irregular products like bags are not suitable to drop packing. Small, lightweight or empty bottles may not be good candidates for drop packing.
Products must first be collated in the final pack pattern. This is done by multiple infeed lanes. For a 12 pack, this normally means 3 lanes of product, though 4 is possible.
Backpressure in the accumulation area pushes the bottles (4 in this example) over the drop gate. Once in position, the back pressure on the group is relieved.
While this is happening, an empty case, tray or reusable crate is being positioned under the drop gate.
the sketch omits 2 critical components in the interest of clarity:
- Often, but not always, an elevator raises the case to minimize the drop distance. This elevator may be timed with the drop so that it is moving downward as the bottle fall, minimizing impact. This can be an important feature when running glass bottles or jars.
After the drop, the full case is taken away on the conveyor and the process repeats.
When the case is a standard RSC and the product is straightforward, all 3 machines may be combined into a single, all-in-one case erector-packer-caser. There are several advantages to this:
- the combined machine has a smaller footprint than 3 standalone machines would.
- the case and product are under positive control at all time. There is no need to stage the case into successive machines.
- the combined machine is simpler than 3 standalone machines.
the case erector may be located below the case packer infeed. Case blanks are placed in a magazine and held in position for opening. An articulated arm with vacuum cups grips the flat case on both sides of the score line and pulls it out of the magazine. As it does so, the section of the arm gripping the rear portion of the case folds 90 degrees opening and squaring the case.
the case moves to the packing area. Product may be dropped into the case with a drop packer or placed using a robot or other pick and place mechanism.
A casing machine is a machine that automatically, sometimes semi-automatically, load products into corrugated RSC cases. There are a number of styles depending on product and speed, but most are vertical, loading into the open top of the case. This allows gravity to help the process.
Some cases, such as a 24-pack of cans, are designed so that loading flaps are on the ends rather than the top and bottom. Other products, such as cartons do not lend themselves to vertical loading even though the case has a top and bottom.
Side load casing machines load horizontally rather than vertically.
Products are collated into the proper pack pattern in a separate system or as part of the machine infeed. These collated products are staged in the loading section of the caser.
情况下安装可能是手动完成的,在一个单独的case erector or on the same caser. If formed vertically, it will be necessary to tip the case on its side prior to the loading area.
Guides will typically be used to hold the front flaps out of the way to avoid interference during loading.
Once the case and product are aligned, the product is pushed into the case. In some patterns there may be double layers of product. These may be handled by either stacking the product double deep and pushing with a single push or making two separate pushes. Machine design, case and package will determine which is to be done.
A common configuration for the robotic casing machine uses 2 conveyors. Cases are erected, either by hand or machine, and conveyed to a staging station near the robot. Meanwhile, the product is staged in a nearby station. The closer together all 3, robot and 2 staging stations, can be, the shorter will be the robot travel. Shorter travel means faster cycle time, less wear and tear on the robot and smaller overall footprint.
Where possible, product should be staged in its final packing format. If bottles are to be packed in a 4X3 pattern, the conveyor can be divided into 3 lanes before the staging station. A backpressure relief mechanism isolates the 4 bottles at the end of each lane. The robot, with an appropriate gripper, picks up 12 bottles at a time and places them in the case. The case is released to the case closer/sealer.
It is possible to pick 4 bottles at a time from a single lane but this will require 3 cycles of the robot and each placing position will be slightly different.
An advantage of the 6-Axis robot is that one robot may be able to pack for 2 separate lines. The case and bottle staging area of each line remain the same with the robot in the center. As the robot is loading one case, the case and product for the other line is staging.
Some lines may be too fast for 6-Axis robots. Delta and SCARA robots can run much faster and may be a solution in these applications. A drawback may be their limited reach compared to a 6-Axis robot.
