DS Smith launches new exclusion counting device

DS Smith Packaging is known for flat die-cut technology, and its company in Bristol, a port city in the west of the United Kingdom, is also renowned in the market. Recently, DS Smith's new discharge counting device has attracted special attention.

Mr. Mike COOk, manager of the company's adhesive box department, said: “Our company’s largest stick-counting device is dedicated to the production of packaging cartons for eggs. The interlocking bottom and narrow structural design of this type of cartons have increased. One of the bottlenecks is the counting row (10) device at the bottom of the carton forming equipment."

In order to cope with the miniaturization trend of the carton demand market and changes in design requirements from large customers to the horizontal lines, the company has established a special research team to seek solutions for the production of such cartons. Mr COOk said: “Now, many of these cartons are used for display and display. The popularity of 8 packs of egg cartons is comparable to that of the past 16 packs of eggs. The problem is that the small cartons are already below. Most carton forming machines can produce standards, so they can usually only be produced together, which increases the difficulty of production."

With a series of equipment installed at various production sites by DS Smith Packaging, the research team was able to observe possible solutions in various departments. After visiting the factory in Fordham, Cambridgeshire, the team was fortunate to see the current state-of-the-art counter ejector suitable for installation on the standard “隹” Marti” cartoner. Mr Cook recalled: “Obviously, this is to solve this problem. The key to a problem. From the point of view of mechanical physics, the carton will not be obstructed in the Martin discharge counting device. When buying Martin924, this eject counting machine has not yet been born. However, we quickly realized that installing this device can solve 95% of the carton discharge count problem. ”

A few hundred miles from Bristol, another DSSmith Packaging facility in Launceston is also installing a new counting vent for their Martin 924. The die-cutting speed of the current die-cutting machine in this factory has been greatly improved over the past, but its production efficiency is limited by the bottom counting discharge device.

The MartinTop Counter Ejector counter ejector is designed to stack die-cut, folded or unfolded cartons, while also including uncut cartons. Thanks to its independently driven motor, it is easy to work with any cartoner, not just the Martin line. The unit's excellent performance enables efficient stripping and accurate counting. The first carton coming down from the cartoner falls on the separating guide. When the carton is stacked, the easily adjustable air spout ensures that the top carton is always closed, and a moving supporting object flattens the carton stack to ensure that the carton bundle is always in optimum condition. When the counting device counts the number of cartons, the separating guide pawl is quickly retracted so that the carton stack falls onto a lower conveyor with a built-in lifting table.

The conveyor transports the carton stack away. The pressure belt at the top ensures that the paste will work smoothly. Finally, the bales of cartons come out of the counting and discharge unit and wait for the next step of loading or baling.

Bobi Group's PhiI Dobson said: “The counting and discharging method is more convenient for stacking cartons, including die-cutting cartons. The phenomenon of wrinkling is rarely seen, which can greatly improve the quality of finished cartons. The machine has excellent performance and its handling. The board size is the same as the bale size.The height of the stack can be processed from 80mm to 390mm.Because this unit has the function of short order circulation, it can handle small batches of large-size cardboard easily even when unmanned.

Mr. C00k was very satisfied with the results obtained after installing the new unit at the factory. He said: “In this way, we can launch new production projects. At the same time, we can also increase the production speed of existing machines. Although it is still in the exploratory stage, it is short. In a short period of three months, we have taken a big step forward from the established goal - equipment performance has increased by 20%! I think there is still a possibility of further improvement.

In addition to the increase in production speed, Mr. Cook is also quite satisfied with the rate of waste reduction. He said: "After installing the new unit, we have to deal with the number of clamped cartons much less than in the past. At the same time, because the bales and discharges are almost frictionless, there is no damage to the cartons. Of course, we still need Improve operating skills.
