CoBo-Stack

Automated stacking

The MBO CoBo-Stack is a so-called cobot, that is, a collaborative robot which needs no protective cage. Product stacks, e.g. stacks of folded signatures, are transported from the delivery onto the table of the CoBo-Stack. The cobot picks up the stacks from the table and deposits them on pallets. This is an enormous physical release for the operator at the delivery. The pallets can be positioned on both sides of the delivery, allowing uninterrupted operation. While the MBO CoBo-Stack is filling one pallet, the operator can move the loaded pallet away and prepare the next empty pallet.

An indicator lamp lights up in different colours, signalling various operating statuses of the cobot to the operator. For some operating statuses, there is an additional acoustic signal. This means that there is no need for the operator to remain directly at the production machine, giving him or her time to carry out administrative tasks, for example quality control or preparing the next job.

The CoBo-Stack stacks pallets up to 140 cm (55") high.

All products in the format range from 3 3/4” x 5 7/8” and 10 1/4” x 13 3/8” can be automatically placed from the delivery to the pallet.

The MBO CoBo-Stack can stack on four different pallet positions.

Product stacks weighing up to 8 kg (17 5/8 Ib) can be moved.

Who is the MBO CoBo-Stack suitable for?

Designed for maximum flexibility, the MBO CoBo-Stack is suitable for a wide range of firms who process signatures. Like a standard delivery, it can be repositioned within just minutes. In addition to its use on folding machines from a wide variety of manufacturers, it is also designed specifically to work with saddlestitchers and perfect binders. Should the space conditions require it, one of the two pallet spaces can be deactivated.

The maximum pallet height can be extended from 90 cm (35 1/2“) to 140 cm (55“) as an option. The maximum stack weight can be extended from 6 kg (13 lb) to 8 kg (17 5/8 lb). This means that the CoBo-Stack can be ideally adapted to your individual requirements.

Compatibility with other units

Stacker deliveries from a wide range of manufacturers

The CoBo-Stack works autonomously and is therefore suitable for use on stack-dispensing delivery units from a wide range of manufacturers. The year of construction is also irrelevant. The A80 delivery from MBO was specifically developed for use with the CoBo-Stack. It can be used to optimise the transfer speed of the stacks and allows a comprehensive connection to the folding machine.

Saddlestitchers and perfect binders

To the CoBo-Stack, a stack is a stack. Many of our customers also use the cobot directly behind the outlet of their saddlestitcher or perfect binder. Once work is complete, the CoBo-Stack can be easily and quickly repositioned behind the delivery of a folding machine.

Features

Standard features:

Cobot – collaborative robot which does not need a protective cage
Two pallet spaces possible; this allows one pallet to be prepared whilst the other is being loaded
Optical and acoustic signals for indicating different operating states
Retrofittable to existing delivery systems, for example MBO A500/A700, MBO A80 as well as to delivery systems from other manufacturers, to saddlestitchers and to perfect binders
Receiving the stacks from the left-hand side of the delivery
RAS router included; access permission from customer is mandatory
Two different signatures can be deposited separately on the same pallet
With double stream production, it is possible to deposit on the left-hand and right-hand pallets alternately

Additional features:

Open, electrical interface for third party machines
Receiving the stacks from the right-hand side of the delivery
Camera from below for depositing two different signatures on the left / right, for example in double stream production
