Case Study
Workplace layout for two employees with multiple disabilities in the manufacturing of blanks

Employer:

The company was divided into two independently operating areas. This restructuring measure was associated with changes in the production process and led to the release of jobs in several areas. In the production of circuit boards, the employer plans to expand production. Essentially, these will be series with small and medium-sized quantities, which require an increased changeover effort.

1. employee

Disability and functional restrictions:

- epilepsy - High blood pressure - spine disease - Right elbow joint movement restriction Due to the disability, freedom of movement (posture) and lifting and carrying loads is restricted. In addition, the man can only be used to a limited extent for energetic or static or dynamic muscle work in which the cardiovascular system is stressed. The GdB (degree of disability) is 70.

Training and job:

The employee is a trained watchmaker. He has been with the company as a production assistant for many years.

2. employee

Disability and functional restrictions:

- High blood pressure - spine disease - hip joint disease Due to the disability, the freedom of movement (posture) and the lifting and carrying of objects is restricted. In addition, the man can only be used to a limited extent for energetic or static or dynamic muscle work in which the cardiovascular system is stressed. The GdB (degree of disability) is 50.

Training and job:

The employee is a trained agricultural machine fitter. He has been with the company as a production assistant for many years.

Workplace and duties:

The existing, manually operated, screen printing machine is ergonomically very unfavorable. In particular, setting up and converting the machine requires, because of the unfavorable position of the control elements, climbing onto boxes and a posture with the upper body bent forward. In this position, micrometers must also be used correctly up to ten times per shift. The cover of the screen printing system, which is open for retrofitting, is so inappropriately attached that it is almost inevitable to hit the head when carrying out the setup work. In addition, with this device, the boards have to be inserted and removed individually by hand, which binds the operator to the machine and its work cycle in a constant standing / walking posture and requires frequent stooping. In order not to endanger the functional safety of the boards by hand sweat, light latex protective gloves must always be worn when inserting and removing them. If the printing conditions are unfavorable, the stencils can become dirty more often, which must then be removed and cleaned manually. Again, unfavorable forced postures have to be taken. For reasons of disability, it is not possible for the two employees to work permanently on the existing screen printing system. The restructuring in the production area will soon eliminate these jobs. It is planned to transfer the two employees to the circuit board production, where they will use a screen printing machine in alternating layers to apply solder paste to the circuit boards. For this reason, the employer intends to purchase a precision screen printing machine with PC control, cassette magazine device and stencil cleaning device. This machine is also equipped with a motorized transport width adjustment and film clamping frame for the direct mounting of metal templates with pneumatic clamping device. Manual adjustments and conversions are no longer required on this machine. Stencil cleaning by hand is largely eliminated, since the boards from magazines are automatically fed to the system and also transported back again. This eliminates the constant bending down and wearing latex gloves, which is perceived as unpleasant. All inputs into the PC and the monitoring of the system can be done in a sitting or standing posture. The operators no longer have a clock-related requirement. In addition to entering control commands and monitoring work processes, the only thing that needs to be done is to replace the cassettes with the circuit boards. The completely closed machine does not require any intervention in the running machine. The use of people with epilepsy in this area can therefore also be carried out without additional occupational safety devices.

Keywords and Further Information

Funding and participation:

The integration and inclusion office granted the employer a subsidy of 38 percent of the costs incurred. The advice was provided by the technical advice service of the integration or inclusion office. The old plant will continue to be on standby for reserve purposes and emergencies and will therefore not be given in payment. Considerable additional costs arise from the special equipment of the new machine, which are of particular importance for reducing or avoiding physical and psychological stress on the employees at this workplace.
