Definitions

  • the present invention relates to an opening mechanism arranged to open a cuff of a garment, and to a method for controlling an opening mechanism.
  • the present invention also relates to an opening device, and to a method for controlling an opening device.
  • the present invention also relates to control units implementing these methods.
  • the present invention also relates to a garment donning machine. The present invention aims at facilitating donning a garment on a part of a human body..
  • the embodiments of the present invention are often described in relation to gloves, such as e.g. disposable and/or sterile gloves.
  • the present invention is not limited to usage in connection with gloves. Instead, the present invention may be generally utilized for donning essentially any type of garment on essentially any body part, such as e.g. socks on feet, as is clear from the claim wording .
  • Disposable and/or sterile gloves are today used by per sons /employees in a number of different areas/pro professions, such as e.g. in the health care sector and the food industry. Disposable and/or sterile gloves are typically worn to protect the hands of the user and/or to prevent spreading of bacteria and other agents. Due to current stricter hygienic requirements, safety aspects and virus spreading prevention, the use of disposable and/or sterile gloves has been rapidly increasing, and is likely to continue to increase in the future .
  • a conventional glove donning machine uses vacuum or suction to inflate the glove for allowing the hand of the user to be inserted into the glove.
  • vacuum or suction is the noise produced by the vacuum pump.
  • it is difficult to control the suction power such that the glove can be opened properly for donning, without damaging the glove .
  • a general problem for such complex conventional glove donning machines is that they are not quick enough, i.e. the process/sequence for preparing a glove for donning is too time consuming, and causes delays when in use.
  • An objective of embodiments of the present invention is to provide a solution which mitigates or solves the drawbacks and problems of prior art.
  • an opening mechanism arranged to open a cuff of a garment; characterized by - a first insertion member arranged to be controlled by rotation of first and second arms arranged to be rotatable around first and second axes, respectively, whereby the first insertion member is arranged to move linearly between a first centered position and a first opened position; and
  • a second insertion member arranged to be controlled by rotation of third and fourth arms arranged to be rotatable around third and fourth axes, respectively, whereby the second insertion member is arranged to move linearly between a second centered position and a second opened position;
  • first and second insertion members in the first and second centered positions are adjacent to each other to facilitate insertion into the cuff, and in said first and second opened positions are spread apart to open the cuff .
  • the first centered position of the first insertion member can also be referred to as a first closed position, a first cuff inserting position or a first position of the first member.
  • the second centered position of the second insertion member can also be referred to as a second closed position, a second cuff inserting position or a first position of the second member.
  • the first opened position of the first insertion member can also be referred to as a first cuff opening position or a second position of the first member; and the second opened position of the second insertion member can also be referred to as a second cuff opening position or a second position of the second member.
  • An advantage with this opening mechanism is that an automated expansion of the cuff of the garment can be achieved which is both simple and fast.
  • the linear movements of the first and second insertion members, cooperatively caused by the rotation of the first and second arms, and the third and fourth arms, respectively, allow the opening mechanism to be made both compact, non-expensive and robust.
  • the first and second insertion members are close together in their centered positions and can thereby easily be inserted into the opening/cuff of the garment.
  • first and second insertion members are separated from each other in their opened position such that the cuff of the garment is expanded, whereby donning of the garment, e.g. on a hand, is facilitated.
  • the cuff of the garment is expanded by the linear movements of the first and second insertion members inside the garment, which efficiently and safely open the cuff to facilitate donning.
  • first and second insertion members By the first and second insertion members being caused/controlled to their respective linear movements, from their first and second centered positions to their first and second opened positions, respectively, a substantial expansion of the cuff of the glove can be achieved in a simple and quick way.
  • the first and second insertion members can hereby be easily inserted/entered into the cuff of the glove at reception of the glove, and can then quickly be separated such that donning of the glove on a hand is facilitated safely and with little delay.
  • the well controlled linear movement of the first and second insertion members also results in a low risk for damaging the glove when opening it for donning.
  • the number of possible gloves donned per time unit is increased by the opening mechanism.
  • the linear movements of the first and second insertion members follow a line/direct ion passing a first central point between the first and second axes, and a second central point between the third and fourth axes.
  • the movements of the first and second insertion members are well defined and predictable, such that the risk for malfunction and damaged garments is reduced. Also, the linear movements make it possible for a donning apparatus including the opening mechanism to be made compact.
  • the first insertion member includes first and second elongated slits in which the first and second arms, respectively, are displaceably connected to the first insertion member;
  • said second insertion member includes third and fourth elongated slits in which the third and fourth arms, respectively, are displaceably connected to the second insertion member.
  • the displaceable connection between the arms and the insertion members, and thereby also the linear movement of the first and second insertion members is provided by a robust and low complexity solution.
  • An advantage with this embodiment is that the design, using the cooperatively controlled linear movements of the first and second insertion members, provides for quick, robust and substantial movements within a small space/cabinet of the apparatus, whereby a compact apparatus is provided. Further, synchronized and smooth linear movements of the first and second insertion members are achieved. Also, the first and second insertion members can by these linear movements easily be inserted into the opening/cuff of the garment at a garment handover in a garment receiving position, since the first and second insertion members are neither sideways displaced nor tilted .
  • the first, second, third and fourth arms include first, second, third and fourth rods/pins/shafts/sticks, respectively, arranged in, and to be displaceable within, the first, second, third and fourth elongated slits, respectively, thereby providing the displaceable connection to the first and second insertion members, respectively.
  • the first, second, third and fourth elongated slits each have a slit length x allowing the first and second insertion members to perform their linear movements during rotation of the first, second, third and fourth arms.
  • the combination of the slits and the therein movable rods/pins/shafts/sticks, and the controlled rotating arms, provides the advantageous linear movements of the first and second insertion members. This is made possible since the rods/pins/shafts/sticks can move within their respective slit to compensate for the changing horizontal lengths between each axis and its respective insertion member during the arm rotations. Thus, the first and second insertion members are not pushed sideways or tilted during the rotation of the arms, because the rods/pins/shafts/sticks are moveable within the slits .
  • the slit length x is a function of an arm length L of the first, second, third and fourth arms, respectively, and of a rotational angle a for the first, second, third and fourth arms, respectively.
  • the slit length x is chosen to compensate for the changing distances between the first and second axes, and the first insertion member, respectively, and between the third and fourth axes, and the second insertion member, respectively, when the first, second, third and fourth arms are rotated to cause the linear movements of the first and second insertion members.
  • each one of the first and second insertion members have a form including a width adapted to a width of the cuff opening of the garment in a relaxed state.
  • Such a form of the first and second insertion members facilitates easy entry and insertion into the garment when the garment is handed over to the opening mechanism, and also facilitates donning of the garment.
  • each one of the first and second insertion members is provided with a groove arranged to receive a cuff edge of the garment.
  • the groove which may correspond to, and/or may be formed to receive, the shape of the cuff edge, provides for a solid grip of the garment, without damaging the garment when gripping and/or stretching it.
  • the first and second insertion members may also include two or more such grooves.
  • the first and second insertion members are arranged to releasably hold on to the garment in the first and second opened positions by stretching the cuff .
  • the elasticity of the garment is utilized for securely gripping/holding the garment, and for opening the cuff for donning .
  • the first and second insertion members are arranged to releasably hold on to the garment in first and second waiting positions by stretching the cuff, the first waiting position lying, i.e. being located, between the first centered position and the first opened position, and the second waiting position lying, i.e. being located, between the second centered position and the second opened position.
  • the elasticity of the garment is preserved. If, for example there is a longer time period, e.g. over night, when donning is not performed, the elasticity of the cuff is better kept intact if the cuff is less stretched over time in the waiting positions than it would be in the opened positions.
  • the stretching is performed without deformation of the cuff .
  • the opening mechanism in the first and second opened positions, respectively, is arranged to receive a human body part between the first and second insertion members.
  • Donning of the garment is thus facilitated by the linear movement of the first and second insertion members, such that a user may insert e.g. his hand into a glove in the space between the first and second insertion members.
  • the first and second insertion members are out of the way for a hand as the garment is donned on the hand of a user.
  • the garment is any one in the group of :
  • the need for fast and clean donning of e.g. gloves is huge in many areas, such as health care, restaurants, food stores, and the food industry.
