Definitions
- the invention relates to a device for heat shrinking by one a packaged unit shrink film according to the preamble of the claim 1.
- a device of the type mentioned above is known.
- a single heating device in the form of a height-adjustable Hot gas generator provided, which with a complete revolution around Foil wrapped batch of goods.
- a temporal overlap of the process for wrapping the piece of goods with the film and heating for Achieving shrinkage is already done within with exposure to heat of a belt sector lying between 90 ° and 270 °.
- device of the generic type for example a heating device with two opposite heating units, which a rotary movement of 180 ° around the packaged goods unit to shrink the Can run shrink wrap around the packaged goods unit.
- US-A-3 710 550 is a device for heat shrinking a film by one Packaged goods unit is known, in which several heating units are located opposite one another are provided. The heating units cover the entire area Height of the packaged goods unit. The heating units run a translatory Movement on rails.
- the invention has for its object a device for Heat shrinking from one wrapped around a packaged goods unit Provide shrink film of the generic type with which has a higher packaging performance with the lowest possible Energy requirements per shrinking process can be achieved.
- a device for heat shrinking is used for this purpose from a shrink film wrapped around a packaged goods unit provided, which is specified in claim 1.
- the heating device can by the arrangement of at least four heating units spaced apart in the circumferential direction the heating device can be achieved that at a further rotary movement of the one carrying the heating units Beam by a corresponding angular range per work step in opposite directions around the packaged goods unit placed shrink film in the intended Way through the heat of the heating units Shrinkage can be brought.
- This allows one considerable increase in device performance up to approx. 40% achieve, so that you can, for example, about 350 shrinkages per Perform hour using the device according to the invention can.
- the one required in the device according to the invention Energy expenditure is hardly appreciably greater than, for example compared to devices which are only two opposite Have warming units because the warming units at Device according to the invention much shorter than in two opposite heating units are in operation. Consequently one achieves a substantial degree in the device according to the invention higher packaging performance with almost unchanged Energy expenditure, so that the device is extremely effective To shrink the shrink film as quickly as possible can realize the packaged goods unit.
- the heating units are regular Angular distances arranged, in particular diagonally are arranged opposite one another on the carrier.
- a rotary movement around the central axis is sufficient of the beam by a partial angular range per Work out to the shrink wrap reliably around the Shrink on the packaged goods unit to secure the packaged goods.
- the carrier with the heating device is 90 ° per work step rotated.
- a first step becomes, for example, the carrier clockwise rotated by 90 ° to carry out the shrinking process, while at the execution of the shrinking process for a next packaged goods unit this then for example by 90 ° in the opposite direction means counterclockwise, back to the starting position is rotated.
- the carrier is therefore only covered by an angular range of 90 ° a reciprocating motion to then drive per Rotational motion a complete shrinking process of the shrink film complete. This will make a much higher one Shrinkage achieved, that is, significantly more Packaged goods units per unit of time treated so that the order Packaged unit shrink film placed on the same is.
- Each heating unit preferably extends in the vertical direction the packaged goods unit with shrink wrap around it.
- the heating unit is preferably formed in a strip shape and it is in particular designed as a burner strip.
- the shrink film can entire height range of the packaged goods unit when working the Heating units applied with heat as evenly as possible be, so that there is a uniform shrinking process in the Shrink wrap causes the shrink wrap to be as tight as possible adjacent to the packaged goods security to apply the packaged goods unit.
- the shrink film is preferably wrapped around the packaged goods unit Hood shape or banderole shape, in particular for securing packaged goods arranged by pallets.
- the support for the heating device is as Boom designed so that the heating units hang freely can be arranged at an angular distance on this boom.
- the packaged goods to be provided with the shrink film with the help of a suitable conveyor moved by the shrinking device according to the invention and in the same can be positioned accordingly.
- the shrink film In the device for heat shrinking from one to one it is therefore essential that the shrink film that one in a constructively simple way and without one noticeably greater energy expenditure as uniform as possible and can cause rapid shrinking of the shrink film which is placed around the packaged goods unit.
- the shortest possible route namely, for example, an angular movement by 90 °, whereby the packaging performance can be increased considerably.
- the device 1 comprises a carrier 4, which is designated as a whole by 7 Heater carries.
- the carrier 4 is in the form of a Boom 10 formed on which the individual heating units 8 are provided in a hanging arrangement.
- the warming units 8 of the heating device 7 are shown Example at regular angular intervals, i.e. in each case an angular distance of 90 ° in the circumferential direction of the carrier 4 arranged, and they extend in the height direction to one Treating packaged goods unit 2.
- a rotary drive device 5 for the carrier 4 is a ring gear 6 in the example shown shown shown which has a suitable and not in the drawing Drive device shown in detail, the carrier 4 a for example shown in Figure 2 with double arrows Rotary movement granted.
- the packaged goods unit 2 with the shrink film 3 around it which, for example, in the form of a hood or bandarole around the Packaged goods unit 2 is placed in the device 1 for heat shrinking transported and in the same with respect to the carrier 4 and the heating units 8 arranged thereon in a centered manner Form positioned.
- the carrier 4 is then by the rotary drive 5, for example, clockwise in Figure 2 when activated Heating units 8 moves so that the heat supply Heating units 8, which, for example, as burner strips 9 are designed on a rotational movement path of only 90 ° Packaged goods unit and the shrink film 3 around them evenly heat up and thus the shrink film 3 to secure the packaged goods shrink the packaged goods unit quickly and effectively.
- the Packaged goods unit 2 the shrink film 3 on the path of movement Has been shrunk 90 ° clockwise, then with With the help of the schematically shown conveyor from the Moved device 1 for heat shrinking.
- the carrier 4 by the rotary drive 5, for example in Moved counterclockwise to the starting position the shrink film 3 when the heating units 8 are activated a next packaging unit 2 in order to shrink it on completely.
- the shape of the respective heating unit 8 also deviate from that shown example can be chosen, this shape mainly depends on the outer contour of the packaged goods unit 2 is.
- the device 1 is in the Connection with a packaged goods unit 2 in the form of a pallet explained. If other packaged goods are selected, they can Heating units 8 in a corresponding manner with regard to their Shape to be matched to this. If necessary, too more than four heating units 8 arranged spaced if the packaged goods unit 2 is, for example, essential has a larger outer circumference.
