Definitions
- the invention relates to a cooling container having a removal cross-section and at least one laterally guided and displaceable cover member for closing the removal cross section, which is provided by an open position, in particular a product removal position, in which between a closure side of the cooling container or another cover member and a closure side of the cover member, a gap , in a closed position can be transferred, in which between the closure side of the cooling container or the other lid member and the closure side of the lid member substantially no gap is present, of an opening and / or opening device, an automatic closing and / or opening process introduced and after a determinable period of time either by reaching the closed position or the open position automatically terminated or counteracting by a lateral movement and a threshold exceeding force Component of an interfering force is automatically interrupted and a method for this purpose.
- Cooling container of the type mentioned are, for example, from DE 101 18 437 A1 in which the cover members of a freezer with a cable or belt system are coupled to a closing and / or opening device in the form of a drive. Also in the DE 101 18 437 A1 called are more closing and / or opening device, such as direct drives on gears or rods, friction wheels or hydraulic or pneumatic cylinders. A manual shift of the lid is the in DE 101 18 437 A1 not provided.
- a sliding lid closure in refrigerators and freezers which opens or closes the sliding cover by means of a signal initiated by a motion detector by means of a closing and / or opening device in the form of an electric motor.
- the force that is necessary to move the sliding cover is limited by a slip clutch.
- a manual shift is thereby made possible, in particular in exceptional cases, such as a power failure.
- the DE 203 08 256 U1 discloses a furniture drive for moving a furniture element wherein a anti-trap and / or the manual operability by a slip clutch is formed or guaranteed is / are.
- the object of the invention is to propose a method which makes it possible to further reduce energy consumption, to extend the life of the closing and / or opening device and to allow manually operable freezer cabinets to be equipped with an automatic closing and / or opening device.
- the object is achieved on the basis of the method of the type described above, in that a frictional connection or a positive connection between the cover member or the cooling container and the closing and / or opening device is canceled outside the period of the automatic closing and / or opening operation.
- the cover member By removing the frictional connection or the positive connection, the cover member can be moved outside the closing operation manually by a lateral movement increasing or decreasing the gap. Due to the simple manual closing and / or opening operation as a rule against the exclusively motorized displacement of the cover member, as they DE 101 18 437 A1 , the DE 43 35 458 A1 and the US Pat. No. 3,599,371 Provide considerable electricity and thus cost savings are possible. Nevertheless, manual misconduct, if advantageous, compensated to prevent a permanent open standing of the cooling tank.
- the closing and / or opening device only comes into action in comparison with the previously known cooling devices when manual operation does not take place because it is forgotten or deliberately not carried out, the operating time of the closing and / or opening device is significantly shortened, so that the service life is extended and the maintenance effort is reduced. In addition, it is perceived by the customer as pleasant to be able to perform the closing and / or opening process "fast" itself and not to have to wait for a possibly, slow automatic movement.
- the invention therefore makes parallel automatic (ie made by a drive) and the manual displacement of the cover member, the manual movement can be done by the decoupling during downtime of the closing and / or opening device with minimal effort. In any case, the overcoming of additional, caused by the closing and / or opening device frictional forces or caused by a slip resistors resistances is not necessary, so that a high ease of use exists.
- the frictional connection is defined in this context as a connection of whatever kind, which makes it possible to transmit a force.
- a frictional connection may originate for example from a friction wheel which can be driven as part of the closing and / or opening device by an electric motor.
- a direct force transmission i. an immediate adhesion, takes place approximately between the closing and / or opening device and the lid member instead.
- An indirect power transmission an indirect adhesion, in this case, between the cooling tank and the lid member.
- the closing and / or opening device may also be attached to the cover member and the direct adhesion between the closing and / or opening device and the cooling container exist.
- the positive engagement exerted by the closing and / or opening device is defined in this context as a form-fitting engagement of, for example, a toothed wheel, which is part of it the closing and / or opening device is driven by an electric motor, in a rack.
- Form-fitting connections are created by the interaction of at least two connection partners. Due to the mechanical connection, the connection partners can not be separated from each other without or with interrupted power transmission by closing and / or opening device.
- the direct positive connection exists in this case between the gear as the first connection partner and the rack as the second connection partner.
- an indirect positive connection exists, for example, between the lid member and the cooling container when, in the presence of the direct positive connection of the electric motor which drives the gear is connected to the cover member and the rack is attached to the cooling container.
- the repeal of the frictional connection or the positive connection means that the positive and non-positive connection between the connection partners is solved.
- a positive connection between the cover member or the cooling container and the closing and / or opening device outside the period of the automatic closing and / or opening operation is canceled in this case.
- only switching off the electrical energy to operate the closing and / or opening device does not necessarily mean the repeal of the frictional connection or the positive connection, since the connection between the connection partners in this case does not have to be solved. Only with the release of said connection partners from each other is a corresponding repeal. If the positive or positive connection is canceled, it is thus no longer necessary to overcome internal friction forces or moments of the closing and / or opening device manually.
- the closing device remains inactive.
- an automatic interruption of the automatic closing operation is useful when a person comes into contact with the lid member during this closing operation.
- the Störkrafterkennung can preferably be done electronically but also electro-mechanically by eg a slip clutch with signal message.
- the interruption is effected by a force component of an interfering force that counteracts the lateral movement and crosses a threshold value, which component is executed actively or passively by the person, for example.
- the period of time begins to run after a movement of the cover member, in particular when the opening movement of the cover member is stopped or interrupted, since the time for the removal or supply of products in the cooling container is then independent of the time required for the opening process time ,
- the time period can also start to run as soon as a limit switch signals that the closed position of the cover member has been left.
- An advantageous development of the invention can be achieved in that the threshold is measured substantially permanently during the automatic closing operation in order to create a timely interruption when an interference force occurs.
- the specific period of time is dependent on whether the last closing operation was completed or interrupted.
- the specific time span can be extended, for example if the last closing operation was automatically interrupted and there is the (slight) danger that a person with his or her hand or arm will still be inside the cooling container, at least for a statistically ascertainable mean time span and should continue to ensure that this person has removed at the end of the certain period of statistically determinable probability of the cooling tank.
- a shorter period of time may be set until the closing operation is initiated.
- the period of time can be preselected by means of a conventional time switching element or by means of a programmable microcontroller, with the latter being able to fulfill a large number of further functions for control and monitoring.
- the force component can be determined by measuring a-taken from a drive device current, creating a particularly easy to implement, yet sufficiently sensitive way is created to detect the disturbance force.
- the method can be further developed in that the threshold value of the force component of the disturbing force, which triggers the interruption, in particular at a first commissioning of the closing and / or opening device, by means of at least one metrological detection of a voltage and / or a current during the non-interfering automatic Closing and / or opening operation and upon reaching the closed position or open position and programmatically determined. Due to the automatic determination of the threshold value, differently powerful closing and / or opening device can be switched off with a determinable disturbance force. A calibration of the closing and / or opening device by qualified personnel can be omitted, so that the installation can be made in principle by auxiliary staff.
- the object of the invention is also to propose a cooling container, which makes it possible to apply the method described.
- the object is achieved by a cooling container, wherein it is provided that a frictional connection or a positive connection between the cover member or the cooling container and the closing and / or opening device outside the period des.automatische closing and / or opening operation can be canceled.
- the advantages of the cooling tank correspond to those of the process.
- the closing device can be switched off by a switch, such as when during a longer-lasting filling or defrosting the removal section should remain in the open position for a long time.
- a further development also provides that a carrier element can be fastened to the lid member and laterally, in particular linear-laterally, relative to the cooling container, which additionally can be folded up and / or hinged by means of a hinge to the respective lid members, in particular their gripping elements ,
- the invention may also be developed in that a drive element of a drive device can be transferred from a release position in which it is out of engagement with a guide device into an engagement position in which it engages with the guide device.
- the drive device is fixedly secured to the cooling container and the guide device to the cover member, but it is alternatively preferred that the guide means is fixedly secured to the cooling container and the drive means to the lid member.
- the drive element can be transferred by means of a positioning element of a setting device between the release position and the engagement position, since the coupling and decoupling can be automated particularly easily by means of a positioning element.
- the switch position By the switch position, the instantaneous position of the drive device is always queried in a very simple manner and can be easily interrogated, such as by an electronic comparison circuit. That two switching states are indicated by the switch position, is usually completely sufficient.
- the switch can be used to switch the supply current, for example for the drive device or for Anstellantrieb the Anstellelementes, for example, by the drive device drives only the drive element when the switch is no longer in the switch position corresponding to the release position.
- the positioning element is movable by means of a Anstellantriebs the drive device, wherein it is preferred if the Anstellantrieb is a servo device with a drive pulley with eccentrically arranged pin which engages in a slot in the Anstellelement, since such a servo device represents cheap bulk commodity that has been used for many years in model making.
- the closing device has a carriage device which can be moved along the guide element and which can be coupled to the cover element, in particular by means of the driving element.
- a movable carriage device on the one hand, only the length of the guide element, which may be designed as a rack, for example, and on the other hand, the entrainment be adapted to the respective cooling tank.
- a development of the invention also provides that a limit switch is attached to the cooling container or the closing device, which is actuated in the closed position by the carriage device and / or the lid member and the closing position for a shutdown of the power supply to the drive device in a particularly simple manner can use.
- the carriage device can be supplied with electrical energy by means of at least one supply line, wherein the supply line is guided by means of an energy guiding device, in particular an energy chain consisting of a plurality of chain links.
- energy chains are a bulk material and are correspondingly inexpensive to obtain , They generally allow a systematic, simple, safe and yet movable laying of cables.
- cooling container has two superimposed sliding cover members, which are each provided with a carriage means, whereby they can move independently and which are connected to one end of a common and thus efficiently used energy management device and also for both carriage devices a common guide rail and a common guide member is provided, wherein the guide rail and the guide member are connected to each other connectable or integral.
- the closing device can be covered by a cover, to which information and / or advertising elements or lighting devices can be attached.
- a cover to which information and / or advertising elements or lighting devices can be attached.
- the advantageous closing and / or opening device can be used advantageously not only for cooling containers, but also for uncooled goods display furniture or similar devices.
- the skilled person will also be able to easily transfer the advantages mentioned from cover organs to other closure organs such as sliding doors.
- hydraulic components for the closing and / or opening device can be used without departing from the scope of the invention. So it would be conceivable in principle to equip a hydraulic cylinder with a controllable solenoid valve, which can switch the hydraulic cylinder without pressure and so could lift a frictional connection.

- the energy management device 2220, the guide device 2300 and the cover 2400 are shown separated from the remaining elements of the closure device 2000 for a better overview.
- the closing device 2000 does not increase the occupied base area of the cooling container 1000, so that two cooling containers 1000 with closure device 2000 can also be set flush with their backs not visible here, for example for improved or unchanged good utilization of space in central aisles in supermarkets.
- Fig. 2 shows the cooling tank 1000 according to Fig. 1 , but partly in an open position O, namely that of the first (left) lid member 1200.

- the second carriage device 2200 ' which is coupled to the second (right) lid member 1200' by means of the second entrainment member 2210 ', is still in the closed position S, as she was already in Fig. 1 is shown.
- the energy guiding device 2220 is adapted to the new position of the carriage device 2200 such that the circumferential left-hand loop 2223 is approximately between the left first and second quarters of the guide device 2300 when reaching the center position of the carriage device 2200.
- the power management device 2220, the guide device 2300, and the cover 2400 are shown separated from the remaining elements of the closure device 2000 for the sake of clarity.
- the Fig. 3 shows in detail and enlarges the carriage device 2200; the (briefly shown) guide device 2300 and the (also shown shortened) power supply device 2220 with their individual chain links 2222nd
- the carriage apparatus 2200 runs by means of four plastic sliding or ball bearing guide wheels 2201-2204 in an upper and lower profile groove 2321, 2322 of an aluminum guide rail 2320 of the guide device 2300, each guide wheel 2201-2204 having a projecting collar 2201'-2204 ', with which it engages in the profile grooves 2321, 2322, respectively.
- the guide wheels 2201-2204 are made by means of screws 2201 "-2204" and tubular spacers 2211-2214 made of steel, which are in Fig. 6 and Fig. 7 are shown attached to a retaining plate 2230.
- the driving element 2210 is fastened to the retaining plate 2230 in the form of a control and regulating electronics.
- the drive device 2240 is shown in a release position F, in which a drive element 2241 in the form of a gear is spaced from a guide element 2340 of the guide device 2300 in the form of a rack made of steel or plastic.
- the immediate one Positive fit which otherwise exists between the gear as the first connection partner and the rack as the second connection partner, is released in the release position F.

- the recorded drive current of the drive 2243 increased by several to a few hundred milli - or microamps. If this increase in current exceeds the preset threshold value, the setting element 2251 with the drive 2243 fastened to it is immediately returned to the release position and, at the same time, the power supply to the drive 2243 is interrupted. In this case, optionally an interrupt signal can be output by suitable signaling means.
- the automatic closing operation described above is continued until the closed position S is reached.
- the actuation of the limit switch 2280 by the switching angle 2350 indicates to the control and regulating device 2265 the proper reaching of the closed position.

Insbesondere findet der automatische Schließvorgang oder Öffnungsvorgang nur statt, wenn eine Fehlbedienung stattgefunden hat, d.h. wenn z. B eine Person, die dem Innenraum des Kühlbehälters ein Produkt entnommen oder zugeführt hat, das Deckelorgan nach Entnahme bzw. Zuführung innerhalb der bestimmten Zeitspanne nicht oder nicht vollständig in eine Schließstellung überführt hat.It is thus generally known to automatically close or open a cover member of a cooling container from an open position after a, in particular short, adjustable period of time, wherein a necessary for the formation of ice and the resulting disadvantages air exchange can take place only in much shorter periods. In particular, the automatic closing or opening operation takes place only when a misoperation has taken place, i. if z. B a person who has removed or supplied a product to the interior of the cooling container, the lid member after removal or delivery within the specified period of time has not or not completely transferred to a closed position.
Obwohl der automatische Schließ- und/oder Öffnungsvorgang der genannten Schließ- und Öffnungsvorrichtungen zum geringeren Energieverbrauch beitragen soll, vor allem, um manuelle Fehlbedienung, etwa ein versehentliches Offenlassen des Entnahmequerschnitts, von vorneherein auszuschließen, ist zunächst offensichtlich, dass zunächst mehr elektrische Energie für den automatische Schließ- und/oder Öffnungsvorgang selbst verbraucht wird.Although the automatic closing and / or opening operation of the said closing and opening devices to contribute to lower energy consumption, especially to manual misoperation, such as accidentally leaving the unloading cross-section excluded from the outset, it is first obvious that initially more electrical energy for the automatic closing and / or opening process itself is consumed.
Aufgabe der Erfindung ist es ein Verfahren vorzuschlagen, das es ermöglicht, weiter den Energieverbrauch zu senken, die Lebensdauer der Schließ- und/oder Öffnungsvorrichtung zu verlängern und es zu erlauben, manuell betätigbare Kühltruhen mit einer automatischen Schließ- und/oder Öffnungsvorrichtung auszustatten.The object of the invention is to propose a method which makes it possible to further reduce energy consumption, to extend the life of the closing and / or opening device and to allow manually operable freezer cabinets to be equipped with an automatic closing and / or opening device.
Die Aufgabe wird, ausgehend von dem Verfahren der Eingangs beschriebenen Art, dadurch gelöst, dass ein Kraftschluss oder ein Formschluss zwischen dem Deckelorgan oder dem Kühlbehälter und der Schließ- und/oder Öffnungsvorrichtung außerhalb des Zeitraums des automatischen Schließ- und/oder Öffnungsvorgangs aufgehoben wird.The object is achieved on the basis of the method of the type described above, in that a frictional connection or a positive connection between the cover member or the cooling container and the closing and / or opening device is canceled outside the period of the automatic closing and / or opening operation.
Durch die Aufhebung des Kraftschlusses oder des Formschlusses kann das Deckelorgan außerhalb des Schließvorgangs manuell durch eine den Zwischenraum vergrößernde oder verkleinernde Lateralbewegung verschoben werden. Durch den einfachen manuellen Schließ- und/oder Öffnungsvorgang als Regelfall gegenüber der ausschließlich motorischen Verschiebung des Deckelorgans, wie sie die
Der Kraftschluss wird in diesem Zusammenhang definiert als eine wie auch immer geartete Verbindung, die es ermöglicht, eine Kraft zu übertragen. Ein derartiger Kraftschluss kann etwa von einem Reibrad ausgehen, das als Teil der Schließ- und/oder Öffnungsvorrichtung von einem Elektromotor antreibbar ist. Eine direkte Kraftübertragung, d.h. ein unmittelbarer Kraftschluss, findet etwa zwischen der Schließ- und/oder Öffnungsvorrichtung und dem Deckelorgan, statt. Eine indirekte Kraftübertragung, ein mittelbarer Kraftschluss, besteht in diesem Fall zwischen dem Kühlbehälter und dem Deckelorgan. Alternativ kann die Schließ- und/oder Öffnungsvorrichtung auch an dem Deckelorgan befestigt sein und der unmittelbare Kraftschluss zwischen der Schließ- und/öder Öffnungsvorrichtung und dem Kühlbehälter bestehen.The frictional connection is defined in this context as a connection of whatever kind, which makes it possible to transmit a force. Such a frictional connection may originate for example from a friction wheel which can be driven as part of the closing and / or opening device by an electric motor. A direct force transmission, i. an immediate adhesion, takes place approximately between the closing and / or opening device and the lid member instead. An indirect power transmission, an indirect adhesion, in this case, between the cooling tank and the lid member. Alternatively, the closing and / or opening device may also be attached to the cover member and the direct adhesion between the closing and / or opening device and the cooling container exist.
Der von der Schließ- und/oder Öffnungsvorrichtung ausgeübte Formschluss wird in diesem Zusammenhang definiert als ein formschlüssiger Eingriff etwa eines Zahnrades, das als Teil der Schließ- und/oder Öffnungsvorrichtung von einem Elektromotor antreibbar ist, in eine Zahnstange. Formschlüssige Verbindungen entstehen durch das Ineinandergreifen von mindestens zwei Verbindungspartnern. Durch die mechanische Verbindung können sich die Verbindungspartner auch ohne oder bei unterbrochener Kraftübertragung durch Schließ- und/oder Öffnungsvorrichtung nicht voneinander lösen. Der unmittelbare Formschluss besteht in diesem Fall zwischen dem Zahnrad als erstem Verbindungspartner und der Zahnstange als zweitem Verbindungspartner. Ein mittelbarer Formschluss besteht jedoch beispielsweise dann zwischen dem Deckelorgan und dem Kühlbehälter, wenn bei Vorliegen des unmittelbaren Formschlusses der Elektromotor, der das Zahnrad antreibt, mit dem Deckelorgan verbunden ist und die Zahnstange an dem Kühlbehälter angebracht ist.The positive engagement exerted by the closing and / or opening device is defined in this context as a form-fitting engagement of, for example, a toothed wheel, which is part of it the closing and / or opening device is driven by an electric motor, in a rack. Form-fitting connections are created by the interaction of at least two connection partners. Due to the mechanical connection, the connection partners can not be separated from each other without or with interrupted power transmission by closing and / or opening device. The direct positive connection exists in this case between the gear as the first connection partner and the rack as the second connection partner. However, an indirect positive connection exists, for example, between the lid member and the cooling container when, in the presence of the direct positive connection of the electric motor which drives the gear is connected to the cover member and the rack is attached to the cooling container.
Die Aufhebung des Kraftschlusses oder des Formschlusses bedeutet, das die formschlüssige und kraftschlüssige Verbindung zwischen den Verbindungspartnern gelöst ist. Ein Formschluss zwischen dem Deckelorgan oder dem Kühlbehälter und der Schließ- und/oder Öffnungsvorrichtung außerhalb des Zeitraums des automatischen Schließ- und/oder Öffnungsvorgangs ist in diesem Fall aufgehoben. In diesem Zusammenhang wird deutlich, dass allein das Abschalten der elektrischen Energie zum Betrieb der Schließ- und/oder Öffnungsvorrichtung nicht notwendig die Aufhebung des Kraftschlusses oder des Formschlusses bedeutet, da die Verbindung zwischen den Verbindungspartnern in diesem Fall nicht gelöst sein muss. Erst mit Lösen der genannten Verbindungspartner voneinander liegt eine entsprechende Aufhebung vor. Wenn der Kraft- oder Formschluss aufgehoben ist, ist es somit nicht mehr erforderlich, innere Reibkräfte oder -momente der Schließ- und/oder Öffnungsvorrichtung manuell überwinden zu müssen.The repeal of the frictional connection or the positive connection means that the positive and non-positive connection between the connection partners is solved. A positive connection between the cover member or the cooling container and the closing and / or opening device outside the period of the automatic closing and / or opening operation is canceled in this case. In this context, it is clear that only switching off the electrical energy to operate the closing and / or opening device does not necessarily mean the repeal of the frictional connection or the positive connection, since the connection between the connection partners in this case does not have to be solved. Only with the release of said connection partners from each other is a corresponding repeal. If the positive or positive connection is canceled, it is thus no longer necessary to overcome internal friction forces or moments of the closing and / or opening device manually.
Solange die Schließstellung des Deckelorgans durch manuelle Betätigung innerhalb der einstellbaren Zeitspanne erreicht wird, bleibt die Schließvorrichtung inaktiv. Während des Schließvorgangs ist eine automatische Unterbrechung des automatischen Schließvorgangs sinnvoll, wenn eine Person mit dem Deckelorgan während dieses Schließvorgangs in Kontakt kommt. Insbesondere kann durch die automatische Unterbrechung des automatischen Schließvorgangs ein Einquetschen von Hand oder Arm der Person zwischen Verschlussseite des Kühlbehälters oder eines weiteren Deckelorgans und einer Verschlussseite des Deckelorgans völlig ausgeschlossen werden. Die Störkrafterkennung kann vorzugsweise elektronisch aber auch elektro-mechanisch durch z.B. eine Rutschkupplung mit Signalmeldung erfolgen.As long as the closed position of the lid member is achieved by manual operation within the adjustable period of time, the closing device remains inactive. During the closing process, an automatic interruption of the automatic closing operation is useful when a person comes into contact with the lid member during this closing operation. In particular, can be completely excluded by the automatic interruption of the automatic closing a pinching of the person's hand or arm between the closure side of the cooling container or another lid member and a closure side of the lid member. The Störkrafterkennung can preferably be done electronically but also electro-mechanically by eg a slip clutch with signal message.
Die Unterbrechung geschieht durch eine der Lateralbewegung entgegenwirkende und einen Schwellenwert überschreitende Kraftkomponente einer Störkraft, die beispielsweise von der Person aktiv oder passiv ausgeführt wird.The interruption is effected by a force component of an interfering force that counteracts the lateral movement and crosses a threshold value, which component is executed actively or passively by the person, for example.
Vorteilhafterweise beginnt die Zeitspanne nach einer Bewegung des Deckelorgans zu laufen, insbesondere wenn die Öffnungsbewegung des Deckelorgans beendet bzw. unterbrochen wird, da die Zeit, die zur Entnahme bzw. Zufuhr von Produkten in den Kühlbehälter dann unabhängig von der für den Öffnungsvorgang benötigten- Zeit ist. Alternativ kann die Zeitspanne auch zu laufen beginnen, sobald ein Endschalter signalisiert, dass die Schließposition des Deckelorgans verlassen wurde.Advantageously, the period of time begins to run after a movement of the cover member, in particular when the opening movement of the cover member is stopped or interrupted, since the time for the removal or supply of products in the cooling container is then independent of the time required for the opening process time , Alternatively, the time period can also start to run as soon as a limit switch signals that the closed position of the cover member has been left.
Eine vorteilhafte Weiterbildung der Erfindung kann dadurch erreicht werden, dass der Schwellenwert im wesentlichen permanent während des automatischen Schließvorgangs gemessen wird, um eine möglichst zeitnahe Unterbrechung bei Auftreten einer Störkraft zu schaffen.An advantageous development of the invention can be achieved in that the threshold is measured substantially permanently during the automatic closing operation in order to create a timely interruption when an interference force occurs.
Ein weiterer Vorteil kann dadurch erreicht werden, dass die bestimmte Zeitspanne davon abhängig ist, ob der zuletzt durchgeführte Schließvorgang beendet oder unterbrochen wurde. So kann aufgrund von Sicherheitsüberlegungen die bestimmte Zeitspanne verlängert werden, etwa wenn der letzte Schließvorgang automatisch unterbrochen wurde und somit zumindest für eine statistisch ermittelbare mittlere Zeitspanne die (geringe) Gefahr besteht, dass sich eine Person mit ihrer Hand oder ihrem Arm noch im Innenbereich des Kühlbehälters befindet und weiterhin sichergestellt sein soll, dass sich diese Person nach Ablauf der bestimmten Zeitspanne mit statistisch bestimmbarer Wahrscheinlichkeit von dem Kühlbehälter entfernt hat. Falls der letzte Schließvorgang allerdings manuell oder automatisch beendet wurde, kann eine kürzer bestimmte Zeitspanne bis zur Einleitung des Schließvorgangs eingestellt werden. Die Zeitspanne kann mittels eines herkömmlichen Zeitschaltelementes oder mittels eines programmierbaren Mikrocontrollers vorgewählt werden, wobei bei letzterem eine Vielzahl weiterer Funktionen zur Steuerung und Überwachung erfüllt werden können.Another advantage can be achieved by the fact that the specific period of time is dependent on whether the last closing operation was completed or interrupted. Thus, due to safety considerations, the specific time span can be extended, for example if the last closing operation was automatically interrupted and there is the (slight) danger that a person with his or her hand or arm will still be inside the cooling container, at least for a statistically ascertainable mean time span and should continue to ensure that this person has removed at the end of the certain period of statistically determinable probability of the cooling tank. However, if the last closing operation has been completed manually or automatically, a shorter period of time may be set until the closing operation is initiated. The period of time can be preselected by means of a conventional time switching element or by means of a programmable microcontroller, with the latter being able to fulfill a large number of further functions for control and monitoring.
Gemäß einer Weiterbildung der Erfindung kann die Kraftkomponente mittels Messung eines -von einer Antriebsvorrichtung aufgenommenen Stroms ermittelt werden, wodurch eine besonders einfach zu realisierende und dennoch genügend sensitive Möglichkeit geschaffen wird, die Störkraft zu detektieren.According to one embodiment of the invention, the force component can be determined by measuring a-taken from a drive device current, creating a particularly easy to implement, yet sufficiently sensitive way is created to detect the disturbance force.
Schließlich kann das Verfahren dadurch weitergebildet werden, dass der Schwellenwert der Kraftkomponente der Störkraft, der die Unterbrechung auslöst, insbesondere bei einem erstmaligen Inbetriebnehmen der Schließ- und/oder Öffnungsvorrichtung, mittels mindestens eines messtechnischen Erfassens einer Spannung und/oder eines Stromes während des störkraftfreien automatischen Schließ- und/oder Öffnungsvorgangs und bei einem Erreichens der Schließstellung oder Offenstellung und programmtechnisch ermittelt wird.
Durch die automatische Ermittlung des Schwellenwertes können auch unterschiedlich leistungsfähige Schließ- und/oder Öffnungsvorrichtung bei einer bestimmbaren Störkraft abgeschaltet werden. Eine Kalibrierung der Schließ- und/oder Öffnungsvorrichtung durch Fachpersonal kann damit entfallen, so dass die Installation grundsätzlich auch von Hilfspersonal vorgenommen werden kann.Finally, the method can be further developed in that the threshold value of the force component of the disturbing force, which triggers the interruption, in particular at a first commissioning of the closing and / or opening device, by means of at least one metrological detection of a voltage and / or a current during the non-interfering automatic Closing and / or opening operation and upon reaching the closed position or open position and programmatically determined.
Due to the automatic determination of the threshold value, differently powerful closing and / or opening device can be switched off with a determinable disturbance force. A calibration of the closing and / or opening device by qualified personnel can be omitted, so that the installation can be made in principle by auxiliary staff.
Aufgabe der Erfindung ist es ebenfalls ein Kühlbehälter vorzuschlagen, der es ermöglicht, das beschriebene Verfahren anzuwenden.The object of the invention is also to propose a cooling container, which makes it possible to apply the method described.
Die Aufgabe wird durch einen Kühlbehälter gelöst, bei dem vorgesehen ist, dass ein Kraftschluss oder ein Formschluss zwischen dem Deckelorgan oder dem Kühlbehälter und der Schließ- und/oder Öffnungsvorrichtung außerhalb des Zeitraums des.automatischen Schließ- und/oder Öffnungsvorgangs aufhebbar ist. Die Vorteile des Kühlbehälters entsprechen denen des Verfahrens.The object is achieved by a cooling container, wherein it is provided that a frictional connection or a positive connection between the cover member or the cooling container and the closing and / or opening device outside the period des.automatische closing and / or opening operation can be canceled. The advantages of the cooling tank correspond to those of the process.
Gemäß einer Weiterbildung der Erfindung kann die Schließvorrichtung durch einen Schalter abschaltbar sein, etwa wenn während eines länger andauernden Befüll- oder Abtauvorgangs die Entnahmequerschnitt für längere Zeit in Offenstellung bleiben soll.According to one embodiment of the invention, the closing device can be switched off by a switch, such as when during a longer-lasting filling or defrosting the removal section should remain in the open position for a long time.
Eine Weiterbildung sieht zudem vor, dass ein Mitnahmeelement an dem Deckelorgan befestigbar und von der Schließvorrichtung lateral, insbesondere linear-lateral, relativ zum Kühlbehälter bewegbar ist, welches zusätzlich noch den jeweiligen Deckelorganen, insbesondere deren Griffelementen, anpassbar und/oder mittels eines Scharniers hochklappbar ist.A further development also provides that a carrier element can be fastened to the lid member and laterally, in particular linear-laterally, relative to the cooling container, which additionally can be folded up and / or hinged by means of a hinge to the respective lid members, in particular their gripping elements ,
Die Erfindung kann ebenfalls dadurch weitergebildet werden, dass ein Antriebselement einer Antriebsvorrichtung von einer Freigabestellung, in der es außer Eingriff mit einer Führungseinrichtung ist, in eine Eingriffstellung überführbar ist, in der es mit der Führungseinrichtung in Eingriff ist. Durch die Kopplung und Entkopplung der Antriebsvorrichtung mit der Führungseinrichtung kann erreicht werden, dass ein manuelles Öffnen und Schließen des Kühlbehälters außerhalb des Schließvorgangs, also während der Entkopplung, ohne besondere Kraft vonstatten gehen kann.The invention may also be developed in that a drive element of a drive device can be transferred from a release position in which it is out of engagement with a guide device into an engagement position in which it engages with the guide device. By the coupling and decoupling of the drive device with the guide device can be achieved that a manual opening and closing of the cooling tank outside of the closing process, ie during decoupling, can go without special force.
Ebenfalls eine Weiterbildung ist es, dass die Antriebsvorrichtung fest an dem Kühlbehälter und die Führungseinrichtung an dem Deckelorgan befestigt ist, allerdings wird alternativ bevorzugt, dass die Führungseinrichtung fest an dem Kühlbehälter und die Antriebseinrichtung an dem Deckelorgan befestigt ist.Another development is that the drive device is fixedly secured to the cooling container and the guide device to the cover member, but it is alternatively preferred that the guide means is fixedly secured to the cooling container and the drive means to the lid member.
Es wurde weiterhin gefunden, dass das Antriebselement mittels eines Anstellelements einer Anstellvorrichtung zwischen der Freigabestellung und der Eingriffstellung überführbar ist, da sich die Kopplung und Entkopplung mittels eines Anstellelementes besonders einfach automatisieren lässt.It has also been found that the drive element can be transferred by means of a positioning element of a setting device between the release position and the engagement position, since the coupling and decoupling can be automated particularly easily by means of a positioning element.
Es ist für bestimmte Anwendungen besonders vorteilhaft, wenn ein Schalter in der Freigabestellung von der Antriebsvorrichtung und/oder dem Anstellelement betätigbar ist. Durch die Schalterstellung wird stets auf äußerst einfache Weise die momentane Stellung der Antriebsvorrichtung abfragbar gehalten und kann leicht , etwa von einer elektronischen Vergleichsschaltung, abgefragt werden. Dass zwei Schaltzustände durch die Schalterstellung angegeben werden, ist zumeist völlig ausreichend. Zudem kann der Schalter zur Schaltung des Versorgungsstroms, etwa für die Antriebsvorrichtung oder für einen Anstellantrieb des Anstellelementes genutzt werden, indem beispielsweise die Antriebsvorrichtung nur das Antriebselement antreibt, wenn sich der Schalter nicht mehr in der zur Freigabestellung entsprechenden Schalterstellung befindet.It is particularly advantageous for certain applications when a switch in the release position of the drive device and / or the adjusting element is actuated. By the switch position, the instantaneous position of the drive device is always queried in a very simple manner and can be easily interrogated, such as by an electronic comparison circuit. That two switching states are indicated by the switch position, is usually completely sufficient. In addition, the switch can be used to switch the supply current, for example for the drive device or for Anstellantrieb the Anstellelementes, for example, by the drive device drives only the drive element when the switch is no longer in the switch position corresponding to the release position.
Von besonderem Vorteil ist es, wenn das Anstellelement mittels eines Anstellantriebs der Antriebsvorrichtung bewegbar ist, wobei es bevorzugt wird, wenn der Anstellantrieb eine Servoeinrichtung mit einer Antriebsscheibe mit exzentrisch angeordnetem Zapfen ist, der in ein Langloch in dem Anstellelement eingreift, da eine derartige Servoeinrichtung ein günstig einkaufbares Massenprodukt darstellt, das schon viele Jahre im Modellbau angewendet wird.It is particularly advantageous if the positioning element is movable by means of a Anstellantriebs the drive device, wherein it is preferred if the Anstellantrieb is a servo device with a drive pulley with eccentrically arranged pin which engages in a slot in the Anstellelement, since such a servo device represents cheap bulk commodity that has been used for many years in model making.
Eine weitere Weiterbildung der Erfindung ist es, dass die Schließvorrichtung eine entlang des Führungselementes bewegbare Wagenvorrichtung aufweist, die mit dem Deckelorgan, insbesondere mittels des Mitnahmeelementes, koppelbar ist. Durch die Verwendung einer bewegbaren-Wagenvorrichtung muss einerseits nur noch die Länge des Führungselementes, welches etwa als Zahnstange ausgebildet sein kann, und andererseits das Mitnahmeelement an den jeweiligen Kühlbehälter angepasst werden. Durch diese leicht und kostengünstig zu vollziehende Anpassung kann im Grunde dieselbe Schließvorrichtung für die meisten Kühlbehälter verwendet werden. Auch eine Nachrüstung bereits vorhandener Kühlbehälter ist so sehr einfach möglich.A further development of the invention is that the closing device has a carriage device which can be moved along the guide element and which can be coupled to the cover element, in particular by means of the driving element. By using a movable carriage device on the one hand, only the length of the guide element, which may be designed as a rack, for example, and on the other hand, the entrainment be adapted to the respective cooling tank. By this easy and inexpensive to perform adaptation basically the same closing device can be used for most cooling containers. A retrofit already existing cooling tank is very easy.
Eine Weiterbildung der Erfindung sieht zudem vor, dass ein Endschalter an dem Kühlbehälter oder der Schließvorrichtung befestigt ist, der in der Schließstellung durch die Wagenvorrichtung und/oder das Deckelorgan betätigt ist und der auf besonders einfache Weise die Schließstellung für eine Abschaltung der Stromzufuhr zu der Antriebseinrichtung nutzen kann.A development of the invention also provides that a limit switch is attached to the cooling container or the closing device, which is actuated in the closed position by the carriage device and / or the lid member and the closing position for a shutdown of the power supply to the drive device in a particularly simple manner can use.
Eine Weiterbildung der Erfindung wird dadurch erreicht, dass die Wagenvorrichtung mittels mindestens einer Versorgungsleitung mit elektrischer Energie versorgbar ist, wobei die Versorgungsleitung mittels einer Energieführungseinrichtung, insbesondere einer Energiekette, bestehend aus einer Mehrzahl von Kettengliedern, geführt ist Energieketten sind ein Massengut und entsprechend günstig zu beziehen. Sie erlauben generell eine systematische, einfache, sichere und dennoch bewegbare Verlegung von Leitungen.A further development of the invention is achieved in that the carriage device can be supplied with electrical energy by means of at least one supply line, wherein the supply line is guided by means of an energy guiding device, in particular an energy chain consisting of a plurality of chain links. Energy chains are a bulk material and are correspondingly inexpensive to obtain , They generally allow a systematic, simple, safe and yet movable laying of cables.
Eine Weiterbildung der Erfindung wird zudem dadurch erreicht, dass der Kühlbehälter zwei übereinander schiebbare Deckelorgane aufweist, die jeweils mit einer Wageneinrichtung versehen sind, wodurch sie sich unabhängig voneinander bewegen lassen und die mit einem Ende einer gemeinsamen und damit effizient genutzten Energieführungseinrichtung verbunden sind und zudem für beide Wageneinrichtungen eine gemeinsame Führungsschiene und ein gemeinsames Führungselement vorgesehen ist, wobei die Führungsschiene und das Führungselement miteinander verbindbar oder einstückig ausgeführt sind.A development of the invention is also achieved in that the cooling container has two superimposed sliding cover members, which are each provided with a carriage means, whereby they can move independently and which are connected to one end of a common and thus efficiently used energy management device and also for both carriage devices a common guide rail and a common guide member is provided, wherein the guide rail and the guide member are connected to each other connectable or integral.
Schließlich soll die Erfindung dadurch weitergebildet werden, dass die Schließvorrichtung durch eine Abdeckung abdeckbar ist, woran Informations- und/oder Werbeelemente oder Beleuchtungseinrichtungen anbringbar sind. Der Vorteil ist insbesondere darin zu sehen, dass schon bei bekannten Kühlbehältern, insbesondere in Supermärkten, Informations- und/oder Werbeelemente in Form von Preisauszeichnungen und anpreisenden Beschreibungen der Produkte oft auf eigenen Aufbaukörpern angebracht sind, und dass somit durch die Verwendung einer Abdeckung nicht nur die sonstigen Elemente der Schließvorrichtung vor Verunreinigung geschützt werden, sondern im Grunde auch kein zusätzlicher Platz benötigt wird, da man sich bei Aufrüstung von herkömmlichen Supermarkt-Kühlbehältern mit der erfindungsgemäßen Schließvorrichtung der genannten Aufbaukörper sinnvoll entledigen kann.Finally, the invention should be further developed in that the closing device can be covered by a cover, to which information and / or advertising elements or lighting devices can be attached. The advantage is in particular to be seen in the fact that already in known refrigerated containers, especially in supermarkets, information and / or advertising elements in the form of price awards and promotional descriptions of the products are often mounted on their own bodies body, and thus by the use of a cover not only the other elements of the closure device from contamination be protected, but basically no additional space is needed because you can get rid of upgrading conventional supermarket refrigerated containers with the locking device according to the invention said body structure meaningful.
Selbstverständlich kann die vorteilhafte Schließ- und/oder Öffnungsvorrichtung nicht nur für Kühlbehälter vorteilhaft eingesetzt werden, sondern auch für ungekühlte Warenpräsentationsmöbel oder ähnliche Geräte. Der Fachmann wird die genannten Vorteile auch leicht von Deckelorganen auf weitere Verschlussorgane etwa Schiebetüren übertragen können. Im Übrigen können anstelle oder zusätzlich zu den bevorzugten elektrischen und elektromechanischen Komponenten beispielsweise auch hydraulische Komponenten für die Schließ- und/oder Öffnungsvorrichtung verwendet werden, ohne den Bereich der Erfindung zu verlassen. So wäre es grundsätzlich denkbar einen Hydraulikzylinder mit einem ansteuerbaren Magnetventil auszustatten, das den Hydraulikzylinder drucklos schaltet kann und so einen Kraftschluß aufheben könnte.Of course, the advantageous closing and / or opening device can be used advantageously not only for cooling containers, but also for uncooled goods display furniture or similar devices. The skilled person will also be able to easily transfer the advantages mentioned from cover organs to other closure organs such as sliding doors. Incidentally, instead of or in addition to the preferred electrical and electromechanical components, for example, hydraulic components for the closing and / or opening device can be used without departing from the scope of the invention. So it would be conceivable in principle to equip a hydraulic cylinder with a controllable solenoid valve, which can switch the hydraulic cylinder without pressure and so could lift a frictional connection.

Ebenfalls gezeigt ist eine Schließvorrichtung 2000, die zwei Wagenvorrichtungen 2200, 2200' mit Abdeckhauben 2299, 2299' aufweist. Die Wagenvorrichtungen 2200, 2200' sind entlang einer Führungseinrichtung 2300 bewegbar geführt. Die Stromversorgung der beiden Wagenvorrichtungen 2200, 2200' findet über hier nicht gezeigte Versorgungsleitungen statt, die in einer Energieführungseinrichtung 2220 in Form einer sogenannten Energiekette mit einer Mehrzahl von Kettengliedern 2222 gelagert sind. Die gesamte Schließvorrichtung 2000 ist von einer Abdeckung 2400 abgedeckt. Die Abdeckung 2400 weist auf einer Informations- und Werbefläche 2420, die in einem Winkel von etwa 100 Grad zu den Grundflächen der Deckelorgane 1200, 1200' angeschrägt ist, einen Schalter 2500 in Form eines Drehschalters auf, mit dem die gesamte Stromzufuhr für die Schließvorrichtung 2000 unterbrechbar ist. Die Energieführungseinrichtung 2220, die Führungseinrichtung 2300 sowie die Abdeckung 2400 sind von den restlichen Elementen der Schließvorrichtung 2000 wegen einer besseren Übersicht getrennt gezeigt. Die Schließvorrichtung 2000 vergrößert im übrigen die eingenommene Grundfläche des Kühlbehälters 1000 nicht, so dass auch zwei Kühlbehälter 1000 mit Schließvorrichtung 2000 mit ihren hier nicht sichtbaren Rückseiten einander bündig aufgestellt werden können, etwa zwecks verbesserter oder unverändert guter Raumausnutzung bei Mittelgängen in Supermärkten.Also shown is a closure device 2000 having two

Die Wagenvorrichtung 2200 läuft mittels vier gleit- oder kugelgelagerten Führungsrädern 2201-2204 aus Kunststoff in einer oberen und unteren Profilnut 2321, 2322 einer Führungsschiene 2320 aus Aluminium der Führungseinrichtung 2300, wobei jedes Führungsrad 2201-2204 einen vorstehenden Bund 2201'-2204' aufweist, mit dem es jeweils in die Profilnuten 2321, 2322 eingreift. Die Führungsräder 2201-2204 sind mittels Schrauben 2201"-2204" und rohrförmigen Distanzelementen 2211-2214 aus Stahl, die in
Ebenfalls am Halteblech 2230 befestigt ist das Mitnahmeelement 2210, eine Antriebsvorrichtung 2240, eine Anstellvorrichtung 2250 und eine in einem Kunststoffgehäuse 2260 eingefassten Steuer- und Regelvorrichtung 2265 in Form einer Steuer- und Regelelektronik. Die Antriebsvorrichtung 2240 ist in einer Freigabestellung F gezeigt, bei der ein Antriebselement 2241 in Form eines Zahnrades von einem Führungselement 2340 der Führungseinrichtung 2300 in Form einer Zahnstange aus Stahl oder Kunststoff beabstandet ist. Der unmittelbare Formschluss, der ansonsten zwischen dem Zahnrad als erstem Verbindungspartner und der Zahnstange als zweitem Verbindungspartner besteht, ist in der Freigabestellung F aufgehoben. Das Antriebselement 2241 ist mit einer Motorwelle 2242 eines Antriebs 2243 verbunden. Der Antrieb 2243 ist ein 12 Volt Gleichspannungsmotor, der seinen Strom über hier nicht gezeigte Leitungen von der Steuer- und Regelvorrichtung 2265 bezieht. Der Antrieb 2243 ist an einem schwenkbar gelagerten Anstellelement 2251 der Anstellvorrichtung 2250 mittels dreier Schrauben befestigt, von denen nur eine Schraube 2205 gezeigt ist. Das Anstellelement 2251 wird von einer Antriebsscheibe 2252 der Anstellvorrichtung 2250 geschwenkt, indem ein exzentrisch gelagerter Zapfen 2253 der Antriebsscheibe 2252 in ein Langloch 2254 des Anstellelements 2251 eingreift, wobei die Antriebsscheibe 2252 von einer Servoeinrichtung 2255, bestehend aus einem in einem Kunststoffgehäuse 2256 gelagerten Elektromotor (Kleingetriebemotor), angetrieben wird.Also fastened to the
Der Elektromotor ist ein 6-Volt-Gleichspannungsmotor, der seinen Strom wie der Antrieb 2243 über hier nicht gezeigte Leitungen von der Steuer- und Regelvorrichtung 2265 bezieht. Das Anstellelement 2251 ist im übrigen so geformt, dass bei Erreichen eines einen Schwellenwert überschreitenden Abstandes in der Freigabestellung F ein Schalter 2206 betätigt wird, der über hier ebenfalls' nicht gezeigte Leitungen mit der Steuer- und Regelvorrichtung 2265 elektrisch verbunden ist, wobei durch den Schaltvorgang der Stromfluss zur Servoeinrichtung 2255 unterbrochen wird.The electric motor is a 6 volt DC motor that draws its current, such as the drive 2243, from the
Die Eingriffstellung E wird nur nach einer an der Steuer- und Regelvorrichtung 2265 einstellbaren Zeitspanne eingenommen, und zwar immer dann, wenn ein Schließvorgang nicht oder nicht ordnungsgemäß, insbesondere manuell, beendet wurde oder wenn ein Schließvorgang durch manuelle Einwirkung unterbrochen wurde.
