Abstract

A refrigerated container and an associated method for closing or opening a removal cross-section of a refrigerated container by at least one laterally guided and displaceable cover element are known. The closing and/or opening procedure is initiated automatically using a closing and/or opening device after a specific time span and either automatically ended by reaching the closed position or the open position or automatically interrupted by a force component of an interfering force which counteracts the particular lateral movement and exceeds a threshold value. It is disclosed here that a frictional connection and/or form fit between the cover element and/or the refrigerated container and/or the closing and/or opening device is advantageously neutralized outside the time of the automatic closing and/or opening procedure, to thus allow manual displacement of the cover element without having to apply an additional manual force corresponding to the threshold value.

Description

Cooling container with closing and / or opening device and related method

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 of an open position, in particular a product removal position, in between a closure side of the cooling container or another cover member and ei¬ ner closure side of the cover member a gap is present, in a Schließstel¬ ment can be transferred, in which there is substantially no intermediate space between the closure side of the cooling container or the weite¬ ren cover member and the closure side of the cover member, wherein a closing and / or opening device automatic closing and / or opening process can be initiated and after a determinable Zeitspan¬ ne either by reaching the closed position or the open position automatically be¬ terminated or by a lateral movement counteracting and a Schwellenwe rt exceeding force component of an interfering force is automatically interrupted and a method for this purpose.

Cooling containers of the aforementioned type are known, for example, from DE 101 18 437 A1, in which the cover members of a freezer are coupled with a cable or belt system to a closing and / or opening device in the form of a drive. Also called in DE 101 18 437 A1 are further closing and / or opening device, such as direct drives via gears or rods, friction wheels or hydraulic or Pneumatikzy¬ cylinder. A manual displacement of the lid is not provided in DE 101 18 437 A1.

DE 43 35 458 A1 further discloses a sliding lid closure in refrigeration and freezing zones, which opens or closes the sliding lid 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 thus still possible, in particular in exceptional cases, for example in the event of a power failure.

DE 203 08 256 U1 discloses a furniture drive for moving a furniture element where a jamming protection and / or manual actuability is formed or ensured by a slip clutch. Finally, US Pat. No. 3 599 371 discloses a semi-cylindrical goods display furniture which can be opened and closed automatically by actuation of a push-button.

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, whereby an exchange of air necessary for the formation of ice and the resulting disadvantages can only take place in severely shortened periods of time , 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 taken or supplied a product from the interior of the cooling container, has not or not completely transferred the cover member into a closed position after removal or delivery within the specified period of time.

Although the automatic closing and / or opening operation of the said closing and opening devices is intended to contribute to lower energy consumption, above all in order to rule out manual incorrect operation, such as accidentally leaving the removal cross section open, it is obvious that initially more electrical energy is required - Nergie is consumed for the automatic closing and / or opening process itself.

The object of the invention is to propose a method which makes it possible to further reduce the energy consumption, to extend the life of the closing and / or opening device and to make it possible to provide manually operable freezer cabinets with an automatic closing and / or opening device ,

The object is, starting from the method of the type described input, achieved in that a frictional connection and / or a positive connection between the lid member and / or the cooling container and / or the closing and / or opening device outside the period of the automatic closing and / or opening operation is canceled.

By eliminating the frictional connection and / or the positive connection, the cover element can be displaced manually outside the closing process by a lateral movement increasing or decreasing the gap. Due to the simple manual closing and / or opening operation as a rule compared to the exclusively motor Verschie¬ tion of the cover member, as provided for in DE 101 18 437 A1, DE 43 35 458 A1 and US 3 599 371, considerable power and thus cost savings are possible. Nevertheless, manual misconduct, if advantageous, compensated to prevent a permanent open standing of the cooling tank. Because 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 executed, the operating time of the closing and / or closing operation is Opening device significantly shortened, so that extends the life and the maintenance is reduced. In addition, it is perceived by the customer as pleasant, the closing and / or opening process

The invention thus makes it possible to wait in parallel for the automatic (ie, a drive) and the manual movement of the cover member, the manual movement being effected by decoupling during the decoupling Anyway, the overcoming of additional, caused by the closing and / or opening device frictional forces caused by a slip clutch or resistors is not necessary, so there is a high ease of use.

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 Kraft¬ conclusion, takes place between about the closing and / or opening device and the Deckelor- gan 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 can also be fastened to the cover member and the direct force fit between the closing and / or opening device and the cooling container can 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. Positive connections are formed by the intermeshing of at least two connection partners. As a result of the mechanical connection, the connecting partners can not detach from one another without or in the event of an interrupted power transmission through the closing and / or opening device. The direct positive connection be¬ in this case between the gear as the first connection partner and the Zahnstan¬ ge as the second connection partner. However, an indirect positive connection exists, for example, between the cover member and the cooling container if, in the presence of immediate positive locking, the electric motor which drives the toothed wheel is connected to the cover member and the toothed rack is attached to the cooling container.

The repeal of the frictional connection and / or the positive connection means that the positive and non-positive connection between the connection partners is achieved. A positive connection between the cover member and / or the cooling container and / or 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 becomes clear that only the switching off of the electrical energy for the operation of the closing and / or opening device does not necessarily mean that the frictional connection and / or the positive connection are canceled, since the connection between the connection partners does not have to be released in this case , Only with release of said connection partners vonein¬ other is a corresponding repeal. When the positive and / or positive connection is lifted, it is thus no longer necessary to manually overcome internal frictional forces or moments of the closing and / or opening device.

As long as the closed position of the cover 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 Deckelor¬. 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.

Advantageously, the period begins to run after a movement of the cover member, in particular when the opening movement of the cover member is terminated or interrupted, since the time for the removal or supply of products in the cooling container then un¬ dependent on the time required for the opening process is. 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.

An advantageous development of the invention can be achieved in that the Schwel¬ lenwert is measured substantially permanently during the automatic closing operation to create the most timely interruption when an interfering force occurs.

A further advantage can be achieved in that the specific period of time is dependent on whether the closing operation performed last was ended 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, whereby a multiplicity of further functions for control and monitoring can be fulfilled in the latter.

According to one development of the invention, the force component can be determined by measuring a current absorbed by a drive device, whereby a particularly easy-to-implement yet sufficiently sensitive possibility is created to detect the disturbance force. Finally, the method can be further developed in that the threshold value of the force component of the disturbing force that triggers the interruption, in particular in a first-time commissioning of the closing and / or opening device, by means of at least one metrological detection of a voltage and / or current during the trouble-free automatic closing and / or opening operation and upon reaching the closed position or open position and programmatically determined. As a result of the automatic determination of the threshold value, differently closing and / or opening devices with a definable disturbing force can also be switched off. A calibration of the closing and / or opening device by qualified personnel can thus be dispensed with, so that the installation can in principle also be carried out by auxiliary personnel.

The object of the invention is also to propose a cooling container, which makes it possible to use the method described.

The object is achieved by a cooling container in which it is provided that a force closure and / or a positive connection between the cover member and / or the cooling container and / or the closing and / or opening device outside the period of the automatic closing and / or opening operation can be canceled. The advantages of the cooling container correspond to those of the method.

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.

A development further provides that a driving element on the lid member be¬ festigbar and laterally of the locking device, in particular linear-lateral, relative to Kühl¬ container is movable, which additionally also the respective cover organs, in particular their handle elements, adaptable and / or by a hinge can be folded up.

The invention can also be further 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. Due to the coupling and decoupling of the drive device with the guide It can be achieved that a manual opening and closing of the cooling container outside of the closing process, that is to say during decoupling, can take place without any particular force.

Another development is that the drive device is fixedly attached to the cooling container and the guide device to the lid member, however, it is alternatively be¬ preferred that the guide device is fixedly secured to the cooling container and the drive means on the lid member.

It has furthermore been found that the drive element can be transferred between the release position and the engagement position by means of a positioning element of a positioning device, since the coupling and decoupling can be automated particularly easily by means of a positioning element.

It is particularly advantageous for certain applications when a switch in the release position can be actuated by the drive device and / or the setting element. Due to the switch position, the instantaneous position of the drive device is always kept in an extremely simple manner and can be easily interrogated, for example 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 for switching the supply current, for example for the drive device or for a positioning drive of the positioning element, for example by the drive device driving the drive element only when the switch is no longer in the switch position corresponding to the release position ,

It is particularly advantageous if the positioning element is movable by means of a positioning drive of the drive device, wherein it is preferred if the positioning drive is a servo device with a drive disk with an eccentrically arranged pin which engages in a slot in the positioning element Servo device represents a low ein¬ purchasable mass product that has been used for many years in model making.

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 entrainment element. By using a moving On the one hand, only the length of the guide element, which can be designed as a toothed rack, for example, and the entrainment element on the other, must be adapted to the respective cooling container. By means of this adaptation, which can be carried out easily and inexpensively, the same closing device can be used for most cooling tanks. A retrofit already existing cooling tank is very easy.

A development of the invention also provides that a limit switch is attached to the cooling tank or the closing device, which is actuated in the closed position by the Wagenvorrich¬ device and / or the lid member and in a particularly simple manner, the 0 closed position for a shutdown of the power supply can use to the drive device.

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, the supply line being guided by means of an energy guiding device, in particular an energy chain consisting of a plurality of chain links. Energy chains are a mass and are therefore cheap to buy. They generally allow a systematic, ein¬ times, safe, yet movable routing of cables.

A further development of the invention is additionally achieved in that the cooling container has two cover elements which can be pushed one above the other, each being provided with a carriage device, whereby they can be moved independently of one another and connected to one end of a common and thus efficiently used energy guiding device In addition, a common guide rail and a common guide element are provided for both carriage devices, wherein the guide rail and the guide element are connected to one another in a connectable or one-piece manner.

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 to be seen in particular 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 Aufbaukörpem, and thus by the use of fertil Cover not only the other elements of the locking device against πigung be protected, but basically no additional space is needed because you can get rid of upgrading conventional supermarket refrigerated containers with the erfindungs¬ proper locking device of said body structure meaningful.

Of course, the advantageous closing and / or opening device can be advantageously used not only for cooling containers, but also for uncooled Warenpräsentati¬ onsmöbel 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. On the other hand, instead of or in addition to the preferred electrical and electromechanical components, it is also possible, for example, to use hydraulic components for the closing and / or opening device, without departing from the scope of the invention. Thus, it would be conceivable in principle to equip a hydraulic cylinder with a controllable magnetic valve which can switch the hydraulic cylinder without pressure and thus eliminate a frictional connection.

Reference to an embodiment of an inventive cooling container will be explained in more detail.

In the closed position S, the closure sides 1220, 1220 'of the cover members 1200, 1200' are pulled over the closure sides (not visible here), in particular the left and right inside of the cooling container 1000, in such a way that no permeable intermediate space Z is more is available. The first cover member 1200 is mounted higher by means of its guide rails than the second cover member 1200 ', so that it can be performed over the latter. Both lid members 1200, 1200 'have sealing elements, not shown here, on their closure sides 1220, 1220', which ensure a better partitioning of the cooled interior space 1 100, which is shown in FIG. 2, against the warmer ambient air.

Also shown is a closure device 2000 having two carriage devices 2200, 2200 'with covers 2299, 2299'. The carriage devices 2200, 2200 "are movably guided along a guide device 2300. The power supply of the two carriage devices 2200, 2200 'takes place via supply lines, not shown here, which are mounted in a power guiding device 2220 in the form of a so-called energy chain with a plurality of chain links 2222 The entire closure device 2000 is covered by a cover 2400. The cover 2400 has a switch 2500 on an information and advertising surface 2420, which is chamfered at an angle of approximately 100 degrees to the base surfaces of the lid members 1200, 1200 ' in the form of a rotary switch with which the entire power supply for the closing device 2000 can be interrupted The energy guiding device 2220, the guide device 2300 and the cover 2400 are shown separated from the remaining elements of the closing device 2000 for a better overview 200 Incidentally, 0 does not increase the occupied base area of the cooling tank 1000, so that two cooling tanks 1000 with closing device 2000 can also be flush with their rear sides not visible here, for example for improved or unchanged good utilization of space in the middle aisles in supermarkets ,

1, but partially in an open position O, namely that of the first (left) lid member 1200. Between the closure side 1220 of the lid member 1200 and the (left) closure side 1050 of the cooling container 1000 is located Thus, a gap Z, which allows a convenient removal or storage of products not shown here in the cooling tank 1000. Here is the first Wagen¬ device 2200, which is coupled by means of a first driving element 2210 with the lid member 1200, but not in a maximum achievable open position, but with a distance of half the length of the carriage device 2200 in front. Incidentally, the carriage device 2200 in no way hampers the complete opening or closing of the lid member 1200. The second carriage device 2200 ', which is coupled to the second (right) lid member 1200' by means of the second driver element 2210 ', is located furthermore in the closed position S, as already shown in FIG. 1. The energy guide 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. Also in Fig. 2, the power guiding device 2220, the guide device 2300 and the cover 2400 of the remaining elements of the closing device 2000 for the sake of clarity shown separately.

FIG. 3 shows in detail and enlarges the carriage device 2200, the guide device 2300 (shown in abbreviated form) and the energy supply device 2220 (also shown shortened) with its individual chain links 2222.

The carriage device 2200 runs by means of four sliding or ball-bearing plastic guide wheels 2201-2204 in an upper and lower profile groove 2321, 2322 of an aluminum guide rail 2320 of the guide device 2300, wherein each guide wheel 2201-2204 has a projecting collar 2201-2204 ' with which it engages in each case in the profile grooves 2321, 2322. The guide wheels 2201-2204 are fastened to a support plate 2230 by means of screws 220V-2204 "and steel tubular spacers 221 1-2214 shown in FIGS. 6 and 7.

Also fastened to retaining plate 2230 is entrainment element 2210, a drive device 2240, an adjustment device 2250 and a control and regulating device 2265 incorporated in a plastic housing 2260 in the form of 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 locking, which otherwise exists between the gear as the first connection partner and the rack as the second connection partner, is in the release position F aufgeho¬ ben. The drive element 2241 is connected to a motor shaft 2242 of a drive 2243. The drive 2243 is a 12 volt DC motor which draws its power from the control device 2265 via lines not shown here. The drive 2243 is attached to a pivotally mounted adjusting element 2251 of the adjusting device 2250 by means of three screws, of which only one screw 2205 is shown. The adjusting element 2251 is pivoted by a drive pulley 2252 of the setting device 2250, in that an eccentrically mounted pin 2253 of the drive pulley 2252 engages in a slot 2254 of the setting element 2251, wherein the drive pulley 2252 consists of a servo device 2255 consisting of a plastic housing 2256 mounted electric motor (small geared motor) is driven.

The electric motor is a 6 volt DC motor that draws its current, such as the drive 2243, from the control device 2265 via lines not shown here. Incidentally, the adjusting element 2251 is shaped in such a way that upon reaching a distance exceeding a threshold value in the release position F, a switch 2206 is actuated which is electrically connected to the control and regulating device 2265 via lines which are likewise not shown here Switching the current flow to Servoein¬ direction 2255 is interrupted.

Fig. 4 shows once again particularly illustrates the release position F of the Anstellelements 2251 that is pivotally mounted on one side of a bearing fork 2257. The distance between the drive element 2241 and the guide element 2340 shown in FIG. 4 is the maximum achievable, since the pin 2253, which engages in the slot 2254 of the Anstellelements 2251, with respect to the guide member 2340 in the largest possible outer position. In the release position F, the carriage device 2200 can be displaced with the cover element 1200 without any particular effort, since the carriage device 2200 and the cover element 1200 are coupled to one another by the carrier element 2210, but the drive element 2241 and the guide element 2340 are disengaged.

5 shows an engagement position E of the positioning element 2251 with the guide element 2340. The distance between the drive element 2241 and the guide element 2340 is the minimum achievable, since the pin 2253 in this position in a direction opposite the guide is located 2340 the smallest possible spaced inner position. The carriage device 2200 can no longer be moved manually with the cover member 1200 in the engaged position with self-locking of the drive, or only with much increased effort, namely, when the drive is not self-locking. There is a positive connection between the gear and the rack.

The engagement position E is assumed only after a period of time which can be set on the control and regulating device 2265, namely whenever a closing operation has not been completed or not properly, in particular manually, or when a closing operation has been interrupted by manual action. The closing operation is terminated by actuating a limit switch 2280 shown in FIG. 7 by a switching angle 2350 mounted between an angle member 2360 and the guide rail 2320. Unter¬ remains an operation by manual cover shift, takes place after a period of time, which ^{■ is} preferably preselected at about 7 seconds, the closing process automatically by first the servo 2255 moves the Anstellelement 2251 of the release position F in the engaged position E and simultaneously or for a short time later the drive 2243 is supplied with power, wherein the drive element 2241 the carriage device 2200 with the Deckel¬ organ 1200 relative to the guide member 2340 in the direction of the closed position S drives.

If, during the automatic closing process, one of the associated lateral movement of the lid member 1200 is applied with a force exceeding a threshold force component of an interfering force, either generated by abutment or touching the lid member 1200, the recorded drive current of the An¬ drive 2243 increased by some up to a few hundred milliamps or microamps. If this current increase 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. Optionally, an interrupt signal may be output by suitable signaling means. After a second period of time, for example after 10 seconds, which, moreover, can be selected independently of the first, the automatic locking 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. 6 and 7 illustrate the position of the guide wheels 2201-2204 on the retaining plate 2230. In addition, a U-profile of the driving element is shown. By means of a first angle element 2360 and a first opposing second angle element, not shown here, the entire closing device 2000 is fastened to the cooling container 1000 by means of screws, which are likewise not shown here.
