Definitions

  • the invention relates to a method for controlling the release of telescoping trolleys, such as shopping trolleys and the like, which are coupled to one another in a row. according to the preamble of claim 1 and devices for performing the method.
  • DE-A 2 900 367 and DE-A 2 554 916 and others. are devices to ensure the proper return of borrowed trolleys, such as shopping carts, etc. known, which is preferably used in shopping centers, supermarkets, self-service markets, etc. to be used.
  • the known devices work according to the following principle. In order for a shopping cart to be removed from a stationary row of cars coupled to one another, a coin or token must be inserted into the last coupled shopping cart so that it is released to a certain extent either automatically or by pulling out a coupling member from the penultimate parked car. A customer will only get the inserted coin or token back if he brings the car back to one of the designated places, preferably at the exit or in the parking lot, and connects it there properly.
  • the user has to couple the trolley that he no longer needs directly to the designated location or to a shopping cart that has already been parked there.
  • the coupling member provided at the delivery point or on the previously parked car is to be inserted into a corresponding receptacle, whereupon the inserted coin or token is ejected or released so that it can be removed by the customer.
  • the aim of the invention is therefore to control the release of transport trolleys pushed into one another and coupled to one another in a row, such as shopping carts, in such a way that transport trolleys which are properly coupled from a series of trolleys, transport trolleys can either be pulled off to the front and / or back or can be uncoupled.
  • the invention is intended to create reliably working devices for carrying out the method.
  • this aim is achieved in a method for controlling the release of nested and coupled to a series of transport trolleys, such as shopping carts by the method steps specified in the characterizing part of claim 1. Furthermore, this goal is achieved in devices for performing the method by the features in the characterizing part of claim 2 or 6. Advantageous further developments of the devices according to the invention are the subject of the further subclaims.
  • the position is taken first this trolley in a row formed of coupled trolleys based on the position of the adjacent trolley. That is, it is determined whether the dolly is at the beginning, at the end, or at an intermediate position. Depending on the determined position of the transport carriage into which a coin has been inserted, a decision is then made as to whether the respective transport carriage is released to the front, ie in the direction of the front, for receiving goods, or to the rear, ie in the opposite direction or can be removed or not. This in turn means that the desired removable transport trolley must be properly coupled and must be at the beginning or end of such a series of trolleys.
  • an opto-electronic coupling arrangement blocks the coupling of another trolley, for example. This ensures that no other transport vehicle can be coupled to a released and usable transport vehicle, for example within the supermarket or in its parking lot.
  • a device for carrying out the method in which an orientation device is provided on each transport carriage for determining its position in a row of vehicles, by means of which it is determined whether in front of and / or behind this carriage, i.e. in the direction of the loadable front area, which is preferably designed in the form of a basket in shopping carts, and / or in the direction of the rear area, i.e. in the direction of the push handle attached to the shopping cart and oriented upwards, another transport cart is coupled or not.
  • the orientation system is used to determine whether the triggered car is either the first or the last car in a parked row of cars.
  • the corresponding coupling mechanism is opened after the respective position of the carriage has been determined by a control circuit acted upon by the orientation device, so that the carriage moves forwards or backwards can be deducted. Simultaneously with the removal of the respective carriage, an associated coupling arrangement is switched off, controlled by the electronic circuit arrangement acted upon by the orientation device, which then ensures that no other carriage can be coupled to the carriage just triggered.
  • the coupling arrangement assigned to the orientation device of a carriage is kept in a non-coupling-ready state, as long as the carriage is used and is not properly parked again at one of the locations provided for this purpose or in an already parked location at these locations Car is inserted and coupled there. Only when this state is present again, the coupling arrangement of the car that has just been properly parked is switched to "ready for coupling" by the orientation device, so that a further car can be coupled to the car that is currently in use.
  • yet another device for carrying out the method in which of two separate, activatable coupling elements of a coupling device attached to a transport carriage, one of which is oriented toward the front and one towards the rear region of the transport carriage, when one is actuated Trigger mechanism, which is assigned to the coupling device attached to the transport carriage and is preferably in operative connection with it, depending on the position of this transport carriage in the row of carriages only that of the free, ie coupling element opposite coupling element can be activated.
  • a coin, a pledge, a token, etc. is inserted into a receiving device of a correspondingly assigned or operatively connected coupling device which is attached to a transport trolley, for example a shopping trolley, which at the beginning or at the end of one is a number of cars formed row, this trolley can be easily disconnected.
  • a transport trolley TP is shown schematically in the form of a shopping trolley, in which only the push handle GR running perpendicular to the plane of the drawing is designated, which in the schematic representation is referred to as the rear area H of a transport trolley TP, during which in FIG Fig.1 right part of the trolley TP in the schematic representation is to be regarded as the front part V.
  • a schematized transport trolley TP2 is indicated in the middle area below the schematically represented transport trolley TP, behind or in front of which further transport trolleys TP1 and TP3 are respectively provided.
  • the three indicated transport cars TP1 to TP3 each coupled together.
  • each transport trolley has an actuatable clutch BK in its front area V and a rigid clutch SK in its rear area H.
  • each transport trolley TP which consists of sensors G1 and G2 as well as receivers in the form of sensors S1 and S2.
  • a sensor and a sensor are provided by the orientation device in the front and in the rear area of each transport carriage, namely the transmitter G1 and the sensor S1 in the rear area H and the sensor G2 and the sensor S2 in the front area V of each transport carriage TP.
  • a coupling arrangement is provided on each transport carriage, which has a further transmitter G3 and a receiver in the form of a further sensor S3.
  • the sensors G1 and G2 of the orientation device are active sensors, preferably in the form of permanent magnets, while the sensors S1 and S2 are receivers that can be actuated by such sensors, preferably in the form of reed switches.
  • the coupling device has an encoder G3 which can be activated by a control circuit (not shown in more detail), for example in the form of an infrared diode, and a receiver which responds to such an encoder, namely the sensor S3, for example in the form of a photodiode.
  • each transport trolley TP is only shown schematically as an approach which is approximately rectangular in cross section and which is encompassed by an actuatable coupling BK.
  • Each actuatable clutch BK is also schematically indicated as a recess of approximately rectangular cross section provided on each transport carriage and can be actuated, for example, by means of electromagnetic elements, to release, as will be described in more detail below, the rigid coupling of a transport trolley TP arranged in front of it.
  • the transmitters G1 to G3 assigned to each transport carriage and the corresponding sensors S1 to S3 are supplemented by a further number which corresponds to the number assigned to the respective transport carriage . That is, for example, the sensors G1 to G3 and sensors S1 to S3 provided on the middle transport carriage TP2 are provided with the additional number 2 corresponding to the transport carriage TP2, so that the sensors of this transport carriage as sensors G12 to G32 and its sensors as sensors S12 to S32 are designated.
  • the functioning of the orientation device formed from the transmitters G1, G2 and the sensors S1, S2 of each transport carriage TP and of the coupling arrangement formed from the activatable transmitter G3 and the corresponding receiver in the form of the sensor S3 is described using a function table shown in FIG.
  • this function table only the meaningful or permitted functions are listed in digital notation, so as not to impair the clarity of the table.
  • the functions of the three sensors S1 to S3 are in digital notation in the left three columns Effect of an inserted coin M and a so-called clutch control KK specified, while in the right three columns the two possible functions of the activatable transmitter G3, a coin slot or coin evaluator M1 and the actuatable clutch BK are listed.
  • Section A lists the possible situation for a free-standing car; Section B describes the situations in which no further carriage is coupled behind the transport carriage TP2 in the middle in FIG. the transport trolley TP1 shown in Figure 1 is neither coupled nor provided. Section C shows the case where there is no other transport carriage in front of the transport carriage TP2, i.e. the transport trolley TP3 shown in Fig. 1 is neither coupled nor available. Finally, section D describes the case shown in Fig. 1 that the transport carriage TP2 is in a central position, i.e. a transport trolley is coupled both in front of and behind it.
  • the transport carriage TP2 in the middle in FIG. 1, behind which the transport carriage TP1 and in front of which the transport carriage TP3 is arranged or can be coupled.
  • the sensor S12 provided in the rear region H of the transport carriage TP2 uses the sensor G21 provided in a corresponding position in the front region V of the transport carriage TP1 to determine whether a carriage, for example the transport carriage TP1, is still present behind the transport carriage TP2 or Not.
  • the sensor S22 provided in the front region V of the carriage TP2 with the aid of the sensor G13 provided in a corresponding position in the rear region H of the transport carriage TP3, it is recognized whether a carriage, for example the carriage TP3, is present in front of the carriage TP2 or not.
  • the respective transmitters G1 and G2 of the individual transport carriages TP are active elements, for example in the form of permanent magnets, while the elements S1 and S2 which are arranged at suitable points and respond to the active transmitters G1 and G3 are preferably in the form of reed switches are. With the aid of these transmitters G1 and G2 and the sensors S1 and S2 assigned to them on the other cars, it can thus be recognized whether at least one other transport car is coupled in front of and / or behind a transport car.
  • each transport carriage TP By means of the sensor S3 provided in the front area V of each transport carriage TP, it can be recognized whether another transport carriage would like to be uncoupled in front of the respective carriage.
  • the activatable sensor G3 arranged in the rear area H of each transport car TP is assigned at a corresponding point in the front area V of the other transport car the sensor S3 which can be acted upon by the sensor G3.
  • a photodiode and, for example, the transmitter G3, an infrared diode can be used, with the circuit not shown in detail influencing only the infrared diode, i. is acted upon and activated.
  • the transport trolley TP2 should stand alone somewhere. That means its two sensors S12 and S22 are 0, because behind and in front of the Trolley no other transport trolley is present. Then the sensor S32 is also 0, since, as already explained above, no other transport carriage is coupled in front of the transport carriage TP2.
  • the column headed M is 1, which means that a coin M has been inserted.
  • the encoder G32 is switched to 0 by the control circuit.
  • the coin evaluator M12 is at 0 because the coin is stored and not ejected.
  • the actuatable clutch BK2 provided in the front area V of the transport carriage TP2 is open, ie, however, is not ready for reception for a rigid coupling SK of another transport carriage, since coupling from the front is not permitted.
  • Line 1 of section B now describes the case where, for example, a transport carriage is present in front of the transport carriage TP2, ie the transport carriage TP3 in FIG. 1, while no further transport carriage is present or coupled behind the transport carriage TP2.
  • the sensor S22 of the transport carriage TP2 is then actuated by the transmitter G13 of the transport carriage TP3, i.e. switched to 1. This expresses the fact that a further transport carriage, namely the transport carriage TP3, is present and coupled in front of the transport carriage TP2. In contrast, the sensor S12 provided in the rear area H of the transport carriage TP2 is 0 because, as stated above, there is no carriage behind the transport carriage TP2 and is coupled.
  • the sensor S32 of the trolley TP2 is 0; this means that no coin M has been inserted or stored. Since the transport carriage TP2 is coupled to the transport carriage TP3 arranged in front of it, its actuatable coupling BK2 is also 0. Since the transport carriage TP2 has been properly parked, the coin M has been ejected, which is why 0 appears in the fourth column. At the same time, this means that no new coin or token has yet been inserted. The same applies to the remaining columns as stated above with regard to row 2 of section A.
  • the transmitter G33 of the trolley TP3 is at 1.
  • the signal is then passed on if in front of a trolley, for example TP3, another trolley is TP4 in this case. If this were not the case, the trolley TP3 would be the last trolley and no further trolley would be coupled in front of it, i.e. there would only be two transport wagons next to each other and would be present.
  • the sensor G33 of the transport carriage TP3 is at 1, the sensor S32 is also at 1. No coin M has been inserted, which is why the fourth column is 0.
  • the clutch control KK is 1; i.e. the actuatable clutch BK2 is also 1.
  • the encoder G32 is 1 because the transport carriage TP3 is in front of the transport carriage TP2.
  • the coin slot M12 is at 1, since there is no coin M (see column four).
  • a coin M is inserted and in section B of line 4 on the table.
  • the control circuit sets the sensor S32 artificially to 0, which is indicated in section B, line 4 by a dashed number 0 ⁇ .
  • This artificial process lasts about 5s. That is, the sensor S32 is set to 0 for 5s; This means that the trolley TP2 must be removed in these 5s, otherwise the actuatable clutch BK2 is closed again and the coin M that has just been inserted is immediately dispensed again.
  • the actuatable clutch BK is opened. This now results in the case in line 2 of section B, since a coin M is inserted and kept in the shaft, which is why, as already detailed above, fourth column 1 and seventh column 0. Since the actuatable clutch BK2 is open for 5s, not only the last column, but also the clutch control KK2 is 0. This means that the trolley TP2 can now be removed.
  • the line applies 2 in section C. Since the coin M is kept, the coin shaft M12 is 0. At the same time, the encoder G32 is switched to 0 by switching. The rear transport carriage TP1 then opens its actuatable coupling BK1, so that the transport carriage TP2 can be removed. The command to the transmitter G32 has indicated to the transport trolley TP1 coupled behind that the transport trolley TP2 in front of it, which in this case is the last and therefore the foremost transport trolley, is to be coupled. As soon as the corresponding command has been issued to the encoder G32, the transport carriage TP1 then opens its coupling BK1 and the transport carriage TP2 can be removed. However, in contrast to section B of the function table described above, this situation remains and will not be undone after 5s.
  • this state remains. This means that after encoder G32 has been switched to 0, this state is no longer changed. If, for example, the just removed transport carriage TP2 with its rigid coupling SK2 is reinserted into the actuatable coupling BK1, no coupling takes place, since the transmitter G32 is still formed at 0 and therefore the corresponding sensor S31 of the transport carriage TP1 is not activated. For this reason, the coin M located in the transport carriage TP2 is not ejected. This fact is then a clear indication for the user that the trolley should be coupled in an impermissible manner.
  • Line 1 of section D of the functional table describes the case in which a transport carriage coupled in front of the transport carriage TP2 is to be removed, ie the transport carriage TP3 is to be pulled off to the front. Since at least the transport carriage TP1 is coupled behind the transport carriage TP2, the sensor S12 is at 1 the sensor S22 to 1 because it is activated by the encoder G13 of the trolley TP3. Since no coin M has been inserted, the fourth column is 0 and the seventh column 1. The actuatable clutch BK2 is still closed, which is why the last column in line 1 of section D 0.
  • Line 2 of section D shows the case in which the two sensors S12 and S22 of the transport carriage TP2 are each 1; however, sensor S32 is 0. This is the case if there is a carriage in front of and behind the transport carriage TP2.
  • the transport trolley TP3 has already been solved because the sensor S32 of the transport trolley TP2 is at 0. This means that the trolley TP3 is present, but already triggered by the insertion of a coin M.
  • Line 4 of section D then only shows the case in which a coin M is inserted into such a carriage TP2 standing in the middle. This is the only difference between lines 3 and 4 of section D. However, when a coin M is inserted, it changes None, because this coin simply falls through and the case is again in line 3 of section D.
  • FIG. 3 shows a perspective illustration of a housing 50 indicated by a broken line, in which a rod-shaped coupling device, designated in its entirety by 10, is accommodated, the coupling elements 11 and 12 of which are provided at both ends and are rigidly connected to one another by a rod-shaped central part.
  • the two coupling elements 11 and 12 are different; the element 11 formed at one end has the shape of a L-shaped hook in plan view, while the other coupling element 12 rigidly connected to it via the rod-shaped central part is designed as a hook-shaped part which is U-shaped in plan view.
  • the mutually parallel legs of the U-shaped element in plan view are of different lengths, namely the shorter leg of the U-shaped coupling element 12 is slightly more than the thickness or width of the rod-shaped central part of a coupling device 10.

Since this removes the connection between the two coupling devices 10 1 and 10 2, the trolley to which the coupling device 10 1 is attached can be pulled off, that is to say can be removed obliquely to the top right in the illustration in FIG.
  • the coupling element 121 of the coupling device 101 of the pushed car comes with the upper end of its long leg on the horizontally arranged L-shaped coupling element 112 of the coupling device 102 in plant.
