    Inverse picking method for order picking in logistics warehouses. Inverse picking method for order picking in logistics warehouses. It is indicated by means of a "put-to-light" system to the operator the number of order units (22) to be placed in the order box (23). The system calculates the control weight (pc) of all the order units to be placed, and a balance (24) weighs the product box, obtaining an initial weight (pi). The operator places the indicated order units in the order box and in the balance (24) the product box is weighed, without the units that have already been ordered, obtaining a final weight (pf). Then calculate the actual weight (pr) of the order units actually placed, as the difference between the final weight (pf) and initial weight (pi). By evaluating the difference between the control weight (pc) and the actual weight (pr), it is possible to know whether the correct number of order units (22) has been placed in the order box.

    DESCRIPTIONReverse picking method for order preparation in logistics warehouses.

    Object of the Invention 5

    The present invention relates to a reverse picking method for order preparation in logistics warehouses, of the type that comprise preparing partial orders, consisting of placing an operator in a predetermined number of order units of equal known weight in a cash register. order from a product box that arrives through a 10 feed line, and which finds particular application in logistics solutions mainly for the pharmaceutical, veterinary and cosmetic sectors.

    Field of Application of the Invention
     fifteen
    The field of application of the present invention is part of the industrial logistics sector, especially the field of the process in warehouses known as preparation, triad or "reverse picking" of orders.

    Background of the invention

    In the field of logistics, the preparation or triad of orders or orders, commonly known as "picking" in the art, is one of the important operations in handling and movement of materials in a warehouse. Picking is a process consisting of collecting items from the order by extracting units or sets of units from a packaging unit, contained in pallets, containers, baskets, baskets, dispensers, hoppers, picking cars, etc., and depositing the order units extracted in other cargo units, located downstream in the logistics chain, for example in order boxes.
     30
    In the case of direct picking, the product boxes are in a stationary position near where the operator is located, which is filling the order box that moves on, for example, a conveyor or roller belt. In the case of reverse picking, the product boxes arrive by the conveyor or roller belt and are "chopped" by the operator who places them in resting order boxes. In the case of pharmaceutical products, the packaging units 35 can be medicine boxes, and the order boxes can be cardboard boxes containing the orders so that the physical distribution system is able to deliver it to the user or to the point of sale, in this case pharmacies.

    Picking is a basic process in the preparation of orders in the warehouses that greatly affects the productivity of all logistics chain, since, in many cases, it is the bottleneck of it. It is also the step of the order preparation process where there is more probability of accumulating errors. This makes order picking one of the most controlled logistics processes.
     Four. Five
    There are currently different means and procedures to improve the productivity of picking processes without being subject to space limitations, also known as “paperless picking”, one of the most used being known as “Picking By Light” ). In this case, “Put-to-Light” devices, devices based on LED indications or displays designed to guide workers in the tasks of grouping or consolidating the different products of an order are used. In this method, the “Put” -to-Light ”system guides the operator to the locations of the packaging units, and marks him by means of a luminous code which is the merchandise to be thrown, and by means of a number of a numerical display , the number of order units (boxes in the case of
    pharmaceutical products), to be taken from the location and deposited in the box containing the order. "Reverse picking", as already said, is the order preparation process based on "Put-to-Light" systems, ideal for complementing storage practices that follow the concept called "product to man", in which the merchandise to be extracted is presented in front of the operator and the reverse picking system allows it to be placed in the order in preparation. This method optimizes the operation of the automatic warehouse since it allows the simultaneous preparation of different orders by reducing the number of cycles required for the same number of lines to be prepared.

    An alternative method is the “Pick-To-Voice” (“Voice Triad”), in which the system guides the operator through simple voice instructions, which optimize, among other things, the efficiency of the operator while acting With hands free.

    Both systems improve the efficiency of operators and reduce errors. However, the problem of errors consisting of differences between the quantities requested and the quantities actually served in the customers' orders, due to human errors in the “Pick-to-Light” reverse picking system, remains. This entails the inconvenience of having to physically review all the boxes of each sales order so that there is no difference.
     twenty
    The present invention aims to provide a solution to the problem and inconvenience cited.

    Explanation of the invention.
     25
    For this purpose, the object of the present invention is a novel method of picking orders in warehouses in logistics, of the type mentioned at the beginning, which in essence is characterized by a balance adjacent to the area in which an operator is located , communicated with a computer system, the method comprising the steps of:
     30
    A. indicate to the operator the number of order units of each partial order to be placed in each order box;

    B. calculate the system the control weight (Pc), consisting of the total weight of all the order units to be placed in the order box; 35

    C. weigh the product box on the balance, before the operator places one in the order box the first product unit of an initial partial order, obtaining an initial weight (Pi) of the product box;
     40
    D. place the operator in the order box the order units indicated in step A), starting from the product box;

    E. Weigh the product box on the balance once the operator has removed from it the last partial order order unit, obtaining a final weight (Pf) of the product box; Y

    F. calculate the system the real weight (Pr), consisting of the total weight of the actual order units, such as the difference in weights (Pi - Pf) between the initial (Pi) and final (Pf) weights, being Pr = Pf - Pi. fifty

    According to another characteristic of the method of the present invention, if the actual heavy weight Pr is equal to the control weight Pc, then a signal is given to the computer system indicating that the partial orders have been well placed, informing the operator of this.

    Otherwise, and if the actual heavy weight Pr is greater than the control weight Pc, then a signal is given to the computer system indicating that more order units have been placed, informing the operator to perform a inspection and correction of the order and return the method to step E). 5

    Alternatively, if the actual heavy weight Pr is less than the control weight Pc, then a signal is given to the computer system indicating that less order units have been placed, informing the operator to perform an inspection and correction. of the order return the method to step E). 10

    Preferably, step A) of indicating the operator is carried out by means of a display of a "put-to-light" device.

    Brief description of the drawings 15

    The detailed description of a preferred, but not exclusive, embodiment of the method of picking orders in logistics warehouses, object of the invention, for which better understanding some drawings are given, given by way of illustrative example and not, is given below. limitative. In these drawings: 20
    Fig. 1 is a schematic perspective view of a reverse picking workstation, in which the method according to the present invention is practiced;

    Fig. 2 is a flow chart illustrating a preferred embodiment of the picking method according to the present invention; and 25

    Fig. 3 is another flow chart illustrating a variant of the picking method illustrated in Fig. 2.

    Detailed description of the drawings 30

    In said drawings, the operating mode of the reverse picking method of orders in warehouses can be seen, in accordance with the principles of the present invention, in which order units 22 of one or several partial orders of a purchase order, contained in a product box 21 that arrives on a conveyor 20, are placed by operators 35 in respective and corresponding order boxes 23, in an operation that in the slang is also known as "chopping". This is shown in Fig. 1, in which an area of a warehouse in which the reverse picking according to the invention is carried out has been drawn. The present invention is applicable in particular, but not exclusively, to pharmaceutical, veterinary and cosmetic products logistics. In this case, each order unit 22 may correspond to 40 a medicine box, an out-of-box bottle, independent blisters, etc.

    The picking method of the invention is applicable to a reverse picking system ("put-to-light") in warehouses of industrial logistics, and is based on a computer system, connected to a balance 24, which is located close to the operator's work area, and a 15 '45 database that, among other things, has information about the weights of the order units. In the “put-to-light” system, it informs the operator, by visual means on displays 25, for example of LEDs, the location of the order box 23 for the order units 22 and the number of each of them.
     fifty
    In the flowchart of Fig. 2, a variant of the method for an order or order for a "chop" corresponding to a single product is illustrated.

    In it you can see that in step 1 the picking process starts, and in step 2 it is shown
    by a display 25 of the operator's put-to-light system, one corresponding to each order box 23, the location of each of the types of order units 22 to be chopped and the number of each of them. A light display and LED digits can usually be used for this purpose.
     5
    In step 3, the computer system calculates the control weight (Pc) consisting of the total weight of all the order units 22 to be placed in the order box 23 by assigning, by calculation from the data on the weights of the units recovered from the 15 'database.
     10
    In step 4, the balance 24 weighs the product box 21, before the operator has introduced the first order unit 22 in an order box 23, assigning it the value Pi, or initial weight.

    Next, in step 5, the user places the first order unit 22 in an order box 23, being interrogated by the system in the check step 6, if the current one is the last order unit 22 that is entered. If the answer is NO, it is returned to 5 for the operator to enter a new order unit 22. If the answer is YES, the operator will indicate it by pressing a button or key or similar action, and the method goes to step 7 , where the balance 24 weighs the product box 21 once the operator has removed from it the last 20 order unit 22 of the partial order obtaining a final weight Pf of the product box 21.

    Then, in step 8, the actual weight Pr of the product box 21 is calculated once the order units 22 have already been discounted, such as the weight difference:
     25
    Pr = Pi - Pf

    In step 9, it is questioned whether the actual weight Pr, is equal to the control weight Pc, by means of the question

    Pr = Pc , 30

    or other equivalent interrogation.

    If the answer in 9 is YES, it is significant that the actual weight entered is correct, and therefore the number of order units 22 "chopped" is also correct, so that the method goes to step 10, in which the system indicates to the operator that the “chop” has been carried out correctly, for example by means of a green light, to end the current picking operation and eventually move on to the next one.

    If, on the contrary, the answer at 9 is NO, it is significant that the actual weight entered 40 is incorrect, and therefore the number of order units 22 "chopped" is also incorrect, so the method goes to step 12, in which the system indicates to the operator that the “chop” has been done incorrectly, for example by means of a red light, to then go to step 13, where it is questioned whether the actual weight Pr is less than the control weight Pc. Four. Five

    If the answer in 13 is YES, this means that fewer order units 22 have been placed than those specified in the order, so the method urges the operator to place one more order unit 22 in the order box 23 (step fifteen). If the answer in 13 is NO, that is, if the actual weight Pr is less than the control weight Pc, this means that in some order box 23 there are 50 order units 22 in excess, and the method urges the operator to remove a order unit of the order box 23 in question (step 14).

    Following both steps 14 and 15, the method returns to step 7, in which the balance 24
    weigh the product box 21 again, to continue repeatedly as explained therein to steps 8 and following.

    In the flowchart of Fig. 3, the variant of the method in which the operator makes several “chopped” orders of different products before the check in step 6 is illustrated, in order to optimize time. This is the case in which the system gives the order to enter a product far from the weighing zone in the empty order box. In this case it is convenient to move the product box to a position close to that of the order units of the product to be placed. Since the order box is far from the weighing area, the system indicates it to the chopper operator, who can nevertheless press the button in step 6 to receive the next 10 order, thus being able to perform several operations in the steps 4 and 6, before returning to the weighing zone to check if the bites have been done correctly, that is to say, to execute step 7 and following.

    In this case, if in step 9 the answer is NO, when the operator does not know which of the orders 15 has been performed incorrectly, for not having been individually checked, in step 12, on display 25 it will be possible to visualize which have been the orders made without checking, so that the operator can manually verify and rectify the chopping (step 17), after which the method returns to step 7, step 7, in which the balance weighs the order box again, to continue repetitively as explained from there to steps 8 and following. twenty

    Those skilled in the art will appreciate that the picking method of the present invention allows the problem and inconvenience explained at the beginning to be solved simultaneously, as it allows staff to avoid reviewing all the boxes of a purchase order once prepared, as it is their own system which performs the verification in an automatic way "on-line". The method allows the operator to work with greater confidence because it is the system itself that alerts you in case of error, which increases your performance and self-esteem, in addition to adapting to the quality principle of resolving errors wherever they start and not in subsequent processes.

    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is stated that everything that does not alter, change or modify its fundamental principle is subject to variations in detail.
