Definitions

  • the present invention relates to a device for transporting flat products, in particular flat products such as letter envelopes.
  • Such devices are used, for example, by larger companies with a high volume of correspondence.
  • companies include, for example, large telecommunications companies with a large number of invoices to be sent, insurance companies, large companies that have a high volume of mail to be sent, which is to be automatically created, enveloped and sent.
  • the letters are automatically transferred into envelopes in a so-called inserter and then sealed.
  • the envelopes come with different content, that is, both letters with a lot and with little pages, brochures with a thick seam and the like, from the inserter.
  • the letters are usually already on a conveyor belt, after which they are manually recorded by standing on this conveyor belt people according to certain criteria and transferred to transport crates.
  • These transport boxes are then delivered to the respective letter carrier or delivery company, which then takes care of sending the corresponding letters.
  • the effort is kept as low as possible at the appropriate letter carrier, is carried out by the aforementioned persons already pre-sorting in the corresponding transport baskets.
  • These criteria may in particular be related to the address information, so that, for example, a pre-sorting according to postal code areas can already take place.
  • This sorting can be designed differently differentiated, so that even a very fine sorting, depending on the size of the letter set, can take place.
  • the persons who perform the sorting proceed in such a way that they read off the corresponding postcodes on the enveloped letters.
  • corresponding markers are inserted in the address field of the letters, depending on the postal code areas. These markers can either then help the corresponding sorting person to more quickly recognize different zip code areas or be configured to be electronically recognized by a scanner. This then ensures through a separate unit that, for example, the letters in the continuous stream be transported with a slight offset on the tape, where a transition from the one to the next postal code area occurs.
  • This offset can then be easily recognized by the sorting persons, so that they need to pick up the letters between one and the next offset, for example, without having to concentrate further on the respective address fields.
  • a scanner can of course also read the postal codes directly by means of character recognition.
  • Such transporting and sorting processes may also be necessary for other sheetlike products such as cartons, blanks, folding cartons, plates, separating plates, for example made of plastic, paper, cardboard or metal, if these are supplied in larger numbers from a preliminary station, but in different package sizes should be further processed.
  • the present invention therefore an object of the invention to develop a transport device to the effect that the sheet-like products are so tangible that they are transportable individually or in groups.
  • a new method as well as a corresponding device for carrying out this method should be provided.
  • the object is achieved on the one hand by an initially mentioned device for transporting flat products with at least one feeder and a first transport unit having at least two transport elements which are arranged parallel to the transport direction and can be applied to mutually opposite side edges of the sheet-like products that the sheet-like products are held by the transport elements, held separately carrying and can be transported standing in the transport direction.
  • This device designed in this way makes it possible to pick up the corresponding flat products, which usually come horizontally or lying, for example, from an inserting machine, after transferring them into a standing position, that is to say essentially vertically, and transport them in succession.
  • This vertical or standing alignment of the flat products already corresponds to the arrangement in which the products are also received in a corresponding transport container.
  • Holding on opposite side edges, that is, looking in the direction of transport, on the right and left edges of the sheet products, has the advantage that the sheet products are now held on the opposite sides so that they can not easily change their position relative to one another , As a result, among other things, a uniform distance from one to the next flat product can be guaranteed.
  • the contact pressure of the transport elements applied to the opposite side edges should be selected so that the flat products do not slip off, be it due to gravity or other factors such as insufficient bending stiffness of the products.
  • Relatively heavy products must have a correspondingly high flexural rigidity in order not to buckle and thereby slip away, since with heavy products the contact pressure must be correspondingly higher.
  • the investment in the opposite side edges can also be made selectively, so that, for example, a round sheet product such as a disc or a plate between the transport elements is durable.
  • the attack on opposite side edges and not on the upper or lower edge has the advantage that, for example, a downward discharge with the aid of gravity of the transport elements is not hindered.
  • the device has at least a second transport unit, which has at least one transport element, through which the products in the transport direction can be further transported and released from the device, wherein the at least one transport element arranged parallel to the transport direction and at least an edge of the sheet-like products can be applied, so that the sheet-like products are held by the at least one transport element, separately supporting and transportable standing.
  • This embodiment has the advantage that a continuous operation of this device is made possible in a simple manner by this subdivision of the device into a first and second transport unit.
  • the first transport unit can be responsible, for example, for sorting
  • the second transport unit which can be controlled separately therefrom, can be designed, for example, for transferring the flat products into a transport container.
  • This is particularly advantageous with respect to the last point, since a change in operation on the second transport unit, which is carried out for transferring the sheet-like products in a transport container, no effect on the transport and the flat products in the first transport unit has.
  • the two-dimensional products can then be transferred, after appropriate sorting, into the second transport unit, from where the previously described transition into the transport containers can take place.
  • first and a second transport unit in the sense of two separate units and will also be referred to below, this means both structurally separate and uniform total transport units.
  • This designation is merely intended to indicate that an entire transport section, which the device has, can be divided into two separately controllable transport units.
  • the respective transport elements of the first and second transport unit are separate elements, but also that these transport elements have an entire transport element which is divided into different individual sections in accordance with the statements made above.
  • the second transport unit on two transport elements, which are mutually perpendicular to the transport direction variable in their distance.
  • This embodiment is advantageous in that the two-dimensional products can initially be continuously taken over by the two transport elements of the first transport unit.
  • the variability of the distance of the transport elements of the second transport unit to each other has the advantage that the sheet-like products that are transported in this second transport unit and are held at opposite side edges as in the first transport unit. By simply moving apart the transport elements, the products can be brought out of the holding engagement with these.
  • the flat products are thus by a change in the distance, namely a moving apart of the two transport elements of the second transport unit is released perpendicular to the transport direction. As a result, the sheet products can then be transferred either by gravity or by a separate mechanism in the corresponding transport container.
  • This embodiment has the advantage that conveyor belts easily allow continuous transport operation. This makes it possible to transport the sheet-like products variably, that is, at any distance from one another, since there are no separate and predetermined receptacles for the respective sheet-like products, which specify the positions of the individual products along the transport element. At the same time, this design also allows each product to be individually durable. Thus, the products can be arranged independently of each other between the respective transport elements. It is therefore irrelevant for the arrangement of a respective sheet-like products as many flat products are arranged in the transport direction before this and how many follow.
  • conveyor belts By selecting a suitable coating of the conveyor belt, for example with a foam or pimples, friction-supporting holding or engagement with the flat products can take place with the lowest possible contact pressure.
  • Another advantage of conveyor belts is that the transfer from the first transport unit into the second transport unit can be carried out continuously accordingly. This is for example possible by mutually offset in height in the transport direction but overlapping conveyor belts. Also conceivable is an arrangement in which the first and second transport unit are each a continuous transport element, that is to say a continuous one Conveyor belt, exhibit. This may for example be divided by corresponding deflection rollers which are arranged along the extension of the conveyor belt in the transport direction.
  • the transport units each or together comprise at least one further transport element, which can be applied to further edges, in particular to the lower edges of the sheet-like products.
  • This embodiment is advantageous in that the flat products in a desired region of the transport device can be held or supported in addition to the holder at its side edges in addition to, for example, at the lower edge. This is particularly advantageous for very wide or extremely heavy sheet products. This advantage is also noticeable in lightweight products, when there is a high transport speed at which it has been shown that the sheet-like products tend to vibrate. This is reduced by the applicable to the lower edge of the sheet products further transport element. If conveyor belts are accelerated with products held therebetween, tilting movements can take place, in particular in the case of asymmetrical products, due to the inertial mass, which can thus be avoided.
  • transport elements are conceivable within the scope of this invention, which can be applied to the upper edge or to the upper edge and the lower edge of the sheet-like products.
  • the additional arrangement of an attachable to the lower edge further transport element is particularly advantageous for the first transport unit, but may also extend partially exclusively in the second transport unit, extend completely in this or only in the region of the second Transport unit, depending on the direction in which the products are to be stored.
  • the device further comprises a slider which is movable at least perpendicular to the transport direction and arranged movable against an upper edge of the sheet-like products.
  • This embodiment has the advantage that the sheet-like products can be transferred by such a slide in the corresponding transport container. This preferably takes place after sorting. Furthermore, this slider is preferably arranged in the region of the second transport unit, if present. The slider can thereby transfer the flat products to be transferred solely by a movement in the direction of gravity, ie from top to bottom in the transport container or cooperate with the preferred embodiment of the mutually variable transport elements of the second transport unit. So can be achieved by a timed interaction that the sheet products are transferred as a coherent package in the transport container, instead of just falling out of the apart transporting elements of the second transport unit due to gravity. By the latter variant can occur by tilting the sheet products in or on the transport container, a mixing or tilting.
  • the slider is additionally arranged movable in the transport direction.
  • This embodiment is advantageous in that the slider instead of simply just perform a vertical movement, in addition can still go with the flat products in the transport direction. As a result, on the one hand, an even more continuous transition of the flat products into the transport container allows. On the other hand, in a preferably present stop element that, seen in the transport direction, is arranged at the end of the transport container, a pushing or even compressing the sheet-like products are achieved before they are transferred vertically downwards into the transport container.
  • the device further comprises a control unit, by which at least the transport units are controllable.
  • both the process of sorting and the transfer of the sheet products are coordinated in the transport container allows. Furthermore, this also preferably controls the feeding of the flat products into the first transport unit, the transition of the flat products from the first to the second transport unit and changing the transport elements of the second transport unit and the actuation of the slide for transferring the flat products into the transport containers. In addition, a control of the transport container, preferably their replacement, carried by the control unit.
  • control unit is designed to divide data from the feeder or from one of the feeder upstream or from a unit connected to it and, on the basis of this data, divide the products into separate groups of products in the device, spaced apart along the transport direction are separated.
  • This embodiment has the advantage that the device according to the invention can thus carry out the steps in an automatic manner, which were previously carried out by a sorting person mentioned at the outset, if necessary in cooperation with a marking by a separate machine with a scanner.
  • the control unit is thus able to obtain, by means of a scanner or a camera, data from either the inserter, the feeder, a unit present between inserter and feeder, or from the apparatus itself, and to pass on corresponding control commands to the transport units on the basis of these data.
  • these data can either already be prepared accordingly or else be evaluated by the control unit itself.
  • the products For sorting the products within the first transport unit, according to the invention, provision is made for the products to be divided into separate groups. This can be done simply by varying the transport speed. If, for example, a desired number of products has been taken in succession, the transport speed can be increased for a short time, so that a distance to the next product is created. This always results in packages of sheet-like products, which can be transported further within the device and finally transferred to a respective transport container.
  • the subdivision into groups with interspaces or intervals arranged therebetween has the further advantage that a simultaneous transport of several groups or parcels within the first transport unit in the transport direction is possible, while only a single such parcel can be present in the second transport unit.
  • This can then be converted into a respective transport container by corresponding changes to the second transport unit described above independently of the packages and groups in the first transport unit. This is preferably done with a previously described slide.
  • the delivery of the sheet-like products is carried out individually or in small packages and the sheet-like products in the transport unit are transported parallel to one another and arranged one behind the other at an arbitrary distance, as seen in the transport direction.
  • This embodiment has the advantage that, referring to the embodiment described in connection with the device, the flat products can already be transported individually or in small packages so that they can be easily transferred into a corresponding transport container in this arrangement. This is given by the parallel and seen in the transport direction successively arrangement. That's because the Transport containers are usually designed so that the corresponding flat products in the transport containers just just such an arrangement.
  • the provision of transporting at any desired distance from one another has the advantage that the flat products can continue to be arranged evenly and parallel to one another between the transport elements during transport in the at least one transport unit, irrespective of whether they contain products which may carry heavy loads on one side.
  • a distance can always be chosen according to any, so that in particular the criteria in parallel and behind each other can be met.
  • the insertion of the distances has a short-term increase in the transport speed of the transport elements between the reception of two flat products from the feed.
  • This embodiment is a preferred way how the separation can be made within the first transport unit.
  • this step would then proceed in such a way that the flat products already accommodated in the first and second transport unit, which are generally always advanced with a slight feed in the transport direction when a new sheet product is picked up by the feeder, are present the picking up of a new sheet product are clearly moved away from this in the transport direction.
  • This fast feed leads to a distance of preferably several centimeters. This makes it possible that a sufficient distance is available to weed out the correspondingly previously recorded in the device flat products without affecting the subsequent sheet products from the at least one transport unit in corresponding transport container.
  • This embodiment essentially has the advantages already described above in connection with the second transport unit of the device.
  • the continuous transfer of the sheet-like products also has the advantage that no separate stopping and transferring of the flat products into the second transport unit or, for example, a transport container is necessary.
  • a separation is possible that both supply of the sheet products in the transport units and separating the sheet products in transport containers, preferably after the division into groups, take place without these two processes disturb or impair.
  • this method step represents the concluding step.
  • the flat products have arrived in groups sorted in the second transport unit and are then separated into corresponding transport containers for further processing or forwarding, for example to the letter delivery company.
  • This device 10 has a feed 12, a first transport unit 14 and a second transport unit 16. This is especially the representations of Fig. 1 and Fig. 6 refer to.
  • the feeder 12 receives flat products 18 in the form of envelopes, as they are described in more detail in particular in connection with the following figures, from an inserter not shown here.
  • this inserting machine serves to transfer machine-printed letters into envelopes and to close them, and then generally delivers them lying horizontally on a conveyor belt as shown in FIG Fig. 1 out. So they get into the feeder 12 according to a feed direction shown there by an arrow 30.
  • the feeder 12 further comprises a conveyor belt 32.
  • This conveyor belt 32 receives the sheet-like products 18 from the feed direction 30 and moves them according to his in Fig. 1 to be recognized curved course in a standing position. There they are received by a linear conveyor 34.

  • the envelopes 20 of the group 71 are pushed against the stop 88. This is preferably done after the holding contact between the transport elements 64 and 66 and the envelopes 20 of the group 71 has been removed, as has already been described in more detail above.
  • a division of envelopes 20, which are lined up within a transport unit 14, 16 can be performed in groups.
  • the stop 86 is moved in a vertical movement corresponding to the double arrow 84 between two envelopes 20, between which the separation is to take place.
  • this method is also suitable for devices which have, for example, only one transport unit 14, 16, or generally no separation into groups 71, as will be described in more detail below.
  • the device 10 additionally has a control unit 100 in this embodiment.
  • This control unit 100 is used to control in particular the transport units 14 and 16, but preferably also of the entire device 10. This is indicated by an arrow 102.
  • the control unit 100 controls, for example, the separation of envelopes 20 into different groups 72, as will be described below in more detail in connection with FIGS Fig. 7a to 7f is described.
  • the control unit 100 receives data from any unit 104 for this purpose.
  • This unit 104 can itself be part of the device 10. Furthermore, it is conceivable that this is a component of a machine 10 upstream of the machine, which is not shown here, is. This can be, for example, the inserting machine mentioned above.
  • the unit 104 includes a data acquisition device 106, which may be, for example, a camera or scanner not shown in detail herein.
  • This data acquisition device 106 transmits the acquired data to the unit 104, which then forwards this data to the control unit 100 itself. This is illustrated by arrows 108 and 110. Alternatively, the data may also be forwarded directly from the data acquisition device 106 to the control unit 100, which is indicated here by an arrow 112.
  • the data thus transmitted in each case can reach the control unit 100 as raw data, which then converts these into corresponding control data or else is previously converted into corresponding data to be used by the control unit 100 either in the unit 104 or also in the data acquisition device 106.
  • control unit 100 controls the transport unit 14 and preferably also the transport unit 16 in such a way that it controls the transport speed of the transport elements 54 and 56 or 54, 56, 64 and 66.
  • FIG. 7a an initial situation is shown in which four envelopes 21 to 24 are already accommodated at their side edges 19 and 19 'by transport elements 54' and 56 ', shown schematically here, in a transport unit 14'.
  • Another envelope 25 is still here in the feed 12 'and is, as determined by the transition from Fig. 7a 7b is also received in the transport unit 14 'between the transport elements 54' and 56 '.
  • Thereupon another envelope 26 moves into the feed 12 '.
  • this envelope 26 is received in the transport unit 14 ', as determined by the transition of Fig. 7b to 7c, whereupon another envelope 27 follows.
  • This sequence of receptacles in the transport unit 14 ' represents the normal case for receiving envelopes in a transport unit 14, 14' according to the present invention.
  • the transport elements 54 'and 56' are briefly moved faster in the direction of transport direction 52. This takes place before the envelope 27, which is no longer part of the group 72 ', is received in the transport unit 14', that is to say between the transport elements 54 'and 56'.
  • This faster movement, or acceleration, of the transport elements 54 'and 56' can be initiated by the control unit 100, for example.
  • This has, for example, from the data acquisition device 106 or the unit 104 according to the previously made statements information or data obtained that cause a separation between the envelope 26 and envelope 27.
  • This data may be, for example, information about postal code areas, such that, for example, between envelopes 26 and 27 there is a change in the postal code areas. The division into these separate postal code areas is due to specific Specifications or agreements between the letter-sender and the mail-order company.
  • These distances between the groups, here 72 'and 72 "and the envelope 28, designated by reference numerals 114 and 114', may be identical or different, depending on the desires and configurations of the device 10 and preferably the control unit 100 ,
  • the further transport of the groups 72 ', 72 ", etc. now takes place in accordance with the statements made above and leads according to the method and the previous description of a first transport unit 14 in preferably a second transport unit 16.
  • the first Group 72 'are transferred by releasing the envelopes 21 to 26 of the transport elements 64 and 66 in a transport container 74 and would thus correspond to the previously described group 71. This is done without affecting the subsequent groups 72 ", etc., preferably still in a first Transport unit 14 and 14 'are located.
  • the transfer into the transport container 74 preferably takes place by means of a slide 78, 78 'in accordance with the statements made above.
  • groups 71 ', 71 ", etc. described above are shown as small groups of six or fewer envelopes, and this is especially to be applied to larger quantities of envelopes as will occur in normal use of the device 10.
