DETAILED DESCRIPTION OF THE INVENTION
(16) Basically, in the figures, the same parts are provided with the same reference numerals.
(17) Certain features are not represented in the figures for the purpose of a better understanding of the invention. The embodiment examples that are described hereinafter are merely exemplary for the subject-matter of the invention and have no limiting effect.
(18)
(19) The bag feed appliance 10 includes a stack guide 17, in which a stack 11 of flatly folded-together carrier bags 2 is arranged in a lying manner. The stack 11 lies in the stack guide 17 on a stack support (rest) 19 which is designed as a conveying belt. The conveying belt permits the active refeed of the stack 11 towards a bag removal location 21.
(20) The stack 11 or the stack support 19 is inclined slightly obliquely downwards towards the bag removal location 21. The inclination assists in the active re-feeding of the stack 11 towards the bag removal location 21.
(21) The stack 11 is supported at its rear flat side by a support member 22. The stack 11 is further also laterally supported by lateral support members 20. The lateral support members 20 are each designed as a conveying belt in this embodiment example. These likewise assist in the active refeed of the stack to the bag removal locations.
(22) The front flat side of the stack 11 is likewise supported on the bag removal location 21, but in a manner such that this permits the removal of individual carrier bags 2 from the stack 11.
(23) The bag feed appliance 10 further includes a suction gripper 12 with several suction heads for removing individual carrier bags 2 from the stack 11. The suction grippers 12 can be moved between the stack 11 and the grippers 31 of the first conveying appliance 30 (see movement arrows) via a movement mechanism (not shown).
(24) The first conveying appliance 30 is a suspended conveyor and includes a multitude of conveying units each with a conveying vehicle 32 as well as with a gripper 31 which is arranged on the conveying vehicle 32.
(25) The conveying vehicles 32 include runner rollers (not shown), by way of which the conveying vehicle 32 rolls along a guide rail 34. The guide rail 34 forms a closed circulating track for the conveying units.
(26) A conveying screw 35 is arranged in the transfer region 13, wherein this conveying screw is rotatably mounted about a rotation axis and by way of which empty conveying units are conveyed into a transfer position in the transfer region 13 in a controlled manner for the purpose of taking over flatly folded-together carrier bags 2.
(27) For this, a spirally or helically designed guide groove 36, which serves for receiving and for driving a catch lug (not shown), which is arranged on the conveying vehicle 32 is arranged along the outer periphery of the conveying screw 35.
(28) The catch lug engages into the guide groove 36 and together with the conveying unit is caught or driven along the rotation axis of the conveying screw 35 and conveyed into the transfer region 13 by way of the guide groove 36, which rotates with the conveying screw 35, for conveying the conveying unit into the transfer region 13.
(29) A release station 37, which interacts with a control 39, is arranged upstream of the conveying screw 35 considered in the conveying direction F.
(30) Individual conveying units are released, which is to say freed into the transfer region 13, in particular in a cycled manner, by way of the release station 37.
(31) The release station 37 includes a retaining element, which can be switched by the control 39 and by way of which the conveying units are held back upstream of the transfer region 13 considered in the conveying direction F. Individual conveying units are released into the transfer region 13 by way of switching the retaining element between a retaining position and a release position.
(32) Furthermore, an accumulation stretch, in which conveying vehicles 32 with empty grippers 31 are accumulated is formed upstream of the release station 37 considered in the conveying direction F. The accumulation stretch runs along a descent.
(33) In each case, a conveying unit is released into the transfer region 13 by way of the release station 37 for the transfer of folded-together carrier bags 2 to empty grippers 31 of the first conveying appliance 30. Furthermore, the suction gripper 12 of the bag feed appliance 10 is led to the front flat side of the stack 11. This with its suction heads grips the frontmost carrier bag 2 at its free flat side.
(34) The suction gripper 12 pulls the gripped carrier bag 2 from the stack 11 and transports this to the open gripper 31 of the conveying unit in the transfer region 13 (see movement arrows). The suction gripper 12 introduces the flatly folded-together carrier bag 2 with an upper bag section into the open gripper jaw of the gripper 31. The gripper 31 is closed and grips the carrier bag 2 in a suspended position.
(35) As soon as the gripper 31 has gripped the carrier bag 2, the suction gripper 12 detaches itself again from the carrier bag 2 and moves back to the stack 11 for the purpose of gripping and removing a next carrier bag 2 from the stack 11 (see movement arrows). A new transfer cycle begins.
(36) The conveying units can be released into the transfer region 13 individually or in groups. Accordingly, individual grippers 31 or a group of grippers 31 can be fed with carrier bags 2 in the transfer region 13.
(37) Subsequently to the take-over of the carrier bags 2, the conveying units in the suspended position are moved in the conveying direction F out of the transfer region 13 by way of the conveying screw 35. Consequently, the conveying units, which are charged with the folded-together carrier bags 2, are conveyed to a bag opening appliance 51 in a suspended manner.
(38) If a group of conveying units are to be fed with carrier bags 2 in the transfer region 13, then in particular the conveying units are also fed in groups to the bag opening appliance 51. The number of conveying units of a group of conveying units hereby corresponds in particular to the number of carrier bags 2, which in the opening region 66 are to be transferred to an individual loading and transport container 3.
(39) The already mentioned bag opening appliance 51 according to
(40) The bag opening appliance 51 includes a conveying screw 61, which is rotatable about a rotation axis and by way of which conveying units with flatly folded-together carrier bags 2 are conveyed into an opening position in the opening region 66 in a controlled manner.
(41) For this, a spirally or helically designed guide groove 62, which serves for receiving and driving a catch lug (not shown), which is arranged on the conveying vehicle 32, is arranged along the outer periphery of the conveying screw 61.
(42) For conveying a conveying unit in the opening region 66, the catch lug engages into the guide groove 62 and together with the conveying unit is caught along the rotation axis of the conveying screw 61 and conveyed into the opening position by way of the guide groove 62, which rotates with the conveying screw 61.
(43) A release station 60 is arranged upstream of the conveying screw 61 considered in the conveying direction F, the release station interacting with the control 39.
(44) Individual conveying units are released or freed into the opening region 66 in a controlled, in particular cycled manner by way of the release station 60.
(45) The release station 60 includes a retaining element, which can be switched by the control 39 and by way of which the conveying units can be held back upstream of the opening region 66 considered in the conveying direction F. Individual conveying units are released or freed into the opening region 66 by way of switching the retaining element between a retaining position and release position.
(46) Furthermore, an accumulation stretch, in which conveying units with folded-together carrier bags 2 can be accumulated, is formed upstream of the release station 60 considered in the conveying direction F.
(47) The flatly folded-together carrier bags 2 are conveyed into the opening region 66 in the suspended position and are opened.
(48) The opening of the carrier bags 2 in the opening region 66 is effected in a two-step opening method.
(49) For this, the bag opening appliance 50 includes a separating mechanism 51. This includes a first suction gripper 53 and a second suction gripper 55, which lie opposite this, each with at least one first and at least one second suction head 54, 56 respectively, the suction heads being directed towards one another. Both suction grippers 53, 55 form a receiving gap for a carrier bag 2.
(50) The suction grippers 53, 55 are arranged on a carrier mount (see
(51) The suction grippers 53, 55 are movably mounted via a movement mechanism. The suction grippers 53, 54 can be moved towards the carrier bags 2 in the opening position by way of the movement mechanism, in a manner such that the carrier bags 2 each come to lie between the first and the second suction gripper 53, 55.
(52) In the present embodiment example, three carrier bags 2 are opened in groups and are transferred to a loading and transport container 3.
(53) Accordingly, three carrier bags 2 are conveyed in the bag opening appliance into opening positions, which are arranged next to one another.
(54) The separating mechanism 51 then includes three pairings of first and second suction grippers 53, 55, which have been mentioned above and which are moved towards the carrier bags 2 in a manner such that the carrier bags 2 each come to lie between a first and a second suction gripper 53, 55 of a suction gripper pairing.
(55) The suction grippers 53, 55 are moved towards one another amid the reduction of the receiving gap between the suction grippers 53, 55 for carrying out a first opening step. Basically, also only one of the suction grippers 53, 55 can be moved to the opposite suction gripper 53, 55.
(56) The suction grippers 53, 55 approach the front and rear wall 4a, 4b of the carrier bag 2 and grip these with their suction heads 54, 56 which act upon the bag walls 4a, 4b and hold these.
(57) The carrier bags 4a, 4b are released from the grippers 31 of the first conveying appliance 30 after the suction grippers 53, 55 have gripped the carrier bags 4a, 4b. The carrier bags 2 are consequently only then held by the suction grippers 53, 55.
(58) The suction grippers 53, 55 are connected to a vacuum generator 65 for producing a vacuum (see
(59) After gripping the bag walls 4a, 4b, the suction grippers 53, 55 are moved away from one another again amid the enlargement of the receiving gap, by which means both bag walls 4a, 4b are separated from one another while releasing a bag opening 18 or at least one opening gap (see also
(60) An active means 59 can now act into the bag interior 5 through the released bag opening 18 or through the opening gap, for the purpose of carrying out the second opening step. The active means 59 is part of an active means mechanism 52.1.
(61) The second opening step includes the complete opening or unfolding of the carrier bag 2.
(62) According to the embodiment example according to
(63)
(64)
(65) The opening plunger 63 is now led with the rollers 64 towards the bag base 6. As soon as the opening plunger 63 has reached its opening position in the bag interior 5, the rollers 64 are pivoted out laterally, by which means the bag front wall and bag rear wall 4a, 4b are pressed outwards and the bag base 6 is folded out and the carrier bag 2 is folded open. The rollers 64 are pivoted laterally in the proximity of the base 6 so that the unfolding of the bag base 6 can indeed be effected in a reliable manner.
(66)
(67) The conveying units are moved out of the opening region 66 by way of the conveying screw 61 subsequently to the opening and the transfer of the opened carrier bags 2 to the loading and transport containers 3, and are conveyed in the conveying direction F along the closed conveying stretch back into the transfer region 13.
(68)
(69) The conveying unit includes a schematically represented conveying vehicle 32, as is also represented in the embodiment example according to
(70)
(71) What is represented is a feed conveyor 71 for feed conveying empty loading and transport containers 3 to a merging appliance 70. The feed conveyer 71 forms a conveying surface for the loading and transport containers 3 in the form of a roller support.
(72) The feed conveyor 71 forms an accumulation stretch for holding back empty loading and transport containers 3 upstream of the merging appliance 70. The empty loading and transport containers 3 are individually fed to the merging appliance 70 by way of a release station 72.
(73) Individual, empty loading and transport containers 3 are conveyed in the conveying direction G onto a support member 73 of the merging appliance 70 for bringing the carrier bags 22 into the loading and transport containers 3. In the present embodiment example, the support member 73 is designed as a conveying belt and permits the active conveying of the loading and transport container 3 on the support member 73.
(74) The support member 73 is coupled onto a lever mechanism 74, by way of which this together with the loading and transport container 3 can be lifted to the opening region 66 of the bag opening appliance 50 for the purpose of receiving carrier bags 2, and lowered again.
(75) The lifting mechanism 74 is designed as a pivoting arrangement, by way of which the support member 73, pivoting about a pivot axis 76, can be lifted to the bag opening appliance 50. A lift member 75 with a lift cylinder is arranged below the support member 73 for carrying out the pivoting movement, the lift cylinder being designed to lift the support member 73 from below and to lower it again (double arrow).
(76) The support surface of the support member 73 has an inclination in the initial position, in which the empty loading and transport containers 3 are moved from the feed conveyor 71 onto the support member 73 and in which loading and transport containers 3 with carrier bags 2 are transferred from the support member 73 onto the second conveying appliance 80.
(77) The support surfaces of the feed conveyor 71 and of the second conveying appliance 80 are likewise inclined and are flush, which is to say aligned with the support surface of the support member 73. The descent of the inclined support surfaces is towards the conveying direction G, so that the loading and transport containers 3 can be conveyed in the conveying direction G on the roller support of the feed conveyor 71 or of the second conveying appliance 80 in a manner assisted by gravity.
(78) The support member 73, by way of the lifting mechanism and with this the loading and transport container 3 on the support member 73, is lifted upwards towards the opening region 66 for the purpose of bringing the still flatly folded-together carrier bags 2 into the loading and transport container 2 in the opening region 66 of the bag opening appliance 50.
(79) In this manner, the carrier bags 2 are positioned with their previously freely suspended base-side bag section in the loading and transport container 3 in the opening region 66.
(80) The carrier bags 2 are subsequently completely opened in the loading and transport container 3 by way of the two-step opening method, which has already been described above.
(81) After opening the carrier bags 2, these are released again from the suction grippers 53, 55 and the support member 73 is lowered again by way of the lifting mechanism 74. Accordingly, the loading and transport containers 3 together with the carrier bags 2, which are opened therein, are lowered out of the opening region 66 back into the initial position.
(82) The second conveying appliance 80 is a roller conveyor with a roller support 81 for the loading and transport containers 3. As soon as the support member 73 has assumed its initial position again, the loading and transport containers 3 with the opened carrier bags 2, which are contained in these, are moved onto the roller support 81 of the second conveying appliance 80 by way of the conveying belt of the support member 73 and subsequently conveyed further with the second conveying appliance 80, e.g. along an order-picking stretch.
(83)
(84) The carrier bag 2 includes a bag front wall 4a, a bag rear wall 4b as well as two bag side walls 7a, 7b. The bag side walls 7a, 7b form the short sides of the carrier bag 2. The carrier bag 2 further includes a bag opening 18, which leads into the bag interior 5. The bag opening 18 serves for filling the carrier bag 2 with goods 1.
(85) The carrier bag 2 further includes two carrier handles 8 for carrying the carrier bag 2, of which a first carrier handle 8 is fastened to the bag front wall 4a and a second carrier handle 8 is fastened to the bag rear wall 4b. The carrier handles 8 can be folded over into the bag interior (see
(86) The carrier bag 2 further includes a bag base 6, which in the folded-together state of the carrier bag 2 is folded over to the bag front wall 4a or bag rear wall 4b (see
(87) Longitudinally running fold lines 9, along which the carrier bag 2 can be folded together are arranged in the bag side walls 7a, 7b.
(88)
