Description
DK 180533 B1 eStacker for pallets The present invention relates to an eStacker for pallets, where the stacker is for stacking and unstacking pallets resting on each other in a vertical stack, where the stacker comprises a framework with at least a first side, a second side and a back, where the framework is intended for disposition with three side edges of a pallet, where the lifting frame is driven by an electrical lifting mechanism and moveable vertically up and down along the framework, and where the lifting frame at the first side and the second side comprises a gripper arrangement driven by an electrical engagement mechanism, where each gripper arrangement comprises at least one gripper plate which is movable arranged between a position for engaging a pallet and a position for disengaging a pallet.
The present invention also relates to methods, a computer program product and the use of the said eStacker.
PRIOR ART Before the development of the present invention, it was known to store pallets in stacks as e.g. disclosed in EP0587929A1 where pallets are removed from or added to the bottom or top of an erectable stack which is vertically displaced in a three-sided frame by two hydraulic cylinders.
JPH 11292287 A discloses a stacker for loading and unloading pallets, comprising a frame structure with a back side and two opposite sides defining a space for placement of the pallets. The stacker further comprises a lifting frame connected to an electrical lifting mechanism arranged on the frame structure, wherein the lifting mechanism can move the pallets vertically up and down using grippers. The
> DK 180533 B1 grippers comprise gripper plates that are able to move in and out of engagement with a respective pallet. One of the disadvantages of this is the use of hydraulic cylinders as hydraulic systems are unwanted in many places due to environmental or hygiene issues. Another one of the disadvantages of this known system is the lack of safety devices in order to prevent failures during operation. Hydraulic systems usually have hose break and/or stop valves to prevent the systems from collapsing.
Many stackers or pallet magazines are pneumatic, which in terms of energy is an even worse solution than hydraulics. Similarly, solutions with actuators are also known in many cases to result in short and/or poor durability. Regarding safety aspects in pneumatic systems, the systems are often dangerous due to the lack of safety arrangements. The present invention differs from the prior art technology by using clean energy in terms of electricity and in having anti-crash devices ensuring that no harm is done to neither pallets nor stacker.
OBJECT OF THE INVENTION The object of this invention is therefore to provide a stacker of the type mentioned in the introduction which uses clean energy in terms of electricity making it useable in a wide range of industries. It is a further object of the invention to provide a stacker which improves the working environment e.g. due to far less noise than pneumatic and hydraulic systems.
2 DK 180533 B1 It is an even further object of the invention to provide a stacker with anti-crash devices ensuring that no harm is done to pallets or stacker.
DESCRIPTION OF THE INVENTION According to a first aspect of the invention, the above object is achieved with an eStacker of the type mentioned in the introduction, where the gripper arrangement comprises a first wheel for moving the gripper plate into position for engaging a pallet and a second wheel for moving the gripper plate into position for disengaging a pallet, where the gripper plates are movable about an axis of rotation and where the first wheel and the second wheel are placed at opposite sides of a wobble plate arranged at a rod and where the first wheel via a spring is spring-loaded. This makes it possible to operate a stacker only using clean energy where the stacker is able to conduct a method of stacking and unstacking pallets. In a preferred embodiment is the eStacker an integrated safety-shielded unit where the vast majority of moving parts are not accessible during operation due to the use of coverplates.
In another aspect, the present invention also relates to an eStacker, where the first side and the second side of the lifting frame comprises a wall part, where the wall part at the first side is facing the wall part at the second side and where the wall parts are intended for disposition at opposite side edges of a pallet.
This makes it possible to hold the pallets at two sideedges between the wall parts when stacking and unstacking, hence avoiding the sliding of pallets up and down the sides of the frame work.
In a preferred embodiment the top of the wall parts is at least the same as the top of the stacker.
1 DK 180533 B1 In another aspect, the present invention also relates to an eStacker, where the electrical lifting mechanism comprises a sprocket driven by an electrical motor and gear unit, where the sprocket is connected to a shaft with a first end being off- centre of the sprocket and where a second end of the shaft is connected to the lifting frame, the first end being able to conduct rotational motion and the second end of the shaft being able to conduct linear motion. This makes it possible to lift and lower the lifting frame in a preferred embodiment by means of a sprocket driven by a chain which is driven by an electrical motor. An alternative embodiment could be a pulley driven by a toothed belt which is driven by an electrical motor.
An even further alternative embodiment could be a V-belt pulley driven by a belt which is driven by an electrical motor. Other embodiments based on friction could also be alternatives. In an even further embodiment a wheel could be directly driven by a motor and gear unit.
The rotational motion may be either clockwise or anticlockwise, and it may change between clockwise and anticlockwise in any way. The rotational motion may also run "endlessly" meaning that a cycle can be run on a lap in the same direction either clockwise or anticlockwise.
The sprocket is driven around an axle on which axle a plate/wheel/disk is also situated and where between the sprocket and the plate/wheel/disk the first end of the shaft is arranged off-centre.
In an alternative embodiment, the first end of the shaft could be arranged at the periphery of the sprocket, which would also ensure rotational motion.
på DK 180533 B1 In another aspect, the present invention also relates to an eStacker, where the second end of the shaft is connected to the lifting frame in a crash-safe bolt-slot connection, where at least one bolt is able to move within the slot if the lifting frame is blocked.
This makes it possible to avoid crashing of the electrical lifting mechanism, either in a direct connection with the lifting frame or in an indirect connection with the lifting frame.
In case of a blockage the bolt will then be able to move within the slot, hence avoiding crashing of the electrical lifting mechanism. In a preferred embodiment the slot is in the shaft and closer to the second end of the shaft than the first end of the shaft. The bolt/bolts are thus passing through the slot in the shaft and the bolts are connected to the lifting frame. Using an indirect connection the slot is in the shaft which is in the middle of the connection, where at both sides of the shaft there is a distance part and then another shaft which is connected with the rest of the lifting frame in a rotary joint.
In a further preferred embodiment the bolts are secured and tensioned at both sides of the shaft to the lifting frame via coupling means, where the coupling means being able to conduct rotational motion on the lifting frame and being able to conduct linear motion at the crash-safe bolt-slot connection.
It is also possible to avoid crashing of the electrical lifting mechanism by means of a sensor which sends signal to the control for stopping the machine in case of a blocking occurs.
In an optimal solution the eStacker is equipped with both the sensor crash-safe arrangement and the bolt-slot crash-safe arrangement.
på DK 180533 B1 In another aspect, the present invention also relates to an eStacker, where the electrical engagement mechanism is arranged at the lifting frame and where the electrical engagement mechanism comprises a sprocket driven by an electrical motor and gear unit, where the sprocket is arranged at the rod where the wobble plate is connected to the gripper arrangement at both the first side and at the second side of the lifting frame. This makes it possible to operate the gripper arrangements between a grip (engaging position) and a non-grip position (disengaging position) ensuring that the gripper arrangement at either side is in the same grip or non-grip position. In a preferred embodiment the sprocket is driven by a chain which is driven by an electrical motor.
An alternative embodiment could be a pulley driven by a toothed belt which is driven by an electrical motor. An even further alternative embodiment could be a V-belt pulley driven by a belt which is driven by an electrical motor. Other embodiments based on friction could also be alternatives. In an even further embodiment could a wheel be directly driven by a motor and gear unit. The rotational motion may be either clockwise or anticlockwise, and it may change between clockwise and anticlockwise in any way. As mentioned earlier, the gripper arrangement comprises at least one gripper plate which is movable arranged between a position for engaging a pallet and a position for disengaging a pallet, where the gripper arrangement comprises a first wheel for moving the gripper plate into position for engaging a pallet and a second wheel for moving the gripper plate into position for disengaging a pallet, where the gripper
, DK 180533 B1 plates are movable about an axis of rotation and where the first wheel and the second wheel are placed at opposite sides of the wobble plate arranged at the rod and where the first wheel via a spring is spring-loaded.
This makes it possible to avoid crashing of the electrical engagement mechanism, because the spring-loaded wheel gets into force in case there is a blockage of the gripper arrangement, that is, if the gripper arrangement is not able to move into position for engagement. A blockage of the gripper could happen in case a pallet was not yet brought into final position in the stacker or a misplacement happened.
In another aspect, the present invention also relates to an eStacker, where the lifting frame further comprises ball bearings arranged perpendicular to each other in pairs suitable to move vertically up and down joints provided between the first side, the back and the second side of the framework, where at least two pairs of ball bearings are arranged at either joint. This makes it possible to ensure a fully controlled vertical movement along the frame work, where the lifting frame cannot get out of track and cause a stand-still of the stacker.
In a preferred embodiment two pairs of ball bearings are arranged at either joint, where the pairs are at approximately the same horizontal level and further there are two pairs of ball bearings arranged at either joint vertical below each other. Hence, there are optimally four pairs of ball bearings ensuring a controlled movement. In another aspect, the present invention also relates to a method of stacking pallets in an eStacker, where the stacking at least comprises the following steps: e putting a pallet or stack of pallets into a correct position in the stacker,
8 DK 180533 B1 e lifting frame is driven to a disengaging position in which a pre-loaded pallet or stack of pallets are resting on the pallet or stack of pallets to form a combined stack, e gripper plates are moved into a disengaging position, e lifting frame is driven to a bottom position, e gripper plates are moved into an engaging position with the lowest pallet of the combined stack, e lifting frame is driven to a top position.
With this method it is possible, with the pallet stacker comprising a lift mechanism, which is disposed to lift the lower pallet one or more pallet heights as desired in engagement with two opposite side edges of a pallet for enabling upstacking of pallets, to build up the stack from beneath.
In another aspect, the present invention also relates to a method of unstacking pallets in an eStacker, where the de-stacking at least comprises the following steps: e lifting frame is driven to a bottom position, e gripper plates are moved out of an engaging position with a lowest pallet of the stack and into a disengaging position, e lifting frame is driven to an engaging position relative to a second lowest pallet of the stack or a lower pallet of an upper stack, e gripper plates are moved into an engaging position with the second lowest pallet of the stack), e lifting frame is driven to a top position, e removing the lowest pallet. With this method it is possible, with the pallet stacker comprising a lift mechanism, which is disposed to engage two opposite side edges of a second lowest pallet of a stack for lifting a pallet and those pallets, which are situated above the pallet, at o DK 180533 B1 least one pallet height, to enable the removal of the lowest pallet of the stack and thus downstacking from beneath.
In another aspect, the present invention also relates to a method of placing a stack of pallets in an eStacker, where the placing of a stack at least comprises the following steps: e an operator puts the stack of pallets correctly in the stacker, e lifting frame is driven to bottom position, e gripper plates are moved into an engaging position with a lower pallet of the stack, e lifting frame is driven to top position. With this method it is possible, with the pallet stacker comprising a lift mechanism, which is disposed to lift the lower pallet one or more pallet heights as desired in engagement with two opposite side edges of a pallet, to enable placing a stack of pallets, when building up the stack from beneath In another aspect, the present invention also relates to a method of removing a stack of pallets in an eStacker, where the removal of a stack at least comprises the following steps: e lifting frame is driven in bottom position, e gripper plates are moved out of an engaging position with a lower pallet of the stack and into a disengaging position, e lifting frame is driven to top position. e an operator removes the stack. With this method it is possible, with the pallet stacker comprising a lift mechanism, which is disposed to engage two opposite side edges of a second lowest pallet of a stack for lifting a pallet and those pallets, which are situated above the pallet, at
DK 180533 B1 10 least one pallet height, to enable the removal of the lower stack of pallets and thus downstacking from beneath. In another aspect, the present invention also relates to a computer program product comprising instructions to cause the eStacker to execute the steps of the methods. This makes it possible to automate the methods and to obtain a better and more efficient utilisation of the stacker capability.
In another aspect, the present invention also relates to a use of an eStacker for square or rectangular sized pallets. This makes it possible to stack and unstack pallets categorized as CHEP (Commonwealth Handling Equipment Pool) which is a well-defined size of pallets. However, the eStacker could be constructed to any other kind of square or rectangular pallet-size.
