Description

Logistics storage operation system based on cloud computing

Technical Field

The invention relates to the field of logistics, in particular to a logistics storage operation system based on cloud computing.

Background

Among the ten electronic commerce enterprises in the world, the Chinese enterprise occupies four seats. The e-commerce market in china is still rapidly developing at present. Electronic commerce logistics, as a link for connecting buyers and sellers, plays an important role in improving customer satisfaction and becomes a key for the success of electronic commerce. The explosive growth of e-commerce orders places higher demands on logistics, and is a real challenge for e-commerce logistics providers, particularly in promotional campaigns. Similarly, warehousing of e-commerce logistics also faces challenges, such as those created by increasing inventory size, increasing customer service requirements, decreasing inventory requirements, increasing warehouse operational efficiency requirements, space utilization, and environmental changes. The electronic commerce storage is mainly characterized by small order quantity and multiple batches. Warehousing issues should be dynamically considered by continuously integrating new information about the operating environment, such as new management concepts and new information technologies, to meet market demands. Automated solutions are used to solve this problem, but automated and unattended warehousing solutions have many limitations.

The storage is the connection point of each important logistics node, so that the production, storage, transportation, sale and other links are started, and the main contradiction among all key nodes in a logistics system is also concentrated. Therefore, the management of the storage nodes is the key point of the management of the whole-course logistics system, is the key point of realizing the automation and the informatization of the logistics so as to improve the quality and the efficiency of the whole-course logistics, and is the fundamental starting point of limiting and reducing the circulation cost. In addition, industrial robots are key factors for improving the performance of logistics warehouses. One of the main problems of logistics warehouses is the industrial robot planning problem, which consists in determining the best industrial robot capable of performing all the requested tasks within a given time interval at the lowest total cost. Industrial robot planning greatly affects the performance of multi-tasking robot warehousing operation systems. Moreover, for special types of products, such as plate-type materials, the prior art generally adopts a stacked manner for storage, which occupies a large space and is inconvenient for personalized and customized access requirements.

Disclosure of Invention

The technical problem to be solved by the invention is to overcome the existing defects, and provide a logistics storage operation system based on cloud computing, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

the invention discloses a logistics storage operation system based on cloud computing, which transmits information streams to each other through a cloud computing platform, a logistics distribution system and a sales system, the logistics storage operation system based on cloud computing is used for transmitting information streams to each other through the cloud computing platform, the logistics distribution system and the sales system, and the logistics storage operation system based on RFID in a warehouse has the following processes: at the infeed conveyor, an RFID reader is provided for collecting RFID information data for each incoming and outgoing truck RFID-tagged cargo passing through the warehouse. When a particular load is required, it can be automatically transferred from the rack to the output conveyor by the moving assembly 30. Each mobile assembly also contains an RFID reader that provides an antenna that receives wireless signals transmitted from each RFID tag item in the rack. The inventory data collected by the card reader is immediately updated in the warehouse management system by the master control system which transmits the collected data through the conversion device. The conversion device is a software conversion layer between the RFID reader and the warehouse management system.

The database of the logistics warehouse operating system contains data in the identification, availability and other usage defining information of each item stored in the warehouse. Once a user orders an in-store item, the RFID-based inventory management system can automatically check the information data for the item in the database. Once the RFID-based inventory management system identifies the ordered item, the programmable logic controller PLC will activate the moving assembly 30 to push the selected item in the rack onto the output conveyor. The given item will then be transported by the output conveyor and packaged along the RFID-guided route to the given destination. The RFID-based warehouse inventory database will be updated immediately once ordered goods are trucked out of the distribution center through the gates of the warehouse entry/exit. The whole process is carried out automatically without any human intervention, except for the necessary operations of opening boxes, labelling and packaging in the warehouse.

In a warehouse, items are tracked and manipulated by an RFID-based inventory management system after being tagged with RFID tags. The RFID tags have unique identification and other custom information related to the status of each item. RFID tags consist of two main components, namely an antenna and a computer chip. The computer chip stores data and the antenna allows data communication between the RFID tag and the RFID reader via wireless signal transmission. The RFID reader is a microcontroller-based radio transceiver that uses the time-varying electromagnetic field generated by the RFID antenna to power the RFID tag.

The RFID information data collected by the RFID reader may be transmitted to a database for data processing and storage. By using RFID tags, the goods can be randomly distributed anywhere in the rack and, as such, the goods can be randomly delivered to different delivery locations in the warehouse. This greatly facilitates storage, retrieval and replenishment operations and improves the capacity, flexibility and responsiveness of the warehousing system to store and deliver items.

The logistics warehousing operation system automatically performs an inventory search process for the ordered items by executing a set of predefined selection rules, including an availability check for each ordered item, a location of the ordered item, a shortest path for the ordered item to reach a designated collection point, a validity period for each ordered item, and other user-defined selection criteria. If an item is selected from a group of items of the same type stored at multiple locations in the warehouse, the logistics warehousing operation system will prioritize the selected item according to predetermined selection rules and initiate a need to push the selected item onto the output conveyor.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 18, the present invention provides a logistics storage operation system based on cloud computing, which performs mutual transmission of information flow with a logistics distribution system and a sales system through a cloud computing platform, wherein the logistics storage operation system based on RFID in a warehouse has the following processes: at the infeed conveyor, an RFID reader is provided for collecting RFID information data for each incoming and outgoing truck RFID-tagged cargo passing through the warehouse. When a particular load is required, it can be automatically transferred from the rack to the output conveyor by the moving assembly 30. Each mobile assembly also includes an RFID reader that is configured with an antenna that receives wireless signals transmitted from each RFID tag item in the rack. The inventory data collected by the card reader is immediately updated in the warehouse management system by the master control system which transmits the collected data through the conversion device. The conversion device is a software conversion layer between the RFID reader and the warehouse management system.

The database of the logistics warehouse operating system contains data in the identification, availability and other usage defining information of each item stored in the warehouse. Once a user orders an in-store item, the RFID-based inventory management system can automatically check the information data for the item in the database. Once the RFID-based inventory management system identifies the ordered item, the programmable logic controller PLC activates the moving assembly 30 to push the selected item in the rack onto the output conveyor. The ordered goods will then be transported by the output conveyor and packaged along the RFID guided route to the intended destination. The RFID-based warehouse inventory database will be updated immediately once ordered goods are trucked out of the distribution center through the gates of the warehouse entrance/exit. The whole process is carried out automatically without any human intervention, except for the operations of opening, labelling and packaging in the warehouse.

In a warehouse, items are tracked and manipulated by an RFID-based inventory management system after being tagged with RFID tags. The RFID tags have unique identification and other custom information related to the status of each item. An RFID tag consists of two main components, namely an antenna and a computer chip. The computer chip stores data and the antenna allows data communication between the RFID tag and the RFID reader via wireless signal transmission. The RFID reader is a microcontroller-based radio transceiver that uses the time-varying electromagnetic field generated by the RFID antenna to power the RFID tag.

Referring to fig. 2, the logistics warehousing operation system automatically performs an inventory search process for the ordered items by executing a set of predefined selection rules, including availability checks for each ordered item, location of the ordered item, shortest path for the ordered item to reach a specified collection point, expiration date for each ordered item, and other user-defined selection criteria. If an item is selected from a group of items of the same type stored at multiple locations in the warehouse, the logistics warehousing operation system will prioritize the selected item according to predetermined selection rules and initiate a need to push the selected item onto the output conveyor.

Logistics storage operating system includes: the main control system is used for identifying each plate introduced into the warehouse and matching each plate with one accommodating space;

at least one frame 20 having a plurality of side plates 21 parallel to each other and aligned in the longitudinal direction Y. Each side plate 21 is configured as a plane substantially perpendicular or slightly inclined with respect to the vertical plane, allowing at least one sheet L to be supported on one side and arranged at a small inclination with respect to the vertical plane. Each side plate 21 is configured to support at least one plate placed on one side and slightly inclined so as to place another plate material on the side plate 21 slightly inclined with respect to the vertical direction.

And a lower bracket 23 on which the plate material L is disposed, an upper surface of the lower bracket being inclined downward in a direction of the respective side plate 21. One or more side panels 21 arranged adjacent to two side panels 21 form a storage space 22. The first sheet L is laid against the side plate 21, and other sheets L contained in the same storage space 22 are placed on the first sheet L in succession to each other. The plate L farthest from the side plate 21, i.e. the last plate L in the group on the same side plate 21, is a plate L that can be picked and placed, and the plate L can be picked and placed by the clamping device. The inclination of the sheets L at the same side plate 21 increases slightly from the first to the last sheet, but still close to the vertical direction. The sheets L are not stacked together and are placed side by side in a near vertical orientation. Thus, the number of sheets that can be stored using the racks 20 is much greater than would be allowed in a conventional warehouse, while occupying the same surface area.

At least one moving assembly 30 is movable along the gantry 20 along a direction parallel to the longitudinal direction Y. The moving assembly 30 comprises a gripping device 31 for taking and placing at least one sheet material L in the storage space 22. In addition, the moving assembly 30 has at least one bracket 32 configured to allow at least one sheet L to be placed on the moving assembly 30. The rack 32 supports the sheet L in a position similar to that of the sheet L in the storage space 22, i.e., in a position inclined to a nearly vertical plane. The moving assembly 30 moves along the housing 20 to reach any of the storage spaces 22. The holding device 31 can put the sheet L in the storage space 22. To introduce the sheet L into the storage space 22, the gripping device 31 is moved to the position of the transfer apparatus 1 and the sheet L is picked up by the gripping device 31 and placed on the rack 32. The clamping device 31 may sequentially pick up a predetermined number of the sheets L placed on the rack 32. After loading is complete, the moving assembly 30 moves along the rack 20 to the storage space 22 provided for each sheet material. At each storage space 2 provided, the gripping device 31 picks up the accessible sheets L placed on the rack 32 and places them in the storage space 22. Similarly, if a certain number of sheets L are to be removed, the moving assembly 30 will move continuously to each storage space 22, loading the sheets L onto the rack 32 by means of the gripping device 31. Once loading is complete, the moving assembly 30 reaches the unloading position corresponding thereto, and the shuttle moving assembly 30 continues to unload the sheet L by means of the gripping device 31. The combination of the rack 20 and the moving assembly 30 thus allows the slabs L to be handled in a very simple and effective manner when entering and leaving the warehouse.

The logistics warehouse work system comprises a main control system arranged to identify each sheet L introduced into the warehouse and to match each identified sheet L with a housing space 22. The main control system also controls the operation of the movement assembly 30, directing it to a specific storage space 22, in which the sheets L are placed or picked up. Therefore, the operation of storing and taking out the plate materials L can be automatically managed.

The main control system is equipped with different functional modules, each responsible for controlling a specific device or operating cycle. The main control system may consist of a single electronic device programmed to perform the functions described, and the different functional modules may correspond to hardware entities and/or software routines forming part of the programmed device. Alternatively or additionally, the functions may be performed by a plurality of electronic devices, and the functional modules may be distributed over the electronic devices.

The clamping device 31 comprises a robot 33, which robot 33 moves a clamping head 34 in space for taking and placing at least one sheet L. The robot 33 is in the form of an articulated arm with six axes of rotation. A robot 33 is mounted on the moving assembly 30. The clamping head 34 comprises a set of suction cups, the clamping surfaces of which are arranged on a plane so as to be able to adhere to the surface of the sheet L. The robot 33 is provided with joints allowing to move the gripping head 34 in space and to rotate the gripping head 34 between at least a substantially vertical position and a substantially horizontal position. In the substantially vertical position of the gripper head 34, the robot 33 can pick up or release the sheet L on the storage space 22 or on the rack 32. The gripper head 34 is equipped with position and orientation sensors that assist the robot 33 in controlling the gripper head 34 in order to facilitate correct access to the sheet L to be picked up or in order to place a subsequent sheet L. In order to avoid excessive sliding between the sheet L already positioned and the sheet L to be unloaded, the robot 33 performs the following release phase: the sheet L to be unloaded is initially placed on the lower side, keeping a predetermined distance from the positioned sheet L. After the support is completed, the sheet L to be unloaded is tilted toward the positioned sheet L and then released.

The robot 33 may also be in a holding position in which the gripper head 34 holds at least one sheet L in place on the carriage 32. In this way, the robot 33 may be used as a method of stabilizing the sheet L during movement of the moving assembly 30. The holding position substantially corresponds to a position where the clamping head 34 grips or releases the sheet material L placed on the holder 32. Before each movement of the moving assembly 30, the robot arm 33 positions the clamping head 34 in a position in contact with the accessible sheet material L of the plate pack located on the carriage 32. If the displacement of the moving assembly 30 occurs after the loading of the sheet L on the carriage 32, the clamping head 34 remains in contact with the sheet L just loaded on the carriage 32. If the moving assembly 30 is moved after unloading the sheet material L, the robot 33 moves the gripper head 34 onto the rest of the plates on the carriage 32, accessible to the sheet material L, before the moving assembly 30 is activated.

To facilitate the insertion of the gripping means 31, the side panels 21 can be moved independently of each other in the longitudinal direction Y to allow temporary enlargement of each storage space 22. By way of example, an enlarged storage space 22e is shown to facilitate access to the holding device 31. To this end, the side plates 21 are slidingly associated with a base 24, the base 24 being arranged inclined on the ground. The movement of the side plate 21 in the longitudinal direction Y is effected by a motor movement mechanism. The displacement of the side panels 21 is regulated by the main control system of the warehouse, so that the side panels 21 of the storage space 22 intended to receive or supply the sheets L are widened to allow the access of the gripping devices 31 or gripping heads 34. In order to limit the number of side plates 21 that move simultaneously, the frame 20 may be divided into side plates 21 driven by separate motor mechanisms.

In order to increase the capacity of the automated warehouse, the second rack 20 may be arranged parallel to the longitudinal direction Y and the first rack 20. In this case, the moving assembly 30 may move between the first rack and the second rack along a corridor parallel to the first rack and the second rack. The holding device 31 is able to enter the storage space 22 of the two racks 20 located on opposite sides of the moving assembly 30.

The two moving assemblies 30 may be placed along the same aisle between the two racks 20 and moved along the same track. In this case it is advantageous to place the loading position at one end of the corridor and the unloading position at the other end of the corridor. The first moving assembly 30 is responsible for introducing the sheet L into the rack, taking it out of the loading position and bringing it to the respective storage space 22. The second moving assembly 30 is responsible for taking the sheet L from the rack, taking it out of the storage space 22 and guiding it to the unloading position in the manner described above. The operation of the two moving assemblies 30 is coordinated by the main control system of the warehouse and does not interfere with each other.

By arranging a plurality of racks 20 side by side in parallel, the capacity of the warehouse can be increased as desired. One or two mobile assemblies 30 are placed in each aisle between two adjacent racks 20. Each mobile assembly 30 is managed by the master control system in the manner described above. The automatic warehouse comprises an entrance section 40 equipped with a transport plane 41 for introducing the slabs L into the warehouse.

The transport plane 41 comprises at least one entrance terminal 42 located at the entrance end of the path travelled by the mobile assembly 30, in a position accessible by the gripping means 31. The entrance terminal 42 is a branch of the conveying surface 41 and comprises a conveying device consisting of two or more motorized belts. The belt is arranged between the rollers of the transport plane 41, can be lifted above the support surfaces defined by the rollers to pick up the sheet L, lift it by the rollers themselves, or lowered below the support surfaces defined by the rollers to allow the sheet to pass through L. The entrance terminal 42 is provided with the transfer device 1, the transfer device 1 transfers the horizontally transported and stacked plates in the direction, so that the moving assembly 30 can quickly grab the plates for subsequent storage, and the transfer device 1 is arranged at one end of a corridor along which the moving assembly 30 can move. When the movement assembly 30 is positioned at the transfer device 1 of the access terminal 42, the gripping means 31 are able to reach the sheets L arranged on the terminal 42, to load them on the supports 32 and guide them to the prefixed storage space 22.

In an embodiment comprising a plurality of racks 20 and a plurality of terminals 30 arranged between adjacent racks 20, the transport plane 41 is provided with a plurality of terminals 42, each terminal 42 being located at an entrance end of the path of one of the mobile assemblies 30, or at an entrance end of a corridor through which the mobile assemblies 30 pass.

The inlet section 40 can be equipped with control means 43 for the qualitative control of the sheets L in transit on the plane of conveyance 41 and to identify sheets L not having the predetermined characteristics as waste. The control means 43 is arranged to detect surface defects, deformations or breaks in the sheet L in transit, for example.

Downstream of the control device 43, the transport plane 41 is equipped with an evacuation section 44 designed to remove the sheets L as waste from the control device 43. The evacuation section 44 also takes the form of a branch of the transport plane 41, through a conveyor comprising two or more motorized belts, arranged between the rollers of the transport plane 41, which can be lifted above the support surface defined by the rollers to pick up the sheet L, lifted by the rollers themselves, or lowered below the support surface defined by the rollers to allow the sheet to pass through L.

The logistics warehouse operation system comprises an outlet section 50 equipped with a transport plane 51 for extracting the slabs L from the warehouse. The conveying plane 51 is a motorized roller conveyor. The transport plane 51 comprises at least one exit terminal 52, which terminal 52 is located at the exit end of the path travelled by the mobile assembly 30, in a position accessible by the gripping means 31. The outlet terminal end 52 is a branch of the transport surface 51, obtained by deviation means comprising two or more motorized belts, arranged between the rollers of the transport surface 51, which can rise above the surface support of the rollers to pick up the sheet L and lift it from the rollers, or below the support plane defined by the rollers, to allow the passage of the sheet L.

The terminal 52 is disposed at one end of a hallway along which the mobile assembly 30 can move. When the moving assembly 30 is located at this terminal end, the gripping means 31 are able to pick up the sheet L placed on the support 32 and position it on the terminal end 52, guiding it from the terminal end 52 to the transport plane 51.

In an embodiment comprising a plurality of racks 20 and a plurality of mobile assemblies 30 arranged between adjacent racks 20, the transport plane 51 is provided with a plurality of terminals 52, each terminal 52 being located at an exit end of the path of one of the existing mobile assemblies 30, or at an exit end of a corridor through which one mobile assembly 30 passes.

In the embodiment shown, there are two output terminals 52 both entering the transport plane 51. The sheets taken from the racks 20 by the different moving assemblies 30 are sequentially transferred to the terminal 52 in the order determined by the warehouse master control system and from the terminal 52 to the transport plane 51, always in the order determined by the warehouse master control system.

Since the outlet portion 50 is controlled by the main control device, the outlet of the sheet L from the warehouse can be automatically managed. The sheets L are arranged in succession on the conveying plane 51 according to the predetermined packages to be made.

The outlet portion may be equipped with a packing device 60 for picking up the sheets L from the transport plane 51 and arranging the sheets L in predetermined packages each comprising two or more sheets. The packaging unit 60 comprises an arm 61, the arm 61 being equipped with a gripping head adapted to grip the sheet L arranged on the transport plane 51 of the outlet portion. The arm 61 is movable between a gripping area on the transport plane 51 and one or more packaging positions P, in which it releases each sheet L picked up. The packaging locations may be equipped with various packaging aids such as cartons, trays or other types of containers. The wrapping device 60 is controlled by the main control device to arrange the sheets L in a predetermined order in the predetermined wrapping position P.

The packaging unit 60 can also be equipped with a plugging machine 62 designed to insert one or more shock-absorbing pouches between the sheet L and the packaging wall, especially in the case where the latter is made of wooden boxes or other material. The shock-absorbing bag is composed of a closed self-expanding soft envelope. The plugging machine 62 includes an insertion head 63 that is movable between various packaging positions P to introduce the dunnage bags into the various packages.

Furthermore, the packaging unit 60 is equipped with a strapping machine 64 for tensioning one or more straps arranged in the package around each finished package and/or individual sheet L.

In addition, the transfer device 1 comprises a first station 3 for automatically storing the panels 2, the panels 2 being provided with a storage 4 for accommodating the panels 2. The storage section 4 comprises movable side walls 8, a fixed rear wall 15 and a front movable wall 16, the fixed rear wall 15 being formed of a straight portion and an inclined portion to facilitate positioning of the sheet 2 in the storage section 4.

The side wall 8 comprises a slot and the side wall fixing means 9 fix the side wall 8 by screws through the mounting slot. The side walls 8 slide the same length as the slots. After being mounted in place, the side walls 8 are fixed to the storage section 4 by tightening the screws. The bottom of the storage portion 4 can be opened to take out the sheet 2 from the bottom. The storage section 4 also comprises a small protrusion 17 at the bottom to prevent the sheets 2 from falling due to gravity and to allow the lateral removal of only one sheet 2. The transfer device 1 further comprises a pick-and-place device 6.

The transfer apparatus 1 also comprises a second station 5 suitable for receiving each sheet 2 taken from the store 4 and allowing it to interface with the movement assembly 30. The second station 5 also comprises rototranslation means 7 of the pick-and-place means 6 for moving each sheet 2 from the store 4 to the second station 5. The pick-and-place device 6 for fixing the sheet 2 comprises a pneumatic suction device 12 connected to a source of negative pressure. Preferably, the pneumatic suction means 12 is a suction cup.

The pick-and-place device 6 rotates the suction plate 10 in a synchronized manner. The suction plates 10 are of different sizes to accommodate the different sizes of sheet material 2 used each time. Two suction plates 10 are generally used, one for one side region of the sheet and the other for the other side region of the sheet. The suction plate 10 is driven by first hinge arms 11, and the first hinge arms 11 rotate about respective rotation axes. The hinge arm 11 connects the plate 10 with a second hinge arm 11', the second hinge arm 11' being connected to the slide 14. The two suction plates 10 are moved simultaneously to ensure that they do not contact each other when rotated. In addition the suction plate 10 is moved in a synchronized rotational manner for separation from the sheet material 2.

The roto-translating means 7 comprise a support element 13, the support element 13 rotating between a first position, shown in figure 3, in which the pick-and-place means 6 of the sheet material 2 are directed towards the open bottom of the storage 4, and a second position, in which the pick-and-hold means 6 are directed towards the storage 4. Said rototranslation means 7 comprise at least one slide 14 that is linearly movable with respect to said support element 13 between a retracted position and an advanced position. The first advanced position corresponds to the gripping zone of the sheet from the bottom of the store 4 and the second advanced position corresponds to the position in which the sheet 2 is in abutment with the moving assembly 30, i.e. in the first advanced position the support element 13 is aligned with the store 4 and in the second advanced position it coincides with the abutment zone of the moving assembly 30. The retracted position corresponds to the top position, translating in the translation direction of the slide 14.

The first drive means 18 are located at one side of the transfer device 1 and drive the pick-and-place means 6. The first driving means 18 rotate the supporting element 13, through the connecting

shafts

26, 27, 28, to two desired positions corresponding to the storage 4 and to the zone of abutment of the moving assembly 30. The second drive means 24 move the slider 14 sliding with respect to the support element 13 on the guide 24', moving it from the rear position to the top position.

The working process of the transfer equipment is as follows: the sheets 2 of various sizes transported by the terminal end 42 of the transport plane 41 are loaded into the storage 4 using the movable side walls 8 and the fastening means 9 of the storage to lock the sheets 2 stored in the storage 4. The rotation of the supporting element 13 and therefore of the slide 14 is activated, reaching the first position in which the pick-and-place device 6 of the sheet material 2 is directed towards the bottom of the opening of the storage 4. The pick-and-place device 6 picks up the single sheet 2 and moves, rotates and translates it to a second position in which the pick-and-place device 6 faces the second station 5 for docking the sheet 2 with the moving assembly 30. After docking, during the transition from the top position to the retracted position, the pneumatic suction means 12 are deactivated and the rotation of the extraction means articulated arms 11, 11' is activated and the pick-and-place means 6 are driven in order to rotate the suction plate 10 in order to remove the docked sheet 2, so that the pneumatic suction means 12 are then reactivated and the

slides

13, 14 are rotated back to the first position of the pick-and-place means 6 of the sheet 2 towards the open bottom of the storage 4, ready to pick up a new sheet 2. To sum up, the first station 3 is supplemented with a storage section 4 for refilling the transfer sheets 2, each sheet 2 is then taken out of the storage section 4 by the pick-and-place device 6, and after being picked up from the storage section 4, the sheet 2 is held by the pick-and-place device 6; then, the sheet material is moved from the first station 3 to the second station 5 for transferring the sheet material by the rotary translation device 7, and after the sheet material 2 at the second station 5 is received by the moving assembly 30, the transferred sheet material 2 is separated from the pick-and-place device 6.
