TECHNICAL FIELD
[0001] The present application relates to the technical field of machining tool storage and retrieval equipment, in particular to a tool magazine for vertically storing and retrieving tools. BACKGROUND
[0002] With the increasing variety of machining tools, the increasing amount of tools, and the increasing frequency of tool use, people have increasingly high requirements for the automation of tool magazine management.
[0003] There are many types of tool magazines or tool cabinets in the prior art, with different structures, each having its own advantages and disadvantages.
[0004] For example, some tools are stored or retrieved vertically, such as numerical control tools. The tool magazine for vertically storing and retrieving tools in the prior art directly inserts the vertically stored tools into the tool holes of the storage plates of the several layers of the three-dimensional magazine and stores or retrieves them through the retrieval system. The tool can only be moved horizontally, i.e. retrieved, after being lifted from the tool hole by a certain height and having the bottom end of the tool higher than the top end surface of the tool hole, and the mechanical gripper itself and the operation also require a considerable height space. It is not difficult to understand that such a structure is at the cost of reducing the number of layers of vertically stored tools in a unit space, i.e. the number of stored tools in a unit space is reduced by a geometric multiple. Moreover, although the control system of the tool magazine in the prior art can receive the input of the mobile phone remote control to the input end of the control system with respect to the tool information, if multiple tools are needed to be retrieved at one time, the tool magazine in the prior art still needs to be manually placed at the tool retrieval position to wait for the retrieval system of the tool magazine to run the required tools one by one from different storage spaces of the tool magazine to the tool retrieval position, which requires a long waiting time. Conversely, if multiple tools need to be stored at one time, the tools need to be manually placed one by one at the tool retrieval position, and the retrieval system of the tool magazine needs to be waited for to take away the tools, then the second tool needs to be placed, and the retrieval system of the tool magazine needs to be waited for to run the tool to the predetermined tool hole of the predetermined storage plate in the predetermined storage space, and then the above operation needs to be repeated to store the second tool. The waiting time for multiple tools to be retrieved or stored at one time is too long, and this technical problem has not been well solved in the technical field of tool magazines in the prior art. SUMMARY
[0005] The technical problem to be solved by the present application is to provide a tool magazine for vertically storing and retrieving tools, which can greatly reduce the height required during the storage or retrieval of tools in a vertical state, greatly increase the number of tools stored in the tool magazine, and greatly reduce the waiting time of people when multiple tools need to be retrieved or stored at one time.
[0006] The technical solution of the present application is to provide a tool magazine for vertically accessing tools, comprising a storage system, a taking and placing system and a control system; the storage system comprises two vertically symmetrical grid-shaped storage libraries, the storage spaces of each vertical grid-shaped storage library are equally spaced in each column and each row, and the entrances and exits of all the storage spaces are towards the middle of the two vertical grid-shaped storage libraries; the horizontal driving mechanism, vertical lifting mechanism and bidirectional telescopic forks of the taking and placing system are arranged in the middle of the two vertical grid-shaped storage libraries.
[0007] A pair of horizontal supporting plates for supporting a rectangular tool disc are fixed on the four first vertical columns of each storage space, a plurality of tool hole seats are arranged on each rectangular tool disc, and a large-small conical hole on each tool hole seat is used for accommodating a large-small conical body of a vertical state tool.
[0008] The sliding plate of the bidirectional telescopic fork of the taking and placing system is a first H-shaped plate with an opening upwards, which is matched with the shape of the bottom of the rectangular tool disc and leaves a downward extending height of the vertical state tool.
[0009] The taking and placing system further comprises a circular chain conveying mechanism and a tool transfer mechanism for taking the vertical state tools from the tool disc transferred from the bidirectional telescopic fork and placing them on the circular chain conveying mechanism, or taking the vertical state tools from the circular chain conveying mechanism and placing them in the tool hole seats of the rectangular tool disc transferred from the bidirectional telescopic fork.
[0010] The circular chain conveying mechanism is located at one end of the two vertical grid-shaped storage libraries, and vertically forwards and backwards conveys the vertical state tools between the tool transfer mechanism and the tool manual taking and placing place; the tool transfer mechanism is located at the rear side of the inner end of the circular chain conveying mechanism.
[0011] After adopting the above structure, the tool magazine for vertically accessing tools has the following advantages:
[0012] Since the rectangular tool disc with a plurality of tool hole seats is used to store a plurality of vertical state tools, when the rectangular tool disc is taken or placed, the top surface of the first H-shaped plate of the bidirectional telescopic fork only needs to support the bottom surface of the rectangular tool disc, and slightly moves upwards or is directly placed horizontally, so that the tool disc with vertical state tools can be moved out of the storage space, and the tool disc only needs to be placed in the reverse direction, that is, the bottom surface of the tool disc is slightly higher than the horizontal supporting plate, so that the process of taking out or storing the vertical state tools does not require additional height space, and the taking and placing system itself and the operation also do not require additional height space, and only a small gap between the top and bottom ends of the tools is required between the layers, so that the number of layers of the tool disc can be doubled or multiplied, and the number of stored vertical state tools such as vertical state stored numerical control tools can be doubled or multiplied in the same storage space.
[0013] Also, when multiple tools are needed at one time, the information of the multiple tools needed can be sent to the input end of the tool library control system in advance on the mobile phone, and the main controller of the control system controls the taking and placing system to arrange the required tools on the ring chain conveying mechanism of the taking and placing system in turn, i.e. on the tool seats of the ring chain conveying mechanism as described below, so that the ring chain conveying mechanism can temporarily store multiple vertical tools, and after a person arrives at the manual tool taking and placing place, only needs to input the required tool information at the input end of the tool library, and then the required tools can be taken out one by one, such as from the tool seats of the manual tool taking and placing place as described below, which greatly reduces the waiting time of the person for taking multiple tools, such as 2-3 seconds for taking one tool, and less than 1 minute for taking multiple tools such as 10 tools at one time, and the waiting time is almost negligible. The same is true for storing multiple tools at one time, only needs to input the tool information to be stored at the input end of the tool library, such as scanning the two-dimensional code on the tool to be stored by using the code scanner connected with the main control system of the control system, and then inserting the tools in turn into the multiple tool seats of the ring chain conveying mechanism as described below, and the person can leave and basically does not need to wait during the process of storing the tools. The technical problem of long waiting time for taking and placing multiple tools at one time in the technical field of the tool library of the prior art is solved.
[0014] Further, the tool transfer mechanism includes a bottom plate fixed with the vertical grid-shaped storage library, two side plates for vertical guide rails and a vertical first drive cylinder fixed on the bottom plate, the free end of the piston rod of the vertical first drive cylinder is connected with a second H-shaped plate which is open upward and has two inwardly curled edges at the top and is used for placing a rectangular tool disc, the two side plates constitute a sliding cavity for the upward and downward sliding of the second H-shaped plate with two inwardly curled edges; the top of the two side plates has a pair of clamping plates driven by respective transverse second drive cylinders and used for clamping the rectangular tool disc; the bottom plate is also provided with a transfer device for bidirectional conveying of vertical tools between the clamped rectangular tool disc and the ring chain conveying mechanism. After adopting the above structure, the tool disc in the sliding cavity formed by the two side plates can first enter the bottom layer and then rise to the transfer device operation layer, so that the tool transfer process can be continuously carried out, thereby effectively ensuring that the horizontal drive mechanism, the vertical lifting mechanism, the bidirectional telescopic forks upstream of the transfer mechanism and the ring chain conveying mechanism downstream can continuously, stably and smoothly operate, and further ensuring the technical effects of greatly increasing the tool storage quantity and greatly reducing the waiting time of the person for storing multiple tools at one time.
[0015] Further, the transfer device comprises a second vertical column fixed on the bottom plate, a horizontal guide rail mounted on the top end of the second vertical column and perpendicular to the first horizontal drive structure at the end of the vertical grid-shaped storage, a second horizontal drive mechanism perpendicular to the first horizontal drive structure on the first horizontal drive structure, a vertical lifting structure on the second horizontal drive structure, and a pneumatic gripper on the free end of the lifting rod of the vertical lifting structure, which is radially opened and closed and used to grab or release the vertical state tool. After adopting the above structure, the transfer device can smoothly and reliably operate during the tool taking or storing operation between the tool disc and the ring chain conveying mechanism, further ensuring the technical effects of greatly increasing the tool storage quantity and greatly reducing the waiting time for taking or placing multiple tools at a time.
[0016] Further, the ring chain conveying mechanism comprises a bracket at one end of the two vertical grid-shaped storages, a rectangular top plate extending from front to back on the top of the bracket, a tool manual taking and placing position at the front end of the rectangular top plate, and a tool taking and placing position of the transfer device of the tool intermediate transfer mechanism at the rear end of the rectangular top plate. The ring chain conveying mechanism further comprises a driving sprocket and a driven sprocket rotatably fitted on the rectangular top plate, and a ring chain meshed on the driving sprocket and the driven sprocket. The outer side of the ring chain is fixed with a plurality of tool seats for accommodating and conveying the vertical state tools. After adopting the above structure, the ring chain conveying mechanism not only serves as a part of the taking and placing system, enabling the taking and placing process of the vertical state tools to be smooth, flexible, stable and reliable, but also serves as a temporary storage point for manual tool taking and placing, enabling a plurality of vertical state tools to be temporarily stored at a time, further ensuring the technical effects of greatly increasing the tool storage quantity and greatly reducing the waiting time for taking or placing multiple tools at a time.
[0017] Further, the ring chain is a runway-shaped ring chain extending in the front-rear length direction. The outer side of each tool seat has a horizontal roller, the rear end of the rectangular top plate has a clamping block driven by a third driving cylinder and clamping the tool seat for inserting the vertical state tool or releasing the tool seat so that the tool seat can rotate with the ring chain, and the free end of the clamping block has a semicircular notch matched with the horizontal roller. After adopting the above structure, the structure and layout of the ring chain conveying mechanism are more reasonable, and the relative positioning of the tool seat is realized by the mutual clamping of the clamping block and the horizontal roller during the process of inserting the vertical state tool into the center hole of the tool seat or taking the vertical state tool from the tool seat, enabling the taking and placing process of the vertical state tool to be faster, more stable and more reliable, and further ensuring the technical effect of greatly reducing the waiting time for taking or placing multiple tools at a time.
[0018] Further, the two sides of the rectangular top plate each have a guide plate parallel to the straight section of the endless chain, the rolling surface of the horizontal roller rolls on the vertical guide surface of the guide plate, the length of the guide plate is equal to or greater than the length of the straight section of the endless chain, and the two ends of the guide plate have inclined surfaces to facilitate the rolling surface of the horizontal roller to fit the vertical guide surface of the guide plate. After adopting the above structure, the straight section of the chain with multiple or several tool holders is prevented from being inclined, the endless chain conveying mechanism is always in a flexible, stable and reliable running state, and the technical effect of greatly reducing the waiting time for manually taking or placing multiple tools at a time is further ensured.
[0019] Further, the tool holder includes a support seat composed of a horizontal plate and two vertical plates, the inner vertical plate of the two vertical plates has a plurality of holes for screwing and fixing with the endless chain, the top of the outer vertical plate is lower than or equal to the top surface of the horizontal plate, a horizontal roller is installed in the middle of the width of the upper part of the outer vertical plate, and two vertical rollers for rolling on the top surface of the rectangular top plate are installed on both sides of the lower part of the outer vertical plate. After adopting the above structure, the endless chain conveying mechanism is always in a flexible, stable and reliable running state, and the technical effect of greatly reducing the waiting time for manually taking or placing multiple tools at a time is further ensured.
[0020] Further, the tool holder includes a support seat composed of a horizontal plate and two vertical plates, the inner vertical plate of the two vertical plates has a plurality of holes for screwing and fixing with the endless chain, the top of the outer vertical plate is lower than or equal to the top surface of the horizontal plate, a horizontal roller is installed in the middle of the width of the upper part of the outer vertical plate, and two vertical rollers for rolling on the top surface of the rectangular top plate are installed on both sides of the lower part of the outer vertical plate.

Detailed Implementation
[0039] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings. It is to be understood that the description of the specific embodiments is intended to help understand the present application, but does not constitute a limitation of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0040] As Figures 1-17 indicated.
[0041] The tool magazine of the vertical access tool includes a storage system, a taking and placing system, and a control system. The storage system includes two vertically symmetrical grid-shaped storage magazines 12, and multiple vertical access tool storage spaces 9 of each vertical grid-shaped storage magazine 12 are evenly distributed in each column and each row, and the entrances and exits of all storage spaces 9 are towards the middle of the two vertical grid-shaped storage magazines 12. The horizontal driving mechanism 17, the vertical lifting mechanism 13, and the bidirectional telescopic fork 71 of the taking and placing system are arranged in the middle of the two vertical grid-shaped storage magazines 12. In other words, for each vertical grid-shaped storage magazine 12, the entrances and exits of all storage spaces 9 are on the inner side, also known as the horizontal driving mechanism 17, the vertical lifting mechanism 13, and the bidirectional telescopic fork 71 of the taking and placing system in the middle, that is, the entrances and exits of all storage spaces 9 are oppositely arranged.
[0042] As Figure 3 , Figure 4 , Figure 5 indicated, a pair of horizontal supporting plates 7 for supporting a rectangular tool disc 10 are fixed on the four first vertical columns 8 of each storage space 9, and multiple tool hole seats 11 are arranged on each rectangular tool disc 10, such as twelve tool hole seats 11 arranged in four rows and three columns on each rectangular tool disc 10. The large-small conical hole on each tool hole seat 11 is used to accommodate the large-small conical body of the vertical state tool 6. It is not difficult to understand that every four first vertical columns 8 of each vertical grid-shaped storage magazine 12 constitute a column of multiple storage spaces 9 in the vertical direction, and each pair of two horizontal supporting plates 7 constitute a layer or a storage space 9, as Figure 3 indicated, five layers or five storage spaces 9 can be arranged, and each storage space 9 has a rectangular tool disc 10. The horizontal supporting plate 7 can be made of angle steel. It is not difficult to understand that since the vertical state tool such as a numerical control tool also extends at the bottom of the tool disc, each storage space 9 not only accommodates the vertical state tool 6 above the rectangular tool disc 10 itself, but also accommodates the downward extending part of the vertical state tool 6 of the rectangular tool disc 10 of the upper storage space 9.
[0043] As Figure 17The sliding plate of the two-way telescopic fork 71 of the pick-and-place system is a first H-shaped plate 72 with its bottom opening upward and matching the shape of the bottom of the rectangular tool tray 10 and leaving a space for the downward extension of the vertical state tool 6. The sliding plate of the two-way telescopic fork 71 is also called a moving plate.

The free end of the piston rod of the vertical first driving cylinder 20 is connected to a second H-shaped plate 28 with its top opening upward and having two inwardly curled edges for resting the rectangular tool tray 10. The second H-shaped plate 28 can be composed of a rectangular plate and two H-shaped plates with their openings inward symmetrically arranged on both sides and connected by a plurality of screws. A connecting disc 31 can be provided on the free end of the piston rod of the first driving cylinder 20 and fixed with the rectangular plate of the second H-shaped plate 28 by a plurality of screws. The two side plates 22 form a sliding cavity for the upward and downward sliding of the second H-shaped plate 28 with the two inwardly curled edges. The top of the two side plates 22 has a pair of clamping plates 33 driven by respective transverse second driving cylinders 32 and used for clamping the rectangular tool tray 10. The bottom plate 27 is also provided with a transfer device 29 for bi-directionally conveying the vertical state tool 6 between the clamped rectangular tool tray 10 and the circular chain conveying mechanism 15. It is not difficult to understand that, in order to enhance the connection firmness of the two side plates 22 and the bottom plate 27 and the strength of the two side plates 22, a plurality of first reinforcing plates 21 can be fixed on the outer sides of the two side plates 22 and the bottom plate 27, such as two first reinforcing plates 21 on the outer side of each side plate 22 and the bottom plate 27.
[0048] The transfer device 29 can include a second vertical column 30 fixed on the base plate 27, a first horizontal drive structure 25 installed on the top end of the second vertical column 30 and perpendicular to the horizontal bar 16 at the end of the vertical grid-shaped storage 12, a second horizontal drive structure 24 perpendicular to the first horizontal drive structure 25, and a vertical lifting structure 26 on the second horizontal drive structure 24. The free end of the lifting bar of the vertical lifting structure 26 has a radial opening and closing air claw 34 for grabbing or releasing the vertical state tool 6. For example, the two claws of the air claw 34 can hold the horizontal circular groove of the vertical state tool 6, and can also be released in the opposite direction.

The ring chain conveying mechanism 15 also includes a driving sprocket 37 and a driven sprocket 39 rotatingly fitted on the rectangular top plate 35, and a ring chain 38 engaged with the driving sprocket 37 and the driven sprocket 39. The driving sprocket 37 can be driven by a motor such as a driving sprocket motor 50 fixed on the bottom surface of one end of the rectangular top plate 35. The motor shaft of the driving sprocket motor 50 extends upward through the through hole in the rectangular top plate 35 and is fixed with the horizontal driving sprocket 37 on the upward extending portion. The driven sprocket 39 is arranged at the other end, i.e. the front end, of the rectangular top plate 35. The outer side of the ring chain 38 is fixed with a plurality of tool seats 5 for accommodating and conveying the vertical state tools 6. The plurality of tool seats 5 can be, for example, ten, dozens, and dozens of tool seats 5.
[0051] The ring chain 38 is preferably a ring chain 38 extending in the front-rear length direction and in the shape of a running track for movement. The outer side of each tool seat 5 has a horizontal roller 49, and the rear end of the rectangular top plate 35 has a clamping block 46 driven by a third driving cylinder 47 and clamped to the tool seat 5 for inserting the vertical state tool 6 or releasing the tool seat 5 so that the tool seat 5 can rotate with the ring chain 38. In other words, the rear end of the rectangular top plate 35 has a third driving cylinder 47, and the free end of the piston rod of the third driving cylinder 47 is fixed with a clamping block 46. The clamping block 46 can be clamped to the tool seat for inserting the vertical state tool 6, and the clamping block 46 can also be released from the tool seat 5 so that the tool seat 5 can rotate with the ring chain 38. The free end of the clamping block 46 has a semicircular notch 48 matched with the horizontal roller 49. The clamping or releasing refers to the clamping or releasing of the semicircular notch 48 and the horizontal roller 49.

The inner vertical plate 53 can also have two through holes, such as first through hole 51, for the screws to pass through and screw the inner vertical plate 53 to the horizontal plate threaded hole 52 of the horizontal plate 58. The top of the outer vertical plate 59 is lower than or equal to the top surface of the horizontal plate 58, and a horizontal roller 49 is installed in the middle of the width of the upper part of the outer vertical plate 59, such as a roller seat 68 with a horizontal roller 49 rotatingly matched is screwed on the outer vertical plate 59. The lower part of the outer vertical plate 59 has two vertical rollers 69 rotatingly matched with roller shafts and axial gland for rolling on the top surface of the rectangular top plate 35, and the lower part here can also be understood as the bottom part. The chain body 56 can also be understood as a chain body segment or a chain body section.
