Field of the Invention The present invention relates to a tape cutting / sorting system which cuts a raw material tape such as a magnetic tape into a product width, winds the product around a hub, and sorts the product by grade. About. 2. Description of the Related Art In general, a tape such as a magnetic tape is manufactured intermediately as a large one (hereinafter, referred to as a raw material) corresponding to a plurality of final products, and then cut into a predetermined width. Although it is finally manufactured, it is necessary to classify the finished product according to its characteristics and the like. For this purpose, a tape cutting / sorting system is installed in a magnetic tape manufacturing factory or the like. Conventionally, this kind of cutting and sorting system includes a slitter (tape cutting device) that cuts a raw material of a magnetic tape into a predetermined width and winds it around a hub, and a magnetic tape (hereinafter, referred to as a tape cutting device) wound around the hub by the slitter. An automatic machine such as a robot that temporarily stores all of the hub-wound magnetic tape in the temporary storage trolley is provided, and the operator inspects the grade of the hub-wound magnetic tape stored in the temporary storage trolley by the automatic machine. After making the determination, the worker again performs the work of re-transferring to the bogie based on the grade based on the result of this determination. [0004] For this reason, wasteful work of transshipment to a temporary storage cart has occurred, and the lead time until the completion of sorting has been long. In addition, in-process inventory is generated due to this, and there is a problem that it is necessary to secure the space for the temporary storage cart, and since the sorting process is performed by humans, sorting errors due to human errors also occur, There was a problem that the target cost also became high. SUMMARY OF THE INVENTION It is an object of the present invention to provide a tape cutting / sorting system which can automatically sort a hub wound tape completed by a slitter in a so-called in-line manner without temporarily placing the tape. [0006] To achieve the above object, according to solve the problems], cutting sorting system according to the present invention, a slitter winding hub by cutting the raw tape to the width of the product, prior to <br / Takes in information necessary to judge the grade of the tape between the time when the raw material of the recording tape is put into the slitter and the time when the cutting and winding processing is completed, and at the end of the cutting and winding processing of the slitter, Is compared with a reference value for determination, determines the grade of the tape wound around the hub by this slitter, grade determining means for outputting a grade instruction signal, and receives the tape wound around the hub by the slitter And sorting means for storing the tape in a sorting position corresponding to the grade together with the hub based on the grade determination signal. And butterflies. In the present invention, the slitter cuts the raw material of the tape into the width of the product and winds it around the hub, and the grade judging means performs cutting and winding after the raw material of the tape is put into the slitter. Until the processing is completed, take in the information necessary to determine the grade of the tape, compare it with a reference value for determining these information at the end of the cutting and winding processing of the slitter, and send it to the hub. The grade of the wound tape is determined, and a grade instruction signal is output. On the other hand, the sorting means receives the tape wound around the hub by the slitter, and stores the tape together with the hub at a sorting position corresponding to the grade based on the grade determination signal. Therefore, the tape completed by the slitter can be automatically sorted in a so-called in-line manner without temporarily placing the tape. [0008] EXAMPLES The following configuration of the embodiment will be described with reference to an embodiment of the present invention with reference to the drawings. As shown in FIG. 1, the tape cutting and sorting system according to the present embodiment includes a slitter 10 that cuts a raw material of a magnetic tape into a product width and winds it around a hub, and a hub-wound magnetic tape 1 completed by the slitter 10. Grade determining means 20 for determining the grade and outputting a grade instruction signal, and receiving the hub-wound magnetic tape 1 as it is from the slitter 10 via the transport device 30 and based on the grade determining signal output from the grade determining means 20 Sorting means 40 for storing the hub-wound magnetic tape 1 together with the hub at a sorting position corresponding to the grade. The slitter 10 includes an unwinding section (not shown) for feeding out a raw magnetic tape, and a knife section for continuously cutting the magnetic tape fed from the unwinding section and traveling at a predetermined position in the width direction. (Not shown), and a winding unit 11 for winding the magnetic tape unwound from the unwinding unit and cut by the knife unit. Finally, a plurality of hub-wound magnetic tapes are wound around the winding shaft 12 at one time. 1 is completed. The grade judging means 20 is constituted by a microcomputer, for example, and has the following functions. That is, between the time when the raw material of the magnetic tape is supplied to the slitter 10 and the time when the cutting and winding process is completed, information necessary for determining the grade of the magnetic tape is provided by, for example, a sensor provided on the slitter 10 or the like. , Pre-process (raw material production process)
The information is automatically taken in from the equipment or the like, and when the cutting and winding processing of the slitter 10 is completed, the information is compared with a judgment master (reference value for judgment) registered in an internal memory or the like, and the hub winding magnetic field is automatically set. Grade determination is performed for each turn of the tape 1. The hub winding magnetic tape 1 has a function of outputting a grade instruction signal indicating the determined grade to the robot controller 42 described later at the same time as being conveyed to the sorting means 40. The transport device 30 includes a transport device 31 capable of holding a plurality of hub-wound magnetic tapes 1 by inserting the hub-wrapped magnetic tapes 1 through the shaft portions on both sides;
A moving mechanism (not shown) for moving the carrier 31 from the delivery position to the slitter 10 to a delivery position to the sorting means 40, and a reversing mechanism (not shown) for inverting the carrier 31 by 180 degrees at each delivery position. Prepare. In each transfer position, for example, the hub-wound magnetic tape 1 is pushed by a pusher mechanism (illustrated in the drawing) in a state where the tip of the shaft of the carrier 31 abuts on the shaft (the winding shaft 12 of the slitter 10 or the like) at the delivery position. The hub-wound magnetic tape 1 is delivered by sliding in the axial direction according to (omitted). In this case, the sorting means 40 has an articulated robot main body 41 and a robot controller 42 of, for example, a teaching playback control system, and has a shaft portion of a jig 43 attached to the end of the arm of the robot main body 41. The hub-wound magnetic tape 1 is stored in one of the carts 51, 52 and 53 arranged at each sorting position. That is, the robot controller 42 pre-sets three types of operation programs of the robot main body 41 for transferring the hub-wound magnetic tape 1 received from the transfer device 30 to each of the carts 51, 52, 53 in an internal memory. Judgment means 2
It has a function of selecting and executing one of the operation programs according to a grade instruction signal of 0. In this case, based on the storage position parameters (parameters defining which sorting positions are to be stored) registered in advance in the robot controller 42, if the grade is “advanced”, the cart 51 If the grade is "intermediate", a program to be stored in the trolley 52 is selected, and if the grade is "lower", a program to be stored in the trolley 53 is selected. It has become. Next, the operation of the above-described magnetic tape cutting and sorting system will be described. When the raw material of the magnetic tape is set on the slitter 10 and the operation of the system is started, the raw material is cut to the width of the product by the slitter 10 and wound around the hub. Complete multiple. Then, these hub-wound magnetic tapes 1 are slitters 1
The transfer device 30 is transferred to the transfer position of the robot body 41 of the sorting means 40 by the transfer device 30 and transferred to the transfer position of the robot body 41 of the sorting device 40. It is passed to 43. When the carrier 31 receives one set of the hub-wound magnetic tape 1 on one shaft portion, it reverses and then transfers one set of the hub-wound magnetic tape 1 completed by the slitter 10 to the other side. The two sets of hub-wound magnetic tapes 1 are transferred to the shaft portion, and the two sets of hub-wound magnetic tapes 1 are simultaneously transferred to the robot main body 41. The delivery of the hub-wound magnetic tape 1 at each delivery position is performed by, for example, the pusher mechanism that presses the hub-wound magnetic tape 1 as described above. It is necessary to carry out each turn individually for each turn. On the other hand, the grade determining means 20 and the robot controller 42 perform the processing of steps S1 to S5 shown in FIG. That is, first, the grade determining means 20
Information required to determine the grade of the magnetic tape between the time when the raw material is put into the slitter 10 and the time when the cutting and winding process is completed (in FIG. 2, the pre-process management information, the in-line characteristic inspection information and the in-line characteristic inspection information). (Appearance inspection information) is automatically taken in from, for example, a sensor provided in the slitter 10, equipment in a previous process (raw material manufacturing process), and the like (Step S).
1) At the end of the cutting and winding process of the slitter 10, the above information is compared with a judgment master registered in an internal memory or the like, and a grade judgment is automatically made for each turn of the hub-wound magnetic tape 1 (step). S2). At the same time as the hub-wound magnetic tape 1 is transferred to the robot main body 41, a grade instruction signal indicating the determined grade is output to the robot controller 42 (step S3). When the grade instruction signal is output, the robot controller 42 executes a corresponding program (step S4). That is, for example, when the grade instruction signal indicates “advanced”, an operation program to be stored in the cart 51 is selected and executed based on the storage position parameter. Then, the robot body 4
1 stores the hub-wound magnetic tape 1 received under the control of the robot controller 42 in the carriage 51 (step S5). The hub-wound magnetic tape 1 completed by the slitter 10 is successively transferred to the robot main body 41 as it is, and each time a grade instruction signal is output from the grade determining means 20 and the sorting processing by the sorting means 40 is performed. At this time, the signals indicating the operating states of the slitter 10 and the transport device 30 are sequentially input to the grade determining means 20 so that the hub-wound magnetic tape 1 transferred to the robot body 41 is Correspondence with the corresponding grade determination data is made. As described above, according to the system described above, the hub-wound magnetic tape 1 completed by the slitter 10 is transferred to the sorting means 40 as it is, and is automatically determined by the grade determining means 20 and outputted. , The hub-wound magnetic tape 1 is stored in a truck (sorting position) corresponding to the grade. Therefore, the hub-wound magnetic tape 1 completed by the slitter 10
Can be automatically sorted in a so-called in-line manner without temporary placement, and the following various excellent effects (a) to (d) can be obtained. (A) The lead time and the number of steps required to complete the sorting of the magnetic tape are reduced. (B) There is no in-process due to temporary placement, and no space is required for it. (C) Sorting errors due to human errors are eliminated. (D) Since all processes from cutting to sorting are performed automatically, human production costs can be reduced. Modifications The present invention is not limited to the above-described embodiment, but may have various aspects. For example, the transport device 30 may be omitted, and the hub-wound magnetic tape 1 may be directly transferred from the winding shaft 12 of the slitter 10 to the sorting unit 40. However, in this case, unless all the hub-wound magnetic tapes 1 are stored in a predetermined carriage by the operation of the robot main body 41, the cutting and winding operation of the next raw material by the slitter 10 cannot be started. In this respect, in the above embodiment, the robot main body 4 has a structure in which a set of the hub-wound magnetic tape 1 is temporarily delivered to the carrier 31 of the carrier device 30.
The cutting and winding operation of the next raw material can be started without waiting for the sorting operation of No. 1 and by sorting the completed hub-wound magnetic tape 1 in the middle of the cutting and winding operation of the next raw material, It has unique advantages that it can increase production efficiency and work efficiency. According to the present invention, the tape completed by the slitter can be automatically sorted in a so-called in-line manner without temporarily placing the tape, so that the lead time can be reduced, the number of steps can be reduced, the number of processes in progress can be reduced, and Various effects such as avoiding sorting errors due to errors and reducing human production costs can be achieved.
