Description

  The present invention relates to a product sorting and integrating system for a sheet metal processing machine.

  Conventionally, in order to stack products in a sheet metal processing machine, the number of stacking shelves is divided into a material shelf and a product shelf.

  As a method of stacking on a product shelf, there are stacking by parts and nesting stacking in which the plates are stacked.

  When taking out products, at the time of interruption work or setup before scheduled processing, the product shelves processed before that are called out and manually taken out of the shelves to be distributed and accumulated by the next process, or trading Sorted by company order.

Moreover, in a normal sorting system, there is also a system in which containers are arranged in the middle of transportation and dropped or accumulated. Generally, it accumulates in a nesting form.

  FIG. 12 is a schematic block diagram of a product sorting and accumulating system 100 including the product sorting and accumulating apparatus 101 configured as described above.

  FIG. 13 is a flowchart showing an example of the operation of the product sorting and accumulating system 100. This flowchart is divided into the conveying device 40, the processing machine main body 20, and the tray changer unit 150.

  Next, the operation of the product sorting and accumulating system 100 will be described with reference to the flowchart shown in FIG.

  When the schedule is START, the transfer device 40 takes a piece of material from the material shelf 30 (step S11), then loads the material (step S12), and then moves to a product take-out position and waits (step). S13).

  When the loading of the material is completed, the processing machine body 20 performs hole processing (step S21), and then cuts the product (step S22).

  On the other hand, when the schedule is START, the tray changer unit 150 sets the tray 110 of the wagon 130 used in the schedule to the support device 120 as much as necessary (step S31). Next, when the loading of the material is completed, the opening / closing table 121 is opened (step S32).

  When the cutting of the product is completed, the transport device 40 carries out the product (step S14) and accumulates it on the tray 110 (step S15).

  When the stacking on the tray 110 is completed (YES in step S16), the tray changer unit 150 stores the tray 110 in the wagon 130 (step S33). If the next tray is necessary (YES in step S34), the tray 110 is removed from the wagon 130 and set in the support device 120 (step S35).

  On the other hand, even if the stacking on the tray 110 is not completed (NO in step S16), if the processing is completed (YES in step S16), the transport device 40 carries out the skeleton (step S18).

  When the skeleton is unloaded, the tray changer unit 150 closes the opening / closing table 121 (step S36). When the schedule is completed (step S19), all the trays 110 of the support device 120 are returned to the wagon 130 (step S37).

  FIG. 14 is an explanatory diagram showing the wagon sorting by destination, and FIG. 15 is an explanatory diagram showing the wagon sorting by order.

  In this way, no matter how the processing program is nested, wagons are sorted by destination (or by order), and each tray in that wagon is further classified by order (or by destination). It can be stored.

  Hereinafter, various conveniences and usefulness of the product sorting and accumulating system 100 including the product sorting and accumulating apparatus 101 will be described in detail.

  That is, the product sorting and accumulating system 100 arranges several support devices 120 for the tray 110 for sorting and accumulating products between the processing machine body 20 and the conveying device 40. The support device 120 can replace the tray 110 without stopping the processing machine body 20 according to the purpose and means by calculating the empty tray 110 at any time.

  The tray 110 is stored in a wagon 130 (cart) that accommodates a large number of trays 110 using a space, and the number of wagons 130 that can be operated at the same time is arbitrarily selected according to a user's request. Can do.

  The conveyance device 40 that takes out the product and the support device 120 for the tray 110 that accumulates the product are installed between the material shelf 30 and the processing machine body 20 and increase the tact efficiency of the conveyance device 40 that reciprocates many times. It becomes the close composition which is possible. Further, the traveling path 151 of the tray changer unit 150 for moving back and forth between the support device 120 for accumulating products and the wagon 130 is disposed perpendicular to the transport direction of the transport device 40, so that the user can operate the wagon at the same time. The number of 130 can be increased.

  The wagon 130 and sorting control have the following functions.

(1) There are the following types of methods for loading products on the tray 110, which can be selected by the operator. That is, integration by parts, nesting integration, and integration by order.

(2) There are the following types of loading modes, which can be selected by the operator. In other words, single-sheet loading = high quality scratch-free mode, multiple-sheet loading = stacking high efficiency mode.

(3) Product attributes can be displayed in different colors on the wagon 130 or wagon station 140. That is, (a) lighting identification of the wagon containing the product that the worker is looking for, (b) lighting identification of the wagon that is no longer used in the schedule being executed (display for quickly carrying to the next process), (c ) Lights that can identify the closeness of the delivery date of the product in the wagon (EX. Lamp color coding).

(4) The number of shelves for the wagon 130 can be changed depending on the molding height and the number of stacked sheets. For example, when loading a 15 mm molded product, one step is skipped and the tray is stored.

  In the product sorting and accumulating system 100, a plurality of support devices 120 for the tray 110 are installed in the vicinity of the processing machine main body 20; the tray 110 of the support device 120 can be transferred and exchanged in a direction intersecting (orthogonal) with the product removal direction. Having a tray changer unit 150; a large number of trays 110 can be stored in a space-based wagon 130; a tray 110 and a wagon 130 form a tiered warehouse space; and determining that the wagon 130 is not used during a schedule Own control device; be able to display a wagon 130 containing a specific product; be able to select multiple products / tray, one product / tray in a stacking method; The decimation of the number of stages can be changed by software calculation or manually; In that it is selected and wagons 130 a plurality of selection of the tray 110; due is effective as follows.

  That is, continuous product removal can be advantageously handled in a tactile manner. In addition, the wagon 130 can have an extended layout. In addition, a space for placing a variety of products can be covered with the space. In addition, the operator can be informed and the wagon 130 can be pulled out, and the next process can proceed quickly. Further, it is possible to quickly find the wagon 130 storing the product that the worker is looking for. In addition, the user can easily perform an integration method with improved product storage efficiency and integration without damage. In addition, the product can be efficiently stored according to the processing height of the product. In addition, various combinations of next process / order / delivery date can be operated.

  Furthermore, the product sorting and accumulating system 100 is a space for sorting and accumulating from the era of mass production to the era of high-mix low-volume production. The system can be effectively constructed by performing the layout considering the arrangement and the buffer hierarchically so as to meet the machining tact of the processing machine as efficiently as possible.

  Further, the sorting destination can be provided with a wagon 130 that makes the most of the space, and has a layout that can be operated at the same time.

  Although partially overlapping with the above description, the features of the present invention will be described below in comparison with the conventional one.

  Conventionally, a part of the shelves in the loading / unloading (L-UL) apparatus is used as a stacking shelves for products, and the taken out products are loaded by nesting or parts. However, after the scheduled operation was completed, it was necessary to manually sort again from the shelf to the next process destination. Consider a system for automating this sorting and collection.

  When taking out from the processing machine, if an automatic sorting and accumulating device is attached behind the previous processing machine and the L-UL system, the moving distance of the shaft is increased during the processing, so that the shaft movement distance becomes longer. Cycle time is not in time for the machining time.

  Since L-UL is mainly used at the time of carrying in materials and taking out the remaining materials, it often moves only once in one machining program. Therefore, if it is the operation | work which takes out a processed product frequently, it is necessary to arrange | position a sorting apparatus between a processing machine and L-UL, and to shorten a pick-up tact (support apparatus 120 of FIG. 1).

  However, there is also a method of using the accumulation on the pallet mainly using the wagon accumulation. For example, larger than the size of the wagon.

  The main points when laying out the sorting and accumulating device between the processing machine and the L-UL are as follows.

  1. It is important to keep the distance between these parts unchanged according to the number of customer wagon requests and to keep the total system length as short as possible. There will also be a problem that the number of wagons cannot be increased arbitrarily by simple retrofitting. For this purpose, the track of the tray replacement device is provided perpendicular to the material transport path between the processing machine and the L-UL (tray changer unit 150 in FIG. 1).

  2. Similarly, if the wagon is placed in parallel between the processing machine and the L-UL, the system length (L-UL + the length in the direction of the processing machine) will vary depending on the number of wagons.

  6). Multiple rows of trays are possible. The trays in this row can be replaced by the support devices 120c and 120d in the same manner as the tray replacement operation at the position of the wagon 130 (the wagon station 140 in FIG. 1).

  7. The supporting devices 120c and 120d are equipped with cylinders that raise and lower the tray. After changing the tray on the lower side (C in FIG. 14), 120c and 120d are raised to the regular pass line of the support device 120 so that the changer body 160 can be replaced even when the tray is set on the support devices 120a and 120b. (A in FIG. 14).

  In the case of every four sheets, the operation is to replace one tray at a time, and the other three sheets that have not been replaced do not interfere with the operation of the changer body 160 and can be stacked at any time.

  8). The wagon station 140 is provided with an indicator lamp 141 for informing the product delivery date and the delivery time, so that the operator can be informed of the contents of the setup without having to take out the product stored in the wagon. is doing.
