Description

  The present invention relates to a card-like sheet delivery method for delivering a card-like sheet to a suction table that sucks and holds the card-like sheet by vacuum suction from a suction head that sucks and holds the card-like sheet, and a card used therefor The present invention relates to a sheet delivery device.

  A multilayer ceramic capacitor, which is one of typical multilayer ceramic electronic components, includes, for example, a plurality of internal electrodes 52a and 52b stacked in a ceramic element 51 via a ceramic layer 53, as shown in FIG. The internal electrodes 52a and 52b facing each other through the ceramic layer 53 are alternately drawn out to the opposite end faces 54a and 54b of the ceramic element 51 and connected to the external electrodes 55a and 55b formed on the end faces. have.

  A multilayer ceramic capacitor having such a structure is usually formed by laminating a ceramic green sheet on which a conductive paste is printed and applied to form an internal electrode pattern on the surface, and internal electrodes are formed on both upper and lower surfaces. A process of forming external electrodes on both ends of the fired laminate (ceramic element) after laminating and pressing non-ceramic green sheets (dummy sheets), dividing into individual elements (cutting) and firing. It is manufactured after.

  By the way, as a ceramic green sheet laminated | stacked as mentioned above, the card-shaped ceramic green sheet (card-like sheet | seat) normally obtained by cut | disconnecting the elongate sheet | seat in which the internal electrode pattern was printed to a predetermined dimension. ) Is used.

As a method for conveying (delivering) such a card-like print sheet, for example, a method shown in FIG. 9 is known (see Patent Document 1).
In this method, as shown in FIG. 9, a suction table (holding) in which a green sheet (card-like sheet) 65 stacked on a supply table 62 using a sheet conveying device 61 is stopped at a predetermined transfer position. Table) 63. Specifically, the sheet conveyance device 61 is moved above the supply table 62 and the suction head 64 is lowered to a position where the suction surface of the suction head 64 is in contact with the upper surface of the green sheet 65 or in the vicinity thereof. Then, a negative pressure is applied to the suction surface to hold the green sheet 65 on the suction head 64.
Next, after the suction head 64 is raised, the sheet conveying device 61 is moved to above the suction table (holding table) 63, and then the suction head 64 is lowered to release the negative pressure action on the suction surface. The green sheet 65 is transferred onto the suction table (holding table) 63.
The suction table (holding table) 63 is configured to reliably hold the green sheet 65 by applying a negative pressure to the suction surface (vacuum suction).

  In the method disclosed in Patent Document 1, a card-like sheet (green sheet) 65 is delivered from a suction head 64 having a suction holding function to a suction table 63 having a suction holding function. The timing for turning on the suction of the suction table 63 and the timing for turning off the suction of the suction head 64 when delivering the card-like sheet 65 to the suction table 63 are not necessarily clearly described. However, with respect to the timing at which the suction of the suction table 63 is turned on and the timing at which the suction of the suction head 64 is turned off, the suction of the suction head 64 is turned off so that the delivery of the card-like sheet 65 is reliably completed. In general, the suction of the suction table 63 is generally turned on.

  By the way, when a card-like sheet having an undried internal electrode pattern formed in the central area is sucked and conveyed by a suction head, for example, in order to prevent the suction head from contacting the internal electrode pattern in the central area, for example, FIG. As shown in FIG. 10, it is necessary to hold the card-like sheet 65 using a suction head 64 having a recess 71 formed in the center.

However, when the card-like sheet 65 is sucked and held using the suction head 64 in which the concave portion 71 is formed in the center, the center part of the card-like sheet 65 is not sucked and held by the suction head 64, as shown in FIG. Deflection occurs at the center of the card-like sheet 65. In this state, as shown in FIGS. 11 and 12, when the card-like sheet 65 is delivered from the suction head 64 to the suction table 63, it is delivered to the suction table 63 while the card-like sheet 65 is bent. Since the card-like sheets 65 are held by suction, wrinkles 66 are generated in the card-like sheets 65, which causes a problem such as stacking deviation when the card-like sheets 65 are stacked.

The card-like sheet delivery device of the present invention (Claim 5),
(a) The card-shaped sheet is configured such that the head central area corresponding to the central area of the card-like sheet on which an undried electrode pattern is printed in an area other than the peripheral area on the sheet surface does not contact the card-like sheet. The head peripheral area corresponding to the peripheral area of the head is configured to contact the card-like sheet as a suction surface, and the suction means for holding the card-like sheet by vacuum suction and gas are blown into the head peripheral area.

In addition, the suction head is configured to perform suction OFF and blow ON while there is a gap between the card-like sheet and the suction table .

The card-like sheet delivery device according to claim 6 is characterized in that the central region of the head has a concave shape so as not to contact the central region of the card-like sheet.

According to a seventh aspect of the present invention, there is provided the card-like sheet delivery device, wherein a contact portion of the suction head with the card-like sheet is formed using an elastic material.

The card sheet delivery apparatus according to claim 8 is characterized in that a blowing means for blowing gas is also provided in a central region of the suction head.

The card-like sheet delivery method of the present invention (Claim 1) is a method for delivering a card-like sheet on which an undried electrode pattern is printed in an area other than the peripheral area on the sheet surface, The area is configured as an adsorption surface, and a suction function for holding the card-like sheet by vacuum-sucking the peripheral area of the card-like sheet from the adsorption surface, and gas is blown from the adsorption surface to the peripheral area of the card-like sheet Using a suction head equipped with a blow function to release the card-like sheet, vacuum suction is performed on the peripheral area of the card-like sheet to hold the card-like sheet, and suction is performed when the card-like sheet is transferred to the suction table. a suction OFF of the head, the timing of the blow oN, thereby to become earlier than the timing of the suction oN of the suction table, the suction head Located above the suction table and are in a state in which there is a gap between the card-like sheet and the suction table, to perform the transfer of the card-like sheet by performing a suction OFF and blow ON suction head. As a result, it is possible to remove the deflection generated in the central area of the card-like sheet (the area where the deflection is not performed and the deflection is generated), and then suction and hold the card-like sheet, thereby generating wrinkles on the card-like sheet. Therefore, the card-like sheet can be reliably transferred from the suction head to the suction table.

  That is, when the card-like sheet is transferred to the suction table, the vacuum suction of the suction head is stopped and the blow is started before the vacuum suction of the suction table is started, and the card-like sheet is released from the suction head. Thus, it is possible to secure a time for removing the deflection of the card-like sheet, and thereafter, by starting the vacuum suction of the suction table, the card-like sheet is reliably generated without generating wrinkles. The sheet can be transferred to the suction table.

  In addition, when the card-like sheet is a card-like print sheet in which an undried electrode pattern is printed in an area other than the peripheral area on the sheet surface, when the center area of the head is an adsorption surface, The dry internal electrode pattern adheres and the internal electrode pattern is damaged. However, like the card-like sheet delivery method of the present invention, the peripheral area is configured to be an adsorption surface, and the card is formed from the adsorption surface. By holding a suction head having a suction function for holding only the peripheral area of the card-like sheet by vacuum suction of the peripheral area of the card-like sheet, the card-like sheet can be sucked and held without contacting the internal electrode pattern Is possible. Therefore, it is possible to reliably perform delivery from the suction head to the suction table without damaging the internal electrode pattern and without causing wrinkles in the card-like sheet.

  When the card-like sheet is released by blowing gas from the suction head as in the card-like sheet delivery method of claim 2, the card is also blown from the central area of the suction head. It is possible to blow gas almost over the sheet-like sheet, eliminating deflection and deflection bias, and more reliably delivering from the suction head to the suction table without generating wrinkles on the card-like sheet. It becomes possible to do.

  In the card-like sheet delivery method of the present invention, when the card-like sheet is delivered to the suction table, the suction head suction OFF and the blow ON timing are earlier than the suction ON timing of the suction table. As a result, the timing at which the card-like sheet becomes free occurs, and the deflection is removed, while the positional accuracy is somewhat lowered, but the subsequent process is a drying process of the card-like sheet. Some positional deviation is allowed. Therefore, the present invention provides a drying step of drying the electrode pattern printed on the card-like sheet, wherein the post-step of the card-like sheet delivery step does not require so high accuracy as the delivery positional accuracy. This is particularly significant as a card-like sheet delivery method and apparatus used in such a case.

  Further, when the rising timing from the bottom dead center of the suction head is after the timing of suction ON from the suction hole of the suction table, as in the card sheet delivery method of claim 4, the suction head When rising, it is possible to prevent the card-like sheet from being accompanied by the suction head and to reliably hold the card-like sheet on the suction table.

Further, the card-like sheet delivery device according to the present invention (Claim 5) is: (a) the head central region in which an undried electrode pattern is printed in an area other than the peripheral area on the sheet surface is in contact with the card-like sheet. The head peripheral area corresponding to the peripheral area of the card-like sheet is configured to contact the card-like sheet as an adsorption surface, and suction means and gas for holding the card-like sheet are provided in the head peripheral area. A suction head having a structure in which blow means for releasing the card-like sheet by blowing is disposed; and (b) a suction table having suction means for holding the card-like sheet by vacuum suction; and The suction head suction OFF and blow ON timing are made earlier than the suction ON timing of the suction table , and the suction head The suction head is turned off and blown on in a state where there is a gap between the card-like sheet and the suction table. After removing the deflection generated in the central area of the sheet, it becomes possible to suck and hold it on the suction table, and reliably transfer the card-like sheet from the suction head to the suction table without generating wrinkles on the card-like sheet. Is possible.

  In addition, when the card-like sheet is a card-like print sheet in which an undried electrode pattern is printed in an area other than the peripheral area on the sheet surface, when the center area of the head is an adsorption surface, The dry internal electrode pattern adheres and the internal electrode pattern is damaged. However, like the card-like sheet delivery device of the present invention, the peripheral area is configured to be an adsorption surface, and the card is formed from the adsorption surface. By holding a suction head having a suction function for holding only the peripheral area of the card-like sheet by vacuum suction of the peripheral area of the card-like sheet, the card-like sheet can be sucked and held without contacting the internal electrode pattern Is possible. Therefore, it is possible to reliably perform delivery from the suction head to the suction table without damaging the internal electrode pattern and without causing wrinkles in the card-like sheet.

Further, as in the card-like sheet delivery device according to claim 6 , the head central region has a concavely recessed structure, so that the head central region is not reliably brought into contact with the central region of the card-like sheet. It becomes possible to make the present invention more effective.

Further, when the suction head moves to the bottom dead center by forming the contact portion of the suction head with the card-like sheet using an elastic material as in the card-like sheet delivery device according to claim 7. Even if the card-like sheet is sandwiched between the suction head and the suction table, the card-like sheet is prevented from being damaged, and the present invention can be further effectively realized.
In addition, as an elastic material which comprises a contact part, it is possible to use various materials, such as resin and rubber | gum.

Further, when the blow means for blowing the gas is also provided in the central region of the suction head as in the card-like sheet delivery device according to claim 8 , the gas is blown almost entirely on the card-like sheet. Therefore, it is possible to eliminate the deflection and the bias of the deflection, and more reliably transfer from the suction head to the suction table without generating wrinkles on the card-like sheet.

  The features of the present invention will be described in more detail below with reference to examples of the present invention.

  FIG. 1 is a cross-sectional view schematically showing a configuration of a card-like sheet delivery device according to one embodiment (Example 1) of the present invention. FIG. 2 is a diagram showing the configuration of the suction surface of the suction head constituting the card-like sheet delivery device of this embodiment, and FIG. 3 is a diagram showing the configuration of the upper surface of the suction table.

  The card-like sheet delivery device according to the first embodiment prints an internal electrode pattern on a long sheet, and sucks and holds the card-like sheet formed by cutting to a predetermined size with a suction head. It is a delivery apparatus of the card-like sheet from a suction head to a suction table used for delivery to the suction table for conveying to the drying process.

  As shown in FIGS. 1 to 3, the card-like sheet delivery device sucks, holds, and conveys the card-like sheet 1 having the undried internal electrode pattern 2 disposed on the surface of the central region 1 b. 10 and a suction table 20 on which the card-like sheet 1 sucked and held by the suction head 10 is delivered.

  In the suction head 10, the peripheral area (head peripheral area) 11 is a suction surface that contacts the peripheral area 1 a of the card-like sheet 1 where the internal electrode pattern 2 is not provided, and the suction surface (head peripheral area). 11, a plurality of suctions for sucking and holding the card-like sheet 1 by vacuum suction and blowing the gas so that the card-like sheet 1 held by suction can be reliably released from the suction head 10. A blow hole 12 is arranged, and the suction / blow hole 12 is configured to function as a card sheet suction means and a blow means.

A recess 14 is formed in a central area (head central area) 13 on the lower surface side of the suction head 10, and is formed in the central area 1 b of the card-like sheet 1 even when the suction head 10 is lowered. It is comprised so that it may not contact with the internal electrode pattern 2 of an undried state.
The head central region 13 is provided with a plurality of blow holes (blow means) 15 for blowing gas to release the card-like sheet 1.

  The suction table 20 to which the card-like sheet 1 sucked and held by the suction head 10 is delivered is provided with a plurality of suction holes (suction means) 21 for sucking and holding the card-like sheet 1 by vacuum suction. ing.

  In the card-like sheet delivery apparatus according to the first embodiment, the suction OFF and blow ON timings of the suction head 10 are configured to be earlier than the suction ON timing of the suction table 20.

  Further, in the card-like sheet delivery device according to the first embodiment, after the suction head 10 is lowered to the bottom dead center, the rising timing is after the timing when the suction of the suction table 20 is turned on. ing.

  Next, a method for delivering a card-like sheet using the card-like sheet delivery apparatus configured as described above will be described.

  First, the card-like sheet 1 is sucked and held by the suction head 10. For example, when a card-like sheet is held by a suction head 10 from a supply table (not shown) having a suction function and a blow function, first, the suction head 10 or the supply table is moved to the receiving position of the card-like sheet 1. After that, the suction head is lowered (or the supply table is raised), and when the suction head 10 reaches the bottom dead center, the suction of the suction head 10 is turned ON, and then the suction of the supply table is turned OFF and simultaneously supplied. The table blow is turned on and the card-like sheet 1 is transferred from the supply table to the suction head 10.

Next, the suction head 10 is raised and moved to a region where the card-like sheet 1 is transferred to the suction table 20. It should be noted that various methods using a combination of a motor and a ball screw, an air cylinder, or the like can be applied to transport the suction head 10.
Then, the suction head 10 is lowered, and the card-like sheet 1 is transferred to the suction table 20.

Hereinafter, the delivery timing of the card-like sheet 1 will be described with reference to FIGS.
4 to 6 are diagrams illustrating each process of delivering the card-like sheet 1, and FIG. 7 is a timing chart when delivering the card-like sheet 1 from the suction head 10 to the suction table 20. .

(1) First, as shown in FIG. 4, the suction head 10 that sucks and holds the card-like sheet 1 is lowered toward the suction table 20. At this time, since the card-like sheet 1 is sucked and held by using the suction head 10 in which the concave portion 14 is formed in the central area, as shown in FIG. Has occurred.
In the card-like sheet delivery device of the present invention, the suction head 10 can be configured to come into contact with the suction table 20 when the suction head 10 descends and reaches the bottom dead center. The suction head 10 may be configured not to contact the suction table 20.
That is, in order not to damage the card-like sheet 1, it is desirable that the suction head 10 does not contact the suction table 20, but the contact portion of the suction head 20 with the card-like sheet 1 is elastic. In the case of being constituted by a body, since the card-like sheet can be prevented from being damaged, it is possible to constitute the suction head 10 in contact with the suction table 20.

(2) Then, immediately before the suction head 10 reaches the bottom dead center, as shown in FIG. 5, the suction of the suction head 10 holding the card-like sheet 1 is turned off, and the suction / blow hole 12 and blow By turning on the blow from the hole 15, the card-like sheet 1 is peeled off from the suction head 10 and released.
Thus, since the card-like sheet 1 is peeled and released from the suction head 10 before the suction head 10 reaches the bottom dead center, the central area of the lower surface is sucked and held by the concave suction head 10. The card-like sheet 1 in a state where the region 1b is bent is in a free state released from stress for a short time, but the deflection is removed.
In the first embodiment, as described above, when the suction of the suction head 10 is turned off and the blow is turned on, the suction / blow hole 12 formed in the suction surface 11 of the suction head 10 and the center of the head Since blowing is simultaneously performed from the blow holes 15 disposed in the region 13, it becomes possible to blow gas over almost the entire card-like sheet 1, and the bent card-like sheet 1 can be more reliably extended. It becomes possible to make it flat.
In addition, the timing adjustment of the suction OFF and the blow ON of the suction head 10 is performed, for example, the position adjustment of the sensor for confirming the top and bottom dead center of the suction head 10, the timer setting from when the suction head 10 is lowered, etc. This method can be used.

(3) After the suction head 10 reaches the bottom dead center, as shown in FIG. 6, the suction of the suction table 20 is turned on, and the card-like sheet 1 has the entire lower surface in a state where the deflection is eliminated. 20 is sucked and held in a stable state in a flat state.
On the other hand, the suction head 10 is lifted after the blow from the blow hole 15 is turned off, and is returned to a predetermined position to suck and hold the next card-like sheet from the supply table.
Thus, the delivery of the card-like sheet 1 from the suction head 10 to the suction table 20 is completed, and the card-like sheet 1 delivered to the suction table 20 is held in the suction table 20 in the next process (this implementation). In the example, it is conveyed to a drying step).

  In the case of the configuration of the first embodiment, the blow time from the suction head 10 and the bottom dead center residence time of the suction head 10 are preferably as short as possible, but when the suction head 10 is raised, When the suction of the suction table 20 is not ON, the card-like sheet 1 may be accompanied at the same time as the suction head 10 is lifted. Therefore, it is desirable to raise the suction head 10 after the suction table 20 sucks and holds the card-like sheet 1.

  As described above, in the card-like sheet delivery device (card-like sheet delivery method) of this embodiment, the suction head that sucks and holds the card-like sheet 1 by vacuum suctioning only the peripheral area 1a of the card-like sheet 1. 10, when the card-like sheet 1 is delivered to the suction table 20, the vacuum suction OFF and blow ON timings of the suction head 10 are made earlier than the suction ON timing of the suction table 20. Before the suction head 10 reaches the bottom dead center, the card-like sheet 1 is released from the suction head 10 and the deflection of the central region 1b of the card-like sheet 1 is removed, and then the suction table 20 is sucked and held. Is possible. Accordingly, the card-like sheet 1 can be reliably delivered from the suction head 10 to the suction table 20 without generating wrinkles in the card-like sheet 1.

  In the card-like sheet delivery apparatus (card-like sheet delivery method) according to the first embodiment, when the card-like sheet 1 is delivered to the suction table 20, the suction OFF of the suction head 10 and the timing of blow-on are performed. However, since the timing at which the card-like sheet is freed is generated and the deflection is removed, the positional accuracy is somewhat lowered. Since the post-process is a drying process of the card-like sheet 1, a slight positional deviation (for example, a positional deviation of about ± 0.5 to 1.0 mm) does not become a problem. That is, the present invention is particularly significant as a card-like sheet delivery method and apparatus in a case where the internal electrode pattern is in an undried state and the positional accuracy for delivery is not so high.

  In addition, when laminating ceramic green sheets in the production process of multilayer ceramic electronic components, etc., high positional accuracy is required. However, in such a case, the drying of the internal electrode pattern is usually finished. The card-like sheet can be surely held so that the entire surface of the card-like sheet including the central region in which the internal electrode pattern is disposed is sucked and no positional deviation occurs.

  The present invention is not limited to the above-described embodiments, and is formed in a specific configuration of the suction head and the suction table, a type of card-like sheet, a specific arrangement position of the internal electrode pattern, and a central region of the suction head. Various applications and modifications can be made within the scope of the invention with respect to the shape of the recess to be made.

  As described above, according to the invention of the present application, for example, a card-like print sheet in which an inner electrode pattern in an undried state is printed in the central region is damaged without causing wrinkles. It is possible to reliably transfer from the suction head to the suction table.

  Therefore, in the present invention, for example, a card-like sheet formed by printing an internal electrode pattern on a long sheet and cutting it to a predetermined size is sucked and held by a suction head and conveyed to the drying process of the internal electrode pattern. Therefore, the present invention can be widely applied to a manufacturing process of a multilayer ceramic electronic component that includes a process of transferring to a suction table.
