Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly intended to hold each work individually for drying various works such as printed matter printed in the screen printing process, and to automate a series of screen printing processes. The present invention relates to a circulating and moving holding device for various works such as printed matter.

[0002]

2. Description of the Related Art Conventionally, in order to dry a printed matter printed in a screen printing process, a dry rack has been used in which a plurality of undulating shelves are arranged at appropriate intervals for each printed matter. ing. In order to set the printed matter on each shelf of this dry rack, each shelf located at the upper side is erected upright, and while the shelf is lowered horizontally, it is sequentially placed on the lower shelf. Shall be inserted,
These are done manually.

However, inserting a work on the lower shelf plate imposes an unreasonable posture on the operator, and in order to eliminate this, the shelf plate proposed as Japanese Utility Model Laid-Open No. 3-59904 is proposed. There is a lift type dry rack.

[0004]

However, even with this dry rack of the shelf-elevating type, it is the manual operation of the operator to insert and set the work on each of the shelf boards. However, for example, even with a fully automatic screen printing machine in which a series of processes such as alignment of a work in a screen printing machine, loading into a printing mechanism, printing, and discharging are automated, after the screen printing is completed, However, it is necessary to manually insert and set each work, which is a big obstacle in the work of fully automating.

Not only that, but the dry rack itself
Since the shelf board is made of wire frame and has an open structure that the entire area is open without being covered, the odor of printing ink, photosensitive emulsion, etc. is dissipated to the surroundings. It also made the environment poor and impaired the health of workers.

On the other hand, in a fully automatic system for automatically positioning a work in order to put the work in a predetermined printing position in a screen printing machine, for example, a set of loading the work into the positioning device in the screen printing machine is not performed. Since it is performed manually, even if automatic processing is achieved only within the screen printing machine, it is difficult to automate a series of overall operations, and there has been a demand for total automation of these operations.

Therefore, the present invention was created in view of the above existing circumstances, and it is possible to automatically insert and set a printed matter after printing is completed in association with discharge from a screen printing machine. A series of operations can be fully automated, and the drying process can be shortened.
In addition, it is not only excellent in deodorization and dustproof, but can also automatically load the work into a fully automatic screen printing machine, for example, and it is a circulating movement holding device for various works such as printed matter that is also useful for total fully automatic processing. The purpose is to provide.

The rear portion of the tray transporting vehicle 60 is opened so that the tray transporting truck 60 can be directly inserted therein. For guiding the entry, for example, angle-shaped guide rails 13 that come into contact with the left and right outer surfaces of the tray transporting truck 60 are provided. It is laid and fixed along the front-rear direction on the inner surface of the bottom of the left and right side walls (see FIG. 9). Also, in the front,
A work receiving rack 15 connected to a transfer portion of the work W discharged from the screen printing machine S and, if necessary, conveyed through the discharge device P, is continuously provided so as to project forward. When viewed from the side, the entire frame 11 has a substantially inverted T-shape (see FIG. 1). The work receiving rack 15 itself is not limited to being integrally connected to the box frame 11 as shown in the figure, but may be connected to the screen printing machine S or the discharging device P side or the box depending on the case. It may be configured as a separate member that can be connected to the frame 11.

Although not shown, the box frame 11 may be provided with an odor eliminating device for treating odors such as printing ink, photosensitive material, paint and the like filled in the box frame 11 and the outside. An opening / closing door or the like may be provided to prevent the radiation to the inside.

The circulating and conveying device 20 in the illustrated example raises the tray T, which is circulated and moved in the box frame 11, on the front side of the box frame 11 and lowers it on the rear side, while on the upper side, the front side. To the rear side, and in the lower part, a circulation path is formed to pass from the rear side to the front side. That is, as shown in FIGS. 3 to 6, the inner width of each of the left and right front inner surfaces of the box frame 11 corresponds to the width of the tray T, and the upper width of the tray T circulates in the vertical direction. The ascending / circulating mechanism 21 is formed by straddling a pair of front and rear ascending chains 22, and an angled tray shelf 25 is mounted between the front and rear ascending chains 22. Similarly, the inner surface of the rear portion of the box frame 11 is arranged. A pair of front and rear descending chains 32 that circulate in the up-down direction are laid across the left and right sides so that the inner side of the tray T faces downward correspondingly to the width of the tray T. A descending circulation mechanism 31, which is formed by mounting an angled tray shelf 35, is arranged at the bottom. Further, a slider 45 that engages with the tray T on the tray shelf 25 located at the uppermost stage of the ascending circulation mechanism 21 and moves and slides the tray T on the tray shelf 35 located at the uppermost stage of the descending circulation mechanism 31 is provided. An upper slide mechanism 34, which is formed by hanging a circulating slide chain 44 around the front and rear, is arranged, and the tray T is detached from the lowermost position of the rearward lowering circulation mechanism 31, and the lowermost position of the frontward ascending circulation mechanism 21. And a lower slide mechanism 51 for moving and sliding the tray T is arranged.

The ascending / circulating mechanism 21 and the descending / circulating mechanism 31 respectively include a drive motor 23 in which an ascending chain 22 and a descending chain 32, which circulate along the vertical direction of the inner surface of the box frame 11, are arranged on the upper side wall of the box frame 11.
Upper and lower sprockets 2 driven by the driving force of 33
4 and 34 are hung around each other, and between the left and right ascending chains 22 and between the descending chains 32 on the left and right, respectively, when these chains 22 and 32 move on the inner side of the box frame 11. The tray shelves 25 and 35 are mounted so that the width of the gap substantially corresponds to the width of the tray T. Further, the left and right ascending chains 22 and the left and right descending chains 32 are circulatively driven in synchronization via transmission means 26 and 36 including transmission gear boxes. Then, when the left and right tray shelves 25, 35 in each of the circulation mechanisms 21, 31 are intermittently raised and lowered synchronously, the left and right edges of the tray T are placed so that the tray T is placed.
While supporting itself from both sides, the ascending circulation mechanism 21 intermittently raises the tray T, and the descending circulation mechanism 31 intermittently lowers the tray T (see FIG. 4).

The upper slide mechanism 41 is symmetrical between the front and rear sprockets 43, which are driven by the driving force of the drive motor 42 arranged on the upper side wall of the box frame 11, on the left and right sides of the box frame 11 along the front-rear direction. A pair of left and right slide chains 4 arranged and circulated
4, the sliders 45 that engage with the tray T are connected to the respective slide chains 44 (see FIGS. 3 to 5). And this slide chain 44
Is smaller than the width of the tray T, and from the end of the ascending circulation mechanism 21 which is the front end position in the box frame 11 to the end of the descending circulation mechanism 31. The tray T is arranged and is conveyed from the upper position of the ascending circulation mechanism 21 to the upper position of the descending circulation mechanism 31 and passed from the former 21 to the latter 31. The slider 45 engages with the rear end edge of the tray T located at the uppermost stage of each of the ascending circulation mechanism 21 and the descending circulation mechanism 31 from the outside in the circulation path of the slide chain 44, and the front portion of the box frame 11 is engaged. The tray 21 is moved and slid so as to transfer the tray T from the former 21 on the side to the latter 31 on the rear side.

The upper slide mechanism 41 in the drawing is
Although arranged on the lower surface of the upper side wall of the box frame 11, in some cases, the slide chains 44 are symmetrically arranged on the left and right side walls of the box frame 11 to engage the left and right edges of the tray T from the side. It is also possible to move by moving.

The upper slide mechanism 41 itself is
A shaft member for supporting the sprocket 43 is formed on a base member fixed to the lower surfaces of the left and right base pipes 46 mounted along the front-rear direction on the upper side wall of the box frame 11, and the tray is provided at the uppermost position in the ascending / circulating mechanism 21. A sensor means 27 is attached to detect that T has been conveyed upward, and drive the upper slide mechanism 41 itself to move it to the descending circulation mechanism 31.

On the other hand, the lower slide mechanism 51 is of a belt drive type which is placed and conveyed on the upper surface of the lower circulation mechanism 31 so that the tray T located at the lowermost stage position is moved to the lowermost position of the ascending circulation mechanism 21. As one. That is, as shown in FIGS. 4 to 6, between the front and rear belt pulleys 53 driven by the driving force of the drive motor 52 arranged at the bottom of the box frame 11, the left and right sides in the front and rear direction in the box frame 11 are separated. The pair of left and right conveyor belts 54 are arranged symmetrically on both sides so that the distance between them is smaller than the width of the tray T, and the tray T is placed on the upper surface and circulated. Then, the left and right tray shelves 35 that circulate and swivel in the descending circulation mechanism 31 are separated from the upper surface position of each of the transport belts 54 to the left and right sides, thereby releasing the trays T that are supported and onto the transport belt 54. The left and right tray shelves 2 that circulate and swivel in the ascending circulation mechanism 21 at the mounting height position.
By the approaching of 5 from the left and right sides, the trays 5 on the conveyor belt 54 are supported to correspond to the height positions at which the tray T is lifted away from the conveyor belt 54.

The transport belt 54 itself in the lower slide mechanism 51 is slidably guided on the upper surfaces of the left and right plate-shaped belt guides 55 mounted along the front-rear direction at the bottom of the box frame 11. The downward deflection due to the weight of the tray T is prevented, and the transfer operation of the tray T from the descending circulation mechanism 31 to the ascending circulation mechanism 21 is surely performed. Further, a sensor means 37 for detecting that the tray T is lowered and conveyed to the lowermost position in the descending circulation mechanism 31 and driving the lower slide mechanism 51 itself so as to move it to the ascending circulation mechanism 21 is additionally provided. (See Figure 9).

The lower slide mechanism 51 itself is
As in the present embodiment, the tray T may not be supported by its lower surface to be transported, but may have a transport structure in which the rear end edge of the tray T is pressed and moved from the outside. If necessary, it is possible to adopt a transport slide structure of several stages divided into front and rear so that the transfer between them can be smoothly performed.

An example of the operation of the circulating and conveying device 20 in the tray rack 10 is as follows. In the ascending circulation mechanism 21, the tray T held on the tray rack 25 is intermittently raised, while in the descending circulation mechanism 31. The tray T, which is also held on the tray shelf 35, is intermittently lowered. In the upper slide mechanism 41, the ascending circulation mechanism 2
The tray T which has reached the uppermost position in 1 is moved to the ascending circulation mechanism 2
The descending circulation mechanism 3 that is empty from the tray shelf 25 of No. 1
In the lower slide mechanism 51, the tray T that has reached the lowermost position in the lower circulation mechanism 31 is moved to the tray shelf 35 of No. 1 and the tray T of the lower circulation mechanism 31 is also emptied to start rising. It is transferred to the tray shelf 25 of the mechanism 21. Therefore, when the trays T, which are held in a step-like stacked state in the front and rear portions on the tray transport carriage 60 described later, are loaded into the tray rack 10 and positioned on the tray shelves 25 and 35, respectively, The tray T is set in the tray rack 10 by the operation of the circulation transfer device 20.
Is circulated while maintaining a horizontal state.

On the other hand, as shown in FIGS. 7 to 9, the tray carrier 60 has a tray T on each of the front and rear sections divided into front and rear.
Grips that hold the trays in a stack, and hold a rectangular carriage main body 61 that is long in the front and back on a flat surface with casters attached to the bottom surface and a plurality of trays T that are placed in the front and rear portions, respectively, in a stepped shape. The tray T is lifted and positioned at the lowest position of the mechanism 65, the ascending circulation mechanism 21 and the descending circulation mechanism 31 of the circulation conveyance device 20 in the tray rack 10, and while the circulation conveyance device 20 is operating, the circulation conveyance device 20 is operated. The lift mechanism 81 is provided for moving up and down the support frame 82 that moves up and down so as to be retracted below the transport belt 54, which is the transport surface of the lower slide mechanism 51 in 20.

The trolley body 61 avoids the lower slide mechanism 51 between the front portions of the left and right support frame members 62 which are formed by disposing a pair of square pipe-shaped members between upper and lower strip-shaped plates. So that you can enter the box frame 11,
The supporting frame member 62 is connected by a holding frame 63 which is made of a substantially rectangular frame as viewed from the front and which projects upward.
The two rear parts are connected by a joint member 64 to form a substantially rectangular frame on a plane, and a moving handle 59 having a substantially rectangular shape when viewed from the front is provided at the rear part for the traveling movement of the tray carrier 60 itself. It is made up of. The outer lateral width of the support frame member 62 corresponds to the inner lateral width between the guide rails 13 at the bottom of the box frame 11, and the front and rear lengths substantially correspond to the inner lateral length of the box frame 11. A lower slide mechanism 51 is arranged between the left and right support frame members 62 when the tray carrier 60 itself enters the tray rack 10 (see FIG. 5).

The tray carrier 60 itself is the tray rack 1.
When the tray T on the trolley main body 61 is placed on the tray shelves 25 and 35 of the ascending circulation mechanism 21 and the descending circulation mechanism 31, respectively, when the tray T is set in 0, the grip mechanism 65 is
The tray T is positioned so as to correspond to and match the lever handle 75 attached to the box frame 11 for engaging and holding the tray T and releasing it. And because of these,
The tray carrier 60 itself, which is placed in the box frame 11, is firmly fixed and held at a predetermined position in the tray rack 10 by a caster on the bottom of the carriage main body 61 or an appropriate stopper (not shown). I am doing it.

As shown in FIGS. 6 to 9, the grip mechanism 65 engages with the tray T so as to prevent the collapse of the load of a large number of trays T mounted in a stepped manner on the carriage main body 61. The stacking state is maintained, and when loaded in the circulation transfer device 20 and placed on the tray shelves 25, 35, the engagement is released. That is,
As shown in the figure, the engaging portions 1 having a substantially L shape in the outwardly facing planes symmetrically provided on the front and rear edges of the tray T are engaged and held from the left and right outer sides to form a stack. It holds the entire tray T group. Therefore, in the grip mechanism 65 itself, the slide plate 67 is slidably arranged in the left-right direction on the slide guide base 66 fixed on the substantially central surfaces of the left and right side edges of the carriage body 61. The tray support stand 68, which stands upright, is attached to the engaging portion 1 of the tray T.
A stopper plate 72 that can be engaged and disengaged with the slide plate 67 is positioned in front of the slide plate 67 to be connected to the tray support stand 68 via a handle plate 69.
A lever handle 75 for sliding operation, which slides the stopper plate 72, is slidable and swingable on the left and right side walls of the box frame 11 corresponding to the position of the tray support stand 68 when the box plate 11 is held in the box frame 11. It was supported (see Fig. 6).

The slide plate 67 has a double plate structure for sandwiching the slide guide base 66 from above and below so that the slide can be smoothly performed, and the tray support stand 68 is provided on the front surface thereof at appropriate intervals in the vertical direction. A stopper plate 72, which has a substantially groove shape when viewed from a plane, is connected to the engaging portion 1 via a joint plate 71 arranged in the. Also, handle plate 6
The reference numeral 9 is attached to the back of the tray support stand 68 so as to project in the left-right direction. For example, an engaging recess 79 at the tip of the lever handle 75 is engaged from below the tray support stand 68.

As shown in FIG. 6 and FIG. 9, the lever handle 75 is supported by a column member 12 which stands on the right and left substantially central portions forming the box frame 11, for example. 12. On the left and right sides, the rear portions of the left and right handle plates 76 pivotally supported in a state where the side wall of the box frame 11 is inserted through the support column 12 through the slide holes 77 that are long in the front and back are connected by the handle arms 78, At the tip of the handle plate 76, the handle plate 6
The engaging recess 79 for engaging with 9 is cut out.

The procedure for holding and releasing the engagement of the tray T with the lever handle 75 and the release thereof are as follows. The cart 60 appears in and out of the box frame 11 and is moved back and forth. To hold or release the engagement with the tray T, the lever handle 75 itself is swung in a substantially horizontal state, and then the engagement recess 79 at the tip of the lever handle 75 is
This is performed by engaging with the handle plate 69 of the grip mechanism 65 in the tray transport carriage 60 and sliding it back and forth. The engagement / disengagement of the grip mechanism 65 with respect to the tray T is released during the circulation movement in the tray rack 10 by the circulation transfer device 20.
When the tray carrier 60 is moved back and forth, the stopper plate 72 of the grip mechanism 65 is engaged with the tray T by sliding the lever handle 75, and the lever handle 75 itself is retracted by the swinging operation. I will keep it.

Interlock with the circular movement of T. By this interlocking, while the tray T reaching the position of the work receiving device 100 during the intermittent raising of the tray T by the ascending / circulating mechanism 21 in the circulation transport device 20, the tray T is pulled out by the pulling-out operation of the pulling-out mechanism 101 on the work receiving rack 15. The work W is discharged from the screen printing machine S side. Then, in the work receiving device 100, after the work W is loaded and placed on the tray T that has been pulled out, the tray T that is lifted and held at the upper position corresponding to the intermittent rising interval of one step in the lifting circulation mechanism 21. Is inserted and placed again on the empty tray shelf 25 in the ascending circulation mechanism 21.

In this way, the tray T is temporarily pulled out during the intermittent raising of the raising and circulating mechanism 21 in the front portion of the tray rack 10, and the work W is placed on the pulled-out tray T.
In the tray rack 10, the tray T is sequentially circulated by the circulation transfer device 20 while the sheet is loaded and placed and then inserted again. That is, the operation of the upper slide mechanism 41 on the upper part of the tray rack 10 moves and slides the tray T, which has reached the uppermost position of the ascending circulation mechanism 21 at the front part, to the uppermost position of the descending circulation mechanism 31 at the rear part, and the descending circulation mechanism. The tray T lowered by 31 moves and slides the tray T which has reached the lowermost stage of the descending circulation mechanism 31 by the lower slide mechanism 51 at the lower part of the tray rack 10 to reach the lowermost position of the ascending circulation mechanism 21, and the ascending circulation. The mechanism 21 again intermittently raises.

When the tray T is circulated in the tray rack 10 and the work of placing the work W on the tray T is completed, the downward movement of the circulating / conveying device 20 is stopped, and the tray handle is operated by operating the lever handle 75. Dolly 6
The grip mechanism 65 at 0 holds the tray T group.
In addition, the operation of the elevating means 85 via the operating means 91 in the lift mechanism 81 raises the support base 82 to the upper position for lifting the tray T group, and separates the tray T from the upper surface of the lower slide mechanism 51. After that, the tray carrier 60 is taken out, a new tray carrier 60 is set in the tray rack 10, and the work is continued. The taken-out tray carrier 60 is placed in an appropriate drying place to dry the work W on the tray T, and if necessary, it is carried into an appropriate dryer to undergo a forced drying operation process. .

Although not shown, the tray rack 1
0 can also be used as a loading machine of the work W to the screen printing machine S together with the tray carrier 60. In this case, the tray rack 10 is arranged on the loading side of the screen printing machine S, and the work receiving device 100 is installed. Connect to the screen printing machine S. Then, the tray transport carriage 60 on which the work W is placed is inserted into each of the trays T, and the tray rack 10 is moved.
The tray T is pulled out by the work receiving device 100 while being circulated by the circulation transfer device 20 therein, and the works W on the pulled-out tray T are sequentially input to the screen printing machine S side.

[0059]

Tray T by the tray lift means 132 incorporated in
By setting the tray T to the upper position, the tray T is raised to the ascending position corresponding to one stage in the ascending / circulating mechanism 21 of the circulating and conveying device 20. Therefore, while the work W discharged from the screen printing machine S side is placed on the tray T, it corresponds to the intermittent rise of the empty tray shelf 25 raised by the raising circulation mechanism 21, and the work time is reduced. It is possible to eliminate waste and improve the efficiency of the whole work.

On the other hand, in the tray carrier 60, a predetermined number of trays T can be stacked in a stack in the front and rear portions partitioned by the grip mechanism 65 which is vertically arranged substantially at the center of both left and right sides. When the tray carrier 60 itself enters the tray rack 10, the circulation carrier 20
The tray T can be placed and set on the tray shelves 25 and 35 of
