Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is a method for arranging a predetermined number of various plates fed one by one from a previous process and sending them to the next process.
This relates to a supply device.

[Conventional technology]

Continuous feeding using a conveyor is commonly used as a method for receiving various plates from a previous process and feeding them to the next process.

[Problem that the invention attempts to solve]

In continuous processing and continuous random collection using a flow process, it is sufficient to pick up multiple plates from the previous process using a continuously driven conveyor and send them to the next process, but they cannot be stored in a magazine. When collecting the plates, it is necessary to arrange the plates fed one by one so that they can be easily stored in the magazine and send them to the next step, for example, a feeding device to the magazine.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a device for arranging and supplying various plates that can align a predetermined number of various plates fed one by one from a previous process and send them to the next process. .

[Means for solving problems]

In this invention, the receiving means and the feeding means for the plates fed from the next stage are individually set, the feeding means aligns a predetermined number of plates on the receiving and stopping means, and after the alignment is completed, The receiver operates a stopping means to send the receiver to the next stage, and its gist is as follows:
A pair of parallel rotating bars each having a locking edge that horizontally receives the plates sent from the previous process; A feeding mechanism in which a feeding arm that pushes and feeds the bar at a predetermined pitch along the axial direction of the bar extends from the feeding end; when a predetermined number of plates are aligned, the feed arm is fed by the number of feeds or the rotating bar is fed by the forward end. When the alignment is detected by the detection means, the feeding mechanism is stopped, the rotating bar is internally rotated, and the aligned plates are dropped by their own weight to proceed to the next step. This is a device for aligning and feeding various plates.

[Effect]

A predetermined number of plates 1 to 10, which are fed to one sheet, are aligned on the rotating bar, and sent to the next process in that aligned state. If the trays are arranged so that they can be transferred in multiple rows, the trays 1 to 1 can be stored in the magazine as they are.

(Example) Hereinafter, an automatic plate feeding device incorporating the plate alignment and feeding device according to the present invention will be described as an example.

FIG. 4 is a route diagram showing the respective feeding positions of plates 1 to 1 in an automatic feeding device incorporating the aligning and feeding device for various plates according to the present invention, from the standby position to the feeding position B to the working position C.
- delivered through a path to a collection location; Figure 3 shows
This is a plan view showing an embodiment of a feeding device that can take such a feeding position.A work loader WL is installed at a standby position A, and is connected to a feeding position B by a conveyor CV. From the supply position B to the work position C and from the work position C to the collection position are handled by the swing unit TU.

First, the plates at the standby position A are sequentially transferred onto the conveyor CV at predetermined intervals and fed to the supply position B.
The details of the workload WL will be explained with reference to FIGS. 5 and 6.

In the drawings, reference numeral 1 denotes an inclined shooter that is aligned in the traveling direction of the conveyor CV and extends at an obtuse angle to the upper surface in the traveling direction, and is composed of a pair of parallel rails. 2
The slider extends substantially perpendicularly to the shooter surface and guides a plurality of plates mounted upright to the shooter surface, and is also composed of a pair of parallel rails. The shooter 1 and the slider 2 are attached to a movable frame 3, and the movable frame 3 is supported variably in the width direction on the machine frame 4 by shafts 5a, 5b, and 5C. The shaft 5a has reverse threads at both ends, and when the handle 6 is rotated, the movable frame 3 is expanded or narrowed in the width direction. A plurality of plates 1 to P are mounted on the slider 2, and are sequentially guided toward the shooter surface by the inclined state thereof, and the plate P in the front row is in a state where it can slide as it is along the shooter surface.

The work loader WL is provided with an intermittent feeding mechanism that roughly controls the feeding state of the plate P. In the drawings, these include a receiving roller indicated by 7, a feeding claw indicated by 8, and its drive R mechanism. The receiving roller 7 is pivotally supported by the movable frame 3 so as to elastically support the lower surface of the play 1 in the front row located on the surface of the shooter 1, and is always urged toward the shooter 1 by a spring 9. The feed pawl 8 is provided so as to be movable up and down along the shooter surface, and to be retractable in the play 1~ direction within a range that does not exceed the thickness of the plays 1~P in the front row. That is, the feed pawl 8 is movable up and down along the guide shaft 10.
The tip portion 8 is pivotally supported by a bracket 12 attached to the
a can move in and out in the direction of the plate, and can move up and down along the shooter surface as the movable block 11 moves up and down. 13 is an air cylinder that moves the movable bracket 11 up and down, and a rod 13a is connected to the movable block 11 via the bracket 14. Also, 15 is the feed claw 8
This is an air cylinder that presses the plate P from the back side and causes the tip portion 8a to protrude toward the plate within a range that does not exceed the thickness of the plate P.

Here, the operating state of the work loader WP will be explained.

When a plurality of plates P are mounted on the slider 2, they are in a standby state where they are sequentially guided toward the shooter 1 surface depending on the tilted state of the slider.

Note that, as shown in FIG. 6, if a push plate 16 is provided at the rear end of the plate P, the guiding state will be smooth. The plate P in the front row is in a state where it can slide along the shooter surface, but its lower end is supported by the receiving roller 7 of the intermittent feed mechanism and continues in a standby state. In this state, the air cylinder 15 is operated to make the feed pawl 8 protrude toward the plate, and then the air cylinder 13 is activated to lower the feed pawl.
By pressing the upper edge of the plate, the plate can be slid along the shooter surface against the resilient force of the receiving roller 7.

The next plate is held by the receiving roller 7 again. When the feed claw 8 returns upward, if the air cylinder 15 is stopped, the return spring 17 returns the feed claw to the concave state away from the plate. There are no words.

The slider 2 is positioned abutting against the surface of the shooter 1, and as shown in FIG. The interval is crotched ().

FIG. 8 is a schematic diagram showing the other side of the intermittent feed mechanism, in which a swinging rod 18 is provided slightly in front of the shooter 1 surface to receive the front plate P, and the second and subsequent plates are placed on the slider 2.
It is a mechanism that is secured by a pin 19 that is slightly protrusive and retractable between a pair of rails that make up the upper or slider. When the swinging rod 18 is pulled in the direction of the arrow by an air cylinder or the like, the front plate slides down along the shooter surface. When the swinging rod 18 returns, if the pin 19 is recessed,
The second and subsequent plates move forward by one plate and are received by the swinging rod 18. By repeating this process, the plate can be slid one by one along the shooter surface.

In this intermittent feeding mechanism, the receiving roller 7, feeding pawl 8, and air cylinder 13, 15 in the previous embodiment are unnecessary.

Next, the conveyor Cv that conveys the plates cut out one by one by the work loader WL to the supply position B while maintaining a predetermined interval will be explained with reference to FIGS. 3, 5, and 9.

This conveyor has a pulley 20.20 on the plate conveyance surface.
The hook is made up of a pair of endless round belts 22, 22 placed side by side across and 21, 21. 23.23 is a side guide to which the pulley 20.20.21.21 and the drive motor 24.24 of the pulley 20.20 are attached, and has stepped portions 23a, 23a that support the lower surface of the round belt 22.22. . 25.25 is a stopper that stops the plate at a fixed position, and 26 is a photo sensor that detects the plate transferred to the supply position and sends a stop signal to the conveyor C2 and the work loader WL.

The side guides 23.23 have support arms 27.27.28.
28 is provided, and the base plate 29, 29, 30, 30 to which this supporting arm is fixed serves as a shaft 31.3 in upper and lower stages.
1.32.32 supported or guided.

That is, the support arms 27.27 are attached to the base plate 29.27.
29, and the base plate 29.2 is supported by the lower shaft 32.32. Upper shaft 3
1.31 only passes through U-shaped grooves 29a, 29a cut from the -F end of the base plate 29.29.

On the other hand, the support arm 28.28 is fixed to a base plate 30.30, which is supported by an upper shaft 31.31. Bottom shirts 1-32
．． 32 is a U-shaped groove 30a cut from the lower end of the base plate 30.30.

It only passes through 30a. 33 is a bearing that supports the shaft 71 in the vicinity of both ends. These shafts 31
．． 31, 32, and 32 are formed with a rack, and pinions 35, 35 provided at both ends of a rotating shaft 34 arranged parallel to the conveyor mesh with each other. 36 is rotation @34
It is a handle that rotates, and is connected to the rotating shaft by a worm gear 37. Therefore, when the handle 36 is turned to rotate the rotation shaft 34, the upper shaft and the lower shaft are moved in different axial directions, and accordingly, the side guides 23 and 23 are also moved in opposite directions. , the conveyor width can be changed as appropriate.

Next, details of the turning unit TU, which is in charge of transferring from the supply position B to the work position C and from the work position C to the collection position, will be explained with reference to FIGS. 11 to 15.

In the rotating unit TU, the supply arm 38, the recovery arm 39, and the transfer heads 40 and 41 provided at the tips of these arms are directly involved in transferring the plates.
It is. The supply arm 38 can reciprocate between the supply position B and the work position C, and the transfer head 40 holds the play 1- and transports it from the supply position to the work position. The three collection arms can reciprocate between the work position C and the collection position, and the transfer head 41 holds the plays 1 to 1 and transports them from the work position to the collection position. The supply arm 38 and the recovery arm 39 are separated from each other by a certain angle on a common pivot shaft 42 to enable the above-mentioned transfer.

In other words, while the supply arm moves from the supply position to the work position, the collection arm simultaneously rotates at an angle from the work position to the collection position. 43 is a holder for the supply arm 38, and 44 is a boulder for the collection arm 39, both of which are fitted 45 with a concave-convex fit and are connected with bolts. The pivot shaft 42 is held by bearings 47 provided on the upper and lower plates 46, and a nut 48 is attached to the end to prevent handling.
is screwed on. A swing lever 49 is fixed to the pivot shaft 42 and has a cam groove 498 on its back surface.

50 is a rotary air cylinder mounted on the upper and lower plates 46, and a crank lever 51 is attached to its output shaft 50-a, and a pin 51a provided at the tip thereof is inserted into the cam groove 49a of the swing lever 49. It is fitted. Therefore,
When the air cylinder 50 is driven, the crank lever 51 rotates via the output shaft 50a, and the swing lever 49 is rotated, so that the pivot shaft 42, as well as the supply arm 38 and the collection arm 39, are rotated. 52. 52 is a guide shaft that guides the vertical movement of the upper and lower plates 46, and is connected to the upper and lower plates by screwing a nut into the upper end screw portion inserted through the through hole of the upper and lower plates 46, and the lower end is installed on the base 53. The guide bearing 54 is supported through the guide bearing 54.
It guides the up and down movement of the upper and lower plates 46. 55 is a stay with a threaded portion 55a at one end screwed to the upper and lower plates 46, and the other end is connected to the lifting rod end 56a of the air cylinder 56.
It is placed on top of. Therefore, when the air cylinder 56 is driven to raise and lower the iron, the upper and lower plates 46 are raised and lowered via the stay 55, and the transfer heads 40 and 41 are also raised and lowered at the same time. Note that the distance of the stay 55 to the rod end 56a can be adjusted by loosening the nut 55b.

Next, the transfer head 40 will be explained.
Bearing 5 held in housing 57 at the tip of 8
A rotary sleeve 59 is held by 8, and a hollow 'N160 whose upper end opening is an air outlet is inserted through the rotary sleeve 59, and is supported by a throw stopper/rotation stopper member 61. 62
is a rotation prevention pin implanted in the rotating sleeve 59. 6
3 is a suction head screwed onto the lower end of the hollow shaft 60, 64 is a collar inserted into the hollow @60, and 65 is a spring installed between the collar 64 and the lower end of the hollow @1160.

Reference numeral 66 denotes a lever fixed to the rotating sleeve 59. One end of the link 68 is pivotally supported by a pivot pin 67 that stands upright on the upper and lower plates 46, and the other end of the link 68 is rotatably connected by the pin 69.

The plate transfer operation using the transfer head 40 will be explained. First, by lowering the upper and lower plates 46, the suction head 63 is brought into contact with the plate at the supply position B. In this state, negative pressure is generated in the suction head 63 via the hollow shaft 60 to suction the plate. Next, the upper and lower plates 4
6 is raised and rotated to the working position C by the pivot shaft 42.

If the upper and lower plates 46 are lowered again and the negative pressure is released,
The plate will be transferred to the working position. Hey,
The attracted plate is rotated and transferred, but the lever 66
The rotation of the plate itself is canceled by the action of the link 68, and the plate is transferred to the working position while maintaining the posture at the supply position.

Next, the transfer head 41 will be explained.
A bearing 72 is held in a housing 71 fixed to a bracket 70 fixed to the tip of the rotary sleeve 73, and a rotating sleeve 73 is attached to the upper end with a nut 74 screwed to prevent it from falling off.

Reference numeral 75 denotes a mechanical chuck screwed onto the rotary sleeve 74, and includes a cylinder part 76, a chuck main body part 77, a chuck holder 78 operated by the main body part, and chuck claws 79. In addition, the chuck claw 79
As shown in FIG. 15, it has an L-shape, and the play 1- is actually clamped by an attachment 80 attached to the bottom surface of the chuck claw 79. To attach the attachment 80, as shown in the figure, the chuck claw 79
A plurality of mounting holes 79a are formed in the top surface of the attachment 80, and bolts planted on the top surface of the attachment 80 are inserted into the mounting holes 79a at appropriate positions and tightened with nuts. It is possible to adjust the spacing.

Reference numeral 81 denotes a lever attached to the chuck main body 77, one end of which is pivotally supported by a pivot pin 82 provided upright on the upper and lower plates 46, and the other end of a link 83 is rotatably connected to a pin 84. ing. Note that air is introduced into the cylinder part 76 from two places: the upper end of the rotating sleeve 73 and the side surface of the cylinder part 75.

The plate transfer operation using the transfer head 41 will be explained. First, by lowering the upper and lower plays 1-46, the attachments 1-80 of the chuck claws 79 are positioned on both sides of the plate. In this state, the chuck claws 79 are operated to clamp and hold the plate. Next, the upper and lower plates 46 are raised and rotated by the pivot shaft 42 to the collection position. When the upper and lower plates 46 are lowered again and the chuck claws 79 are opened, the plates are transferred to the recovery position.

Note that although the clamped plate is rotated and transferred, the rotation of the plate itself is canceled by the action of the lever 81 and the link 83, and the plate is transferred to the collection position while maintaining the posture in the working position.

In other words, the plate at the supply position is transferred to the work position and the plate at the work position is transferred to the collection position by the lifting, rotation, suction, and clamping operations of the rotating unit TU, and the posture of the plate is , remains unchanged from the supply position to the collection position.

In addition, in FIG. 12, 50b is a slit disk that detects the rotation angle of the rotating air cylinder 50, and 50C is a
A limit switch responsive to this transfer head 40.
41 is detected, and the next instruction is given.

The plate transported to the collection position as described above is
The plates are continuously carried out using a carry-out conveyor (although it is also possible to use a pull-out conveyor, in this embodiment, a predetermined number of plates are roughly arranged in a line at the collection position and then stored in a magazine. .

In FIG. 3, the symbol @AL indicates the aligning and feeding device according to the present invention, which will be explained with reference to FIG. Locking edges 85a, 8 that are received horizontally at the edges
5a, a pair of rotating bars 85.5a arranged in parallel.
85, and a feeding mechanism that sequentially pushes and feeds the received plate at a predetermined pitch along the axial direction of the rotating bar. The feeding mechanism is installed below both rotating bars 85, 85, and has a feeding arm 86 whose tip extends between both rotating bars to a plate receiving position, and an air cylinder 87 that drives this feeding arm. The two are connected via a crank 9o having one end attached to a rotating shaft 89 mounted between bearings 88. That is, the rod end of the air cylinder 87 is rotatably connected to the crank 90, and the feed arm 86 is fixed to the crank 90. The rear end of the air cylinder 87 is rotatably supported by a metal fitting 91 . Therefore, the rotation bar 85.85
When the plate is received in a horizontal state by the locking edges 85a, 85a, if you drive the ascinnator 87 and operate the feed arm 86, the plate is pushed forward by a predetermined pitch by the tip of the mechanism. It becomes.

By repeating the above pushing and feeding operation, a plurality of plays 1 through are aligned on the rotation bar 85.85. This alignment state is detected by the position of the plate located at the forward end or by the number of times the feed arm 86 is fed, and the feed mechanism is stopped and the rotation bar 85.85 is internally rotated. When the rotation bar internally rotates, the locking state by the locking edge is released, and the plates fall downward under their own weight while remaining aligned. Therefore, relays 1 and 2 are arranged below the rotation bar, so that plays 1 and 1 are transferred onto the tray in an aligned state.The rotation bar is supported as shown in the figure. The base plate 94.94.95.95, which is pivotally supported by the arm 92.92.93.93 and this support arm is fixed, connects to the above-mentioned upper and lower two-stage shafts 31.3, 1.32.32'c''.
supported or guided. Therefore, while adjusting the width of conveyor C■, the rotation bar 85.8 is kept at the same width.
It has a structure that allows you to adjust the spacing between the 5.

In addition, rotation bar 85.85 times 81! ! The operation is performed by an air cylinder and a cam interlocking mechanism. Figures 1 and 2
In the figure, reference numeral 109 denotes a lever connected at one end to the shaft end of each rotating bar 85, 85, and a roller 111 is attached to the other end via a shaft 110.
In the drawing, the lever and row chisel attached to one of the pivot bars are shown). 112 is each roller 111
It is a flat cam that simultaneously receives the cams, and is guided so as to be raised and lowered by a guide shaft 113 and a guide bearing 114, and is raised and lowered by an air cylinder 115. Therefore, when the air cylinder 115 is driven to move the flat cam 112 upward, the lever 109 is rotated via each roller 111, and the rotating bars 85, 85 are internally rotated at the same time. Also, when the flat cam is lowered, it returns to its previous state.

Next, a description will be given of a tray conveyor that receives plates transferred in an aligned state on a tray and stores the trays in a magazine.

In FIG. 3, the tray is designated by the symbol TR, and the end facing the magazine M and both ends thereof are formed with rising edges. The tray conveyor is designated TC and extends from the front end where the tray pull-out pin 96 is located to the rear end designated 97. 98.98 is a guide shaft of the tray conveyor TC, which is supported by a shaft support 100 provided on a lifting base 99 (see FIG. 5). Reference numeral 101 denotes a pulley, around which one end of the drive belt 102 is wrapped. That is, the tray conveyor TC is driven by this drive belt 102.
When the drive belt 102 is driven by a motor, it is guided by guide shafts 98 and 98 and moves forward and backward. 104 is
When the tray TR is pulled out from the magazine M by a tray pusher that is slidable on the tray conveyor TC and has a spring force applied to it in the forward direction on the back side, the tray TR is always
R is pressed against the pull-out pin 96 to take a fixed position. 105 is a sliding guide for the tray pusher 104.

The elevating base 99 is supported so as to be movable up and down by an elevating shaft 106 and shafts 71 to 107 at the front and rear parts, and when the elevating rod of the air cylinder provided around the center is operated, the elevating base 99 moves up and down while being guided by the elevating shaft. It is possible.

The tray TR@magazine M, which can be stored in multiple stages, can be raised and lowered by a lifting device.

Here, the operation of pulling out the tray TR for one sheet from the magazine M when the tray TR is full by the tray conveyor TC and storing it again will be explained.

First, the drive belt 102 is driven to advance the tray conveyor TC, and the front half enters the magazine. The entry position within the magazine is below the tray to be pulled out and between it and the next tray. In this approach state, the tray pusher 104 engages on the back surface with a stopper (not shown) erected at the front part of the lifting base 99, and the rear end limit pin of the tray provided on the tray conveyor. Its advance is blocked at a position slightly retreating from 108. Taking out the tray TR begins with raising the elevating base 99 and lifting the tray TR from the shelf in the magazine M. At this time of lifting, the tray TR is located between the front and rear pins 96 and 108 of the tray conveyor TC. If the tray conveyor TC is moved backwards in this state,
The tray pusher 104 acts to press the tray against the pin 96 and position it. Note that if the tray is not in the magazine or if the tray is taken out unsuccessfully, the tray pusher 104 advances to the vicinity of the forward end of the tray conveyor, so if it is associated with a limit switch, the mistake in taking out trays 1 to 10 will be detected. be able to.

The operation of receiving a predetermined number of aligned plates from the rotation bar 85.85 of the alignment mechanism is performed by taking out the tray,
This is performed while the elevating base 99 is raised. When this reception is completed, this 1 to ray conveyor TC is advanced by a predetermined pitch in order to receive the next aligned plate on the same tray at a position behind the -row. To set the feeding pitch, for example, when a forward signal is given to the tray conveyor and the tray conveyor moves forward, a change in the relative positional relationship with the lifting base 99 is detected by a photo sensor, etc., and the tray is moved forward by a predetermined pitch. This is done by applying a signal to stop the advance of the conveyor.

More specifically, plates 1 to 3 with through holes formed at a predetermined pitch are provided on the lifting base 99 side, and a photosensor is placed on the tray conveyor side.When the photosensor detects the through holes, There is a method of using a control groove to stop the advance of the tray conveyor.

The advance signal for the first to ray conveyors after receiving the plate in the - row and the re-advance signal for the second and subsequent rows can be obtained from the number of times the feed arm 86 of the feed mechanism is fed. In this way, intermittent feeding of the trays 1 to 1 and the trays placed thereon is carried out, and for example, three or four rows of plates are received on the tray. At the time when the last row of plates is received, the tray is placed in the pulled out magazine M.
It is almost in the shelf position below the , and it can be completely inserted by moving it forward roughly. In this state, when the elevating base 99 is lowered, the tray is transferred to a shelf within the magazine. Once the transfer is complete, move the tray conveyor back,
The magazine is raised or lowered one step by a lifting device, an empty tray is taken out from the next shelf by the same operation as above, and the alignment and storage is repeated. In this way, when the magazine is full with the trays on which the plates have been arranged and transferred, the magazine is taken out and replaced with a new magazine containing empty trays.

In other words, the automatic plate feeding device described here is
The work loader WL cuts out a plurality of plates onto the conveyor Cv at predetermined intervals, the conveyor C■ transports the plates to the supply position, and the transfer head 40 provided at the tip of the supply arm of the turning unit TtJ cuts the plates At the same time, the plates at the working position are clamped and held by the transfer head 41 provided at the tip of the collection arm, and transferred to the collection position. At the collection position, the plates are aligned and fed. Device Am constitutes a continuous automatic feeding device that arranges a predetermined number of plates in a line, transfers them to a tray on a tray conveyor, arranges them in a predetermined number of rows, and stores them in a magazine. be.

In the work loader, the plate is sent toward the chute by the tilted state of the slider, and is transferred onto the conveyor by sliding on the chute in the tilted state, so that cutting out of the plate is extremely light and smooth.

For example, in the method where plates stacked vertically are stacked one after the other from the bottom, the actual kicking force required changes as the number of plates decreases, but the combined kicking force is required when the heaviest weight is applied. However, (there was a problem that the condition was inconsistent because it was buri).

Also, if you feed the plate vertically, the weight will not be reduced, but you will need additional force to feed it, and if you drop it vertically, the posture will not be fixed, making it impossible to obtain a constant feeding condition. There are some difficulties. However, the above workload W[
Since the plates are arranged in an inclined manner, there is little difference in weight between the front and rear plates.Furthermore, the receiving roller that receives the front plate is placed at a slightly lower position, allowing it to be received away from the overall weight. Therefore, the spring force applied to the receiving roller should be enough to overcome the self-weight of the plate.

Therefore, the cutting state of the plate is extremely stable, and no excessive force is applied to the plate, so there is an advantage that the plate is not damaged.

Since the conveyor CV uses round belts arranged in parallel, it differs from the flat belt 1 that contacts the entire surface of the plate.
The conveyance condition becomes stable.

The rotating unit simultaneously moves from the supply position to the work position and from the work position to the collection position, so it has high workability. In addition, transportation to the work position is done by suction due to negative pressure, and transport after work is done by clamping, so for example, when the target is a screen printed board, etc.
This is the optimal gripping method depending on before and after printing. When covering another plate as a target, any suitable gripping method may be used, including but not limited to this, and electromagnetic force.

Further, when the plate is transferred from the supply position to the collection position, the plate is sent in a fixed posture without changing its direction, so that it can be sent again, for example, when performing multi-width work at the same time.

It should be noted that this arrangement 11 supplying device is not limited to being incorporated into such an automatic feeding device, but it is natural that it can constitute an independent arrangement and feeding device by itself, and it is possible to arrange a predetermined number of various plates in an aligned state. As a feeding device, its range of applications is wide.

[Effects of the Invention] As described above, the alignment and feeding device according to the present invention is capable of aligning a predetermined number of plates fed one by one and then feeding them to the next stage, and collecting the plates one after another into a magazine. It is extremely effective in this case.
