Starting position - intermediate position - described in this invention
The three target positions are herein described as supply position B, work position C, and recovery position D, and the turning unit TU is an embodiment of the transfer device according to the present invention. Hereinafter, an example of an automatic feeding device will be sequentially explained.

First, we will explain the details of the work loader WL, which sequentially transfers plates at standby position A onto the conveyor CV at predetermined intervals and feeds them to supply position B, according to Figures 8 and 9. explain.

In the drawings, reference numeral 1 denotes an inclined shutter 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. A slider 2 extends substantially perpendicularly to the shutter surface and guides a plurality of upright plates to the shutter surface, and is also composed of a pair of parallel rails. The shooter 1 and slider 2 are attached to a movable frame 3, and the movable frame 3 is variably supported in the width direction by shafts 5a, 5b, and 5c with respect to the machine frame 4. 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 P are mounted on the slider 2, and are sequentially guided toward the shooter surface by their inclined state, and the plate P in the front row is in a state where it can slide as it is along the shooter surface.

This work loader WL also has a plate P.
An intermittent feed mechanism is provided to control the feed state of the feed. In the drawings, these include a receiving roller indicated by 7 and a feeding claw indicated by 8 and its driving mechanism. The receiving roller 7 is attached to the movable frame 3 in order to resiliently support the lower surface of the plate in the front row located on the first surface of the shooter.
It is supported by a spring 9 and is always urged in the direction of the shutter 1 by a spring 9. The feed pawl 8 is provided so as to be movable up and down along the shutter surface, and to be retractable in the plate direction within a range not exceeding the thickness of the plate P in the front row. That is, the feed claw 8 is
A bracket 1 is attached to a movable block 11 that is movable up and down along a guide shaft 10.
The distal end portion 8a is movable in the direction of the plate and can be moved up and down along the shutter surface as the movable block 11 moves up and down. 13 is
An air cylinder moves the movable bracket 11 up and down, and a rod 13a is connected to the movable block 11 via a bracket 14. Also, 15 is
It is an air cylinder that presses the feed claw 8 from the back side and causes the tip 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 workload loader WP will be explained.

When a plurality of plates P are mounted on the slider 2, depending on the inclination of the slider, the shutter 1
It is in a standby state where it is guided one by one towards the surface. Note that, as shown in FIG. 9, 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 shutter surface, but its lower end is supported by the receiving roller 7 of the intermittent feeding mechanism and continues in a standby state. In this state, when the air cylinder 15 is activated to cause the feed pawl 8 to protrude toward the plate, and the air cylinder 13 is activated to lower the feed pawl, the tip 8a presses the upper edge of the plate P in the front row. , the plate can be slid along the shutter surface against the resilient force of the receiving roller 7. The next plate is the receiving roller 7 again.
is held by. When the feed pawl 8 returns upward, if the air cylinder 15 is stopped, the feed pawl is returned to its old state away from the plate by the return spring 17, so that the feed pawl does not damage the plate during the return upward movement. There isn't.

The slider 2 is positioned abutting against the first surface of the shutter, and as shown in FIG. There are intervals.

FIG. 11 is a schematic diagram showing another example of the intermittent feed mechanism, in which a swinging rod 18 is provided slightly in front of the first surface of the shutter to receive the front plate P, and the second and subsequent plates are placed on the slider 2 or This is a mechanism for fixing the slider with a pin 19 that is slightly retractable between the pair of rails that make up the 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 retracted, 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 shutter surface. In this intermittent feeding mechanism, the receiving roller 7, feeding pawl 8, and air cylinders 13 and 15 in the previous embodiment are unnecessary.

Next, the conveyor CV that feeds 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. 6, 8, and 12.

In this conveyor, the plate conveyance surface is on pulley 2.
It is composed of a pair of endless round belts 22, 22 placed side by side, spanning between 0, 20 and 21, 21. 23, 23 are pulleys 20, 20, 21, 2

24 is attached to the side guide, round belts 22, 2
It has stepped portions 23a, 23a that support the lower surface of 2. Reference numerals 25 and 25 are stoppers that stop the plates 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 CV and the work loader WL.
The side guides 23, 23 have support arms 27, 27,
28, 28 are provided, and base plates 29, 29, 30, 30 to which these supporting arms are fixed are supported or guided by shafts 31, 31, 32, 32 in two stages, upper and lower. That is, support arm 2
7, 27 are fixed to base plates 29, 29, and the base plates 29, 29 are supported by lower shafts 32, 32. Upper shaft 3
1 and 31 only pass through U-shaped grooves 29a and 29a cut from the upper ends of the base plates 29 and 29, respectively. On the other hand, the support arms 28, 28 are fixed to base plates 30, 30, and the support arms 28, 28 are fixed to base plates 30, 30,
0 and 30 are supported by upper shafts 31 and 31. The lower shafts 32, 32 have U-shaped grooves 3 cut from the lower ends of the base plates 30, 30.
It only passes through 0a and 30a. 33 is
This is a bearing that supports the shaft near both ends. Racks are formed at the ends of these shafts 31, 31, 32, 32, and are engaged with pinions 35, 35 provided at both ends of a rotating shaft 34 arranged parallel to the conveyor. 36 is a handle that rotates the rotating shaft 34, and is connected to the rotating shaft by a worm gear 37. Therefore, when the handle 36 is turned to rotate the rotating shaft 34, the upper shaft and the lower shaft are moved in different axial directions.
Accordingly, the side guides 23, 23 also move in opposite directions, so that the width of the conveyor can be changed as appropriate.

Next, details of the rotating unit TU in charge of transfer from the supply position B to the work position C and from the work position C to the collection position D, that is, the transfer device according to the present invention, are shown in FIGS. 1 to 5. I will explain.

In the rotating unit TU, the supply arm 38, the collection arm 39, and the transfer heads 40, 41 provided at the tips of these arms, respectively, are directly involved in transferring the plates. The supply arm 38 has supply position B (starting position) and working position C (intermediate position).
A transfer head 40 holds and transports the plate from the supply position to the working position. The collection arm 39 can reciprocate between a working position C and a collecting position D (destination position), and a transfer head 41 holds the plate and transports it from the working position to the collecting position. The supply arm 38 and the recovery arm 39 are provided on a common pivot shaft 42 so as to be separated from each other at a predetermined angle 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
1 is a holder for the supply arm 38, and 44 is a holder for the collection arm 39, both of which are fitted with a concave-convex fit 45 and are connected with bolts. Rotating axis 42
is held by bearings 47 provided on the upper and lower plates 46, and a nut 48 is screwed onto the end to prevent it from coming off. A swing lever 49 is fixed to the pivot shaft 42 and has a cam groove 49a on its back surface. 50
is a rotating air cylinder attached to the upper and lower plates 46, and a crank lever 5 is attached to its output shaft 50a.
1 is attached, and a pin 51a provided at the tip thereof.
is fitted into the cam groove 49a of the swing lever 49. 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.
2 Furthermore, the supply arm 38 and the collection arm 39 are rotated. 52, 52 are the upper and lower plates 4
A guide shaft that guides the vertical movement of the upper and lower plates 6 is connected to the upper and lower plates by screwing a nut into the upper end screw part inserted through the through hole of the upper and lower plates 46, and the lower end passes through a guide bearing 54 installed in the base 53. The upper and lower plates 46 are supported in the vertical direction, and guide the vertical movement of the upper and lower plates 46. Reference numeral 55 denotes a stay with a threaded portion 55a at one end screwed onto the upper and lower plates 46, and the other end placed on the lifting rod end 56a of the air cylinder 56. Therefore, when the air cylinder 56 is driven to move the rod up and down, the upper and lower plates 46 are moved up and down via the stay 55, and the transfer heads 40, 4 are moved up and down via the stay 55.
1 is also structured to go up and down 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. A rotary sleeve 59 is held at the tip of the supply arm 38 by a bearing 58 held in a housing 57, and a hollow shaft 60 with an air outlet at the upper end is inserted through the rotating sleeve 59. Retainer/rotation member 61
Supported by. 62 is the rotating sleeve 5
This is a locking pin installed at 9. 63 is a suction head screwed onto the lower end of the hollow shaft 60, 64 is a collar inserted into the hollow shaft 60, and 65 is a collar 64.
This is a spring installed between the lower end of the hollow shaft 60 and the lower end of the hollow shaft 60. Reference numeral 66 denotes a lever fixed to the rotary sleeve 59. One end of the link 68 is pivoted 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. ing.

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 through the hollow shaft 60 to suction the plate. Next, the upper and lower plates 46 are raised and rotated to the working position C by the pivot shaft 42. When the upper and lower plates 46 are lowered again and the negative pressure is released, the plates are transferred to the working position. Note that although the plate that has been sucked is rotated and transferred, the rotation of the plate itself is canceled by the action of the lever 66 and the link 68, and the plate is transferred to the work position while maintaining the posture in the supply position. Ru.

Next, explaining the transfer head 41, there is a bracket 70 fixed to the tip of the collection arm 39.
A bearing 72 is held in a housing 71 fixed to the housing 71, and a rotating sleeve 73 is attached to the upper end of the housing 71 with a nut 74 screwed to prevent it from falling off. Reference numeral 75 denotes a mechanical chuck screwed onto the rotating sleeve 74, and is composed of a cylinder portion 76, a chuck body portion 77, a chuck holder 78 operated by the body portion, and a chuck pawl 79. The chuck claw 79 is L-shaped as shown in FIG. 5, and the plate is actually clamped by an attachment 80 attached to the bottom surface of the chuck claw 79. As shown in the figure, the attachment 80 is attached by forming a plurality of attachment holes 79a in the chuck claw 79, inserting bolts planted on the top surface of the attachment 80 into the attachment holes 79a at appropriate positions, and tightening them with nuts.
This allows the attachment spacing to be adjusted to suit the size of the target plate. Reference numeral 81 denotes a lever attached to the chuck main body 77. One end of the link 83 is pivotally supported by a pivot pin 82 provided upright on the upper and lower plates 46, and the other end of the link 83 is rotatably connected by a pin 84. has been done.
Note that air is introduced into the cylinder section 76 from two places: the upper end of the rotating sleeve 73 and the side surface of the cylinder section 75.

The plate transfer operation using this transfer head 41 will be explained. First, by lowering the upper and lower plates 46, the attachments 80 of the chuck claws 79 are positioned on both sides of the plate. In this state, the chuck claw 79 is operated to clamp and hold the plate. Next, the upper and lower plates 46 are raised and rotated to the recovery position D by the pivot shaft 42. Lower the upper and lower plates 46 again and open the chuck claw 79.
The plate will be transferred to the collection position.
Note that the sandwiched plates are 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. The posture remains unchanged from the supply position to the collection position.

In FIG. 2, 50b is a slit disk that detects the rotation angle of the rotary air cylinder 50, and 50c is a limit switch responsive to this, which detects the operating state of the transfer heads 40, 41.
It is designed to give the following instructions.

The plates transferred to the collection position as described above may be simply carried out continuously on the delivery conveyor, but in this feeding device, a predetermined number of plates are further arranged in a line at the collection position. , has a mechanism section to be stored in the magazine.

In FIG. 6, the alignment mechanism is indicated by the symbol AL, which will be explained with reference to FIG. A pair of rotating bars 85, 85 having locking edges 85a, 85a for receiving and arranged in a parallel state, and the received plate are sequentially pushed at a predetermined pitch along the axial direction of the rotating bars. It consists of a feeding mechanism.
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 90 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 a crank 90, and the feed arm 86 is fixed to the crank 90. A rear end portion of the air cylinder 87 is rotatably supported by a receiving metal fitting 91. Therefore, the rotation bar 8
When the plate is horizontally received by the locking edges 85a, 85a of 5, 85, if the air cylinder 87 is driven and the feed arm 86 is operated, the plate is pushed and fed by a predetermined pitch by its tip. It has become a mechanism for

By repeating the above pushing and feeding operation, the plurality of plates are aligned on the rotating bars 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 rotating bars 85, 85 are 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, if a tray is placed close to and below the rotation bar, the plates will be transferred onto the tray in an aligned state. The rotation bar is pivoted by support arms 92, 92, 93, 93 as shown in the figure, and a base plate 9 to which the support arms are fixed.
4, 94, 95, and 95 are supported or guided by the shafts 31, 31, 32, and 32 in the above-mentioned upper and lower two stages. Therefore, the structure is such that the width of the conveyor CV can be adjusted and at the same time the interval between the rotating bars 85, 85 can be adjusted to the same width.

Note that the rotation operation of the rotation bars 85, 85 is performed by an air cylinder and a cam interlocking mechanism. 1st
4 and 15, 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 (not shown in the drawings). (Only the lever and roller attached to one pivot bar are shown). 112 is each roller 111
A flat cam that simultaneously receives the guide shaft 113
It is guided so as to be movable up and down by a guide bearing 114 and 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 rotation bars 85, 8 are rotated.
5 are each adducted at the same time. Furthermore, 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. 6, the tray is designated by the symbol TR;
A rising edge is formed at the end facing the magazine M and at both ends. 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 receiver 100 provided on a lifting base 99 (see FIG. 8). Reference numeral 101 denotes a pulley, around which one end of the drive belt 102 is wrapped. That is, the tray conveyor TC has a bracket 103 attached to this drive belt 102.
(FIG. 8), and when the drive belt 102 is driven by a motor, it is guided by guide shafts 98, 98 and moves forward and backward. Reference numeral 104 is provided to be slidable on the tray conveyor TC, and when the tray TR is pulled out from the magazine M by a tray pusher applied with a spring force in the forward direction on the back side, the tray TR is always pushed against the pull-out pin 96. It is placed in 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 a elevating shaft 106 and a shaft receiver 107 at the front and rear parts, and can be raised and lowered while being guided by the elevating shaft when the elevating rod of the air cylinder provided around the center is activated. It's summery. The magazine M in which trays TR can be stored in multiple stages can be raised and lowered by a lifting device.

Here, the tray TR is transferred to the tray conveyor from the magazine M where the tray TR is full.
The operation of pulling out and storing again using TC will be explained.

First, the drive belt 102 is driven to advance the tray conveyor TC so that 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 1
04 is engaged on the back side with a stopper (not shown) installed upright in the front part of the lifting base 99, and a rear end limiting pin 1 of the tray provided on the tray conveyor.
Its advance is blocked at a position slightly retreating from 08. Taking out the tray TR begins with raising the lifting 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. When the tray conveyor TC is moved backward in this state, the tray pusher 104 acts to press the tray against the pin 96 and position it. Note that the tray is not in the magazine,
Alternatively, if the tray pusher 104 fails to take out, the tray pusher 104 moves forward to near the forward end of the tray conveyor, so if it is associated with the limit switch,
It is possible to detect a mistake in taking out the tray.
The operation of receiving a predetermined number of aligned plates from the rotation bars 85, 85 of the alignment mechanism is performed with the tray being taken out and the elevating base 99 being raised. When this receiving is completed, this tray conveyor TC is advanced by a predetermined pitch in order to receive the next aligned plate on the same tray at a position one row behind. To set the feed pitch,
For example, a tray conveyor is given an advance signal,
When moving forward, a photo sensor or the like detects the change in the relative positional relationship with the lifting base 99 as a reference,
This is done by applying a signal to stop the advance of the tray conveyor when the tray conveyor advances by a predetermined pitch. More specifically, a slit plate with through holes formed at a predetermined pitch is provided on the lifting base 99 side, a photo sensor is provided on the tray conveyor side, and when the photo sensor detects the through holes, the advance of the tray conveyor is stopped. There is a way to create a control mechanism that allows The advance signal for the tray conveyor after receiving the first row of plates 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, the tray conveyor and the trays placed thereon are intermittently fed, 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 almost in the shelf position below the pulled out magazine M, and by further advancing it, it is completely inserted. In this state, when the elevating base 99 is lowered, the tray is transferred to a shelf within the magazine. When the transfer is completed, the tray conveyor is moved backward, the magazine is raised or lowered one step by the lifting device, empty trays are 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.

That is, the automatic plate feeding device described here uses the work loader WL to cut out a plurality of plates onto the conveyor CV at a predetermined interval, and transports the plates to the supply position by the conveyor CV.
The transfer head 40 provided at the tip of the supply arm of the rotating unit TU sucks and holds the plate and transfers it to the working position, and the transfer head 4 provided at the tip of the collection arm transfers the plate in the working position.
At the collection position, a predetermined number of plates are aligned in a line by the alignment mechanism AL, and then transferred to a tray on a tray conveyor, and placed in a predetermined line. This constitutes a continuous automatic feeding device in which a number of sheets are lined up and stored in a magazine.

Transfer device (swivel unit) in this embodiment
The work efficiency is high because the transfer from the supply position (starting position) to the working position (intermediate position) and from the working position to the collection position (destination position) are performed simultaneously. In addition, transportation to the working position is carried out by the suction effect of negative pressure, and transport after the work is carried out by clamping, so for example, when the target is a screen printed board, etc., the optimal This is a grasping method. When targeting other plates, any suitable gripping method can be used, including but not limited to this, and electromagnetic force.

Note that this transfer device is not limited to the case where such an automatic feeding device is incorporated, and it goes without saying that it can constitute an independent transfer device by itself, and can transfer various plates from the starting position to the intermediate position to the destination. It has a wide range of applications as a device for transferring to and from locations.

〔Effect of the invention〕

As described above, the transfer device according to the present invention is capable of simultaneously transporting a plurality of plates sequentially between three positions: a starting position, an intermediate position, and a destination position using a single device, and has extremely high workability. Furthermore, when transferring the plate between positions, the plate is sent in a constant posture without changing its direction, so it is suitable for, for example, re-feeding and performing multiple operations on the same surface.
