Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler feeder for feeding a large number of U-shaped staples cluttered in a hopper to another device while being aligned in a line.

[0002]

2. Description of the Related Art As a stapler of this type,
A hopper for accommodating a large number of U-shaped staples is provided with a scooping plate that moves up and down through a slit provided at the bottom of the hopper, and the stapling in the hopper is scooped by the upward movement of the scooping plate. There is one in which the upper edge of the plate is scooped up in a straddle-like manner and the scooped up staple is supplied toward the next stage (for example, see Japanese Utility Model Publication No. 49-15113). In such a stapler supply device, since the staples scooped up in a straddle shape are aligned on the upper edge, the staples can be supplied to the next stage in the aligned state.

[0003]

However, in the case of the above scooping, there is a case where another staple is piled up on the staple that straddles the upper edge to straddle. Therefore, in order to select the stacked staples in the middle of the rail that is slanted so as to slide down the staples that straddle the scooping plate for the supply to the next stage,
There is one in which a sorting piece is fixedly arranged on the upper side of the rail and is attempted to be removed by that (for example, Jikho Sho 47-106).
Japanese Patent No. 78). However, if a large number of staples straddled and aligned on the upper edge of the rail and staples further straddled on it are mixed, the legs of those staples are in a state of tightening and biting the side surface of the rail. If the sorting piece is fixed, the staple will stop there, and it will not be able to slide down along the rail, and the stacked staples will be removed as well as the removal of stacked staples. There was a problem that supply was also delayed. Therefore, I thought about vibrating or moving the sorting piece along the rail, but in order to guide the sorted staple, a guide must be connected as shown in the figure. For that reason, there is a situation in which a sorting piece along the rail must be fixed to a supporting member as shown in the figure, and there is a problem that the structure cannot be easily improved.

The present invention has been made in order to solve the above-mentioned problems (technical problems) of the prior art, and scoops up the cluttered staples in the hopper into an aligned state by a scooping plate to align the staples. Can be supplied to the next stage in the state,
In addition, even if there are other harmful staples stacked on the staples that are scooped up in an aligned state on the scooping board, it is possible to move them along the upper edge of the inclined scooping board. The pulling claw that moves from the bottom to the top enables positive removal in the form of a pull-out, and without removing the harmful effect of stopping or reversing the alignment staple, the removal of the harmful staple is possible. It is an object of the present invention to provide a stapler feeder that enables stable and continuous supply of aligned staples.

Next, the manufacturing of the insulating staple by the insulating staple manufacturing apparatus having the above structure will be described. The chain 7 is continuously moved in the direction of the arrow by the rotation of the drive wheels 5, 6. Further, in the feeding device 15, a large number of staples in the hopper 16 are guided by the guide rail 1 by an operation described later.
Slide down with 9 aligned. Then, by the operation of the embossing piece 21 synchronized with the movement of the conveyor 4, the guide rail 19
The upper staples s are struck from the lower end of the rail 19 toward the mounting portions 12 one by one, and the staples S are mounted on the mounting portions 12 one after another with their head heights aligned. The step S mounted on the mounting unit 12 reaches the horizontal moving section on the lower side of the conveyor 4 as the conveyor 4 moves, and the head of the step S is in a downward state there.

When the staple S reaches the position of the coating liquid applying device 24, the elevating means 26 in the coating liquid applying device 24.
The coating liquid tank 27 is moved upward by the upward movement of the liquid tank table 25. In the upward movement process, the engaging portion 34 of the connecting member 33
Engages with the chain roller 8 as shown in FIG. When the engagement is achieved, the coating liquid tank 27 moves on the liquid tank table 25 in the same direction as the conveyor 4 at the same speed. In this state, the coating liquid tank 2
The upward movement of 7 is still continued, and the head of the staple attached to the attachment portion 12 enters the coating liquid 30 in the coating liquid tank 27 straight downward. Then, when the coating liquid tank 27 moves up to the position where the head of the staple S is immersed in the coating liquid 30 to a predetermined depth, the upward movement of the coating liquid tank 27 by the elevating means 26 is stopped. At this position, the coating liquid tank 27 is held for a certain period of time so that the coating thickness of the staple becomes a predetermined thickness. Thereafter, the elevating means 26 moves the coating liquid tank 27 downward. The downward movement causes the staple S to be lifted straight upward from the coating liquid 30. And Staple S
After the liquid has flowed out of the coating liquid 30, the engagement between the engagement portion 34 of the connecting member 33 and the chain roller 8 is released, and the coating liquid tank 27 stops its lateral movement. After this state, the coating liquid tank 27 is returned to the original position in the direction opposite to the moving direction of the conveyor by the pushing of the driven piece 35 by the returning means 37.

The operation of the coating liquid depositing device 24 as described above is repeated, and the coating liquid is deposited by the same action as described above on the staples that successively arrive at the position of the coating liquid depositing device 24 as the conveyor 4 moves. Is done. In that case, the upward movement and downward movement of the coating liquid tank 27 and the progress in the moving direction of the conveyor and the return in the opposite direction are performed by a large number of staples that are successively conveyed by the conveyor once (or even twice or more). Possible) Corresponding to the movement of the conveyor so as to be immersed in the coating liquid. As the means, the elevating mechanism and the returning mechanism of the coating liquid tank 27 are mechanically linked with the conveyor, or the elevating mechanism and the returning mechanism are controlled by a timer. In the case of repeating the above, the coating liquid 3 is stored in the coating liquid tank 27.
Since a constant amount of 0 is held and the liquid surface is kept constant, and the rising height of the coating liquid tank 27 by the elevating means 26 is constant, the staple is always immersed in the coating liquid 30 to a constant depth. . As a means for holding the coating liquid 30 in a constant amount, for example, an electric liquid level sensor is attached to the coating liquid tank 27, the sensor detects the height of the liquid surface, and the coating liquid tank 27 receives the detection signal. A pump for supplying the coating liquid is automatically controlled to keep the height of the liquid surface constant.

The stapling to which the coating liquid is attached as described above reaches the location of the wiping device 41 as the conveyor 4 horizontally moves, where the coating liquid on the upper surface of the head is wiped off, and further reaches the solidification furnace 42 for coating. The liquid is dried and solidified.

The insulating staple S2 thus produced reaches the location of the detaching device 43 as the conveyor 4 moves. In the disengagement device 43, when the follower 52 is in contact with the low step portion of the cam 48 as shown in FIG. 1, the disengagement piece 45 is locked by the urging force of the return spring 56.
Is held in position along. In this state, when the insulating staple S2, which is a product, moves over the detachable piece 45 as shown in FIG. 1 or FIG. 3B by the movement of the conveyor 4, the cam 48 that rotates in synchronization with the movement of the conveyor 4 causes As shown in FIG. 3A, the separation piece 45 is swung rapidly in the direction of the arrow 60, which is separated from the conveyor 4. That is, cam 4
8, the push-up lever 50 is rapidly pushed up as shown in the figure, and the interlocking lever 55 is pushed up via the transmission rod 53, so that the detachable piece 45 rapidly swings in the direction of arrow 60. Due to such a sudden movement of the detaching piece 45, the insulating staple S2 attached to the mounting portion 12 is pulled out from the attaching portion 12 instantaneously, that is, the insulating coating on the steple S2 does not slide sideways with respect to the detaching piece 45. Breakaway piece 4
Immediately after 5 suddenly moves in the direction of arrow 60 as described above, the follower 52 of the push-up lever 50 comes into contact with the lower step portion of the cam 48 again, and the separating piece 45 is urged by the return spring 56. It is swung rapidly in the direction of the arrow 61, and is returned to a position along the locking body 11 before the next insulating staple S2 reaches the position of the tip of the separating piece 45.

The above-described operations are accompanied by the endless movement of the conveyor 4, and are denoted by reference numerals 15, 20, 24, 41, 42 and 43, respectively.
In the apparatus shown by (1), the insulating staple is continuously manufactured by repeating the same process.

Next, the stapler feeder 15 will be described with reference to FIGS. As shown in FIGS. 7 and 8, the hopper 1
6 is configured by connecting and integrating a plurality of hopper elements 65, 66, 66 ... With a plurality of bolts 69 in a state in which spacers 67, 68 are interposed between the hopper elements 65, 66, 66, ... The wall 71 is provided with slits 72 and 73 which are continuous with each other. These slits 72, 7
The width of 3 is formed slightly larger than the thickness of the scooping plate 17, so that the scooping plate 17 can smoothly move up and down. The scooping plate 17 is pivotally attached to the hopper 16 using a pivotally attached shaft body, for example, a pin 74. Reference numeral 75 denotes the upper edge of the scooping plate 17. About half of the upper edge 75 on the free end side of the scooping plate 17 is provided so that the U-shaped staples cluttered in the hopper 16 can be scooped up with certainty. On the other hand, at the upper edge 75, a half portion 77 on the base side of the scooping plate 17 is provided with a U-shape so that the scooped scoop can be stably guided while being straddled. The width of the leg is slightly smaller than the distance between the legs of the staple.

Next, 80 is a guide rod provided in parallel with the upper edge 77, and one end and the other end thereof are supported by supporting pieces 81 and 82 attached to the scooping plate 17. Reference numeral 84 denotes an advancing / retreating member mounted on the guide rod 80 so as to be capable of advancing / retreating, and 85 denotes an extraction claw provided for the advancing / retreating member 84. As shown in FIG. 4, the tip end portion in the advancing direction is formed thin and the tip end is in an open state. As shown in FIG. 5, one head portion of the U-shaped staple is opposed to the upper edge 77 with a gap G through which the head portion can pass. Next, reference numeral 86 indicates a mechanism for advancing and retracting the extraction claw 85. 87 is a receiving piece in the mechanism, which is attached to the hopper 16. Reference numeral 88 is a member provided on the advancing / retreating member 84, and is constituted by a roller so that the friction when contacting the receiving member 87 becomes small as shown in FIG. Next, 90 is a tool attached to the tip of the piston rod of the lifting cylinder 18, which comprises a holding body 91 and a roller 92 rotatably held by the holding body 91, and the roller 92 is the lower edge of the scooping plate 17. It comes into contact with. Next, 93 shown in FIG. 8 is a mountain-shaped partition member mounted between the plurality of slits 72 arranged in parallel on the bottom wall 70 in the hopper 16,
Denoted by 94 and 95 are inclined walls for guiding the staples in the member, respectively, which are inclined so as to guide the staple toward each slit.

Next, the operation of the staple supply device 15 will be described. A large number of U-shaped insulating staples are cluttered in the hopper 16. The extension of the cylinder 18 causes the scooping plate 17 to move from the state of FIG. 5 to the state of FIG.
Is raised like. During this ascending process, the hopper 16
The inner staple is scooped up by the upper edge 75 of the scooping plate 17, mainly by the upper edge 76, so that the scooping plate 1
As it moves up, it slides toward the upper edge 77. The staple S that has moved to the upper edge 77 further slides down the upper edge 77 and moves to the guide rail 19, and slides down the guide rail 19 in a seated state and is supplied toward the launching device.

When the scooping plate 17 scoops up the staple as described above, there is a case where another staple S'is mounted on the staple S mounted on the upper edge 76 as shown in FIG. is there. Staple S in such a state,
When S ′ reaches from the portion of the upper edge 76 to the portion of the upper edge 77, the upper edge 77 of the scooping plate 17 in those staples.
In some cases, the leg portions Sa located on both sides of the portion S sandwich the scooping plate 17 from both side surfaces, and the frictional resistance there increases to cause the staple to stop while straddling the upper edge. However, such a staple S'is removed by the extraction claw 85 as described below. That is, when the scooping plate 17 rises from the state shown in FIG. 5, the contact member 88 contacts the receiving member 87 in due course. Then, when the scooping plate 17 is still raised and is in an inclined state in which a large number of staples are slid down as shown in FIG. 4, the contact member 88 is pushed by the receiving member 87, so that the advancing / retreating member 84 is moved to the guide rod 80. Along the direction of the arrow in FIG. By the forward movement of the stapler in the direction opposite to the downhill direction, the extracting claw 85 vigorously withdraws the staple S'from the upper edge 77 as shown in FIG. As a result, the upper edge 7
Only the properly aligned staples S remain in 7, which slides down into the guide rail 19. Next, as the cylinder 18 contracts and the scooping plate 17 descends as shown in FIG.
Is returned to the original position as shown by the biasing force of the return spring 89. In this case, since the tip of the extraction claw 85 is in the downward state, the extracted staple S'is not included in the extraction claw 8
It falls off from 5, and becomes ready to be scooped again in the hopper 16.

When the scooping plate 17 descends as described above,
A large number of staples in the hopper 16 are guided by the inclined walls 94 and 95 and slide down in the direction of arrow 96 to fill the spaces above the slits 72 after the scooping plates 17 have descended. Therefore, when the scooping plate 17 moves up again, the respective upper spaces ascend the space filled with the staples, so that it is possible to reliably scoop up a large number of staples. The inclined side wall 65a of the hopper element 65 also performs the same function.

Next, FIGS. 9 and 10 show different embodiments of the stapler feeder. In this example, the extraction claw is provided on the hopper side. In the figure, the guide rod 80e is attached to the hopper 16e. A cylinder 97 attached to the hopper 16e is used as the advancing / retreating mechanism 86e. The extraction claw 85e is pivotally attached to the advancing / retreating member 84e with a pin 98, and is tilted by a solenoid 99. With such a structure, the upper edge 77e and the guide rod 80e are in a state where the scooping plate 17e is raised to the upper limit.
Are parallel to each other, and the interval between the upper edge 77e and the extraction claw 85e is the interval through which one head of the staple is passed. In this state, the claw 85e moves back and forth along the upper edge 77e due to the expansion and contraction of the cylinder 97. Also, the extraction claw 85e by the solenoid 99 is shown in FIG.
By the tilting like 0, the staples hooked on the claw 85e are removed from the claw 85e. In addition, parts that are considered to be the same or equivalent in configuration to those in the previous figure in terms of function are denoted by the same reference numerals as those in the previous figure with the letter e added to omit redundant description.

[0025]

As described above, according to the present invention, when the staple S is supplied, the scooping plate 17 is lifted to scoop up a large number of staples cluttered in the hopper 16. And they are scooping board 17
Since they are lined up in a straddle shape on the upper edge of the stapling, there is an effect that those scooped staples can be supplied to the next stage in an aligned state,

In the case of the above scooping, the scooping plate 1 as shown in FIG.
Even when another staple S ′ is piled up and straddles on the staple S straddling the upper edge of No. 7, the piled staples S ′ are moved forward by the extraction claws 85 so that the extraction claws 85 can be removed. Thus, there is a feature that it can be pulled out as shown in FIG. 4, and only one layer of the staples directly straddling the scooping plate 17 can be present on the upper edge of the scooping plate 17. As a result, when the scooped staple is supplied to the next stage, the transition of the staple can be smoothly performed without being delayed on the way like the above-mentioned conventional technique, and the supply of the aligned staple can be stabilized. There is an advantage that can be continued.

Further, in the present invention, the scooping plate is arranged so as to be movable along the upper edge when the scooping plate is in an inclined state in which the scooping plate is raised and slides down a large number of staples, and the scooping plate is directed toward the guide rail. To advance the narrow tip of the above-mentioned extraction claw under the head of the steple, which is further straddled over a large number of steps in the downhill posture, along the upward slope, in the opposite direction of the downhill direction. Since the staples that are straddled by the above are extracted and collected on the extraction claws, firstly, even if the downhill speed of the staple row S aligned with the upper edge 77 of the scooping plate 17 is slow, the extraction claws are 85
Has the characteristic of going backwards, so as shown in Fig. 4, the staple S
Actively and vigorously the staple s's that are straddled on the top (without stopping the downhill of the staple row)
There is an effect that can be extracted. Secondly, the extraction claw 85
4, the staple row S aligned with the upper edge 77 of the scooping plate 17 is in a downhill posture even if it is moved backward, so that there is a fear that the withdrawal claw 85 may move backward to come off the upper edge 77. Instead, it has the effect of smoothly guiding you to the next stage.

Further, according to the invention of the present application, a partitioning member having a mountain-shaped cross section for partitioning the upper slits from each other is provided between the plurality of slits in the hopper in a rising manner. Since both side surfaces of the partition member are slanted walls so as to guide the staples to the upper side of each slit, it is of course effective to scoop out the staples by using a plurality of scooping plates 17. That is, even with such a configuration for improving efficiency, when a plurality of scooping plates 17 and 17 are lifted, a group of U-shaped staples on the adjacent slits 72 and a U-shaped immediately above each of them. The entanglement with the staple group is blocked by the partitioning member 93 to be distinguished from each other, which has an epoch-making effect in lightly lifting the respective scooping plates 17, 17.

Scoop the stepper in the hopper to the upper edge of the scooping plate in a straddle shape, rotate the scooping plate to rotate the scooping plate, and tilt the upper edge to slide down the inclined upper edge and guide the next stage. In a stapler supply device adapted to supply to a rail, a hopper having a withdrawal claw for upwardly withdrawing the staples further straddling a plurality of staples aligned and straddling the upper edge of the scooping plate. The extraction claw has a narrow tip in the direction of travel, the tip is open, and the top edge of the U-shaped staple is separated from the top edge by a gap. , The scooping plate rises It is arranged so that it can move freely along the upper edge when it is in an inclined state in which a large number of staples are slid down, and it is further straddled over a large number of staples in a downhill posture toward the guide rail. The thin tip of the extraction claw under the head of the staple is advanced along the ascending slope in the direction opposite to the downhill direction of the staple, and the staple that is seated is extracted and collected on the extraction claw. In addition, the extraction claw is formed so as to be capable of tilting downward toward the inside of the hopper, and the collected staples are returned to the inside of the hopper. 2. A hopper for accommodating a large number of U-shaped staples is provided with a plurality of scooping plates, which are vertically movable through a plurality of juxtaposed slits provided at the bottom of the hopper, By moving the scooping plate above, the stapling in the hopper is scooped up to the upper edge of the scooping plate in a straddle-like manner, and the scooped up stapling is rotated to tilt the upper edge to incline the upper edge. In the stapler supplying device which slides down the rails and supplies the guide rails to the corresponding guide rails in the next stage, the stepper further straddles on a large number of staples aligned and straddling the upper edge of each scooping plate. The corresponding number of extraction claws for extracting each of the above is arranged in the hopper, and each of these extraction claws has a thin tip in the traveling direction, and the tip is in the open state and with respect to the upper edge. U-shaped step With a gap through which one of the heads passes, the scooping plate rises and is placed in an inclined state where it slides down a large number of staples. The slender tip of the extraction claw underneath the head of the steple, which is further straddled over a large number of staplings in the direction of sliding down By advancing it, the staples that are straddled are pulled out and collected on the extraction claws.Furthermore, each of the extraction claws is formed so that it can be tilted downward into the hopper, and To the inside of the hopper, and further, between the plurality of slits in the hopper, a partitioning member having a mountain-shaped cross section for partitioning the upper slits from each other is provided in a rising shape and Of the partition member Aspect, staple supply device, characterized in that the staple are the inclined wall so as to guide upward of each slit.
