BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for a binding machine for automatically transferring an object to be bound which has been carried in by a carry-in conveyor to the binding device.

[0002]

2. Description of the Related Art As a conventional automatic bundling device, for example, an automatic bundling device disclosed in Japanese Patent Laid-Open No. 58-1612 has a plurality of buckets attached to an endless chain, and the objects to be bound in the buckets. It is placed on a predetermined position and conveyed, and a binding head is provided on the upper and lower sides of the conveyance path to automatically bind the objects to be bound placed on the bucket and conveyed by the binding head. is there. And
The material to be bound to the bucket is manually supplied by the worker.

As described above, the binding of the objects to be bound is performed automatically, but the objects to be bound are supplied into the bucket manually by the operator for the following reasons. It was For example, when bundling vegetables or root vegetables (eg asparagus), the vegetables and root vegetables have irregular shapes and are soft and easily scratched, so the fixed idea is that the supply into the bucket must be done manually. In addition, in order to mechanically align such uneven objects to be bound and place them on the bucket, the mechanism becomes complicated and the device becomes expensive. And even now, even if bundling was done manually, it can now be bound automatically, and since the efficiency of bundling work has been further improved, bundling is possible even if it is not automatically fed by expensive equipment. This was because it was considered to be sufficiently satisfactory in terms of work efficiency.

[0004]

However, at the present time when the automatic binding device is used, the awareness is to operate the automatic binding as fast as possible to improve the productivity. As a result, when the automatic binding machine is operated at a high speed, the automatic binding and the supply of the bundled objects into the bucket by manual work, that is, the time balance between the automatic binding and the manual work is lost, and the bucket is transported. When the speed is increased to increase the efficiency of bundling, it is necessary to supply the objects to be bound to the bucket manually accordingly, so that the shape is irregular and soft vegetables and root vegetables are handled. There is a problem that the work of aligning the work and putting it in the bucket becomes rough, and the work is bundled with the work being uneven, and the objects to be bound are scratched.

Further, there is a time limit for manually aligning and putting inconsistent objects to be bound in a bucket so as not to damage them, so that the efficiency of binding cannot be further improved, and a large number of people However, there is a problem that even if the workers are mobilized, the manual work has a time limit and the labor cost is high.

The present invention has been made in view of the above-mentioned circumstances, and automatically arranges the unbalanced objects to be bundled mechanically and prevents the objects to be bundled from being scratched. The present invention is to provide a delivery device for a binding machine that can be supplied in a uniform manner.

EXAMPLE An example of the present invention will be described below. FIG. 1 is a diagram showing the whole of this embodiment, and a delivery conveyor 3 is provided between a carry-in conveyor 1 and a bundling conveyor 2. The delivery conveyor 3 is provided with sprockets 4 and 5 on the carry-in side and the carry-out side, respectively, and an endless chain 6 having a plurality of buckets 7 mounted thereon is hung on the sprockets 4 and 5. Then, by driving the sprocket 5 by the drive device 8, the bucket 7 is moved in the direction of arrow (a). Also,
A hopper device 9 is provided on the carry-in side of the transfer conveyor 3 to transfer the objects to be bound, which have been conveyed by the carry-in conveyor 1, to the bucket 7 of the transfer conveyor 3, and in the middle of the transfer conveyor 3. A bound object shaping device 10 for aligning the bound objects transferred to the bucket 7 is provided. In addition, a robot 11 is provided for transferring an object to be bound in the bucket 7 of the transfer conveyor 3 to the bucket 201 of the binding conveyor 2.

Next, the hopper device 9, the bound object shaping device 10 and the robot 11 in FIG. 1 will be described in detail. First, FIG. 2 is an enlarged view of a portion of the hopper device 9, in which the hopper plates 901 and 902 are the buckets 7.
Are provided so as to face each other in the transport direction (arrow a). The hopper plates 901 and 902 are fixed to a shaft 903, and the hopper plates 901 and 902 are synchronously rotated by a fan gear 907 that gives a rotational force to the shaft 903. The mounting position of the shaft 903 is substantially at the center of the hopper plates 901 and 902.

Further, as shown in FIG. 4, a plurality of buckets 7 are provided at predetermined intervals in the width direction of the transfer conveyor 3, and the hopper plates 901 and 902 are located between the buckets 7 (b). , (C), (D) are provided in a divided state (only the tip portion may be divided), whereby the hopper plates 901 and 902 are provided.
Hopper plates 901 and 90 so that the loci (e) and (f) of the lower end drawn by the rotation of
The lower end of 2 is brought close to the bottom of the bucket 7, and the objects to be bound in the hopper 9 are released in the bucket 7. As a result, the object to be bound is prevented from spilling out of the bucket 7, and the fall distance of the object to be bound into the bucket 7 is shortened to reduce damage to the object to be bound. In this way, by preventing the bucket 7 from spilling out and preventing the objects to be bound from being damaged, the automatic binding machine can be operated at high speed.

Further, as shown in FIG. 2, a hopper plate
The lower end of the hopper plate 902 'is in the bucket 7 so that the objects W to be bound in the bucket 7 can pass in the direction of arrow (a) when the 902 is rotated to the position 902' of the imaginary line. It must be above the upper surface of the object to be bound W. Further, since the hopper plate 901 side is the rear side with respect to the conveyance direction (a) of the objects W to be bound, the hopper plate 901 when the hopper plate 901 is rotated to the position of the virtual line 901 '. The lower end of ′ is the object to be bound W in the bucket 7.
Even if it is below the upper surface of the binding object W, it does not interfere with the conveyance of the objects W to be bound.

From this, as shown in FIG. 2, when the hopper plates 901 and 902 are closed, the hopper plate 9
The lower end of 01 is long and draws a locus (e), and when the objects W to be bound are dropped into the bucket 7 by rotating the hopper plates 901 and 902, the lower end of the hopper plate 901 The object W to be bound is guided to near the bottom of the bucket 7, and the fall distance of the object W to be bound is shortened to minimize damage to the object W to be bound.

Further, the hopper plate 901 is attached by the shaft 903.
And by supporting approximately the middle of 902, shaft 903
Hopper plates 901 and 9 that rotate about
The radius of curvature of the loci (f) and (e) drawn by the tip of 02 is reduced, and the distance H1 from the upper surface of the object W to be bound to the shaft 903 is reduced to downsize the hopper 9.

Also, the hopper plate 901 is attached by the shaft 903.
And 902 supporting approximately the middle portion of the hoppers causes the hopper plates 901 and 902 to pivot to 901 'and 902'.
When the position of the imaginary line is reached, the distance X between the hopper plates 901 ′ and 902 ′ is made substantially the same as the width of the bucket 7, and the lower ends of the hopper plates 901 ′ and 902 ′ are positioned inside the bucket 7. From the hopper plate
901 'and 902' form a kind of vertical guide wall with respect to the bucket 7, and the objects to be bound W from the hopper 9 into the bucket 7.
When transferring the object, the object to be bound W is prevented from spilling out, and the object to be bound W is transferred to the hopper plates 901 and 9
The objects W to be bound are dropped vertically while being gathered at 02 to reduce the rubbing between the objects W to be bound and the hopper plates 901 and 902 and prevent the objects W to be bound from being damaged. In the above embodiment, the hopper plate 902 is 902 '.
Although the lower end of the hopper is made to substantially coincide with the upper surface of the objects W to be bound when rotated to the position, the height of H1 is lowered to rotate to the outside of the side plate 703 of the bucket 7, The plate 902 may be rotated until the lower end of the plate 902 is located above the upper surface of the objects W to be bound.

A hopper body 904 is provided on top of the hopper plates 901 and 902.
And 902 form an inclined surface identical to the inclined surface formed in the closed state. A guide portion 905 having a radius of curvature centering on the shaft 903 is provided above the hopper plates 901 and 902. And the hopper plate 90
When the 1 and 902 rotate about the axis 903 to the vertical positions 901 ′ and 902 ′ as shown by an imaginary line, the guide portion 905 lowers the lower end 9 of the hopper body 904.
The gap with 06 is blocked to prevent the object W to be bound from spilling out of the hopper 9. Then, when the hopper plates 901 and 902 are rotated to their original positions indicated by the solid line with the object W to be bound on the guide portion 905,
The bundled object W is pushed by the lower end 906 of the hopper body 904 and returned to the inside of the hopper formed by the hopper plates 901 and 902.

The mounting position of the hopper 9 shown in FIG. 2 is a portion where the bucket 7 is located on the transfer surface of the transfer conveyor 3 and the bucket 7 is vertical. On the other hand, the mounting position of the hopper 9 shown in FIG. 3 is the position immediately before the bucket 7 passes through the sprocket 4 provided on the carry-in side of the transfer conveyor 3 and moves to the transfer surface of the transfer conveyor 3. At this position, the substrate of the bucket 7 is bent by the radius of curvature of the outer circumference of the sprocket 4, and the bucket 7 is in an open state. Since the bucket 7 is in the open state in this way, it is easy to load the article W to be bound into the bucket 7.

Further, in the embodiment shown here, the lower end 906 of the hopper main body 904 is located in the upper part of the closed hopper plates 901 and 902 as shown in (A), and as shown in (B). The lower side of the lower end 906 has an inclined surface inclined at an angle equal to the inclined surfaces of the closed hopper plates 901 and 902. Therefore, the hopper main body 904 is attached to the bucket 7 shown in FIG. 4 so that the hopper plates 901 and 902 can rotate about the shaft 903.
Similarly to the above, the transfer conveyors 3 are provided at intervals in the width direction. Since other parts are the same as those of the hopper 9 shown in FIG. 2, the same parts are designated by the same reference numerals and the description thereof will be omitted.

Further, as shown in FIG. 3, the hopper 9 shown in FIGS. 2 and 3 is framed by a hopper stand 12.
It is attached to 14. A lever 15 is fixed to the shaft 903, and an end portion of the lever 15 and a rod of the cylinder 13 are connected by a pin 16, so that the cylinder 13 causes the shaft 903 to move.
The hopper plates 901 and 902 are rotated synchronously via the fan gear 907 (see FIG. 2).

Next, as shown in FIG. 2, in the carry-in conveyor 1, an endless belt 102 is hung on a sprocket 103, and the surface of the endless belt 102 is covered with a scraper 101 made of a soft material (for example, a sponge-like material). The bundles W are provided at intervals necessary to hold the bundle W and prevent the bundle W to be fed into the carry-in conveyor 1 from being damaged. Further, this scraper 101 is divided into a plurality of pieces, and when passing through the sprocket 103, the divided scraper 101 is separated as shown in the drawing, and the scraper 101 is separated.
The open ends of the spaces between the members are widened so that the objects to be bound W held in the spaces easily drop from the spaces.

Next, the bucket 7 will be described. Figure 2
And in FIG. 4, the bucket 7 is attached to the chain 6 as follows. That is, a mounting substrate 603 is attached to the chain 6 via a mounting member 601 with bolts 602, while the bucket 7 is attached to the substrate 701 with screws 702. And
The edge of this board 701 and the edge of the mounting board 603 are hinged.
Combined at 17. A spacer 604 is attached to the other end of the mounting substrate 603. And
A locking member 18 is further attached to the other end of the mounting substrate 603. The locking member 18 includes a spring portion 181, a locking portion 182.
And the claw 183, and the spring 181 is screw 1
Attached to the other end of the mounting board 603 at 84
Reference numeral 182 denotes a substrate 701 and a mounting substrate 603, which are in close contact with each other with a spacer 604 interposed therebetween, and engage with the end surface of the substrate 701. The rod head 191 of the unlocking cylinder 19 is attached to the frame 14 by the bracket 20 so as to face the claw 183. Further, a shaping plate 704 is attached to an end portion of the substrate 701 joined by the hinge 17, and the side surface of the bucket 7 attached to the end portion is closed. In addition, a soft protective material 704 such as a sponge is attached to the side plate 703 of the bucket 7 so that the object W to be bound is not scratched.

In FIG. 5A, the locking portion 182 is engaged with the end portion of the substrate 603, and one end of the substrate 701 is joined by the hinge 17.
The mounting board 603 and the mounting board 603 are integrated by the engagement of the locking portion 182. This prevents the base 701 from opening from the mounting base 603 when the bucket 7 moves in the arrow (a) direction, passes through the sprocket 5 and returns to the sprocket 4 side. Then, as shown in FIG. 5B, by pushing the claw 183 with the rod head 191 of the lock release cylinder 19, the spring portion 181 is elastically deformed and the lock portion 182.
Board away from the edge of board 701, board 701
The hinge 17 can be opened with respect to 03. Also, when the rod head 191 is retracted, the elastic force of the elastically deformed spring portion 181 restores the original state, and the locking portion 182 engages with the end portion of the substrate 701.

Next, the bound object shaping device 10 will be described with reference to FIGS. 6 to 9. As shown in FIG.
An engaging portion 703 is formed on a side portion of a joint end by the hinge 17 so as to project. As shown in FIGS. 6 and 7,
Rods are attached to support members 1013 and 1014 that are erected on the base 1001.
A base plate fixed to the slider 1011, which supports the rod 1012 and is provided with a slider (or cylinder) 1011 on the rod 1012.
A bearing member 1002 is attached to 1015. And
A belt 1007 is hung on sprockets 1005 and 1006 fixed to shafts 1003 and 1004 which are pivotally supported on the bearing member 1002, and rotation of a motor 1008 attached to a base plate 1015 is performed via the sprocket 1005 and the belt 1007. Is transmitted to the sprocket 1006. And
The rotor 10 is attached to the shaft 1004 where the sprocket 1006 is fixed.
09 is fixed and the rotor 1009 is rotated. As a result, the sprockets 1005 and 1006 mounted on the bearing member 1002, the rotor 1009, the motor
The 1008 is integrated and is moved by being guided by a rod 1012 by a slider 1011. Also this rotor
1009 is provided with a groove 1010 into which the engaging portion 703 provided on the substrate 701 shown in FIG. 8 fits.

The base 1010 has an inclined plate shown in FIG.
21 are provided. A soft member 2101 such as a sponge is attached to the inclined surface 2102 of the inclined plate 21 so that the object W to be bound is not damaged. The angle of the inclined surface 2102 of the inclined plate 21 is substantially equal to the inclination angle α of the base plate 701 of the bucket 7 that is tilted with the hinge 17 as the base point.
The release part of the bucket 7 is closed to prevent the bundled object W in the bucket 7 from jumping out of the bucket 7 when the substrate 701 is tilted.

Next, the robot 11 will be described. The reason why the robot 11 is used to transfer the objects to be bound on the delivery conveyor 3 to the binding conveyor 2 is as follows. That is, the bucket 201 provided on the bundling conveyor 2
When the bucket 201 is attached to the substrate 701 as shown in FIG. 4 in the mounting (see FIG. 1), when the binding object W in FIG. 4 is bound with the binding tape, the substrate 701 is also put together with the binding object W. It will be bound with binding tape. Therefore, the mounting substrate of the bucket 201 attached to the bundling conveyor 2 cannot be one substrate in the width direction of the conveyor like the substrate 701 shown in FIG. 4,
The substrate 701 must also be cut at the gaps (b), (c), and (d) in FIG.

On the other hand, in the transfer conveyor 3, when the bucket 7 is tilted as shown in FIG. 9, if the substrate 701 is cut at the gaps (b), (c) and (d),
It becomes impossible to tilt the entire bucket 7 substantially and adjust the posture of the objects W to be bound in the bucket 7. Therefore, as shown in FIG. 9, in order to tilt the entire bucket 7 to adjust the posture of the objects W to be bound, the substrate 701 which is a single plate in the width direction of the transfer conveyor 3 is absolutely necessary, and The robot 11 for transferring the to-be-bound object W on the to-be-conveyed conveyor 2 inevitably maintains the condition of the to-be-to-be-bound object W by the to-be-bound object shaping device 10 provided in the middle of this transfer conveyor 3. Will be needed.

Then, as shown in FIG. 10, the robot arm
A cylinder 1103 swings 1101 around a fulcrum 1102 as a fulcrum, and a cylinder 1104 expands and contracts in the arrow direction. When the cylinder 1103 is operated with the robot arm 1101 extended and the robot arm 1101 is swung, the robot hand 1109 contacts the bucket 7 of the delivery conveyor 3 and damages the robot hand 1109 or the bucket 7. There is a risk. In order to avoid such a situation, the robot 11 is provided with a lock lever 1105, and the tip of the lock lever 1105 is engaged with a pin 1107 provided on the robot arm 1101 to make the robot hand 11
Prevents 01 from stretching, and locks the pin 1107 with a lock lever.
When the tip of 1105 is engaged, limit switch 11
08 is turned off and the cylinder 1103 does not operate. Then, as shown in FIG. 11, the engagement of the tip of the lock lever 1105 and the pin 1107 is released, and the limit switch 1108 is turned on by the lock lever 1105, whereby the cylinder 1103 is operated. Further, a soft member 1110 such as a sponge is attached to the robot hand 1109 so that the bundled object W is not damaged when the bundled object W is gripped.

The operation of the present embodiment constructed as above will be described below. In FIG. 1, a transfer conveyor 3 is provided between the binding conveyor 2 and the carry-in conveyor 1. The transfer conveyor 3 is formed by attaching a plurality of buckets 7 to an endless chain 6, and a substrate 701 on which the buckets 7 are attached. Chain 6 tiltable via hinge 17
Since the substrate 701 is automatically tilted, the to-be-bound object W that has been randomly put into the carry-in conveyor 1 is received in the bucket 7 attached to the endless chain, and the bucket 7 is attached. By automatically tilting the substrate 701, the object to be bound W in the bucket 7
The slidable bucket 7 is slid to automatically adjust the posture of the objects to be bound, and the objects can be conveyed to the binding conveyor 2 side.

That is, in the bundling conveyor 2, if the substrate for attaching the bucket 201 to the chain is a single plate in the width direction of the bundling conveyor 2 as shown in the substrate 701 shown in FIG. Since the substrates are bound together with the bound objects W when the bound objects are bound, the substrates in the binding conveyor 2 must be cut at least at the positions where the bound objects are bound. As described above, when the substrate is cut, the substrate cannot be tilted to adjust the posture of the object W to be bound, and it is considerable when the binding conveyor 2 is equipped with a mechanism for adjusting the posture of the object W to be bound. It has a complicated structure. In this embodiment, the transfer conveyor 3 excluding the bundling function is provided, the substrate 701 of the transfer conveyor 3 is formed as a single plate, the bucket 7 is attached, and the substrate 701 is tilted so that the object W to be bound in the bucket 7 is formed. Since the posture is automatically adjusted and passed to the bundling conveyor 2, the structure is simplified and the posture of the object to be bound is automatically adjusted, and this is transferred to the bundling conveyor 2 for automatic bundling. It becomes possible.

In this way, it is possible to automatically adjust the posture of the objects W to be bound by the transfer conveyor 3, and
Since the hopper 9 for transferring the bundle W to be transferred from the carry-in conveyor 1 to the bucket 7 of the transfer conveyor 3 is provided on the carry-in side of the transfer conveyor 3, the bundle to be bundled randomly introduced into the carry-in conveyor 1 Since the article W can be automatically transferred into the bucket 7 of the delivery conveyor 3 by the hopper 9, and the posture of the article W to be bound in the bucket 7 can be automatically adjusted by the delivery conveyor 3, the carry-in conveyor It is possible to automatically perform the steps from the insertion of the object to be bound W into the unit 1 to the step of adjusting the posture of the object to be bound W.

A robot for transferring the material W to be bound in the bucket 7 of the transfer conveyor 3 to the binding conveyor 2 between the transfer conveyor 3 and the binding conveyor 2.
Since 11 is provided, the transfer between the transfer conveyor 3 in which the substrate 701 can be tilted and the binding conveyor 2 in which the binding target W can be bound is automatically performed, and the binding target W is loaded into the carry-in conveyor 1. Therefore, it is possible to completely automate the processes from the shaping of the objects W to be bound on the transfer conveyor 3 to the automatic binding on the binding conveyor 2.
