Description

    The present invention relates to a linear object assembly binding apparatus that bundles soft linear objects such as pasta, raw noodles, incense sticks, and wires into a bundle of a predetermined weight and number (accumulated as an aggregate) and bound with a binding tape. .

  The present applicant has proposed this type of binding device as Japanese Patent Application No. 2015-99565. This is because the stack is intermittently transported by placing it on the transport bucket, and the stack is pushed up to the center position of the chuck of the bundling part provided above the transport bucket by the lifting bucket at the stopped position. It is gripped and rotated, and a binding tape is wound around the outer periphery to bind them. In this case, even if there is a slight difference between the inner diameter of the chuck and the outer diameter of the assembly (in order to prevent breakage, the inner diameter of the chuck is slightly larger), the binding tape can be wound with an appropriate tightening force. It is what I did. Specifically, since the binding tape was sandwiched between two needles and wound around the assembly, the needle pulled the binding tape and bound it with an appropriate tightening force if there was a slight difference in diameter.

On the other hand, there was some kind of time loss in the supply, bundling and discharging of the aggregates, which extended the working time. In other words, the stacked body placed on the transport bucket is rolled up by the lifting bucket and pushed up to the center position of the chuck, this is gripped by the chuck body and rotated, and the binding tape is wound around to form a binding object. This means that the transport bucket cannot be moved unless it returns to the transport bucket at the position. (If the transport bucket is moved during this time, another stack is placed on the transport bucket that has moved. There is no longer a position to lower the body). Further, since the push-up bucket enters the inside of the chuck, the chuck cannot be rotated unless it is lowered outside the rotation locus of the chuck.

Therefore, after scooping up the accumulation body with the lifting bucket from the conveying bucket, raising it upward and passing it to the chuck, lowering the lifting bucket from the rotation locus of the chuck, rotating the chuck and winding the binding tape to make a bundle, The push-up bucket must be raised again to receive the bundle and placed on the transport bucket at the same position as before. In other words, the structure is such that the transport bucket cannot be moved unless one push-up bucket takes a cycle of ascending, descending, waiting, ascending and descending. In view of this, the present invention aims at shortening the working time by supplying the stacked body to the chuck and discharging the bundle from the chuck by separate members so that they can be operated simultaneously.

Under the above-mentioned problems, the present invention intermittently conveys a predetermined amount of a linear object accumulation body using a conveyance bucket, and chucks the accumulation body with a lifting bucket on a bundling portion provided in the middle. , Grip the both ends with chucks coming out from both sides in the width direction of the transport bucket, lower the push-up bucket and rotate the chuck, and at the same time wrap the bundling tape around the outer circumference to bind the push-up bucket In the linear object stacking apparatus that re-raises and opens the chuck to receive the bound object, and lowers it again to move it to the original conveying bucket and resumes conveying. A slide hopper that moves back and forth is provided on the non-carrying side. After bundling and transporting the bucket, the slide hopper is moved to the non-carrying side to receive the bundle. That other is obtained by providing a linear material aggregate bundling device and returning to the original conveying bucket cohesion was to move the conveying bucket to 1 pitch feed side.

By taking the above-described means, the chuck may be rotated if the push-up bucket moves down the accumulated body to the chuck. On the other hand, since the bundle is received by a slide hopper that does not interfere with the movement of the push-up bucket or the transport bucket, it can be quickly bound, and the push-up bucket also transfers the stack to the chuck. You can move it later. As a result, the working time is shortened, but this time is shortened by 20 to 30% according to the inventor's measurement.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of the bundling device, and FIG. 2 is a plan view, but two rows of transport buckets 1 moving from the forward side in the transport direction to the backward side (hereinafter sometimes referred to as the transport side or the counter-transport side). Is provided. A bundling portion 3 is provided in the middle of the conveyance device 2, and the bundling portion 3 is provided above the conveyance device 2. The bundling is performed by supplying a bundling tape (hereinafter referred to as a tape) 4 stored in a tape case 5 provided on the upper side to a stack 8 held by a chuck 7 by a tape feeding device 6.

3 to 8 are side views of the main part showing the configuration of the bundling part 3, and FIGS. 15 to 19 are plan views showing the main part of the operation of the bundling part 3. The chuck 7 of this example is an integrated body 8. Each chuck body 9 is provided at the tip of an arm 13 pivotally attached by a pin 12 to a base 11 fixed to a frame 10 of a bundling portion 3. The tail 14 of the arm 13 is in sliding contact with the conical surface of the conical cone 15 provided on the frame 10. The same set of chucks 7 is provided opposite to both sides of the conveying device 2, and the conical cone 15 can be inserted into and removed from the frame 10 in the width direction of the conveying device 2. Is getting bigger

By the way, since there are many similar figures including the above-mentioned drawings, the reference numerals will be included in the first drawing in the following, and in the second and subsequent sheets, the same members may be omitted. However, it may be included as needed when important members or new explanations are required or when different movements are required.

A groove 16 is formed in the circumferential direction on the shaft outside the large diameter portion of the cone cone 15, and a roller 17 is fitted in the groove 16. The roller 17 is centered on the pin 18 in the width direction of the transport bucket 1. It is provided at the tip of the bar 19 that swings. Further, the bar 19 is linked to an actuator 20 attached to the frame 10, and by operating this, the chuck cone 9 can be opened and closed by moving the conical cone 15 in and out. The opening degree and the initial opening degree can be adjusted. This is to cope with a difference in outer diameter of the aggregate 8.

Since the center of the chuck 7 is above the conveying bucket 1, when the stack 8 is gripped by the chuck body 9, the center of the stack 8 must be raised to that position. Therefore, push-up buckets 21 that can be raised and lowered are provided in two rows on the outside of the transport bucket 1, and the stacked body 8 transported by the transport bucket 1 is scooped up and pushed up to the vicinity of the center position of the chuck 7. Next, the bar 19 is swung out, the chuck body 9 is tightened, and the integrated body 8 is gripped. In this state, the push-up bucket 21 is lowered because it has no use. At this time, as an example in which the movement is restricted, there is a possibility that the stack 8 is folded when the stack 8 is placed with overlapping heights of the transport bucket 1 and the lifting bucket 21. I can't move it. Of course, the chuck 7 cannot be rotated unless the lifting bucket 21 is lowered outside the rotation locus of the chuck 7.

Further, although not shown in the drawing, in order to wind the tape 4 from one side of the chuck body 9 around the outer periphery of the stack 8, one needle protrudes from the upper surface side of the tape 4 and comes into contact with the surface of the tape 4. Plug in. The reason is that the tape 4 is fixed and wound around the assembly 8 without loosening. As a result, the tape 4 is smoothly pulled out from the tape case 5 via the tape feeding device 6 and wound around the assembly 8 with an appropriate tightening force. It is done. Since this tape 4 is a material that has elasticity and can be heat-welded, it is possible to further strengthen the winding force. As another tape material, paper and a material that can be thermally welded to the back surface thereof are coated, sprayed, or laminated and laminated, and this also enables thermal welding with a strong clamping force. When the tape 4 is wound by a predetermined amount, it is cut by heat sealing with the heater and cutter unit 2. Thereafter, the needle that has fixed the tape 4 to the assembly 8 is moved back to the original position.

In the present invention, two rows of bar-shaped slide hoppers 23 extending in the transport direction are provided outside the transport device 2 below the chuck 7, and the slide hoppers 23 are transported by one pitch of the transport bucket 1 by an appropriate mechanism. And reciprocate to the opposite side. The slide hopper 23 is set so as not to interfere with members such as the conveying bucket 1, the chuck 9, and the lifting bucket 21 in terms of height and plane, and can be moved at any time.

3 to 8, the stacked body 8 placed on the transport bucket 1 is lifted up to the vicinity of the center of the chuck 7 by the lifting bucket 21 and the chuck body 9 is tightened. Tape 4 is wound to change the aggregate 8 into a bundle 24. During this time, the transport bucket 1 is moved to the one-pitch transport side, but in this case, the chuck body 9 cannot be opened and the bundled object 24 cannot be placed on the transport bucket 1 underneath (the other stack 8 is Because it is listed). Therefore, two openers 26 that rotate downward around the pin 25 are provided at the lower position of the chuck 7 when the slide hopper 23 moves to the non-conveying side, and after the binding, the chuck body 9 is opened and the binding object 24 is opened. When the two are opened, the two openers 26 are closed and received once. Then, if the opener 26 is opened when the slide hopper 23 is moved to the conveying side by one pitch, the bundle 24 falls to the empty conveying bucket 1 at the original position.

FIG. 20 is a time chart showing the above movement. In the present invention, the transport bucket 1 is moved to the transport side as soon as the push-up bucket 21 is lowered. On the other hand, the chuck 7 can be rotated (bundled) when the lifting bucket 21 is lowered to a position where the stacked body 8 is supplied to the chuck body 9 and the chucking body 9 is lifted. If you move down, you can move. In addition, the transport bucket 1 and the slide hopper 23 can move independently of each other. For this reason, time loss is remarkably reduced. Each member must be moved at the specific timing described above, but may be moved in each sequence using a known cam or cylinder as a drive source.

9 to 14 are explanatory diagrams of a process of determining whether the bundled body 24 is bundled to form the bundled object 24. The outline of the process is as follows. A temporary bucket 30 including a weight determination unit 28 and a binding state determination unit 29 is provided for the object 24 via a first relay bucket (1) 27. On the other hand, a second relay bucket (2) 31 is provided on the downstream side, and a chute 32 is provided further downstream thereof. A pole 33 that extends close to the chute 32 and extends obliquely upward is provided, and a non-defective product discharge bucket 34 is provided so as to be able to rise.

With the above configuration, when the weight determination unit 28 and the binding state determination unit 29 determine that the binding object 24 is a non-defective product, the non-defective product in the temporary bucket 30 is transferred to the non-defective product discharge bucket 34 through the second relay bucket (2) 31 and the chute 32. Take out above the chute 32. On the other hand, if it is determined as a rejected product, the chute 32 moves to create a gap between the pole 33 and the bundle 24 is discharged downward.
