Abstract

To prevent binding tape that is wound on the reel and binds collected rod-like articles as an article to be bound from running out and getting short while it is being drawn out.SOLUTION: A tape reel 4 with heat welding binding tape 5 wound thereon is mounted, and the ends of the article to be bound are held by a chuck and rotated. Meanwhile, the binding device draws out the binding tape 5 from the reel and winds it onto the outer periphery of the article to be bound. The binding device has two tape reels 4 on the front and the rear in the transport direction, and a tape sensor 12 that draws the binding tape 5 from each tape reel 4 and meanwhile detects the absence and presence of the binding tape 5 is provided. On the downstream side of the tape sensor 12, the binding tapes 5 are merged and double-layered and pass an adhesion device 14 with a heater. When neither tape sensor 12 operates, only one binding tape 5 passes, and when the tape sensor 12 detects the absence of the binding tape 5, the adhesion device 14 with a heater is operated to bind two binding tapes 5.SELECTED DRAWING: Figure 3

Description

The present invention relates to a binding tape breakage prevention device in a binding device that binds with a binding tape while a bound object in which various rod-shaped objects such as dried noodles, incense sticks, and wires are accumulated is conveyed by a transport bucket.

The applicant proposes this kind of binding device as Japanese Patent Application No. 2015-99565 (Japanese Patent Laid-Open No. 2016-216053). In this method, the bound object is placed on a transport bucket and transported intermittently, and when it reaches a specific stop position (this is the binding position), both ends of the bound object are grasped by a chuck and rotated. In the meantime, the reel-shaped binding tape mounted above the binding position is pulled out and wrapped around the outer circumference of the bound object to bind. Then, after binding, the tape was cut and transported again in the transport bucket. That is, the objects to be bound were bound while being conveyed.

The reel in this case is an annular case having an H-shaped cross section, which means that a binding tape is wound around the reel, but it also includes a case where a reel on which a binding tape is wound in advance is attached. Called a reel. In the past, only one tape reel was attached, so if the binding tape was pulled out, the binding tape would break and had to be replaced with a new tape reel. Therefore, during this period, monitoring is required and it takes time and effort for replacement. Above all, the transport bucket had to be stopped, causing a time loss.

Therefore, in the present invention, two reels are provided, and an adhesive portion is provided in which the binding tapes drawn from the respective reels are joined to form a two-ply stack, and normally only one is passed through, and one binding tape is passed. When it runs out, it adheres to the other binding tape so that the binding tape can be pulled out continuously so that there is no break.

Under the above problems, the present invention is a tape reel in which a predetermined amount of the object to be bound according to claim 1 is intermittently transported by a transport bucket, and a heat-weldable binding tape is wound on a reel above the transport bucket. In a binding device that holds both ends of the bound object with a chuck and rotates it at a specific stop position of the transport bucket, and in the meantime pulls out the binding tape from the reel and winds it around the outer circumference of the bound object to bind it. , Two tape reels are provided in the front and rear of the transport direction, a tape sensor is provided in the middle of pulling out the binding tape from each tape reel to detect the presence or absence of the binding tape, and the binding tapes are merged downstream of the tape sensor to form two layers. Pass through a heater-equipped adhesive, and when neither tape sensor works, pass only one binding tape, and when either tape sensor detects the absence of binding tape, activate the heater-equipped adhesive and two sheets. The present invention provides a binding tape breakage prevention device in a binding device characterized by adhering the binding tape of the above.

By taking the above measures, when the withdrawal of one of the binding tapes is completed, the binding tape is already adhered to the other binding tape. Therefore, although the binding tape is doubled at the seam, it is continuous. It is pulled out and the trouble of replenishing the binding tape can be saved. Therefore, no particular monitoring is required and no time loss occurs. During this time, one of the empty reels may be replenished with a new tape reel. It should be noted that it is an arbitrary choice whether to make the bundled product with the double binding tape a good product or a defective product.

It is a front view of the binding device. It is a top view of the binding device. It is a front view of the main part of the reel part of a binding device. It is a top view of the tape sensor of a bundling device. It is a front view of the main part of the tape bonding part of a binding device.

FIG. 1 is a front view of the bundling device viewed from a direction perpendicular to the transport direction, and FIG. 2 is a plan view, but two rows of transports with attachments for mounting bound objects moving from the upper side to the lower side in the transport direction. It has a transport device 2 composed of a bucket 1. A binding portion 3 is provided at a binding position in the middle of the transport device 2, and the transport bucket 1 is periodically stopped at this position (hence, this position is also referred to as a binding position). For binding, the binding tape (hereinafter referred to as tape) 5 wound on the reel 4 housed in the stand provided above the binding position is pulled out by the tape holder 7 of the tape pulling device 6, and both ends are grasped by the chuck 8. It is performed by wrapping it around the binding object 9.

The present invention prevents the tape 5 from running out and being cut off when the tape 5 is pulled out, and is not a method of pulling out or binding, so these will be briefly described. In bundling and transporting, the point is that the bound object 9 is grasped by the chuck 8 and rotated at the position of the binding portion 3, and the tape 5 is pulled out from the foil 4 and wound around the outer circumference of the bound object 9 in the meantime. In this case, since the transport device 2 moves intermittently, the tape 5 is also intermittently pulled out. At the time of binding, it is difficult to rotate the bound object 9 while it is placed on the transport bucket 1, so the lift 10 is used to lift the bound object 9 (when the bound object 9 is rotated, the lift 10 is lowered).

The present invention prevents the tape 5 from being used up and interrupted when it is pulled out. FIG. 3 is a front view of a main part of the device for that purpose, and two reels 4 are provided in the front-rear direction in the transport direction. That is, the frame 11 for mounting the reel 4 is a T-shaped frame including a horizontal frame 11a extending in the front-rear direction in the transport direction and a vertical frame 11b intersecting the horizontal frame 11a, and the concave frame 11c is combined with the horizontal frame 11a. Specifically, each foil 4 is attached to both ends of the horizontal frame 11a, and a tape 5 or a pre-wound one is attached to the tape 5. Then, a tape sensor 12 that detects the presence or absence of the tape 5 that moves to the portion of the concave frame 12 below each reel 4 is attached.

The tape 5 that has passed through the tape sensor 12 is appropriately turned by an idle roller 13 provided on the frame 11 and passed through a heater-equipped adhesive 13 provided on the vertical frame 11b under the concave frame 11c. Here, the tapes 5 are merged into two layers. The tape 5 that has passed through the heater-equipped adhesive 14 is taken over by the tape holder 7 of the tape pulling device 6. However, only one tape 5 is taken over by the tape holder 7, and the other tape 5 is stopped at the place where the heater-equipped adhesive 14 comes out.

When the tape sensor 12 of the moving tape 5 determines that the tape 5 is absent, the heater-equipped adhesive 14 operates to bond the two tapes together. Then, the tapes 5 are stacked and moved toward the tape pulling device 6. Then, when the original tape 5 is exhausted, the tape 5 is switched to the new tape 5, and thereafter, the tape 5 is used for binding. Since there is some time before the new tape 5 runs out, the tape 5 may be replenished to the original reel 4 during that time. Generally, the tape 5 includes a paper tape in which polyethylene resin or the like is laminated on one side and a poly tape in which polyethylene and polypropylene are composited, but any of them may be used in the present invention. When the tip of the tape 5 is fixed to the object to be bound 9 with the tape holder 7 and the object to be bound 9 is rotated, the tape 5 is wound up and bound. Therefore, when two reels 4 are attached to the front and back, the glued surface and the non-glued surface overlap each other, but since they are heated during bonding, bonding is easily performed.

FIG. 4 is a front view of the tape sensor 11, which is fixed to the concave frame 11c. It includes a guide 15 for guiding the tape 5 and a switch (sensor) 16 for detecting the tape 5 passing through the guide 15. If the tape 5 is present and flowing (moving), the switch 16 does not operate (or does not operate), and therefore the heater-equipped adhesive 14 does not operate, and only one tape 5 flows. Continue. The switch 16 in this case is suitable for something like an optical proximity switch. This is because it does not come into contact with the tape 5 and does not resist its movement.

FIG. 5 is a front view of the heater-equipped adhesive 14, in which (a) is when the heater-equipped adhesive 14 is not operating and (b) is when it is operating, but the opening and closing provided in the vertical frame 11b. It has two possible sensing pieces 16a, 16b, and the tape 5 passes between them. As long as the tape 5 is flowing during this period, the sensing pieces 16a and 16b remain open, the heater-equipped adhesive 14 does not operate, and the tape 5 is not adhered. However, before the tape 5 is interrupted (or as soon as it is interrupted), the tape sensor 12 catches it and emits a signal. Then, the sensing pieces 16a and 16b are closed, and the two tapes 5 are crimped.

Since the heater 17 is provided near the sensing pieces 16a and 16b and the tape 5 is heated,
When the sensing pieces 16a and 16b are closed and the tape 5 is crimped, the tape 5 is adhered. The heater 17 may be heated after the tape sensor 11 emits a signal, but it is better to keep the heater 17 heated at all times for quicker and stronger adhesion. When the two tapes 5 are adhered, both of them are sent to the tape feeding device 6, and during this time, the object to be bound 9 is bound by the two tapes, but the previous tape 5 is exhausted and the next tape 5 is exhausted. Switch to tape 5.
