Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a rice cracker laver pasting device for surely sticking laver pieces onto a flat rice cracker.

(Prior art) Conventionally, since rice cake pieces with seaweed are pasted by hand, seaweed pieces have been pasted by applying an adhesive such as starch to the rice cracker with a brush, but it is not possible to apply thinly and evenly. Requires skill,
It was complicated and the improvement was desired. Therefore, the applicant of the present application proposed a device for attaching an adhesive to a piece of seaweed and attaching it to a flat rice cracker being conveyed by a conveyor, in Japanese Patent Application No. 63-240179. As shown in FIG. 10, this apparatus feeds a laver piece L, a cutter 2 for cutting to a predetermined size, a laver piece L is conveyed, and an adhesive S having an increased viscosity is applied to the laver piece L. It is comprised of an adding and conveying device 3 for adding to the rice cracker, a carry-in device 4 for the rice cracker M, and an attaching and discharging device 5 for attaching and conveying the seaweed pieces L to the rice cracker M. Then, the procedure of this device is as follows.

The large-sized seaweed pieces supplied from the supply device 1 are cut into a predetermined size by the cutter 2, and the cut pieces of seaweed L are sent to the addition conveying device 3 and the nozzles 6 arranged above them.
The adhesive S having increased viscosity dropped from is adhered and further conveyed by the suction belt 7 to the standby position 8. The seaweed pieces L are attached to the rice cracker M sent by the conveying device 4 by the adhering and carrying-out device 5 over the top and bottom of the rice cracker M and pressed from the outside to squeeze the adhesive S, as shown in FIG. Piece L and rice cracker M were integrated.

(Problems to be solved by the invention) However, when the position of the adhesive S dropped on the seaweed piece L faces the concave portion of the rice cracker M, that is, in the concave portion 9 of the rice cracker M shown in FIG. Since it does not reach and does not act as an adhesive, it is unstablely fixed only at the other adhesive points 10. If many such items are packed in a bag, the seaweed pieces L are likely to be torn and the product value is halved. Further, since the adhesive S to be dropped has a viscosity, it takes time to drop and adhere and dry.

Therefore, there has been a demand for an apparatus that produces a rice cracker with seaweed that is pleasing to the eye and that can be processed quickly.

An object of the present invention is to provide a rice cracker laver pasting device capable of reliably sticking a piece of seaweed to a rice cracker so that the piece of seaweed is not torn when the rice cracker is packed into a bag.

The conveying belt 12 is rotatably provided on the driving roller 13, the tension roller 14 and the roller 15. And is intermittently rotated by the driving means. Further, a dirt wiping roller 16 which is interlocked with the drive roller 13 is installed in contact with the surface of the conveyor belt 12. The surface of the conveyor belt 12 has a plurality of holes 12a (see FIG. 2), and the duct 17 arranged under the conveyor belt 12 communicates with the atmosphere through the hole 10a, and the duct 17 is connected to a suction device. ing. A cylinder 18 is provided on the side of the conveyor belt 12 where the laver pieces L are loaded, and an arm 20 having a suction hole 20a for pulling out the laver pieces L from the supply device 19 is attached to the rod of the cylinder 18. ing. A nozzle for spraying the adhesive S in the form of mist is provided above and in the middle of the conveyor belt 12.
21 is attached to the conveyor belt 12 surface. The second conveyor device is provided on the unloading side of the conveyor belt 12 of the first conveyor device 11.
It is connected to a conveyor belt 23 having a suction hole, which is provided in 22 and has the same structure as the conveyor belt 12, and the conveyor belt 23 is continuously rotated.

The feeding device 19 is rotatably provided with a conveyor belt 25 having pawls 24 engaged with the end portions of the seaweed pieces L at intervals, and is driven intermittently. Reference numeral 26 is a guide plate that supports both sides of the laver piece L, and 27 is a wire hanging so as to come into contact with the passage position of the laver piece L. Further, a cutter 28 for cutting the seaweed pieces L at appropriate intervals is provided with a conveyor belt 12 of the first conveyor device 11.
A holding plate 29, which is installed between the carry-in side and the carry-out side of the conveyor belt 25 of the supply device 19 and which fixes the seaweed piece L in cooperation with the operation of the cutter 28, is vertically movable.

As shown in FIG. 1, the nozzle 21 of the first transfer device 11 is provided on a mounting plate 31 that is screwed to a base 30 above the transfer bell 12 so that the vertical position can be set. It is fixed to the long hole 31a with a screw 32, and the conveyor belt 1
It is designed to jet toward two sides. Further, the nozzle 21 is connected to a pipe 33 for supplying compressed air for injection and a pipe 34 for supplying an adhesive. Both sides of this nozzle 21, that is, a pair of position sensors (detectors) 35, 35 are supported by the universal joint 36 in the front-rear direction with respect to the transport direction, and when stopped,
The presence or absence of seaweed pieces L is detected with respect to the width of the surface of the adhesive S sprayed onto the conveyor belt 12 in a mist form.

Next, the operation will be described. First, all of the rice cracker laver pasting device is activated. When the suction device operates, air is sucked from the hole 12a of the conveyor belt 12 as indicated by an arrow in FIG. 1, so that the seaweed pieces L cut by the cutter 28 are adsorbed to the conveyor belt 12 with an appropriate interval. In this state, it can be intermittently conveyed downward of the nozzle 21. On the way
The wind does not cause misalignment. The position sensor 35 detects whether or not the seaweed pieces L are present below the nozzles 21 while the intermittently rotating conveyor belt 12 is stopped. It is detected whether the front end portion and the rear end portion of the conveyed seaweed L are at predetermined positions, and when the signals of both the pair of position sensors 35, 35 are output, the adhesive S is ejected from the nozzle 21. Is jetted,
The adhesive S is attached only to the surface of the seaweed piece L. After adhering the adhesive S, the seaweed pieces L conveyed at a constant interval are further conveyed and stopped at the conveying end of the conveyor belt 12. Then, at the time of the next rotational movement, the second transfer device 22
To the conveyor belt 23. Nori seaweed L on the conveyor belt 23
Will be conveyed at a constant speed without being stopped and will be wrapped around the rice cracker M by the second conveying device 22. FIG. 3 shows a state in which the seaweed pieces L are wrapped around the rice cracker M.

The pair of position sensors 35, 35 are used when the size of the laver piece L is short such as the length l ₁ of the laver piece L shown in FIG. 5 due to the adjustment when cutting the laver piece L, or as shown in FIG. When the laver pieces L supplied first are cut by the cutter 28 and the laver pieces L supplied are shorter than the predetermined length l ₀ , the pair of position sensors 35, 35 detects either side of the conveyor belt 12. Nori seaweed L
Detection signal is not output, and as a result, the adhesive S
Does not squirt and the conveyor belt 12 does not get dirty. Further, as shown in FIG. 5, when the length l ₂ of the laver pieces L is long due to the adjustment at the time of cutting, it is detected without any problem and the adhesive S is sprayed. At this time, even if there is a piece of seaweed L of length l ₂ , a cutter is used to divide the supplied piece of seaweed L of a certain size into a set number.
Since 26 operates, the seaweed piece L having a length of l ₂ is not further cut. In addition, the seaweed pieces L having a short length are conveyed as they are, and are collected together with the rice cracker M on the discharge side of the second conveying device 22.

FIG. 7 shows another embodiment. This device has nozzles 21 arranged side by side, and the adhesive S is attached to the seaweed pieces L at two places as shown in FIG. 9, and the seaweed is surely adhered to both sides of the flat rice cracker M as shown in FIG. The piece L will be wound. Further, when the size of the seaweed pieces L is changed, as described above, it is standard that the seaweed pieces L stop at the carry-out end of the conveyor belt 12, and the front, rear, upper, and lower positions of the nozzles 21 are adjusted according to this interval. .

As described above, by commercializing a flat rice cracker with seaweed, the seaweed pieces can be attached more reliably than when the adhesive was spotted, the amount of adhesive used was halved, and the alcohol content during adhesion was reduced. Since it evaporates quickly, production efficiency is good. In addition, the seaweed surface at the spotting point was twisted and the product value was low, and it was attached in the form of a fog, and there was no deformation, and
Easy to wrap.

(Effect of the Invention) Since the present invention is configured as described above,
In the transport device of No. 2, the adhesive is surely sprayed onto the adhering surface of the seaweed pieces appropriately sized by the detector, and the transport belt can be kept clean. Further, if the seaweed pieces do not have a sufficient adhesion surface, the pieces are not sprayed, and if they are longer than a predetermined size, they can be set to be sprayed, and the seaweed pieces can be used efficiently. In addition, the adhesive surface with the rice cracker is widened so that it is not affected by the concave surface of the flat rice cracker, and nori pieces stick to the flat rice cracker reliably, and the product value of the flat rice cracker with seaweed increases. It should be noted that it is more economical than attaching adhesive on both sides of the seaweed surface in succession, and eating the edge of the rice cracker does not remove the adhesive surface and peels the seaweed.
