DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shaft-like material supply apparatus for supplying shaft-like materials such as packaged chopsticks in which disposable chopsticks are placed in a sealed bag, one by one to a predetermined position.

[0002]

2. Description of the Related Art At the time of resin film packaging of a lunch box, packing chopsticks are also packed together with the lunch box. Therefore, it is necessary to supply the packing chopsticks to the lunch box immediately before packaging. The part was fixed with adhesive tape. However, the fixing work was performed manually and was very complicated. Further, as a solution to this problem, there has been proposed a supply receiving stand device for simultaneously supplying packaging disposable chopsticks to be packed together with a lunch box to a packaging machine and packaging the lunch dispenser and packaging disposable chopsticks together. (Heisei Kaihei 5-7604).

Means for supplying chopsticks (shafts) one by one to a predetermined location at a predetermined timing for forming chopsticks (shafts) into packaged chopsticks are widely known (Japanese Utility Model Application Laid-open No.
No. 9 801 and Jitsuho 5-31055).

[0004]

When packaging chopsticks (shafts) are packed in a film together with a lunch box, if the chopsticks are not correctly supplied to the transport path of the lunch box, a bento box without packing chopsticks, that is, a defective product Will occur. Therefore, it is necessary to always attach packaging disposable chopsticks to the lunch box, and even if the above-mentioned packaging tray is adopted, accurate supply of the packaging disposable chopsticks to the tray is all done manually, which is a complicated operation. I have.

[0005] Further, even if the conventional disposable chopstick supply device described above is used for automatic dispensing of disposable chopsticks, the conventional disposable chopstick supply mechanism strongly holds the supply objects in an aligned state, and the disposable disposable chopsticks are supplied one by one. It can be applied only to objects that will not be deformed or damaged even if the supplied object is subjected to some external force, and can be applied by external force like packaging chopsticks It cannot be applied to a product whose surface wrapping paper is torn. In view of the above, the present invention proposes an apparatus capable of reliably supplying an inconvenient shaft-like object such as a package disposable chopstick one by one at a predetermined timing.

[0006]

According to the present invention, there is provided an apparatus for feeding a shaft-like material, comprising: a hopper for storing the shaft-like material; and a conveyor belt having a surface on which a mounting ridge for one shaft-like material is projected. A single conveyor mechanism that is inclined from the bottom of the hopper to a predetermined height, and a slip conveyor that is formed continuously from the outlet of the single conveyor mechanism and formed of a material to which the axial supply can slip. Above the above, there are a number of operation stoppers in series in the conveying direction, which are arranged in series in the conveying direction, with a number of operation stoppers for preventing conveyor conveyance of the axial supply by a predetermined operation control, and a predetermined supply point for the axial supply at the outlet of the alignment discharge mechanism. And a supply mechanism for unloading.

Particularly, in the above-described apparatus, a small hole is formed at a predetermined position of the conveyor belt of the single transfer mechanism, and an air suction unit is provided at a position corresponding to the small hole on the back surface of the belt. On the transport surface side, an elimination unit that blows air to the transport surface is attached, and the operating speed of the conveyor belt of the single transport mechanism is sufficiently faster than the supply speed of the supply material required by the supply mechanism. At the same time, perform intermittent operation based on the sensor signal from the aligning and unloading mechanism,
The slip conveyor of the aligning and unloading mechanism is operated at a speed sufficiently higher than the belt conveyor speed of the single transport mechanism, the supply leading end of the series of operation stoppers is matched with the supply timing to perform the stopper release operation, and other operations are performed. Normally, the stopper is set to a state in which the shaft-like object is prevented from moving, and control means is provided for performing an unblocking operation only when the shaft-like object does not exist in the stopper state on the supply side stopper of the stopper. is there.

[0008]

[Action] When a single supply mechanism is operated by storing an axial supply (such as disposable chopsticks) in the hopper, the axial material in the hopper is placed on the mounting ridge and is transported upward by the conveyor belt. but is the so con base Aberuto is inclined, excess axial was dropped, transported in alignment unloading mechanism is transported every 1. In the aligning and transporting mechanism, the feed is performed to the supply mechanism at a predetermined timing by performing the forward feed for each piece by the operation stopper, and the supply mechanism transports and supplies the axial supply to a predetermined supply location.

In particular, if a small hole is formed at a predetermined position of the conveyor belt of the single transfer mechanism, an air suction section is provided on the back of the belt and an exclusion section is provided on the belt front side, the belt is loaded when the belt is unloaded. When a plurality of pieces are placed on the placing ridge, except for the shaft-like material sucked into the small holes, the pieces are dropped by the blowing of the air of the elimination part, and the plurality of pieces are prevented from being supplied.

[0010] The overall supply timing is controlled by aligning and holding the shaft-like object in a slipping state by each operation stopper on the slip conveyor, and releasing the shaft-like object's tip end operation stopper by an unblocking operation (predetermined timing). The feed of each piece is performed, and one feed of the shaft is carried out by the sequential operation of each operation stopper for each supply, and the conveyor belt of the single transport mechanism is operated when the number of aligned and held pieces becomes less than a predetermined value. At least, a predetermined number of pieces are aligned and held again, so that a reliable supply of the shaft-like material at a predetermined timing is realized.

[0011]

Next, an embodiment of the present invention will be described. The shaft-like material supply device shown in the embodiment is the disposable chopstick 01 illustrated in FIG.
Is a device for supplying packaging chopsticks (shaft-like material) a in a packaging bag 02 to a packaging line c of a lunch box b at a predetermined timing, comprising a hopper unit 1, a single transport mechanism unit 2, and an aligning and unloading mechanism unit. 3 and a supply mechanism 4.

The hopper section 1 stores packaging chopsticks a arranged in a certain direction at a width corresponding to the length of the packaging chopsticks a. The single transport mechanism 2 is a conveyor belt (suction conveyor) that is installed at a predetermined height from the bottom of the hopper 1.
The conveyor belt 21 has on its surface projecting ridges 22 for one piece of packaging chopsticks (shafts) a to be conveyed, and locating projections 22 at positions near both sides. A small hole 23 is formed at a position behind the package chopsticks a when the package chopstick a is placed on the strip 22, and an air suction portion 24 corresponding to the small hole is provided on the back surface of the conveying portion of the belt 21. Become. The air suction part 24 is formed by a suction gutter 241 having an opening where the small hole 23 passes, and a suction pipe 242 connecting the suction gutter 241 and a blower (not shown). Further, on the conveying surface side of the suction conveyor 21, an exclusion section 25 for blowing air downward from above the conveying surface is provided, and at the upper discharge position of the suction conveyor 21, packaging chopsticks a
Is attached to a predetermined position (on a slip conveyor of an aligning and carrying-out section described later) so as to be discharged.

The aligning / unloading mechanism 3 is provided with the suction conveyor 2
A slip conveyor 31 made of a material capable of slipping the packaging chopsticks a is provided between the discharge point 1 and the discharge port of the alignment discharge mechanism section (the receiving position of the supply mechanism section 4). ... 32f, 32g for preventing the conveyor chopsticks a from being conveyed by a predetermined operation control.

The supply mechanism 4 comprises a transport conveyor 41 for transporting the wrapped chopsticks to a predetermined supply point, and a drop supply section 42 disposed above the supply point (packing line c). An opening / closing plate 422 connected by a hinge 421 having a biasing ridge, an operation receiving portion 423 protruding from a lower end of the opening / closing plate, and an operation receiving portion 42
An operating body 424 that pushes the opening and closing operation of the opening / closing plate 422 by pushing between the three, and an operating cylinder 425 that operates the operating body.
Consists of

[0015] Thus to package disposable chopsticks a, the apparatus by those supplied every one over lunch b conveyed packaging line c lunch b, the basic operation, stored in the host Tsu par section 1 Then, they are conveyed one by one by the suction conveyor 21 of the single conveying part 2, sent out one by one in synchronization with the line advance (supply timing) of the lunch b by the aligning and discharging part 3, and supplied by the supply mechanism part 4. It falls and is supplied on the lunch box at the timing.
In particular, special feeding means is employed in each mechanism so as to reliably supply one by one to the lunch box a and to prevent supply leakage (production of defective products).

That is, in the single transport mechanism 2, the packing chopsticks a are placed one by one on the placing ridges 22 of the suction conveyor 21, and
That extra packaging disposable chopsticks a in inclination of the suction conveyor 21 is free fall, particularly as in one of the mounting置突Article 22 packaging disposable chopsticks a on two or more are conveyed, packaged are sucked into the small holes 23 chopsticks Objects other than a are forcibly dropped by the blowing of the air from the elimination unit 25, so that one or less packaging chopsticks a are always conveyed to the mounting ridge 22 (see FIG. 6). In addition, the above-mentioned operation is performed several times faster than the supply timing, and the intermittent operation is performed by the signal from the next single transport mechanism 3, and the packaging chopstick a is not placed on the placing ridge 22. Also, the supply of a predetermined number from the single transfer mechanism unit 2 within a predetermined time is ensured.

Next, the operation of the aligning and unloading mechanism 3 is such that the slip conveyor 31 rotates faster than the transporting operation of the single transporting mechanism 2, and the packing chopsticks a are in a slipping state by the blocking operation of each operation stopper 32. The shaft-like object is to be held in alignment.
It is controlled by the operation. That is, the operation of releasing the stop of the front end operation stopper 32a on the line c side (unloading side) is performed by the supply mechanism 4
It operates when it detects that the packaging chopstick a does not exist in the drop supplying section 42 of the present invention, and is substantially synchronized with the supply timing of the packaging chopstick a. Other operating stoppers 32b 32
g, the basic position is the blocking position of the packing chopsticks a, and after detecting that the packing chopsticks a does not exist at the stopper in front of the operation stopper 32, the control is performed such that the blocking release operation is performed with a slight delay. Is what it is.

Accordingly, as illustrated in FIG. 8, on the slip conveyor 31, each of the operation stoppers 32a to 32
g, the packing chopsticks a1 to a7 are blocked in the aligned state (state a) and are on standby. When a predetermined signal (a signal indicating the absence of the packing chopsticks in the falling portion 42) is received, the tip-operating stopper 32a is turned off. The block release operation is performed (state B), and the package chopsticks a1 are supplied to the supply mechanism unit 4. At the same time when the operation stopper 32a returns to the original blocking position, the second operation stopper 32b senses that the packaging chopstick a1 blocked by the operation stopper 32a does not exist, and releases the blocking operation of its own packaging chopstick a2 ( The stopper is raised), and the packaging chopsticks a2 are sent out to the operation stopper 32a. The operation stopper 32b is a front operation stopper 3
When it is confirmed that the package chopstick a2 is blocked in 2a, it returns to the blocked state. Further, when it is detected that the packaging chopstick a2 blocked by the operation stopper 32b does not exist, the next third operation stop 32c releases the blocking and sends the packaging chopstick a3 to the operation stopper 32b which has returned to the blocking position.
The packaging chopsticks a are sequentially forward-forwarded one by one, and the process again shifts to the standby state. Then, the packing chopsticks a2 are sent out sequentially from the operating stopper 32a to the supply mechanism section 4 such that the packing chopsticks a2 are sent out, and the packing chopsticks a are supplied one by one.

When the number of the packaging chopsticks a in the waiting state for alignment is reduced, the rear operating stoppers 32e to 32g become in a state where the packaging chopsticks do not exist at the front stopper position.
It stops at the ascending position (the state of FIG. 9). When such a rising state is sensed, a predetermined signal is sent to the single transport mechanism 2 to operate the same. When the single transport mechanism 2 is operated, the packaging chopsticks a are intermittently supplied one by one to the alignment mechanism section 3. When one packaging chopstick a is supplied, the operation stopper is stopped in the transport of the slip conveyor 31. A packing chopstick a is placed at the position 32d, and a packing chopstick a is placed at the 32d position.
Is detected, 32e shifts to the blocking state and receives the next package chopstick a. When all of the operation stoppers 32 are sequentially brought into the alignment preventing state of the packaging chopsticks a (supply standby state), the operation of the single transport mechanism 2 is stopped.
Therefore, even if the packaging chopsticks a are not placed on the placing ridges 22 in the supply of the single transport mechanism 2, a standby state is formed for each piece by the aligning / unloading mechanism section 3, so that the supply mechanism is provided. Through the part 4, the supply of the packing chopsticks a to the lunch box b before the packing is surely realized.

The packing chopsticks a unloaded from the aligning and unloading mechanism 3 are conveyed by the conveyor 41 to the drop supply unit 42 located above the lunch packaging line c, and are brought into a standby state at the drop supply unit 42, and the lunch box b is moved to the standby state. When the predetermined position is reached, the operation cylinder 425 operates to move the operation body 4 between the operation receiving portions 423.
24, open the opening / closing plate 422, and place
Is dropped on the lunch box b.

According to the present invention, the single operation of the single transport mechanism 2 normally realizes the reliable single supply of the packaging chopsticks a (shaft), but the single transport by the mounting ridge is not necessarily 100%. I can't say for sure. That is, the packaging split chop a may not be placed on the placing ridge. If the supply of one package chopstick a fails, the package lunch itself becomes defective. According to the present invention, the packaging chopsticks are provided by receiving the supply of the packaging chopsticks from the single transport mechanism unit 2 and interposing the sorting and unloading mechanism unit 3 capable of maintaining the alignment standby state in which the supply of the individual packaging chopsticks is performed quickly. This enables a 100% reliable single supply of a.
Of course, the present invention is not limited to the supply device of the package chopsticks as shown in the above-mentioned embodiment, but can be applied to all other shaft-shaped objects.
