First to third nozzles 17, 18, 19
As shown in FIGS. 1 and 3, each is a cylindrical body having the same shape, and is parallel to each other at a predetermined same interval, and is substantially upward along the substantially center of the sliding surface of the inclined main body 23. , A first nozzle 17, a second nozzle 18, and a third nozzle 19 are provided on the inclined chute 15 via a nozzle mounting portion (not shown) in this order. And these first to third
As shown in FIG. 1, the nozzles 17, 18, and 19 are substantially opposite to the rear surface 20 a facing the inclined main body portion 23 of the bagged product 20 held by the holding portion 16 and the inclined main body portion 23. It is arranged so that air can be blown vertically. Therefore, the first nozzle 17 can blow the blown air onto the upper part of the rear side surface 20a of the bagged product 20 held on the holding unit 16, and the second nozzle 18 can blow the blown air. Can be sprayed on the approximate center of the rear side surface 20a of the bagged product 20,
The third nozzle 19 blows the blown air to a lower portion of the rear side surface 20a of the bagged product 20. As shown in FIG. 3, the inclined main body 23 is provided with a vertically long rectangular opening 31, through which the first to third nozzles 17, 18, and 19 blow out. Air (pressure air) is blown against the bagged product 20. Further, the first to third nozzles 1
7, 18, and 19 are such that these tips are inclined chutes 15
In order not to come into contact with the bagged product 20 that slides down, each tip is arranged so as to be behind the sliding surface of the inclined chute 15.

The first to third nozzles 17, 1
8 and 19, as shown in FIG.
2, 32, 32 are connected. Each air supply pipe 32 is connected to a supply source (not shown) of pressurized air via first to third solenoid valves (not shown) connected thereto.
Each of these three solenoid valves is provided at a predetermined time interval, for example, at a predetermined time interval, when an article detector 33 described later detects the bagged product 20.
The control unit (not shown) controls the first to third solenoid valves to open and close in order of two seconds. The control unit controls the opening and closing of each solenoid valve according to a predetermined program stored in the storage unit in advance. However, the first to third nozzles 17, 18, 19
The time interval at which the compressed air is blown out from the bagged product 20 is set so that the bagged product 20 can be reliably pushed down to the front side.
Time interval appropriate for the length, width, weight, pressure air blowing amount, number of nozzles, etc., for example, 0.1 to 0.3
Must be set to seconds.

The article detector 33 is a reflection-type photo sensor, and is connected to the control unit. This article detector 3
3, when the bagged product 20 is supplied to the inclined chute 15 and slides down, as shown in FIG. 1, when the bagged product 20 is held on the holding unit 16, the bagged product 20 is detected and detected. A signal is generated, and this detection signal is output to the control unit. When the control unit receives the detection signal from the article detector 33, the control unit sequentially opens and closes the first to third solenoid valves in this order at intervals of, for example, 0.2 seconds. As a result, compressed air is blown out of the first to third nozzles 17, 18, and 19 at the predetermined time intervals in this order.

According to the forward moving device 14 of the article constructed as described above, as shown by a two-dot chain line in FIG.
5, and slides down on the inclined chute 15 to be held on the holding portion 16, the article detector 33 detects the bagged product 20 and generates a detection signal. Then, the control unit controls the first to third nozzles 1
Pressurized air can be sequentially blown out at predetermined time intervals from 7, 18, and 19, and the air blown out from each of the nozzles 17, 18, and 19 is parallel to the longitudinal direction of the rear side surface 20a of the bagged product 20. On the center line, the upper part of the bagged product 20 (where the distance from the upper end 20c is relatively short), the center part (where the distance from the upper end 20c is longer than the upper part), and the lower part (the upper end) 20c) can be sprayed one after another in this order. Thus, the bagged product 20 can be rotated forward (counterclockwise in FIG. 1) around the lower end 20d as a fulcrum without moving the lower end 20d of the bagged product forward. 20 to the vertical seal portion 20e
Can be dropped on the feed-out conveyor 21 such that the back surface (the front side surface 20b) on which the is formed is downward.

Here, the first to third nozzles 17, 1
The reason why the compressed air is sequentially blown out in this order at predetermined time intervals from 8, 19 will be described. By blowing air from the first nozzle 17 disposed at the uppermost position, for example, on the rear side surface 20a of the bagged product 20 on the inclined chute 15, the bagged product 20 is removed from its lower end 20d. Considering the case where the bag is pushed out to the front side with the fulcrum as a fulcrum, if the air blowing force is weak, the bagged product 20 at this inclined position can be pushed out slightly forward with the lower end portion 20d as a fulcrum, May return to the inclined position.
If the air blowing force is too strong, the lower end portion 20d of the bagged product 20 may also move to the front side, and the bagged product 20 may not be pushed down to the front side and may fall to the rear side. is there. At this time, the back surface 20b on which the vertical seal portion 20e of the bagged product 20 is formed faces upward,
In some cases, the bagged product 20 cannot be suctioned by the suction unit.

Therefore, according to the article forward device 14 according to this embodiment, first, the compressed air is blown out from the first nozzle 17 to blow air to the upper part of the rear side surface 20a of the bagged product 20. . Thereby, bagged goods 2
0 can be slightly pushed forward with its lower end 20d as a fulcrum. Here, as the bagged product 20 is pushed slightly forward, the distance between the tip of the first nozzle 17 and the rear side surface 20a of the bagged product 20 becomes longer. The force for pushing the bagged product 20 to the front side is weakened. However, in this state, the second part for blowing air to the central part and the lower part of
And the tip of each of the third nozzles 18 and 19 and the bagged product 20
Since the distance from the rear side surface 20a is relatively short, the compressed air is sequentially blown from the second and third nozzles 18 and 19 to push the bagged product 20 with its lower end portion 20d as a fulcrum. From the closed position, thereby ensuring that the bagged product 20 can be pushed forward.
It can be tilted down while rotating forward so that b is down.

The first to third nozzles 17, 1
Reference numerals 8 and 19 denote predetermined positions on the rear side surface 20a of the bagged product 20 to which the compressed air is blown, that is, positions opposed to the upper portion, the central portion, and the lower portion. Since it is provided so as to be substantially perpendicular to the surface of each corresponding position of 20, the energy of the compressed air blown out for pushing down the bagged product 20 to the front side can be used efficiently.

FIG. 1 shows the upper end portion 20 of the bag 20.
c to the lower end 20d (hereinafter referred to as “bagged product 20”).
Length. " ) Supplies a relatively long bagged product 20 to the forwarder 14 for this article, FIG.
An example is shown in which a bagged product 30 having a relatively short length is supplied to the forward moving device 14 for this product. As shown in FIG. 1, the compressed air sequentially blown out of the first to third nozzles 17, 18, and 19 is applied to the bagged product 20 having a relatively long length as described above. 20
The bagged product 20 can be pushed down by spraying sequentially on the rear side surface 20a. Then, as shown in FIG. 2, for the bagged product 30 whose length is relatively short, the holding unit 1
6, two nozzles located closer to 6, ie the second
And the pressurized air blown out from the third nozzles 18 and 19 in this order can be sequentially blown to the upper and lower portions of the rear side surface 30a of the bagged product 30 to push the bagged product 30 forward.

Thus, as shown in FIGS. 1 and 2,
Even if the bagged product supplied to the forward moving device 14 of the article is changed from a relatively long one at the upper end and the lower end to a shorter one, the holding part 16 and the first to the first to the fourth parts are not changed. It is not necessary to change the mounting position of each of the third nozzles 17, 18, and 19, and the relatively short bagged product 30 conveyed by the inclined chute 15 and held by the holding portion 16 can be reliably moved to the front side. Can be pushed down. In this way, even when the length from the upper end to the lower end of the bagged item is changed from a relatively long one to a short one, and even if the length is changed from a relatively short one to a long one, the holding part 16,
In addition, since it is not necessary to change the mounting position of each of the nozzles 17, 18, and 19, it is possible to save labor and time for this.

The first to third nozzles 17, 1
The nozzle mounting portions (not shown) for mounting the nozzles 8 and 19 to the inclined chute 15 include first to third nozzles 17 and 1, respectively.
8 and 19 can be individually moved in parallel in a direction parallel to the inclination direction of the inclined chute 15 (the sliding direction of the bagged product 20), and can be fixed at a desired position. Therefore, according to the length of the bagged product 20 supplied to the inclined chute 15, two of the first to third nozzles are used.
By the pressure air blown out from the above desired nozzle,
The positions of the first to third nozzles 17, 18, and 19 can be adjusted so that the bagged product 20 can be reliably pushed down to the front side. As shown in FIG. 3, the left and right side walls 25 and 26 are fixed at their upper ends to the left and right ends of the mounting portion 24 by bolts 34 and nuts 35 via spacers 29 and 29. I have. Therefore, when a relatively narrow bagged product 30 is supplied to the inclined chute 15, when the packaged product 30 is supplied to the inclined chute 15, it can be guided to a substantially central position of the holding unit 16. Thus, the spacers 29, 29 are removed and the left and right side walls 25, 26 are attached to the mounting portion 2.
4 can be fixed and attached to each of the left and right ends with bolts 34 and nuts 35.

Further, as shown in FIG.
When detecting the bagged product 20 (or 30) held by the holding unit 16, the first to third nozzles 1
7, 18, 19 (or the first and second nozzles 18, 1
From 9), pressurized air is supplied in this order from the bag 20 (or 3).
0) can be sequentially blown to the predetermined locations, so that the bagged product 20 (or 3) held in the holding section 16 can be sprayed.
In order to push down 0) to the front side, pressurized air can be blown from each nozzle 17, 18, 19 (or 18, 19) at an appropriate timing. Therefore, the bagged product 20 (or 30) is reliably pushed out to the front side and sent out from the conveyor 21.
It can be pushed forward and wasteful use of the blowing air can be avoided. When the bagged product 30 is supplied to the inclined chute 15, the first to third nozzles 17, 18, and 19 are configured to blow out the compressed air. By changing, it is possible to prevent the compressed air from being blown out from the first nozzle 17.

In the above embodiment, the first to third nozzles 17, 18, and 19 are provided. However, instead of this, two or more nozzles other than three are provided. It may be. In short, by using two or more nozzles, pressurized air is sequentially blown from the upper part to the lower part of the bagged product 20 (or 30), and the lower end portion 20d (or 30) of the bagged product 20 (or 30) is blown. With the fulcrum at 30d), the bagged product 20 may be rotated forward and pushed down.

[0030]

According to the first aspect of the present invention, on the rear side of the article held by the holding section, from a predetermined location where the distance from the upper end of the article is relatively short to a predetermined location where the distance is relatively long. Since the gas is sequentially blown to each of the plurality of locations in that order, the article can be turned over while reliably rotating forward with the lower end portion as a fulcrum.
FIG. 5A shows an apparatus for moving articles forward according to the present invention.
To be used when sucking an article which is a bagged product 20 shown in (1) by the suction unit and moving the suction unit to lift the bagged product sucked to the suction unit and packing it in a predetermined outer box. Can be. However, some of the bagged products 20 have a vertical seal portion 20e formed on the rear side surface. Even if the suction portion is pressed against the vertical seal portion 20e from above, the bagged product 20 is surely adsorbed. May not be able to lift. Therefore, the article is securely turned over in a predetermined direction by the article forward device according to the present invention so that the vertical seal section 20e is surely on the lower side, whereby the vertical seal section 20e of the bagged product is formed. The sucked portion surely adsorbs the non-existing surface, lifts the bagged product 20, and ensures that the bagged product 20 can be packed in a box.

According to the second invention, a plurality of nozzles are
Since the blown gas is provided at a position facing each predetermined location of the article to which the gas is blown and is substantially perpendicular to the surface of the corresponding location of the article, the article is pushed down to the front side. Therefore, the energy of the gas blown out can be used efficiently.

According to the third aspect of the present invention, when the length of the article from the upper end to the lower end is changed from a relatively long one to a shorter one, Even when the length is changed from a relatively short one to a longer one, there is no need to change the mounting position of the holding part and the plurality of nozzles, and the comparison is carried by the inclined chute and held by the holding part. An article having a long target length or an article having a relatively short length can be reliably pushed down to the front side. Therefore, the labor and time for changing the mounting position of the holding portion and each nozzle can be omitted.

According to the fourth aspect, when the article detector detects the article held by the holding section, the gas is sequentially blown from the plurality of nozzles to each predetermined portion of the article in a predetermined order. Therefore, gas can be blown out from each nozzle at an appropriate timing in order to push down the article held by the holding section to the front side. Therefore, the article can be reliably pushed down to the front side, and useless use of the blown gas can be avoided.
