As shown in FIGS. 4 and 6, the chain conveyor device 28 includes endless chains 30, 30 arranged in two rows on the front and rear sides of the increase die storage chamber 23, a drive mechanism, and a drive source not shown.
The drive mechanism of the chain conveyor device 28 is provided at the front and rear ends of the drive shaft 32 and the drive shaft 32 provided to extend to the front and rear of the die storage chamber 23 at the die insertion opening 24. And a driven shaft 33 provided on the lower end side of the lower wall 23e of the additional die storage chamber 23 so as to extend forward and backward of the additional die storage chamber 23; A sprocket (not shown) and a transmission mechanism (not shown) for transmitting the driving force of a drive source such as a motor to the drive shaft 32 are provided.
That is, the upper end sides of the two rows of endless chains 30, 30 are respectively wound around the sprockets provided at both ends of the drive shaft 32, and the lower ends of the two rows of endless chains 30, 30 are both ends of the driven shaft 33. It is hung on each sprocket provided on the side, and it is hung between the front and back two chains 30 and 30 by rotating the drive shaft 32 and circulatingly moving the front and rear 2 chains 30 and 30 between the top and the bottom. The plurality of die transfer trays 29, 29... Connected so as to circulate between the upper side and the lower side.
A plurality of die transfer trays 29 are provided so as to be aligned along the circulation direction (transport direction F) of the chain 30.

As shown in FIG. 6, the increase die transport tray 29 is provided with connecting portions 36 and 36 respectively on the left and right sides (= front and rear sides of the increase die storage chamber 23) of the front end portion in the transport direction F by the chain conveyor device 28 The connecting portion 36 of the die transfer tray 29 and the side surface of the chain 30 are connected by a connecting shaft 37 so that the transfer tray 29 can move along the transfer direction F. That is, the left and right sides of the increased die transport tray 29 on the front side in the transport direction F are connected to the left and right chains 30, 30 via the connecting shaft 37 and the connecting portion 36, and have the increased die accommodating portion 38 on the rear side in the transport direction F. .
That is, in the die transfer tray 29, the front side in the transport direction F of the chain conveyor device 28 as a conveyor is connected to the left and right chains 30, 30 of the chain conveyor device 28 and the die is expanded in the transport direction F rear side of the chain conveyor device 28. The receiving unit 38 is provided, and the die transfer tray 29 is increased by rotating the transport direction F of the chain conveyor 28 connected to the chain conveyor 28 at the upper reverse position of the chain conveyor 28 as a rotation center. The increase die accommodated in the die accommodation portion 38 is configured to be dropped from the increase die drop port 24 into a drop passage 26 described later.
That is, on the left and right sides of the position on the front side of the intermediate position between the front end (front end) and the rear end in the direction along the conveying direction F of the chain conveyor device 28, Are connected to the left and right chains 30, 30. In addition, it is preferable that the front end (tip end) side of the increase die transport tray 29 be connected to the left and right chains 30, 30.
The shape of the increase die accommodation portion 38 is a cross section long in the front-rear direction of the increase die accommodation chamber 23 (the left-right direction with respect to the conveying direction F of the chain conveyor device 28) so It has a concave shape.
Then, the increase dies 11 stored in the increase die storage chamber 23 enter the increase die storage portions 38 of the increase die transport trays 29, 29... Circulated by the drive of the chain conveyor device 28, and obliquely upward Transported to Then, at the upper reversing position of the left and right chains 30, 30 set at the position corresponding to the increase die drop port 24, the increase die transport tray 29 attached to the left and right chains 30, 30 is reversed to increase the number. The increase die 11 in the increase die accommodating portion 38 of the die transport tray 29 falls into the drop passage 26.
Incidentally, as shown in FIG. 4, in the bottom wall 23h of the bottom walls 23h and 23i of the additional die storage chamber 23, it is intended to move upward from the lower reversing position of the left and right chains 30, 30. A guide plate 23G for guiding the increase die 11 to the increase die accommodating portion 38 of the increase die transport tray 29 is provided.

When the additional die transport trays 29 attached to the left and right chains 30, 30 disposed on the left and right sides with respect to the transport direction F are reversed at the upper reversing positions of the left and right chains 30, 30, they are accommodated in the additional die accommodating portion 38. It is detected by the detection sensor 56 immediately before the increase die drop which will be described later at the increase die detection position immediately before the increase die 11 being dropped to the increase die drop port 24. That is, at the increase detection position, the detection light 56X from the light emitting unit 56a of the detection sensor 56 immediately before the increase detection drop is intercepted by the end face of the increase control die 11 and does not reach the light receiving unit 56b. It will be in the state of being
That is, it is configured to be able to be detected by the detection sensor 56 immediately before the increase die drop just before the increase die 11 accommodated and transported in the increase die accommodating portion 38 is naturally dropped to the drop passage 26 at the increase die detection position. It is done.

Then, as shown in FIG. 5, when the additional die transport tray 29 rotates around the center of rotation of the drive shaft 32 at the upper inversion position of the left and right chains 30, 30, the additional die accommodating portion 38 separated from the center of rotation. The centrifugal force is likely to be applied to the increase die 11 accommodated in the lower die, and the increase die 11 accommodated in the increase die accommodating portion 38 is released by the centrifugal force, so the increase die 11 is surely It will fall.
That is, the left and right sides of the increased die transport tray 29 on the front side in the transport direction F are connected to the left and right chains 30, 30 via the connecting shaft 37 and the connecting portion 36, and When rotating around the center of rotation of the drive shaft 32, which is the front side of the conveying direction F connected to the left and right chains 30, 30 at the upper reverse position of the left and right chains 30, 30 of the chain conveyor device 28, Since the centrifugal force is easily applied to the increase die 11 accommodated in the increased die accommodation unit 38 apart from the above, the increase die 11 accommodated in the increase die accommodation unit 38 is at the increase detection position. If it is detected by the detection sensor 56 immediately before the increase in die drop, it is surely discharged from the increase die accommodating portion 38 and falls naturally naturally to the drop passage 26. It becomes possible to reliably supply the increasing die 11 to a common ramp 51 which will be described later.
A belt conveyor device may be used instead of the chain conveyor device 28.

As shown in FIG. 7, the drop passage 26 of the increase die chute 22 is a drop passage extending from the increase die drop opening 24 to the loading machine 7 in order to guide the increase die 11 dropping from the increase die drop opening 24 to the loading machine 7. And a vertical path 50 extending vertically from the additional die drop opening 24 and a common ramp 51 inclined downward from the lower end of the vertical path 50 and extending to the loader 7. Incidentally, the increased die feed path of the explosive supply device 2 is constituted by the increased die transport device 25 and the drop passage 26 described above.
The vertical path 50 is a vertical drop passage having a front and rear width that can be dropped with the central axis 11C of the rod-like increase die 11 maintained horizontal or substantially horizontal, as shown in FIG. An upper wide vertical path 52 having a wide space A1) between 52d and side wall 52e, and a lower narrow vertical path 53 having a narrower width (a space B1 between side wall 52h and a side wall 52i) than the upper wide vertical path 52 .
As shown in FIG. 4, the upper wide vertical path 52 has a rear wall 52a extending from the rear wall 23a of the expansion die storage chamber 23 and a front wall 52b extending from the front wall 23b of the expansion die storage chamber 23 (see FIG. 2). An upper wall 52c extending from the upper wall 23c of the increased die storage chamber 23, a side wall 52d extending downward from the increased die drop port 24, and a other side wall 52e opposed to the one side wall 52d; It is a passage surrounded by an open / close lid 52f (see FIG. 2) for opening and closing an opening shaped along the periphery of the front wall 52b formed in the front wall 52b. The upper wall 52c is formed in the shape of a door that can be opened upward, and by opening the upper wall 52c, the situation on the upper reverse side of the chain conveyor device 28, the vertical path 50, and the inside of the common slope 51 You can check the situation of
The upper wide vertical path 52 is formed such that the distance between the front and rear walls 52b and 52a is longer than the length along the central axis 11C of the increase die 11, and the distance A1 between the left and right walls 52d and 52e Is formed to be longer than the diameter of the increase die 11.
The lower narrow vertical passage 53 has a front wall 53b (see FIG. 2) extending downward from the front wall 52b of the upper wide vertical passage 52 and one side wall extending downward from one sidewall 52d of the upper wide vertical passage 52. 53 d, the other side wall 53 e extending downward from the other side wall 52 e of the upper wide vertical path 52 and the common slope 51.
The lower narrow vertical path 53 is formed such that the distance between the front and rear inner surfaces is longer than the length along the axis of the increase die 11, and the distance B1 between the left and right walls 53d and 53e is greater than the distance A1. Also, it is formed in a dimension which is short and slightly longer than the diameter dimension of the increase die 11.
That is, the lower sides of the left and right walls 52d and 52e of the upper wide vertical path 52 are formed as inclined walls 52h and 52i in which the distance between the left and right walls 52d and 52e is gradually reduced from the distance A1 to the distance B1.

The vertical path 50 collides with the rear end portion (one end portion) 11 a of the increasing die 11 which freely falls in a state where the central axis 11 C is horizontal or almost horizontal, and the central axis 11 C of the increasing die 11 is inclined. It is equipped with an increased die end collision portion 54 to be dropped.
As shown in FIG. 4, the increased-die one-end collision portion 54 has a configuration in which, for example, a round bar made of metal or the like is formed in a V shape, and a mounting portion 55 is formed at one end of the V shape. The mounting portion 55 is located on the left and right of the upper wide vertical path 52 so that the lower end side of the character is located at the boundary between the lower end of the rear wall 52a of the upper wide vertical path 52 and the upper end of It is attached to one of the inner surfaces of the walls 52d and 52e.
That is, the increase die end collision portion 54 is close to the rear wall 52 a which is the inner wall corresponding to the end (rear end) of the increase die at the boundary between the upper wide vertical path 52 and the lower narrow vertical path 53. It is provided.
Then, when the rear end portion 11a of the expansion die 11 that has dropped the upper wide vertical path 52 collides with the inside of the lower end of the V of the expansion die end collision portion 54, the central axis 11C of the expansion die 11 is inclined. In the inclined state, the increase die 11 drops the lower narrow vertical path 53 to reach the common slope 51, and flows down the common slope 51 and the loading machine 7 to reach the loading hose 8.

As shown in FIG. 7, the common inclined passage 51 forms a lower end inclined passage of the lower narrow vertical passage 53, and an upstream inclined passage 51A connected to the lower end discharge port 83 of the lower inclined passage 133 of the uncochute 82 described later. And a downstream slope 51B provided to be continuous with the lower end of the upstream slope 51A.
A common inclined passage 51 and a lower inclined passage 133 of an introduction passage 131 in an unshot 82 described later connected to the upper end side of the common inclined passage 51 and a loading machine 7 connected on the downstream side of the common inclined passage 51. The inclination angle α (refer to FIG. 7) with respect to the vertical line of the continuous slope configured by the slope is formed to be, for example, about 30 ° to 35 °.
The downstream inclined path 51B includes an inlet 51a of the expansion die 11 flowing down the upstream inclination 51A, and an outlet 51b of the expansion die 11 to the loading machine 7, and an opening 51H (FIG. 2) Reference) is formed.
In the downstream inclined path 51B, the inclination angle of the inner upper ridge line 51e connecting the upper end 51c of the inflow port 51a and the upper end 51d of the discharge port 51b is steeper than the inclination angle of the inner lower side ridgeline 51f of the common inclination path 51 Is formed.
That is, since the bore size of the inflow port 51a of the downstream inclined path 51B is formed to be larger than the bore size of the discharge port 51b which is larger than the diameter size of the increase die 11, Even if the front end side of the die 11 hardly collides with the front wall 53b of the lower narrow vertical path 53 and the expansion die 11 behaves in the up and down direction by the reaction of colliding with the lower inner surface of the upstream slope 51A, the front end of the expansion die 11 The side is more likely to enter the inflow port 51a, and the expansion die 11 is smoothly supplied to the loading hose 8.
In addition, it is possible to visually recognize the passage of the increase die 11 or the anvil 12 by looking inside the downstream inclined path 51B through the observation hole 51H, and temporarily, the front end of the increase die 11 or the anch 12 is a discharge port before the discharge port 51b. It is possible to confirm a situation in which the increase die 11 and the anchor 12 get stuck by being caught by the upper end 51 d or the like of 51 b. Further, in this case, by opening the upper wall 52c, it is possible to confirm the clogging condition of the increase die 11 and the ancho 12 and remove the clogging of the increase die 11 and the ange 12.

In the embodiment, the rear end portion 11a of the expansion die 11 falling in the upper wide vertical path 52 collides with the expansion die end collision portion 54, and in a state where the expansion die 11 is inclined, the lower width narrow path from the front end 11b side In order to invade 53, the expansion die 11 after entering the lower width narrow vertical path 53 is restrained from lateral deflection, and after the front end portion 11b of the expansion die 11 first collides with the upstream inclined path 51A Since the rear end portion 11a side of 11 collides with the upstream inclined path 51A, the front end portion 11b side of the expansion die 11 is quickly stabilized on the upstream inclined path 51A, and the front end portion 11b side of the expansion die 11 is the downstream inclined path 51B. Since it becomes easy to enter the inflow port 51a, the increase die 11 can be reliably fed to the common inclined path 51, and clogging of the increase die 11 in the drop passage 26 can be suppressed, and the increase die 11 can be loaded into the hose It will be able to supply smoothly.
Furthermore, since the bore size of the inflow port 51a of the downstream inclined path 51B is formed to be larger than the bore size of the discharge port 51b which is larger than the diameter size of the increase die 11, Even if the front end of the die 11 hardly collides with the front wall 53b of the lower narrow vertical path 53 and the expansion die 11 behaves in the up and down direction by the reaction of colliding with the lower surface of the upstream slope 51A, the front end of the expansion die 11 The 11 b side easily enters the inflow port 51 a, and the expansion die 11 is smoothly supplied to the loading hose 8.

  Temporarily, as shown in FIG. 8, the increase die chute 22 does not have the increase die end collision part 54, and the bore size of the inflow port 51ax of the downstream inclined path 51B and the bore size of the discharge port 51bx are formed to be the same size. In the case of the above configuration, after the rear end 11a of the increase die 11 first collides with the upstream inclined path 51A, the front end 11b of the increase die 11 collides with the upstream inclined path 51A and the front end as shown by arrow Y The front end of the expansion die 11 is caught on the upper wall 53bx of the inflow port 51ax of the downstream ramp 51B, and the rear end 11a of the expansion die 11 is on the road surface of the upstream ramp 51A. As a result of the hooking, there is a high possibility that the increase die 11 will not move into the downstream ramp 51B and the supply hose 8 will not be smoothly supplied.

Further, in the embodiment, since the increase die 11 is allowed to fall naturally to the drop passage 26 without interposing the mechanism such as the inverted receiver disclosed in Patent Document 1, the mechanism such as the inverted receiver is intervened. As compared with the case where it makes it possible, the supply speed of the increase die 11 can be increased, and the increase die 11 can be reliably fed to the common inclined path 51.
On the other hand, in Patent Document 1, after the reverse receiving tray rotated by the air cylinder is made horizontal and received the increase die, the reverse receiving tray is inclined to supply the increase die to the chute (common inclined path). That is, since the increase die is not naturally dropped and supplied to the chute, but is supplied via the reverse receiving tray, the supply speed of the increase die is limited by the driving speed of the reverse receiving tray.
Moreover, in patent document 1, since it is made to incline in the state which mounted the additional die | dye on the saucer, when making it incline, there is a possibility that the additional die | dye on a saucer may run away and can not be sent to a chute successfully.

In the embodiment, the vertical path 50 of the drop passage 26 includes the upper wide vertical path 52 and the lower narrow vertical path 53, and the lower side of the left and right walls 52d and 52e of the upper wide vertical path 52 is the distance A It is formed on the inclined walls 52h and 52i which gradually shrinks to the distance B, and even if the expansion die 11 collides with the inclined walls 52h and 52i on the lower end side of the upper wide vertical path 52, the expansion die 11 is lower lower narrow vertical path 53 Since it is easy to get in, the increase die 11 can be smoothly supplied to the loading hose 8.
That is, the vertical path 50 includes an upper wide vertical path 52 having a wide lateral width and a lower narrow vertical path 53 having a narrower lateral width than the upper wide vertical path 52, and the increased die end collision portion 54 Since it is provided on the rear wall (inner wall) 52a on the side corresponding to the rear end (one end) 11a of the die 11 at the boundary between the upper wide vertical path 52 and the lower narrow vertical path 53, The rear end portion 11a of the expansion die 11 falling from the opening 24 to the upper wide vertical path 52 collides with the expansion die end collision portion 54, and the expansion die 11 is inclined and enters the lower narrow vertical path 53. The lateral deflection of the expansion die 11 after entering the lower narrow vertical path 53 is suppressed, and the expansion die 11 can be stably supplied to the loading hose 8.

As shown in FIG. 7, the sensor group 27 is provided on the vertical path 50 and detects the sensor just before the increase die drop which detects the increase die 11 just before the drop, and the sensor path 27 is provided on the vertical passage 50 and the die 11 falls It is comprised by the increase die fall detection sensor 57 which detects whether it is.
The detection sensor 56 immediately before the increase in the drop of the die is, for example, an optical sensor provided with a light emitting portion 56a and a light receiving portion 56b positioned on the same horizontal plane. For example, the light emitting portion 56a is a rear wall 52a of the upper wide vertical path 52 A light receiving portion 56b is provided on the upper end side and the light receiving portion 56b is provided on the upper end side of the open / close lid 52f to detect whether or not the increase die 11 has reached a position immediately before the increase die drop.
The increase die drop detection sensor 57 is, for example, a light emitting portion 57a located on the same slope line inclined in the same direction as the common slope 51 above the common slope 51 and located on the lower side of the same slope line. The light emitting portion 57 a is provided on the lower end side of the rear wall 52 a of the upper wide vertical path 52, and the light receiving portion 57 b is an anterior wall of the lower narrow vertical path 53. It is provided at 53b to detect whether or not the increase die 11 has dropped. The additional die drop detection sensor 57 may be configured by, for example, a light emitting portion 57 a and a light receiving portion 57 b which are disposed on a slope which is inclined in the opposite direction to the common slope 51 above the common slope 51.
That is, the increase die drop detection sensor 57 has one end side wall (rear wall 52a) of the vertical path 50 located on one end (rear end portion 11a) side of the increase die 11 just before drop and the other end of the increase die 11 just before drop A light emitting portion 57a and a light receiving portion 57b provided on the other of the side walls (front wall 52b) of the other end of the vertical path 50 located on the front end portion 11b) side The light receiving portion 57b is vertically displaced from the light receiving portion 57b, and the increasing die 11 falling in the vertical path 50 is detected based on the detection light 57s which is vertically transmitted and received between the light emitting portion 57a and the light receiving portion 57b. It is configured to

According to the embodiment, the detection sensor 56 for detecting the increase die 11 immediately before the fall is provided with the detection sensor 56 just before the increase die drop. Therefore, it is determined whether the increase die 11 has reached the position just before the increase die drop. It can be detected whether or not the die 11 is not in the increase die storage chamber 23, or that any failure has occurred in the increase die transfer device 25 or the like.
In the case where the increase die 11 falling with the central axis 11C horizontal or substantially horizontal is detected by an optical sensor provided with a light emitting portion and a light receiving portion positioned on the same horizontal surface, the upper wide vertical path The detection range in which the increase die 11 falling in a state in which the central axis 11C falls horizontally or substantially horizontally in the inside 52 can be detected is the range of the axis diameter of the increase die 11 and the detection range in which the increase die 11 can be detected is reduced. There is a possibility of omission of detection.
On the other hand, in the embodiment, since the increased die drop detection sensor 57 is provided on the inclined line that inclines in the vertical direction, the inclination detection light 57s transmitted and received between the light emitting unit 57a and the light receiving unit 57b arranged on the inclined line 7), the detection range capable of detecting an increase in die 11 falling in a state in which the central axis 11C is horizontal or substantially horizontal in the upper wide vertical path 52 is enlarged, and the central axis 11C falls in a horizontal or substantially horizontal state. Thus, it is possible to reliably detect the increased die 11.
Then, if the increase die passing detection sensor 143 described later does not detect the increase die 11 within a predetermined time after the increase die drop detection sensor 57 detects the increase die 11, the control device 5 detects the increase die drop detection sensor 57. It is possible to recognize that the increase die 11 is clogged in the path from the installation position of the to the installation position of the increase die passage detection sensor 143.

As shown in FIGS. 9 and 13, the common slope 51 is provided with an airflow generation means 60 for generating an air flow directed to the side of the loading machine 7 in the common slope 51.
The airflow generation means 60 includes an air supply head 61 provided on the upper end side of the upstream slope 51A in the common slope 51, and an air supply head 62 provided on the upper end side of the downstream slope 51B in the common slope 51. And a compressed air supply device 63 for supplying compressed air to each of the air supply heads 61 and 62.
That is, the airflow generation means 60 supplies air from the outside on the upper end side of the upstream inclined path 51A and the upper end side of the downstream inclined path 51B to the inside of the upstream inclined path 51A and the downstream inclined path 51B. It is configured to provide an air flow towards the
The air supply heads 61 and 62 are installed such that the tapered injection ports communicate with the common slope 51.

That is, the airflow generation means 60 is provided symmetrically about the central axis of the common inclined path 51 as the target axis.
That is, the airflow generation means 60 for generating the airflow directed to the side of the loading machine 7 in the common inclined passage 51 penetrates the left wall surface and the right wall surface of the upper end side of the upstream inclined passage 51A, The left and right air supply heads 61, 61 for generating an air flow directed from the upper end side of the 51A toward the loading machine 7 and the left wall surface and the right wall surface of the upper end side of the downstream inclined passage 51B respectively penetrate the downstream inclined passage The left and right air supply heads 62 and 62 for generating an air flow directed from the upper end side of 51 B toward the loading machine 7 and a compressed air supply device 63 for supplying compressed air to the respective air supply heads 61 and 62 .
Then, the control device 5 controls the compressed air supply device 63 so that air is supplied from the compressed air supply device 63 into the common inclined passage 51 via the air supply heads 61 and 62, so that the inside of the common inclined passage 51 is obtained. At the same time, an air flow directed to the loader 7 is generated.
As described above, the air supply head constituting the air flow generation means 60 is symmetrical in left and right symmetry with the central axis of the common slope 51 as the target axis on the upper end side of the upstream slope 51A and the upper end side of the downstream slope 51B. Although it is preferable to provide, at least one or more may be provided in the common slope 51.

According to the embodiment, since the air flow generation means 60 for generating the air flow directed to the side of the loading machine 7 is provided in the common slope 51, the additional die 11 dropped from the vertical path 50 to the common slope 51 is smoothed. Can be supplied to the loading hose 8.
In particular, an air flow directed to the side of the loading machine 7 was generated in the common ramp 51 before the die 11 was dropped to the common ramp 51, whereby the vertical path 50 dropped to the common ramp 51. The increase die 11 can be supplied to the loading hose 8 more smoothly.
That is, by generating an air flow in the common ramp 51 in the direction of increasing die flow downward, it is possible to reduce the friction between the additional die 11 dropped to the common ramp 51 and the inner wall of the common ramp 51. It is possible to eliminate the situation in which the die 11 becomes stuck and clogged in the common ramp 51.
In addition, since the airflow generation means 60 supplies air from the upper and lower sides of the upper end side of the upstream inclined path 51A connected to the lower end of the vertical path 50 and the upper and lower sides of the upper end side of the downstream inclined path 51B, the upstream inclined path Air can be uniformly supplied to the inside of the upstream ramp 51A and the downstream ramp 51B from the left and right of the downstream ramp 51A and the downstream ramp 51B, and the expansion die 11 becomes stuck in the common ramp 51 and clogged. Since the situation can be surely suppressed, it is possible to more smoothly supply the increase die 11 dropped from the vertical path 50 to the loading hose 8.

The container supply device 3 is a device for supplying the annko 12 to the loading hose 8.
As shown in FIG. 10, the delivery apparatus 3 includes a part feeder 70, a belt conveyor 72 for supplying the annko 12 to the part feeder 70 from an anko storage 71 provided above the part feeder 70, and a part feeder 70. A passage 73 connecting the upstream side conveyance conveyor 74, an upstream side conveyance conveyor 74 receiving the ancho 12 that has passed through the parts feeder 70 and the passage 73, and conveying it downstream, an ancole conveyed by the upstream side conveyance conveyor 74 12, the downstream side conveyance conveyer 76 which conveys the ancho 12 corrected through the correction device 75 to the ancho falling portion 77, and the downstream side conveyance conveyer 76 convey the anko fall portion 77 The uncoster 80 that receives the anko 12 that falls through and the lower end outlet of the uncoster 80 The Anko 12 falling from 1 and a ANKO chute 82 to be supplied to the pumping device 4.
That is, the package supply device 3 includes an ancho storage room 71 in which the anko 12 is placed, a parts feeder 70 for aligning and conveying the anko 12 sent by the belt conveyor 72 from the anko storage room 71, and a passage 73 from the parts feeder 70. Upstream conveyance conveyor 74 which conveys the anko 12 which has been conveyed through the correction device 75 to the correction device 75, the correction device 75 which corrects the shape of the anko 12 which has been conveyed by the upstream conveyance conveyor 74, and A single-system anko conveyance device configured to include the downstream side conveyance conveyor 76 that conveys the formed anko to the anko falling portion 77, and a plurality of anko that store a plurality of the anko 12 falling from the anko falling portion 77 Anko 12 falling from stockers 80, 80 and lower end discharge ports 81, 81 of uncosters 80, 80 Leading to the respective loading hose 8,8 and a plurality of drop channels. The drop path is, as shown in FIG. 13, configured by an unchout 82 and a loader 7 connected to the discharge port 51 b at the lower end of the common inclined path 51 that is downstream of the uncoshoot 82.

  As shown in FIG. 10, after being provided on the rear side of the belt conveyor 72, the Anko storage room 71 is provided on the belt conveyor 72 on which the anvil 12 is placed, side walls 71a and 71a provided on both sides of the belt conveyor 72. The belt conveyor 72 is driven so that the anvil 12 placed on the belt conveyor 72 moves in the conveyance direction of the belt conveyor 72 and falls onto the inner bottom surface 70b of the part feeder 70. It is done.

The parts feeder 70 includes a vibration mechanism (not shown) and a bowl 70 a vibrated by the vibration mechanism, and the control and control of the drive and stop of the vibration mechanism is controlled by the control device 5. The bowl 70a includes a bottom portion and a peripheral wall portion 70c provided so as to rise above the periphery of the bottom portion. The bottom inner surface 70b is formed in a conical surface shape. On the inner circumferential surface of the peripheral wall portion 70c, there is formed a spiral supply passage 70d which spirally extends upward from the inner bottom surface 70b.
The vibration mechanism is driven to vibrate the bowl 70a and the belt conveyor 72 is driven to center the anvils 12 stacked and mounted on the belt conveyor 72 at the center of the conical bottom surface 70b of the part feeder 70. When dropped to the side, the anvil 12 moves around the inner bottom surface 70 b and then moves upward via the spiral supply path 70 d and moves onto the upstream conveyance conveyor 74 via the passage 73. .

An interval detection sensor for determining the presence or absence of an interval between the annulus 12 and 12 adjacent to each other along the conveying direction F1 conveyed by the upstream side conveyance conveyor 74 to the end side of the upstream side conveyance conveyor 74 It has 85.
The interval detection sensor 85 includes, for example, a light emitting unit 86 and a light receiving unit 87 which are disposed obliquely to the transport direction F1. Here, when the light from the light emitting unit 86 is detected by the light receiving unit 87 by passing through the space between the adjacent anchors 12 and 12, the parts feeder 70 continues to be driven, and the light from the light emitting unit 86 For example, when the light is blocked by the anchor 12 for 2 seconds and not detected by the light receiving unit 87, the driving of the parts feeder 70 is stopped, and then the light from the light emitting unit 86 is detected by the light receiving unit 87 After 0.2 seconds, the parts feeder 70 is driven. As described above, using the interval detection sensor 85 configured by the light emitting unit 86 and the light receiving unit 87 arranged obliquely with respect to the conveyance direction F1, the conveyance state of the scale 12 is detected, and the conveyance state of the scale 12 is detected. By controlling the driving and stopping of the parts feeder 70 based on the above, for example, the annko 12 is excessively fed from the parts feeder 70 to the upstream side conveyance conveyor 74, and In this case, collision with T.12 can be prevented, and it can be prevented that the annulus 12 overflows from on the upstream side conveyance conveyor 74.
In addition, when the said space | interval detection sensor is comprised by the light emission part and the light reception part which were arrange | positioned so as to be orthogonal to the conveyance direction F1, for example, the space | interval between the adjacent scale 12 is small. Even if the interval is small, the light receiving unit detects the light from the light emitting unit, and the parts feeder 70 continues to be driven. Therefore, the ancho 12 is excessively fed from the parts feeder 70 to the upstream conveyance conveyor 74 As a result, the adjacent anchor 12 and the adjacent anchor 12 on the upstream side conveyance conveyor 74 easily collide with each other, which is not preferable. On the other hand, as in the embodiment, if the interval detection sensor 85 configured by the light emitting unit 86 and the light receiving unit 87 disposed obliquely with respect to the transport direction F1 is used, the distance between the adjacent scale 12 and 12 can be obtained. If the interval is a minute interval, the light from the light emitting unit 86 is blocked by the anvil 12 and is not detected by the light receiving unit 87, and the driving of the part feeder 70 is stopped. Excess feed of the annko 12 to the side conveyance conveyor 74 is suppressed, and it is possible to prevent the annko 12 from overflowing on the upstream side conveyance conveyor 74.
Further, in the control device 5, the cylindrical storage portion 115 described later in the empty state in the uncosted loader 80 is located immediately below the anvil drop portion 77, and the bottom receiving portion 116 described later of the uncosted storage 80 is a cylindrical stored portion After recognizing that the predetermined position in 115 is reached, the upstream side conveyance conveyor 74, the correction device 75, and the downstream side conveyance conveyor 76 are simultaneously driven, and a predetermined number of hooks 12 are accommodated in the cylindrical accommodation portion 115. After recognizing that it has been carried out, the upstream conveyor 74, the correction device 75, the downstream conveyor 76 before the next anvil 12 falls from the downstream conveyor 76 into the cylindrical container 115 of the uncoster 80. Stop at the same time.
That is, while the parts feeder 70, the upstream side transfer conveyor 74, the correction device 75, and the downstream side transfer conveyor 76 are driven, the above-mentioned interval detection sensor 85 is used to detect the conveyance state of the anvil 12, and the conveyance of the anko 12 is performed. By controlling the driving and stopping of the parts feeder 70 based on the state, it is suppressed that the ancho 12 is excessively fed from the parts feeder 70 to the upstream side conveyance conveyor 74, and the anko 12 overflows from above the upstream side conveyance conveyor 74. It prevents you from leaving.

  The correction device 75, as shown in FIG. 11, is configured by arranging four rollers 90, 90... In which the outer peripheral surface 91 is formed in a curved concave shape in cross section and curving the four rollers 90, 90.

To be corrected. That is, it is an apparatus which corrects the Anko 12 which is deformed during conveyance from the Anko storage 71 to the correction device 75 into a predetermined round bar shape.

  That is, the anvil 12 dropped from the belt conveyor 72 to the inner bottom surface 70b of the parts feeder 70 is transferred to the upstream side conveyance conveyor 74 via the spiral supply passage 70d and conveyed to the correction device 75 by the upstream side conveyance conveyor 74 After being corrected into a predetermined round bar shape, the sheet is conveyed by the downstream side conveyance conveyor 76 and dropped to the uncoster 80 through the anvil drop portion 77.

On the side wall at the end of the downstream transport conveyor 76 in the transport direction, annko drop detection is performed to detect whether the anvil 12 has fallen from the downstream transport conveyor 76 into the cylindrical accommodation portion 115 of the uncoster 80 described later. A sensor 95 is provided.
The anchor drop detection sensor 95 includes, for example, a pair of light emitting units 96 and light receiving units 97 provided on the left and right orthogonal to the conveyance direction of the downstream side conveyance conveyor 76. When the controller 5 inputs that the light from the light emitting unit 96 has reached the light receiving unit 97 after the light from the light emitting unit 96 is blocked by the ancho 12, the one annular 12 is transported downstream It is determined that the conveyor 76 has dropped into the cylindrical housing portion 115 of the uncoster 80 via the ancho dropping portion 77.
Whether or not the anchor 12 has fallen from the downstream conveyor 76 by the anchor drop detection sensor 95, that is, there is any failure in the path from the belt conveyor 72 to the downstream conveyor 76, or Whether 12 or not can be detected.

The anvil drop portion 77 is formed in a vertically extending cylindrical path in which the central axis conveyed by the downstream side conveyance conveyor 76 vertically drops the attitude of the anvil 12 in the horizontal state after making the attitude of the anvil 12 in the horizontal state inclined. .

The both side walls 102, 102 are respectively provided with facing holes 103, 103 facing each other, and an annco drop portion 77 which falls from the downstream side conveyance conveyor 76 through the facing holes 103, 103. It is comprised so that visual confirmation of 12 is possible.
The opposing inclined wall 101 is an inclined wall formed to be inclined from the lower edge located parallel to the lower edge of the guide inclined wall 100 in a direction opposite to the inclination direction of the guide inclined wall 100. That is, the guide inclined wall 100 and the facing inclined wall 101 are formed to approach each other as the upper edge approaches the lower edge.
The punch-out part 99 is formed in a cylindrical path extending downward from the lower edge of the punch-in part 98 in order to drop the punch 12 whose posture has been changed in an oblique state by the punch-in part 98 in a vertical state.
When the anko 12 falls into the anko introduction portion 98, the anko 12 is vertical after the fall speed is reduced by the friction between the anko 12 and the guide inclined wall 100 or the friction between the anko 12 and the opposite inclined wall 101. In this state, since it falls from the anchor lead out portion 99 onto the bottom support portion 116 of the uncosted loader 80, the impact force applied to the anchor 12 when the anchor 12 collides with the bottom support portion 116 of the uncosted loader 80 can be reduced. 12 deformations can be suppressed.

The loader 7 includes an upstream inclined pipe 140 connected in communication with the discharge port 51 b of the common inclined path 51, a downstream inclined pipe 141, a lower end of the upstream inclined pipe 140 and an upper end of the downstream inclined pipe 141. , And a pressure in the loading hose 8 to detect whether the booster die 11 has passed through the pipeline of the loading machine 7 or not. And a water injection device 145 for supplying mist into the downstream inclined pipe 141 and the loading hose 8.

  The lower end discharge port 146 of the downstream inclined tube 141 of the loading machine 7 and one end of the loading hose 8 are connected, the other end of the loading hose 8 and one end of the loading pipe 9 are connected, and the other end of the loading pipe 9 ) Side is inserted into the loading hole H.

  The pumping air supply mechanism 142 includes a connection pipe 147 that allows the upstream inclined pipe 140 and the downstream inclined pipe 141 to communicate with each other, and a loading valve 148 that is interposed in the middle of the pipe of the connection pipe 147 to open and close the pipe. And a compressed air blowing nozzle 149 for blowing compressed air toward the valve body 152 of the loading valve 148 in a state where the pipe line is closed from a position downstream of the position of the valve body 152 of the loading valve 148; The apparatus includes a compressed air supply device 150 for supplying compressed air to 149, and a control device 5 for controlling supply and stop of supply of air from the compressed air supply device 150 to the compressed air spray nozzle 149.

The loading valve 148 has a valve body 152 which opens and closes a pipe line by a drive source 151 such as compressed air, hydraulic pressure or a motor.
In a state where the valve body 152 of the loading valve 148 closes the conduit, the compressed air from the compressed air spray nozzle 149 is blown toward the valve body 152 from a position downstream of the valve body 152, The air that collides with 152 becomes a flow of air directed to the loading hose 8 side, and the increased die 11 or the anvil 12 supplied to the loading hose 8 is pumped to the charging hole H by the pressure of the flow of air.

  The increase die passage detection sensor 143 is constituted by, for example, a light emitting part 143a and a light receiving part 143b (see FIG. 2) installed on opposing pipe walls positioned on a straight line orthogonal to the central axis of the pipe line of the loading machine 7. Thus, it is a sensor that detects the passage of the increase die 11 at a position downstream of the valve body 152 of the loading valve 148.

Just before the increase in die drop detection sensor 56, the increase die fall detection sensor 57, the increase die passage detection sensor 143 provided in the loading machine 7, and the increase die monitoring means in the control device 5 which inputs signals from these sensors And 161 constitute a die increase monitoring device.

The increase die monitoring device inputs signals from these sensors, and indicates information such as the actual number of increase dies 11 supplied to the pumping device 4 and a defect in the supply system of the increase dies 11. Inform the worker etc via

The pressure detection device 144 includes an air communication passage 155 communicating with the inside of the downstream inclined pipe 141 located downstream of the position where the downstream inclined pipe 141 and the compressed air blowing nozzle 149 communicate with each other, The pressure sensor 156 detects the pressure of the air taken in through the passage 155, and the control device 5 instructs the pumping air supply mechanism 142 to perform the clogging elimination process based on the output from the pressure sensor 156.
When the pressure detected by the pressure sensor 156 becomes equal to or higher than a predetermined value, the control device 5 determines that clogging is occurring in the loading hose 8 and stops the supply of the increase die 11 or the ancho 12 After that, the pressure feeding air supply mechanism 142 is instructed to perform the clogging elimination process. As a result, the pumping air supply mechanism 142 closes the pipe line with the valve body 152 of the loading valve 148 and blows the compressed air from the compressed air spray nozzle 149 only for a predetermined time toward the valve body 152 to The air which collides with 152 generates a flow of air flowing toward the loading hose 8 side for a predetermined time, thereby pumping the increased die 11 or the anvil 12 clogged in the loading hose 8 by the pressure by the flow of the air It is made to be discharged from the tip opening of the loading pipe 9. After generating a flow of air flowing toward the loading hose 8 for a predetermined time, if the control device 5 determines that the pressure detected by the pressure sensor 156 does not exceed the predetermined value, the control device 5 performs the loading operation. It is determined that the clogging in the hose 8 has been eliminated, and the clogging elimination processing is ended. In addition, after generating a flow of air flowing toward the loading hose 8 for a predetermined time, if the control device 5 determines that the pressure detected by the pressure sensor 156 is still equal to or higher than the predetermined value, the control device 5 Then, the pressure feeding air supply mechanism 142 is again instructed to perform the clogging elimination processing, and the clogging elimination processing is instructed until the clogging in the loading hose 8 is eliminated.
That is, the controller 5 determines whether or not clogging of the increase die 11 or the anchor 12 has occurred in the loading hose 8 based on the detected value from the pressure sensor 156 communicating with the inside of the loading hose 8 via the air communication path 155. If it is determined that clogging of the increase die 11 or the anchor 12 has occurred in the loading hose 8, compressed air is sent into the loading hose 8 to load the increase die 11 or the anchor 12 in the loading hose 8. Since the pressure feed air supply mechanism 142 is instructed to perform the clogging elimination processing to be discharged from the distal end opening of the pipe 9, it is possible to quickly eliminate the clogged state in the loading hose 8 of the increase die 11 and the annulus 12.

The water injection device 145 is provided so as to communicate with the inside of the downstream inclined pipe 141 located downstream of the position where the downstream inclined pipe 141 and the compressed air blowing nozzle 149 communicate with each other, and the downstream injection pipe An injection nozzle 157 for injecting water into 141, a water supply source 158, and a control device 5 for controlling supply and stop of water supply from the water supply source 158 to the injection nozzle 157 are provided.
Accordingly, the water supplied from the water supply source 158 to the injection nozzle 157 and jetted into the downstream inclined pipe 141 is diffused by the flow of air flowing toward the loading hose 8 and becomes mist, and the downstream inclined pipe 141 By forming a liquid film on the inner surface of the pipeline and the inner surface of the loading hose 8, the increase die 11 or the anco 12 slides on the liquid film, and the increase die 11 or the ante 12 is pumped more smoothly to the loading hole H Will be

Next, the flow of increased die supply will be described.
The increase die 11 accommodated in the increase die storage chamber 23 of the hopper 21 is conveyed from below the increase die storage chamber 23 to the increase die drop opening 24 by the increase die transfer device 25, and the drop passage 26 from the increase die drop opening 24. Fall into At this time, the increase die 11 is conveyed by the increase die transport tray 29 one by one to the increase die drop port 24 with the central axis 11C being horizontal, and starts to fall with the central axis 11C horizontal or almost horizontal, Thereafter, the rear end portion (one end portion) 11a of the increase die 11 which has dropped the upper wide vertical path 52 of the drop passage 26 collides with the increase die end collision portion 54, whereby the increase axis 11 is inclined at the central axis 11C. In this state, the lower narrow vertical path 53 is dropped in the inclined state to reach the common slope 51, and flows down the common slope 51 and the loader 7 to reach the loading hose 8.
That is, the vertical path 50 is configured such that the upper wide vertical path 52 and the lower narrow vertical path 53 are continuous, and the rear end portion 11 a of the increase die 11 free to fall from the increase die drop port 24 is the upper wide vertical path 52 By colliding with the increase die end collision portion 54 provided at the boundary between the lower narrow vertical path 53, the posture of the increase die 11 is configured to be inclined and led to the common slope 51, so The die 11 is smoothly supplied to the loading hose 8 from the die drop port 24 through the upper wide vertical path 52, the lower narrow vertical path 53, the common slope 51, and the loading machine 7.

Further, the increase die 11 is detected by the detection sensor 56 immediately before the increase die drop at a position immediately before the increase die 11 is dropped, and the number of drops of the increase die 11 falling the vertical path 50 is detected by the increase die drop detection sensor 57 Do.
Further, the left and right sides of the increased die transport tray 29 on the front side in the transport direction F of the chain conveyor device 28 are connected to the left and right chains 30 and 30 via the connecting shaft 37 and the connecting portion 36. Since the housing portion 38 is provided, when rotating about the rotation center of the drive shaft 32 at the upper inversion position of the left and right chains 30, 30 of the chain conveyor device 28, the increased die housing portion separated from the rotation center It becomes easy to apply a centrifugal force to the increase die 11 accommodated in 38. Therefore, after the increase die 11 accommodated in the increase die accommodation portion 38 is detected by the detection sensor 56 immediately before the increase die drop at the increase die detection position, it is reliably discharged from the increase die accommodation portion 38. Since the free fall onto the common slope 51, the supply speed of the increase die 11 from the chain conveyor device 28 to the common slope 51 can be increased.
Further, by configuring the increase die drop detection sensor 57 as an optical sensor including the light emitting portion 57a and the light receiving portion 57b disposed on the inclined line inclined in the vertical direction, the central axis 11C in the upper wide vertical path 52 is horizontal. Alternatively, the detection range in which the increase die 11 falling in a substantially horizontal state can be detected is enlarged, and the increase die 11 falling in a state in which the central axis 11C is horizontal or substantially horizontal can be detected reliably.

  In addition, the air flow generation means 60 generates an air flow directed to the side of the loading machine 7 by the air flow generation means 60 before the increase die 11 falls to the common slope 51, thereby the vertical path 50 It is possible to prevent stagnation (clogging) of the increase die 11 falling on the common slope 51 on the common slope 51 and supply the increase die 11 dropped on the common slope 51 from the vertical path 50 to the loading hose 8 more smoothly. It will be.

Next, the flow of the ancho feeding is described.
After the Anko 12 placed on the belt conveyor 72 of the Anko storage area 71 falls to the center side of the conical inner surface 70b of the parts feeder 70, it moves around the inner surface 70b, and the spiral supply passage 70d, After moving on the upstream side conveyance conveyor 74 via the passage 73 and being corrected via the correction device 75, the ink is conveyed by the downstream side conveyance conveyor 76 and falls to the uncoster 80 via the anvil dropper 77. .
Under the present circumstances, since it is detected by the ancho fall detection sensor 95 at the position of the conveyance direction terminal end side of the downstream side conveyance conveyor 76, the control device 5 supplies the ancho 12 because it is detected. It is possible to recognize a system failure and the like, and to perform an output to that effect.

The uncoster 80 can stock (store) a predetermined number of anchors 12 in the cylindrical housing portion 115. Therefore, the plurality of anchos 12 stored in the uncoster 80 can be supplied to the loading hose 8 at one time, and it becomes possible to load the plurality of ankos 12 into the charge hole H in one pumping operation. Work time can be shortened.
For example, in the case where four anchors 12 are stocked in the cylindrical housing portion 115, the bottom receiving portion 116 is positioned substantially at the center between the upper and lower portions in the cylindrical housing portion 115. In order to line up in the vertical direction, only two Anko 12 are received. After receiving the two anchors 12, the bottom receiving portion 116 is positioned below the lower end discharge port 81 of the cylindrical housing portion 115. After that, by receiving only two anchors 12, four anchors 12 are aligned in the vertical direction in the cylindrical housing portion 115.
In this manner, the base receiving portion 116 is moved between the upper and lower portions in the cylindrical housing portion 115, and the predetermined number of anvils 12 housed in the cylindrical housing portion 115 is divided and received a plurality of times. The falling distance of the anchor 12 from can be shortened, and the impact applied to the anchor 12 at the time of falling can be reduced, so that it is possible to suppress the situation where the anchor 12 is deformed by the impact of the drop.
Also, at this time, the upper anchor detecting sensor 119 detects the anvil 12 located at the uppermost position in the cylindrical housing portion 115, and the lower anchor detecting sensor 120 is at the lowermost position in the cylindrical housing portion 115. By detecting 12, it is output to the control device 5 that four (predetermined number) of anchors 12 are accommodated in the cylindrical accommodation portion 115.
The control device 5 detects a detection signal when the upper anchor detecting sensor 119 detects the anvil 12 positioned at the uppermost position in the cylindrical housing 115 and the lower anchor detecting sensor 120 at the lowermost position in the cylindrical housing 115 It is possible to recognize that a predetermined number of four anchos 12 have been accommodated in the cylindrical housing portion 115 by inputting both of the detected anchols 12 and the detected signal, and after recognition, the uncoster 80 is moved in the horizontal direction. To move the lower end discharge port 81 above the inlet 130 of the uncoil chute 82, and then to level off the bottom receiving portion 116 below the lower end discharge port 81 of the cylindrical housing portion 115. It is possible to reliably perform the discharging operation of causing the predetermined number of four anvils 12 in the cylindrical housing portion 115 to drop from the lower end discharge port 81 by moving in the direction.
In this case, in the control device 5, for example, the empty tubular housing portion 115 is positioned directly below the anvil drop portion 77, and the bottom support portion 116 is positioned approximately at the center between the upper and lower portions in the cylindrical housing portion 115. After recognizing that it has been done, the upstream conveyor 74, the correction device 75, and the downstream conveyor 76 are simultaneously driven. In addition, after recognizing that the four anchors 12 are accommodated in the cylindrical housing portion 115, the control device 5 blocks the light from the light emitting unit 96 of the anchor drop detection sensor 95 at the fifth anchor 12. At the moment when it is done, the upstream side transfer conveyor 74, the straightening device 75, and the downstream side transfer conveyor 76 are simultaneously stopped. That is, when the controller 5 inputs that the light from the light emitting unit 96 has reached the light receiving unit 97 after the light from the light emitting unit 96 is blocked by the ancho 12, the one annular 12 is transported downstream At the moment when the light from the light emitting unit 96 of the drop detection sensor 95 is blocked by the fifth drop 12 in order to determine that it has dropped from the conveyor 76, the fifth drop 12 from the downstream side transfer conveyor 76 It has not fallen, and the control device 5 has not determined that the fifth ancho 12 has fallen from the downstream side conveyance conveyor 76. That is, after the control device 5 recognizes that four anchors 12 are stored in the cylindrical storage portion 115, the upstream side conveyance is performed before the fifth insertion 12 is dropped from the downstream conveyance conveyor 76. The conveyor 74, the straightening device 75, and the downstream conveyor 76 are simultaneously stopped.
The dropped anko 12 falls naturally to the inside of the loading hose 8 from the introduction port 130 of the anko chute 82 through the inside of the anko chute 82 and the inside of the loading machine 7.
The number of anvils 12 received by the bottom receiving portion 116 at one time and the number of the anvils 12 discharged at one time from the lower end discharge port 81 of the cylindrical housing portion 115 are the vertical movement of the bottom receiving portion 116 and the bottom receiving By controlling the horizontal movement of the part 116, it is possible to freely decide. For example, control is made to move the bottom receiving portion 116 downward each time one anvil 12 is received, and after a predetermined number of anvils 12 are stored in the cylindrical housing portion 115, the The horizontal movement of the base portion 116 may be controlled so as to discharge one by one.
In this case, the control device 5 recognizes that the empty cylindrical housing portion 115 is located immediately below the anvil drop portion 77 and that the bottom receiving portion 116 has reached a predetermined position in the cylindrical housing portion 115. Then, the upstream conveyance conveyor 74, the straightening device 75, and the downstream conveyance conveyor 76 are simultaneously driven, and after it is recognized that a predetermined number of anvils 12 are accommodated in the cylindrical accommodation unit 115, the next The upstream conveyance conveyor 74, the straightening device 75, and the downstream conveyance conveyor 76 are simultaneously stopped before the drop 12 falls from the downstream conveyance conveyor 76.

In the embodiment, in a state where the loading valve 148 of the loading machine 7 is opened, the increase die 11 or the annulus 12 which has passed through the pipeline of the loading machine 7 falls into the loading hose 8.
Thereafter, the control device 5 drives the pumping air supply mechanism 142. The pumping air supply mechanism 142 closes the loading valve 148 and blows compressed air toward the valve body 152 of the loading valve 148 whose conduit is closed. Then, after the compressed air collides with the valve body 152, the expansion die 11 or the anvil 12 already supplied in the loading hose 8 is pressed, and the expansion die 11 or the anvil 12 passes the loading hose 8 and the loading pipe 9. The charge hole H is loaded.

In the embodiment, since the two pumping devices 4 and 2 and the two explosive feeding devices 2 and 2 which individually supply the dies 11 to the two pumping devices 4 and 4 are provided, two points of the face The die loading operation can be performed in parallel.
In addition, the delivery apparatus 3 is a system of anko conveyance system (parts feeder 70, upstream conveyance conveyor 74, correction apparatus 75, downstream conveyance conveyor 76) from the anko storage room 71 to the anko dropping portion 77, The two anko drop supply devices (an coster 80, an ancochute 82) that individually supply the anko 12 to the pumping devices 4, 4 respectively by receiving an anko 12 individually from an anco carrier of Since the anvils 12 are distributed and supplied from the one anko conveyance device to the two Anko drop supply devices, the unco loading operation can be performed in parallel at two places of the face.
In other words, the package supply device 3 has a single-system conveyance path for transporting the anko from the anko storage room 71 to the anko dropping portion 77 and two anko as a storage device for storing the anko falling from the anko dropping portion 77. Stockers 80, 80, two uncochesutes 82, 82 as drop paths for guiding the anchos 12 falling from the lower end discharge ports 81 of the two uncosters 80, 80 to the pumping device 4, two pumping devices 4, 4 Is equipped.

The flow of the loading operation of the increase die 11 and the anchor 12 will be described.
After activating the explosive loading device 1, the operator X who performs the loading operation with the face K inserts the tip end side of the loading pipe 9 with the parent die 10 attached to the tip into the charge hole H, and the operator X or work assistance An instructor such as a person transmits a parent die loading instruction to the control device 5 using the instruction device 6 such as a remote controller. The control device 5 having received the parent die loading instruction instructs the pumping air supply mechanism 142 to perform the pumping operation to close the loading valve 148, and then the air flowing toward the distal end side of the loading pipe 9 is supplied. The parent die 10 is pressed by the pressure of the air flow and is loaded to the end of the charge hole H.

Next, the instructor uses the instruction device 6 to transmit to the control device 5 an increase-die loading instruction that requests loading of a predetermined number (for example, two) of the increase dies 11.
The control device 5 having received the increase die loading instruction drives the air flow generation means 60 so that an air flow directed to the side of the loading machine 7 is supplied into the common slope 51.
Then, the control device 5 having received the increase die loading instruction instructs the increase die transfer device 25 to perform the transfer operation, whereby the increase die transfer device 25 transfers the increase dies 11 one by one to the increase die drop port 24. An increase die 11 is supplied to the loading hose 8 via the increase die chute 22 and the loading machine 7. At this time, since the air flow directed to the side of the loading machine 7 is supplied into the common slope 51, the expansion die 11 is smoothly supplied to the loading hose 8.
The control device 5 inputs a predetermined number of signals indicating that the increase die 11 has passed from the increase die passage detection sensor 143, determines that the predetermined number of increase dies 11 are supplied to the loading hose 8, and then supplies pressurized air. By instructing the mechanism 142 to perform the pumping operation, a predetermined number of the expansion dies 11 supplied to the loading hose 8 are pressed by the pressure by the flow of air and are pumped to the loading hole H and loaded into the loading hole H Be done.
The control device 5 instructs the pumping air supply mechanism 142 to perform the pumping operation, and confirms that the loading operation of the predetermined number of the increase dies 11 is completed. A predetermined number of increase-in-die loading operation end confirmations are displayed on the end sound output after the control device 5 confirms completion of the feed operation to the pumping air supply mechanism 142 or on a display outside the figure, or An operator or a supporter can confirm by a response etc. when 11 passes through the inside of the loading pipe 9.

After confirming that the predetermined number of additional die loading operations have been completed, the instructor then uses the pointing device 6 to request the control device 5 to load a predetermined number (for example, four) of the unco 12 and an unco loading instruction Send.
The control device 5 having received the unco loading instruction issues a transfer operation instruction to the unco transport device, and transmits a position control instruction to the uncoster 80 associated with the instruction device 6 possessed by the instructor who requested the unco loading instruction. Do.
In response to the position control command, the cylindrical accommodating portion moving mechanism 117 positions the upper end inlet port 79 of the uncosted picker 80 directly below the undeco-led portion 99 of the unco-dropped portion 77. Then, the unco conveying device that has received the conveying operation command conveys the unco 12 to the unco-dropping portion 77 one by one, and the unco 12 is supplied to the uncoster 80.
Furthermore, the control device 5 having received the unco loading instruction drives the water injection device 145 to supply mist toward the downstream side of the loading machine 7 and the loading hose 8, and the pipe line of the downstream inclined pipe 141 By forming a liquid film on the inner surface and the inner surface of the loading hose 8, the lubricity of the inner surface of the pipeline of the downstream inclined tube 141 and the inner surface of the loading hose 8 and the outer surface of the anvil 12 is improved, and the anvil 12 is downstream. The friction when dropping the inner surface of the side slope pipe 141 and the inner surface of the loading hose 8 is reduced, and the generation of static electricity can be prevented.
The uncoster 80 is located just below the ancho dropping portion 77 and can receive the anko 12 and can drop the anko 12 onto the anchoshot 82 located just above the ankochute 82. It is set at the Anko dropping position, and is usually located at the Anko dropping position. That is, the Anko dropping position is the initial position.

Note that the first indicator 6 associated with one pumping device 4, that is, the first uncoster 80 that sends the feed 12 to the first pumping device 4 and the first pumping device 4, and the other pumping A second indicating device 6 is associated with the device 4, ie, the second pumping device 4 and the second un-coster 80 for sending the feed 12 to the second pumping device 4.

When the control device 5 outputs a position control command to the cylindrical container moving mechanism 117 and the bottom support plate moving mechanism 118 of the uncoster 80, the cylindrical container moving mechanism 117 sets the upper inlet port 79 of the uncoster 80. The bottom receiving plate moving mechanism 118 locates the bottom receiving portion 116 at the center side in the cylindrical housing portion 115 and positions the bottom 12 in the cylindrical housing portion 115. Are set to a state in which only two can be received, for example. Then, the ancho drop detection sensor 95 outputs to the control device 5 a detection signal that detects the falling of the two anchos 12, and the ancho monitoring means 160 in the control device 5 that receives the two detection signals receives the bottom support plate. By sending a position control command to the moving mechanism 118, the bottom receiving plate moving mechanism 118 causes the bottom receiving portion 116 to be positioned directly below the lower end discharge port 81 of the cylindrical housing portion 115, and the hook 12 is placed in the cylindrical housing portion 115. Set to a state where it is possible to receive four. Then, a detection signal when the lower hook detection sensor 120 detects the anchor 12 positioned at the lowermost position in the cylindrical housing 115, and the top anchor echo in which the upper anchor detection sensor 119 is housed in the cylindrical housing 115 12. An unco monitoring means 160 that has received the detection signal that has detected 12 outputs a bottom receiving part opening command to the cylindrical housing moving mechanism 117, and the cylindrical housing moving mechanism 117 that has received the position control 80 is returned to the initial position, the bottom receiving plate moving mechanism 118 moves the bottom receiving portion 116 out of the position just below the lower end discharge port 81 of the cylindrical storage portion 115, whereby the bottom receiving plate is accommodated in the cylindrical storage portion 115. The predetermined number of four anchos 12 that have been dropped fall on the anchoshot 82.
At this time, a liquid film is formed on the inner surface of the pipe line of the downstream inclined pipe 141 and the inner surface of the loading hose 8 by the mist generated by diffusion of the water injected from the water injection device 145 by compressed air. The lubricity of the inner surface of the downstream side inclined pipe 141 and the inner surface of the loading hose 8 and the outer surface of the anvil 12 is improved, and the anvil 12 dropped from the uncoster 80 to the anchoshot 82 smoothly in the loading hose 8 Supplied. Further, the friction when the annulus 12 falls on the inner surface of the downstream inclined pipe 141 and the inner surface of the loading hose 8 is reduced, and the generation of static electricity can be prevented.

Thereafter, the control device 5 that recognizes that the bottom receiving plate moving mechanism 118 has positioned the bottom receiving portion 116 directly below the lower end discharge port 81 of the cylindrical storage portion 115 instructs the pumping air supply mechanism 142 to perform the pumping operation. As a result, a predetermined number of anvils 12 supplied to the loading hose 8 are pressed by the pressure of the air flow and are pumped to the loading hole H and loaded into the loading hole H.
After instructing the pumping air supply mechanism 142 to perform the pumping operation, the control device 5 confirms that the loading operation of the predetermined number of the anchors 12 is completed. In addition, the end sound that is output after the control device 5 confirms the completion of the pumping operation to the pumping air supply mechanism 142 or the output display on the display outside the figure, or the annko 12 An operator or a supporter can confirm by a response etc. when passing through the inside of the loading pipe 9.
