  Hereinafter, the present invention will be described in detail through embodiments, but the following embodiments do not limit the invention according to the claims, and all combinations of features described in the embodiments are included. It is not necessarily essential for the solution of the invention.

FIG. 1 is a diagram illustrating a configuration of a shooter 10 according to the present embodiment.
The shooter 10 includes a shooter body 11 having a bowl shape having a semicircular cross section perpendicular to the length direction, and an inclination mechanism 12 for inclining the shooter body 11.
Here, the length direction of the shooter body 11 is defined as the x direction, the width direction is defined as the y direction, and the vertical direction as the drop direction is defined as the z direction. The x direction is the front-rear direction and the y direction is the left-right direction.
The tilt mechanism 12 has a rotation support member 13 that has an upper portion attached to substantially the center of the outer peripheral side surface 11a of the shooter body 11 and protrudes downward, a pin 14 provided at the lower end of the rotation support member 13, and one end thereof. A crank mechanism is provided that includes a crank arm 15 attached to the pin 14 and an actuator 16 that includes a rod 16a coupled to the other end of the crank arm 15 and that expands and contracts the rod 16a in the length direction of the shooter body 11. Reference numeral 17 denotes an auxiliary pin provided on the opposite side of the outer peripheral side surface 11a of the shooter main body 11 from the side on which the pin 14 is provided. Thus, the shooter body 11 can be smoothly tilted.
In this example, as the actuator 16, an air cylinder device including a cylinder 16b, a piston 16c sliding in the cylinder 16b, and a rod 16a having one end attached to the piston 16c is used. In place of the air cylinder device, a hydraulic cylinder device may be used. Further, as a cylinder device, a cylinder device having a two-stage stroke can be used in order to cope with three positions of horizontal, + inclination, and −inclination.

The pin 14 is attached so as to protrude from the lower side of the rotation support member 13 in the y direction which is the width direction of the shooter body 11. Therefore, the rotation support member 13 can be rotated via the crank arm 15 by extending the rod 16a.
As a result, the shooter body 11 rotates about the pin 14 so that when one end in the length direction of the shooter body 11 is on the upper side with respect to the horizontal plane, the other end is on the lower side and one end is on the lower side. Rotate so that the other end is on the upper side. That is, since the shooter body 11 can be rotated clockwise and counterclockwise in the zx plane that is a vertical plane including the length direction of the shooter body 11, the shooter body 11 can be rotated in two different directions. Can be tilted. It is assumed that the other end of the pin 14 and the other end of the auxiliary pin 17 are rotatably attached to a shooter holding member (fixed portion) (not shown).
For example, as shown in FIG. 2A, when the actuator 16 is operated to contract the rod 16a, the shooter body 11 is inclined in the extending direction of the rod 16a (hereinafter referred to as the front side). Therefore, the product 1 that has fallen into the recess (inner surface 11 b) of the shooter body 11 can be dropped to the front side of the shooter body 11. On the other hand, as shown in FIG. 2B, when the rod 16a is extended, the shooter body 11 is inclined in the direction opposite to the extension direction of the rod 16a (hereinafter referred to as the rear side). The dropped item 1 can be dropped to the rear side of the shooter body 11.

Next, the transfer system of the present invention will be described.
In this example, a case will be described in which a product (hereinafter referred to as a powder pack product) in which a powder such as an additive is packed with a thin film is transferred.
As shown in FIG. 3, the transfer system 20 of this example includes a mounting unit 20 </ b> A, a transport unit 20 </ b> B, a loading unit 20 </ b> C, and a recovery unit 20 </ b> D, and transports the powder pack product 30 mounted on the base 21. It is conveyed by the conveyor 22 and transferred to the loading pallet 23. The empty base 21 is collected by the collection conveyor 24.

As shown in FIG. 4, the base 21 includes two flat plates 21P. The two flat plates 21P are respectively a fixed plate 21m, a lid portion 21n attached to the fixed plate 21m by a hinge or the like so as to be rotatable downward, and a back surface side (powder of the support plate 21m). An opening / closing mechanism 21K that opens and closes the lid portion 21n is provided on the side opposite to the side on which the pack product 30 is mounted.
As the opening / closing mechanism 21K, for example, a linear actuator including a cylinder 21p and a rod 21q connected to a piston (not shown) in the cylinder 21p, and a lower end of the lid 21n provided at the tip of the rod 21q are supported. An opening / closing mechanism including the support member 21r can be used.
In a state where the rod 21q is extended, the support member 21r supports the lid portion 21n from the lower side and closes the lid portion 21n. On the other hand, when the rod 21q is contracted, the lid 21n is not supported by the support member 21r, so the lid 21n opens downward. Therefore, the powder pack product 30 mounted on the base 21 can be dropped downward.

First, the powder pack product 30 to be newly transferred is mounted on the empty base 21 by the mounting unit 20A.
The base 21 on which the powder pack product 30 is mounted is conveyed to the loading unit 20C by the conveyance conveyor 22 of the conveyance unit 20B.
As shown in FIG. 5, the loading unit 20 </ b> C is provided with a base installation table 40, and a loading pallet for arranging and storing the powder pack products 30 below the base installation table 40. 23 is set.
In addition, the loading pallet 23 before loading is stacked on one side of the base installation table 40, and a predetermined number (for example, 4 rows in the front-rear direction × 4 rows in the left-right direction = 16 packs) is stacked on the other side. ) And the loaded pallet 23 after loading, in which the powder pack products 30 are stored in an aligned manner, are stacked.

The base installation base 40 has two rails 41 for supporting the opposite side of the lid 21n of the fixed slope 21m of the two flat plates 21P constituting the base 21, and this rail 41 is used as the base installation base. Rail moving means 42 for moving to a predetermined position of 40. As the rail moving means 42, for example, a wire type traction device that pulls the rail 41 with a wire 42 </ b> W can be used.
The base 21 transported by the transport conveyor 22 moves on the rail 41 of the base installation base 40 and stops. The rail moving means 42 moves the rail 41 in the direction opposite to the conveying conveyor 22 and stops when the base 21 comes directly above the loading pallet 23.
Then, on the base installation base 40, by reducing the rod 21q of the opening / closing mechanism 21K, the lid portions 21n and 21n are opened downward, and the powder pack product 30 on the base 21 is dropped onto the loading pallet 23. .
If the height of the rail 41 is the same as or slightly lower than the height of the transport conveyor 22, the base 21 can be smoothly moved from the transport conveyor 22 to the base installation base 40.

In this example, the shooter 10 is installed between the base installation base 40 and the loading pallet 23 so that the falling direction of the powder pack product 30 dropped from the base 21 can be switched between two directions. Therefore, the powder pack product 30 can be dropped and aligned at two locations before and after the loading pallet 23 without moving the loading pallet 23 or with a small amount of movement.
FIGS. 6A and 6B are diagrams showing a method for transferring the powder pack products 30A and 30B.
First, the powder pack product 30 </ b> A that is mounted on the base 21 and falls first is transferred to the loading pallet 23. At this time, as shown in FIG. 2A, the powder pack product 30 </ b> A is dropped to a predetermined position 23 </ b> A in front of the loading pallet 23 by tilting the shooter 10 forward. After dropping the powder pack product 30A, the rod 21q of the opening / closing mechanism 21K is extended to close the lid portions 21n and 21n, and then the rail 41 is further moved in the direction opposite to the conveying conveyor 22. As a result, the empty base 21A is sent to the collection conveyor 24 of the collection unit 20D.
If the height of the collection conveyor 24 is slightly lower than that of the rail 41, the base 21 that has been emptied can be smoothly moved from the base installation base 40 to the collection conveyor 24.
Next, when the powder pack product 30B mounted and transported on the base 21B is transferred to the loading pallet 23, the shooter 10 is inclined backward as shown in FIG. The packed product 30B is dropped to a predetermined position 23B behind the loading pallet 23. Accordingly, the powder pack products 30A and 30B can be transferred to the predetermined positions 23A and 23B of the loading pallet 23 without moving the position of the loading pallet 23 or the position of the shooter 10 or with a small amount of movement. .
Note that the base 21B is also sent to the recovery conveyor 24 after closing the lid portions 21n and 21n after dropping the powder pack product 30B, similarly to the base 21A.

Further, as shown in FIGS. 7A and 7B, when the powder pack products 30C and 30D are transferred from the bases 21C and 21D to be transported to the loading pallet 23, the loading pallet 23 is moved. The powder pack products 30C and 30D are moved in front of the loading pallet 23 after movement and the two places 23C and 23D after the movement in the same manner as in the case of the base 21A and the base 21B. Can be dropped and aligned.
Next, when the loading in the four rows in the front-rear direction is completed, the loading pallet 23 is moved to the left side by a predetermined distance in advance, and the powder pack product 30 is aligned in the second row in the left-right direction. Store.
By repeating such an operation, the packed pallet 30 can store the powder pack products 30 of 4 rows in the front-rear direction × 4 rows in the left-right direction = 16 packs while being aligned.
The loading pallet 23 storing a predetermined number of powder pack products 30 is stacked on the loading pallet 23 after loading, and a new loading pallet (empty loading pallet) 23 is set at the loading position.

As described above, in this embodiment, the shooter 10 installed between the loading pallet 23 and the base 21 to reduce the falling speed of the powder pack product 30 has a substantially U-shaped cross section perpendicular to the length direction. Formed into a bowl-shaped shooter body 11 and a tilting mechanism 12 that tilts the shooter body 11 to the front side and the rear side in the length direction, and the powder that has fallen into the recess (inner surface 11b) of the shooter body 11 Since the drop direction of the body pack product 30 can be switched between two directions, the powder pack product 30 can be dropped at different positions on the loading pallet 23 without moving the loading pallet 23 or with a small amount of movement. it can. Therefore, the transshipment operation of the powder pack product 30 can be performed in a short time, and the productivity can be improved.
At this time, the tilting mechanism 12 includes a rotation support member 13 attached to substantially the center of the outer peripheral side surface 11 a of the shooter body 11, a pin 14 provided at the lower end of the rotation support member 13, and one end connected to the pin 14. The shooter main body 11 can be made smooth by comprising the attached crank arm 15 and the actuator 16 having the rod 16a connected to the other end of the crank arm 15 and extending the rod 16a in the longitudinal direction of the shooter main body 11. Can be tilted.

In the above-described embodiment, the example in which the powder pack product 30 is transferred from the base 21 to the loading pallet 23 has been described. However, the present invention is not limited to this, and the rubber product and the tire components that are not packed, Alternatively, the present invention can also be applied to a transfer system that needs to load a conveyed article at an accurate position, such as another bag-like object, a lump-like object, or containers. The contents of the powder pack product 30 may be raw materials such as natural rubber and synthetic rubber, or additives and compounding chemicals such as silica powder.
In the above example, the shooter body 11 has a semicircular cross section. However, the present invention is not limited to this, and the surface receiving the powder pack product 30 has a concave smooth curve such as a U shape. I just need it. Further, when the article to be transferred is soft, it is preferable to secure a sufficient width of the shooter body 11 and to make the corner portion of the upper side end face that corresponds to the opening portion into an R shape. Thereby, even if the drop position of the article falling from the conveyor 22 is shifted, the article is not caught on the corner, so that the article can be transferred more quickly.

In the above example, the powder pack products 30A and 30B are dropped at different positions before and after the loading pallet 23, and then the loading pallet 23 is moved forward. However, a device for transferring the shooter 10 is provided, and the shooter 10 may be moved backward.
Further, as the order of arrangement on the loading pallet 23, the front and rear rows may be completed after the left and right rows are completed. Also in this case, what is moved is not limited to the loading pallet 23, and the shooter 10 or both the shooter 10 and the loading pallet 23 may be moved. In any case, if the shooter 10 of the present invention is used, the powder pack product 30 can be dropped at different positions before and after the loading pallet 23 or on the left and right, so that the transfer efficiency can be improved.

  In the above example, the shooter main body 11 is rotated by the tilt mechanism 12 including the crank mechanism. You may make it incline the shooter main body 11 using. Alternatively, the shooter body 11 may be inclined by attaching a rotation shaft extending in the width direction to the shooter body 11 and rotating the rotation shaft directly with a motor.

In the above example, the lid portions 21n and 21n are opened by the opening / closing mechanism 21K using a linear actuator and the powder pack product 30 is dropped onto the shooter 10, but an opening / closing mechanism using an electromagnetic solenoid and a return spring, etc. Other opening / closing mechanisms may be used.
Further, the powder pack product 30 may be dropped onto the shooter 10 using other dropping means such as tilting the base 21.
Further, the powder pack product 30 may be directly gripped and moved directly above the shooter 10 and then dropped.
