And a thickness detecting means for detecting a thickness of the conveyed material in the conveying path, wherein the thickness detecting means detects the thickness of the conveyed material in the conveying path. A moving member that returns after moving, and at the time of the returning operation of the moving member, connects the moving member and the support member, and the returning operation of the moving member expands the accommodation volume of the supporting member by the returning operation of the moving member. And a connecting means for moving in the direction of movement.

[Operation] When the detecting means detects the thickness of the conveyed object on the conveying path, the moving member moves according to the detection result of the detecting means, and then returns. At the time of the returning operation of the moving member, the connecting means connects the moving member and the supporting member, and moves the supporting member in the direction of increasing the storage volume of the storage portion by the returning operation of the moving member.

Next, an embodiment of the present invention will be described with reference to the drawings.

<Structure> As shown in FIGS. 1 and 2, the apparatus 10 for storing a transported object includes a transport unit 20 and a storage unit 50.

As shown in FIG. 3, the transport section 20 includes a bracket 21 having a guide elongated hole 21a guided by guide pins 22a and 22b fixed to a frame (not shown) above the transport path P. It is always biased downward by 23.

The bracket 21 is provided with an engagement pin 24 for engaging with a drive member 35 described below to limit the amount of descent.

A shaft 25 is fixed to the bracket 21.
A pinching roller 27 constituting a pinching means 26 is pivotally supported by 25. Below the sandwiching roller 27, a sandwiching receiving roller 28 which also constitutes a sandwiching means.

In the vicinity of the lower end of the drive member 35, an engagement square hole 35c which is engaged with the engagement pin 33 of the swing first lever 31 and is a component of the transmission means is formed.

A detection sensor 34 for detecting the transported object B is provided between the sandwiching means 26 and the driving member 35 with the transport path interposed therebetween. When the detection sensor 34 does not detect the transport object B on the transport path P, the driving member 35 is pushed up to its upper limit position by the thickness detection driving motor 38 as shown in FIG. Is occupied at a position separated from the sandwiching receiving roller 28 by a predetermined distance S.

Further, the thickness detection drive motor 38 is configured to be able to descend by the predetermined interval S0 in the descending direction regardless of the presence or absence of the conveyed object.

Therefore, assuming now that the thickness of the transported object B is b, the sandwiching roller 27 is minimal (S
−b) must descend. However, the driving member
35 is further moved by S- (Sb) = b.

On the other hand, as shown in the drawing, an engagement notch for engaging with an engagement pin 42 of the second swing lever 40 described below is provided at one end of the first swing lever.
31a is provided.

The swinging second lever 40, which constitutes the transmission means, is pivotally supported at substantially the center of its length by a swinging shaft 41, and has an engagement notch at the other end.
40a is provided.

As shown in FIG. 3, the storage section 50 is a case entrance of the case 51.
A moving member 52 that receives the movement of the transport unit 20 is provided on the 51a side.

The moving member 52 is guided vertically by a guide pin 53a, 53b in a vertically elongated guide hole 52a formed in a vertically long shape, and is engaged with the engagement notch 40a of the swing second lever 40 near the lower end thereof. An engagement pin 54 for transmitting a vertical movement is implanted.

A gate roller 56 is pivotally supported on the shaft 55 at the upper part of the moving member 52. The gate roller 56 is supported by a shaft 57 provided on the case 51 with the gate receiving roller 58 sandwiching the conveyance path P. I have. The gate receiving roller 58 is driven by a drive motor (not shown) similarly to the pinch receiving roller 28.

As shown in the drawing, a coupling gear described later is provided on one side of the moving member 52.
A rack 52b meshing with 61 is engraved.

As shown in FIG. 2, a support member 60 is provided inside the case 51 for receiving a conveyed object guided by a guide shaft 59 erected in a vertical direction, and a rack 52 of a moving member 52 is provided at one end.
b, a coupling gear (connection means) 61 rotatable in one direction (clockwise in the figure) and a locking gear 64 of a locking means 62 at the other end are also rotatable in one direction (counterclockwise). Have been.

The locking means 62 is a fixed rack member fixed to the case 51.
It comprises a fixed rack 63a engraved on 63 and a locking gear 64.

Further, as shown in the drawing, the support member 60 is constantly urged upward by a tension spring (biasing means) 65, that is, in a direction to reduce the storage volume in the case 51.

<Operation> Next, the operation will be described.

Before the transported object B is detected by the detection sensor 34, the driving member 35 is at its uppermost position as shown in FIG.
Engages with the engagement pin 24 of the bracket 21 to push the bracket 21 to the uppermost position against the urging spring 23.

Since the bracket 21 and the sandwiching arm 29 are connected at the shaft 25, the sandwiching arm 29 is also lifted to the uppermost position, and the sandwiching roller 27 faces the sandwiching receiving roller 28 at a predetermined interval S as shown in FIG. doing.

When the transported object B is sent to the transport path P and is detected by the detection sensor 34, the thickness detection drive motor 38
Starts, the intermediate gear 37 rotates counterclockwise in the figure, and moves the driving member 35 meshing with the intermediate gear 37 downward.

With the downward movement of the driving member 35, the bracket 21 pressed by the urging spring 23 also moves downward, and the pinching arm 29
At the same time, the sandwiching roller 27 is moved downward. By moving at least (S−b), the nipping roller 27 and the nipping receiving roller 28 are moved as shown in FIG.
Is sandwiched in between.

Even in the above state, the drive motor 38 continues to drive.

Even if the driving member 35 continues to descend, the nipping arm 29 stops descending because the nipping roller 27 is nipping the conveyed object B.

Eventually, the square hole 35c for engagement of the driving member 35 engages with the engagement pin 33 of the swinging first lever 31 of the transmission means and pushes it down. As shown in FIG. To rotate. By this rotation, the engagement notch 31a of the first swinging lever 31 is also turned to the second swinging lever 40 as a transmission means.
And the second pivoting lever 40 is pivoted to the pivot shaft.
Rotate counterclockwise around 41.

By the swing of the swing second lever 40, the engagement notch 40a pushes up the moving member 52 of the storage section 50 upward. Then, the gate roller 56 rises and a gate interval substantially equal to the thickness b of the transported object B is provided between the gate roller 56 and the gate receiving roller 58.

When the moving member 52 rises, the coupling roller 61 rotates clockwise as shown in FIG. 6 (b). However, the locking roller 64 does not rotate, and prevents the support member 60 from rising.

Since the amount of movement of the driving member 35 after sandwiching the object B is equal to the thickness b of the object B as described above, the engaging square hole 35c and the engaging pin 33 should normally be tightly connected. Although it should be matched, the length of the lever from the position of the engagement pin 33 to the engagement pin 42 of the swinging second lever 40 is considered, and the amount of movement at the engagement pin 42 is just equal to the thickness b. Or, it is configured to be slightly smaller.

Even during the above operation, the transported object B advances along the transport path P and is stored on the support member 60 from the case entrance 51a of the storage section 50 through the space between the gate roller 56 and the gate receiving roller 58. At this time, the gate receiving roller 58 is driven by a drive motor (not shown).

On the other hand, when the rear end of the transported object B passes the detection sensor 34,
The thickness detection drive motor 38 immediately starts reverse rotation by the signal. Therefore, the driving member 35 moves up, pushes up the bracket 21 and raises the sandwiching arm 29, thereby pulling up the sandwiching roller 27 to a predetermined position.

By the above-mentioned lifting operation, the first swing lever 31 also rotates counterclockwise, and the engagement with the second swing lever 40 is released.

Then, when the transported object B passes through the gate roller 56, the moving member 52 descends. At this time, since the initial rising amount of the moving member 52 corresponds to the thickness b of the transported object B, the descending amount also corresponds to the thickness b of the transported object B. .

At this time, as shown in FIG. 6 (c), since the coupling gear 61 as the coupling means cannot rotate counterclockwise,
52 while being connected to the rack 52b of the
The one supporting member 60 which is pivotally supported is pushed down by the thickness b of the conveyed object B.

The support member 60 pushed down by the thickness b of the conveyed object B is constantly pulled upward by the tension spring 65, but the locking gear 64 supported at the other end of the support member 60 rotates clockwise. Therefore, the support member 60 is stopped at the position without rotating while being engaged with the fixed side rack 63a of the fixed rack member 63.

FIG. 6 (a) shows the state before the operation, and FIG. 6 (b)
FIG. 7 is an explanatory view of the operation of the moving member 52 while the moving member 52 is being lifted. In this case, the supporting member 60
Thus, while stopping at the initial position, the coupling gear 61 rotates clockwise to allow the moving member 52 to rise.

<Effects of Embodiment> According to this embodiment, the thickness b of the conveyed object B sent along the conveying path P is detected by the sandwiching means 26, and the moving member 52 moves via the transmitting means. (At this time, the coupling roller 61 rotates.) After accommodating the transported object B with an interval between the rollers 56 and 58, when the moving member 52 returns, the rotation of the coupling roller 61 is locked. At the same time, the coupling roller 61 also moves down. Therefore, the support member 60 to which the coupling roller 61 is attached is also lowered.

Therefore, since the support member 60 always moves in accordance with the thickness b of the transported object B even for the transported object B having various thicknesses, it is possible to secure a storage volume corresponding to the thickness of the transported object B, and furthermore, to perform stepping. Since an expensive actuator such as a motor is not used, it can be manufactured at low cost, and is not limited to a conveyed object having a constant thickness unlike an apparatus using a ratchet mechanism.

In addition, since the locking roller 64 provided with the one-way rotation clutch that meshes with the fixed rack member 63 is attached to the support member 60, the support member at the time of the ascent operation of the moving member 52 as shown in FIGS. A rise of 60 can be prevented with a simple configuration.

<Modifications> The present invention is not limited to the above embodiment, and for example, the following modifications are possible.

(1) Although the engagement between the moving member 52 and the coupling gear 61 and the engagement between the fixed rack member 63 and the locking gear 64 are performed by the rack and the gear, a high friction coefficient material such as a plate member and a rubber roller is used. Friction engagement can also be used.

(2) The accommodation section is not limited to the one in which the supporting member 60 moves in the vertical direction, and the supporting member may be moved in the horizontal direction, and the accommodation volume may be increased in the horizontal direction so that the transported article stands. . In this case, it is necessary to provide a pressing means for pressing the conveyed object toward the support member and an urging means for constantly urging the gate roller in the closing direction.

(3) Although the connecting roller 61 interposed with a one-way rotating clutch is used as the connecting means, the moving member 52 and the supporting member 60 may be connected by turning on / off a solenoid.

(4) The sandwiching means is not limited to the sandwiching roller as in the above embodiment, but may be a plate or the like.

(5) The thickness detecting means does not use the sandwiching means as in the above-described embodiment, but uses a thickness detecting lever 70 as shown in FIG.
And the swing angle is detected by the encoder 71 or the like.
The holding interval of the transported object B may be set by an electric interval setting unit.

(6) In the above-described embodiment, the gears 61 and 64 are attached to the support member 60, and the moving member 52 and the fixed rack member 63 are provided as members that mesh with the gears 61 and 64. Two gears meshing with the member may be provided so as to move together with the roller 56 (like the moving member 52), and may be provided so as not to move (like the fixed rack member 63).

[Effects of the Invention] According to the present invention, a storage unit that stores a transported object that has been transported along a transport path supports the stored transported object and moves in a direction to increase the storage volume according to the storage amount of the transported object. In a device for storing a conveyed object provided with a support member, a thickness detecting means for detecting a thickness of the conveyed material on a conveying path, a moving member that moves in accordance with a detection result of the detecting means, and then returns, A connecting means is provided for connecting the moving member and the support member during the returning operation of the member, and for moving the supporting member in the direction of increasing the storage volume of the storage portion by the returning operation of the moving member. When the thickness of the object is detected by the detecting means, the moving member moves according to the detection result of the detecting means, and when the moving member returns thereafter, the connecting means connects the moving member and the supporting member, When the moving member returns, the support member For moving in a direction to increase the volume capacity,
The support member can be moved in accordance with the thickness of the conveyed object, and a conveyed object storage device capable of securing a storage volume according to the thickness of the conveyed object can be obtained.
