A large amount of paper P can be loaded on the paper loading plate BP, and the paper loading plate BP loaded with the paper P rises to a predetermined height and is sent out in order from the highest paper P by the nager roll 231. It is designed to be used.
The paper P sent out by the nager roll 231 is conveyed toward the image forming unit 100 while being separated by the feed roll 232 and the retard roll 241.

A holding device 300 is detachably arranged on the paper loading plate BP. The holding device 300 is placed on the paper loading plate BP by positioning the width direction and the feeding direction by the side guide SG and the end guide EG as the positioning means of the paper P.
A paper presence / absence sensor SNR as an example of the detecting means is arranged on the side of the nager roll 231 above the holding device 300. The paper presence / absence sensor SNR contacts the uppermost paper P of the loaded paper P and detects the presence / absence of the paper P on the paper loading plate BP or the holding device 300.

(2.2) Holding device As shown in FIG. 3, the holding device 300 has a space R on a base 310 having a rectangular and thin plate shape as a whole.
It is composed of a holding portion 320 as a holding means for forming the height of the paper and a supporting portion 330 as a supporting means arranged in the holding portion 320, and the thick side of the paper P on the paper loading plate BP is the paper loading plate. The BP and the najar roll 231 bend in the direction of gravity (see the arrow in FIG. 3) to form a loadable space R.

The material of the base 310 is not particularly limited, but in the present embodiment, as an example, the base 310 is formed by cutting out a lightweight plastic cardboard having a certain strength and a thickness of about 5 mm into a predetermined rectangular shape. There is.
As shown in FIGS. 3 and 4, the holding portion 320 is formed so that the central portion in the width direction of the paper P extends in the feeding direction of the paper P and the rear end TE side is higher than the front end LE side in the feeding direction. Has been done. The material of the holding portion 320 is not particularly limited, but in the present embodiment, a foamed polyethylene resin having a foaming ratio of about 20 to 30 times is preferable in that it is lightweight and has a certain shape retention property.

The support portion 330 is arranged on the holding portion 320 at a position behind the position where the nager roll 231 contacts the uppermost paper P on the front end LE side in the feeding direction of the holding portion 320 and does not collide with the paper presence sensor SNR. ing. Specifically, the support portion 330 is a plate-shaped member that extends in a direction in which the entire support portion 330 intersects the delivery direction, and one end side thereof protrudes from the holding portion 320 to form a width direction that intersects with the delivery direction of the space R. ..

Further, the support portion 330 is flexible, and when a predetermined amount of paper P as a load is loaded on the holding device 300, the support portion 330 comes into contact with the bottom surface of the loaded paper P and gravity in the space R. It bends in the direction (−Z direction) and acts to reduce the height difference of the upper surface of the loaded paper P. In the present embodiment, the flexible support portion 330 is formed of an ABS resin plate having a thickness of 1 mm as an example, but the flexible plate-shaped member is a thin metal plate. You may.

(2.3) Operation of the holding device FIG. 5 is a diagram for explaining the loading shape when the square 2 envelopes P having different thicknesses in the width direction are loaded, and FIG. 6 is a diagram for explaining the loading shape when the transparent pockets P having different thicknesses in the width direction are loaded. FIG. 7 is a diagram showing the loading shape of the square 2 envelope P loaded on the holding device 300, and FIG. 8 is a diagram showing the loading shape of the transparent pocket P loaded on the holding device 300. 9 (a) is a view showing a side intersecting the delivery direction of the transport device loaded with square 2 envelopes via the holding device 300, and FIG. 9 (b) is a transport device loaded with square 2 envelopes via the holding device 300. 14 (a) is a diagram showing the side of the square 2 envelope along the delivery direction, FIG. 14 (a) is a diagram showing the side intersecting the delivery direction of the transport device in which the square 2 envelope is loaded on the paper loading plate PB, and FIG. It is a figure which shows the side along the delivery direction of the transport device loaded on a plate PB.

As shown in FIG. 5, for example, the square 2 envelope has a overlapped adhesive portion P2 located on one side in the width direction intersecting the front-rear direction, which is the transport direction, in addition to the folded adhesive portion P1 on the bottom side. There is.
Further, as shown in FIG. 6, the transparent pocket has a stacking bag portion P3 located on one side in the width direction intersecting the front-rear direction which is the transport direction.

When the square 2 envelopes P, which are examples of the conveyed objects having different thicknesses in the width direction, are stacked and loaded, as shown in FIG. 5, the front end LE side on which the relatively thick folded-back adhesive portions P1 are stacked becomes higher. At the same time, the side S1 on which the relatively thick laminated adhesive portions P2 are stacked becomes higher, and when the sheets are loaded on the paper loading plate PB, a height difference occurs on the upper surface of the uppermost paper P.
Further, even when the transparent pocket P is loaded, as shown in FIG. 6, the side S1 on which the relatively thick overlapping bag portions P3 are stacked becomes higher, and when the transparent pocket P is loaded on the paper loading plate PB, the highest position is obtained. A height difference occurs on the upper surface of the paper P of.

When a height difference occurs on the upper surface of the uppermost paper P, as shown in FIG. 14A, the upper surface of the paper P comes into contact with the nager roll 231 when the paper loading plate PB rises to a predetermined height. Previously, there was a risk of contacting a part of the main body 210 of the transport device 200. In addition, the najar roll 231 cannot evenly contact the upper surface of the paper P, which may cause non-feeding or skewing.

In the transport device 200 according to the present embodiment, when the square 2 envelope P and the transparent pocket P are loaded on the paper loading plate PB and transported as an example of the transported objects having different thicknesses in the width direction, the paper loading plate PB By placing the holding device 300 on the holding device 300 and loading the paper P through the holding device 300, the height difference between the thick side and the thin side of the transported object is reduced, and the posture at the time of feeding is reduced. It is flat.

As shown in FIG. 7A, the side S1 side on which the thick overlapping adhesive portions P2 of the square 2 envelope P are stacked is set to the space R side formed by the holding portion 320 and the supporting portion 330 of the holding device 300 and loaded. Then, the support portion 330 that comes into contact with the bottom surface of the paper P and supports the paper P bends in the gravity direction (-Z direction: see the arrow in the figure) due to the weight of the square 2 envelope P on which the paper P is loaded, and is at least the highest. The height difference in the width direction of the square 2 envelope P is small.

Further, as shown in FIG. 7B, in the feeding direction of the paper P, the front end portion LE side on which the thick folded-back adhesive portions P1 are stacked is set to the side where the height of the holding portion 320 is low, and the paper P is loaded at least at the maximum. The height difference in the delivery direction of the upper square 2 envelope P is also reduced. As a result, even when the square 2 envelope P having the thick folded-back adhesive portion P1 and the thick overlapping adhesive portion P2 is loaded, the height difference between the thick side and the thin side of the square 2 envelope P is small. Then, the posture when the envelope roll 231 is contacted and sent out can be flattened.

As shown in FIG. 8A, even when the transparent pocket P is loaded, the space R formed by the holding portion 320 and the supporting portion 330 of the holding device 300 on the side S1 side on which the thick overlapping bag portions P3 are stacked. By loading on the side, the support portion 330 that contacts the bottom surface of the paper P and supports the paper P bends in the direction of gravity due to the weight of the loaded transparent pocket P, and at least the width of the uppermost transparent pocket P. The height difference in the direction is small.
Further, as shown in FIG. 8B, there is no difference in thickness in the feeding direction of the paper P, but at least the topmost transparent pocket is on the side where the height of the holding portion 320 is low (see arrow L in the figure). The height difference in the delivery direction of P is small.

Further, on the rear end TE side of the paper P in the feeding direction, the central portion of the holding portion 320 is formed so as to be higher than the front end LE side in the feeding direction, so that FIGS. As shown in c), the paper P is in a medium-high posture in the width direction intersecting the feeding direction, and the holding of the paper P on the holding device 300 is stable.

In this way, when the paper P having a different thickness in the width direction intersecting the feeding direction of the paper P is loaded and conveyed, the holding device 300 is placed on the paper loading plate BP as shown in FIG. Then, by loading the paper P on the holding device 300, the paper P is sent out by the nager roll 231 in a state where the height difference between the thick side side and the thin side side is reduced. As a result, non-feeding and skewing in sending can be suppressed.

"Modification example"
10 (a) is a plan view of the holding device 300A according to the modified example, (b) is a left side view, (c) is a right side view, (d) is a front view, and FIG. 11 is a holding device 300A according to the modified example. 12 is a right side view showing another example of the holding device 300A according to the modified example, FIG. 13 is a right side view showing another example of the holding device 300A according to the modified example, and FIG. 13 is a corner 2 loaded on the holding device 300A according to the modified example. It is a figure which shows the loading shape of the envelope P.
As shown in FIG. 10, the holding device 300A according to the modified example has a holding portion 320 forming the height of the space R on the base 310, a support portion 330 arranged in the holding portion 320, and a support portion 330. It is composed of an elastic body 340 that comes into contact with the support portion 330 and supports the support portion 330 when the is bent.

As shown in FIG. 10, the elastic body 340 has a first elastic body 341 having a first height H1 in the projecting direction of the support portion 330 and a second height H2 lower than the first height H1. It is composed of a second elastic body 342 having.

In the elastic body 340, the first elastic body 341 comes into contact with the support portion 330 when the support portion 330 bends in the space R, and the first elastic body 341 and the second elastic body 341 and the second elastic body 340 when the support portion 330 further bends. The elastic body 342 comes into contact with the support portion 330 and acts to support the loaded paper P in the space R. Therefore, the elastic body 340 is not particularly limited as long as it has elasticity such as a foamed sponge body and a coil spring, but in the present embodiment, EPDM or NBR foamed rubber sponge is used. When the elastic body 340 is a foam rubber sponge, the contact with the bottom surface of the support portion 330 is a surface contact having a certain area, and the bent state of the support portion 330 is more likely to be stabilized than the coil spring.

The elastic modulus of the foam rubber sponge can be appropriately selected according to the maximum load capacity of the paper P to be loaded. In particular, the elastic body 340 may be a foam rubber sponge in which the first elastic body 341 and the second elastic body 342 have different elastic moduli.
For example, when a small amount of paper P is loaded by setting the elastic modulus of the first elastic body 341 to be relatively low and the elastic modulus of the second elastic body 342 to be higher than that of the first elastic body, The first elastic body 341 is compressed to support the support portion 330, and when a large amount of paper P is loaded, the first elastic body 341 and the second elastic body 342 are compressed to support the support portion 330. As a result, the height difference of the top-level paper P can be reduced according to the load capacity of the loaded paper P.

As shown in FIG. 11, the elastic body 340 can be arranged by selecting the position of the support portion 330 in the protruding direction on the base 310. For example, as shown in FIG. 11A, when the protruding support portion 330 is arranged on the base end portion 330a side, the amount of deflection of the tip portion 330b of the support portion 330 can be increased, and the thickness difference in the width direction can be increased. When a large paper P is loaded, the height difference of the top paper P can be reduced.
Further, as shown in FIG. 11B, when the protruding support portion 330 is arranged on the tip end portion 330b side away from the base end portion 330a, even when a large amount of paper P having a large basis weight is loaded, the top position is reached. The height difference of the paper P can be reduced.

Further, in the holding device 300A, when the support portion 330 is bent in the space R, the support portion 330 is supported by the elastic body 340. Therefore, the support portion 330 is a plate-shaped member as a whole. If so, the material itself does not need to be flexible, and as shown in FIG. 12, it has a rotation fulcrum 331 and the tip 330b can move in the space in the gravity direction (−Z direction) (FIG. 12 (FIG. 12). b) The configuration may be (see the middle arrow).

When a square 2 envelope P or a transparent pocket P having different thicknesses in the width direction is loaded on the holding device 300A configured as described above, as shown in FIG. 13A, when the loaded paper P is a small amount, it is supported. The portion 330 is supported with almost no bending, and the uppermost paper P is supported with almost no height difference in the width direction.
When the amount of the loaded paper P reaches a certain amount, as shown in FIG. 13B, the support portion 330 bends in the gravity direction (−Z direction) due to the weight of the loaded paper P, and the first elastic body The 341 is positioned in a compressed state in balance with the weight of the paper P. As a result, at least the height difference in the width direction of the topmost paper P is reduced.

When a larger amount of paper P is loaded on the holding device 300A, as shown in FIG. 13C, the support portion 330 bends in the gravity direction (−Z direction) due to the weight of the loaded paper P. The first elastic body 341 is compressed and supported, and is positioned in balance with the weight of the paper P in a state of being supported by the second elastic body. As a result, even when a large number of square 2 envelopes P and transparent pockets P having different thicknesses in the width direction are loaded, the height difference of the topmost paper P in the width direction is reduced.
As a result, when a large number of square 2 envelopes P and transparent pockets P having different thicknesses in the width direction are loaded and transported, non-feeding and skewing in feeding can be suppressed.

In the present embodiment, as an example of the transported object, a transport device for transporting papers having different thicknesses in the width direction, such as square 2 envelopes and transparent pockets, in a state of being stacked and loaded, has been described. It can be applied not only to the recording medium that passes through the image forming apparatus, but also to the conveying device that conveys conveyed objects having different thicknesses in the width direction, such as a package that internally accommodates and packages a metal plate, pharmaceuticals, and confectionery. it can.
