Description

The present invention relates to a transfer device for an unexpanded box such as a one-touch box, and more particularly to a transfer device for an unexpanded box that is set in multiple numbers in the same direction like a magazine.

A one-touch box, that is, a box with a one-touch bottom, is a box in which a laid square tube is raised in a quadrangle, that is, the bottom is automatically assembled when the box is raised. For example, it is used for outer boxes of cosmetics.

Conventionally, it has been necessary to transfer the one-touch box as an undeployed box that has been laid down, upstream of a mechanism for raising the one-touch box (expanding it into a tubular shape) or upstream of a line for printing on the surface. At this time, there is a problem in that, when the bundle is fed in the same direction to the downstream side, the bottom portion is folded, so that the bottom portion is easily swollen and the conveying posture is not stable.

In order to solve this, with the bottom side of the unexpanded box facing down, the partition is applied from the top and the partition is moved at the same speed as the transfer belt, and the transfer method in which the partition is always applied and the unexpanded box bundle is A transfer method was adopted in which it rotates and is supported by a V-shaped conveyance path on two sides.

However, the conventional transfer method has a problem in that the instability is still unresolved and it may interfere with the downstream mechanism.

It is characterized by orbiting while standing vertically.

That is, the invention according to claim 3 prevents interference with the delivery destination mechanism of the leading undeployed box located at the most downstream side in the transfer direction, and improves the degree of freedom in line design.

On the same plane is ideologically meant, for example, that the mounting position of the guide pin on the transfer belt is approximately on one plane (horizontal plane), and the guide pin is moving downward at the end. It means not to.

The unexpanded box transfer device according to claim 4 is the unexpanded box transfer device according to any one of claims 1 to 3, wherein the leading unexpanded box is locked at a predetermined position on the most downstream side in the transfer direction. It is characterized in that a locking claw is provided.

That is, the invention according to claim 4 realizes more stable delivery of the leading unexpanded box.

The presence of the locking claws constitutes the leading undeveloped box (the position thereof) is, so to speak, an open surface or a take-out surface.
Further, the locking claw may not be fixed and may move in the transfer direction, for example, and may be extended by a spiral screw in some cases.

The flat object transfer device according to claim 5 is a transfer device for transferring flat objects having the same shape, one side of which expands when they are bundled in the same direction, in a state of standing upright with the expanded side down. A transfer belt for transferring flat objects, and guide pin circling means arranged on both sides of the transfer belt, each set having guide pins of a predetermined length and a plurality of guide pins mounted at least near the transfer belt. The guide pin has a mounting wheel body that moves in a state of standing in the vertical direction, and a revolving roller that circulates by hanging the mounting wheel body.The guide pins on both sides of the transfer belt regulate flat objects and bundle them. It is characterized in that it is provided with a guide circling means which is inserted and transferred to the transfer belt side as it is.

That is, the invention according to claim 5 has a simple structure, and the swelling is regulated in two directions, that is, the traveling direction and the direction intersecting with the traveling direction, while the guide pin is arranged so as not to interfere during taking out for stable transfer. Realize.

The invention according to claim 5 can employ the same configurations as described in claims 1 to 4.

According to the present invention, it is possible to stably transfer undeveloped boxes whose one side is likely to swell when they are bundled.

It is a top view of the transfer apparatus of this invention. It is a side view of the transfer apparatus of this invention. It is sectional drawing (AA sectional drawing) which looked at the transfer apparatus of this invention from the front.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Here, a transfer device for transferring a vertically long one-touch box will be described.
1 is a plan view of the transfer device, FIG. 2 is a side view of the transfer device, and FIG. 3 is a sectional view taken along line AA (a sectional view seen from the front direction). In the figure, the scales of the respective components are not necessarily unified for convenience of description, and some of the components such as the teeth of the sprocket and the undeployed box are omitted.

The one-touch box B is a vertically long box, and the bottom surface is a one-touch type. In the undeployed or collapsed state (this is referred to as an undeployed box HB), the flap forming the bottom surface is folded inside, and the bottom surface is automatically formed when the box is raised. Although a detailed description of forming the bottom surface is omitted, an example of a configuration in which two pairs of two adjacent flaps are bonded to each other in advance and the flap ends are symmetrically engaged with each other as tongues in the raising box can be given. In this way, since the bottom side of the undeployed box HB is folded over, if the bundles are aligned in the same direction, the bottom side is likely to swell and the posture stability of the bundle is poor. In the present embodiment, an explanation will be given on the assumption that the base is a square with a side length of 4 cm and the height is 13 cm.

The transfer device 1 is large and has a placement transfer section 2 for transferring the unexpanded boxes HB in a bundled state like a magazine, and a pin circulation section 3 for pushing the unexpanded boxes HB to the downstream side while maintaining the posture of the unexpanded boxes HB. It is composed of The stacking direction of the bundle of undeployed boxes HB is the traveling direction. It can be said that each undeployed box stands with its surface facing the direction of travel.

The placement transfer unit 2 includes an endless belt 21 and a drive roller 22.
The endless belt 21 is a belt-shaped belt, and is a belt for transferring the bottom side of the undeployed box HB with the bottom side grounded. Here, a rubber belt having an appropriate coefficient of friction is used, and the belt width is narrower than the bottom and is 5 cm.
The length of the loop of the right end belt 21 is not particularly limited, and may be appropriately set depending on the stack amount of the undeployed box HB, the transfer speed, the feeding speed of the bundle, and the like.

The drive roller 22 is a roller for transferring the endless belt 21, and is rotated at a constant speed during driving. This rotation speed can be adjusted appropriately.
It should be noted that the placement transfer unit 2 also includes a terminal roller 23 and a tension roller 24. The end roller 23 has a small diameter so that the pin 31 does not interfere with the next mechanism such as picking up the undeveloped box HB at the top. The tension roller 24 is a roller that gives the endless belt 21 an appropriate amount of tension. The end roller 23 and the tension roller 24 are driven by the drive roller 22 via the endless belt 21. As illustrated, the drive roller 22, the end roller 23, and the tension roller 24 have their axes oriented horizontally.

The pin winding portion 3 is composed of a pin 31, a pin mounting belt 32, a sprocket 33, an auxiliary guide 34, and a locking claw 35, and two sets are provided symmetrically on both sides along the length of the endless belt 21. There is.

The pin 31 is an elongated, non-bending cylindrical rod that is applied to the side surface of the undeployed box HB from below. The pin 31 is inserted and fixed in the pin holder 322 of the pin mounting belt 32. Here, it is made of stainless steel of 3 mmφ×8 cm.

The pin mounting belt 32 is a belt that is stretched around the sprocket 33, and the pin 31 is erected and rotated. In detail, the pin mounting belt 32 is a belt belt having a width of 3 cm (height can be said to be 3 cm from the viewpoint of orientation), and a fitting hole 321 for fitting the teeth of the sprocket 33 is provided inside the belt belt. Are provided in two rows, one above the other.
On the other hand, a pin holder 322 which is a bottomed cylinder is attached to the outside of the pin attachment belt 32 in the band width direction (vertical direction) so that the pin 31 can be attached from above. Moreover, the pin holders 322 are attached at equal intervals. As will be described later, the two sets of phases are aligned at equal intervals, and the transfer posture of the bundle of undeployed boxes HB is maintained.

The sprocket 33 is composed of a drive sprocket 331, an end sprocket 332, and an auxiliary sprocket 333, and has a rotating shaft 336, a rotating shaft 338 (not shown), and a rotating shaft 337, which are vertically attached to each other. As shown, the end sprocket 332 has a smaller diameter than the drive sprocket 331 and the auxiliary sprocket 333.
The drive sprocket 331, the end sprocket 332, and the auxiliary sprocket 333 have the same tooth pitch, and are engaged with the fitting holes 321 to rotate the pin mounting belt 32 via the drive sprocket 331. Here, since the rotating shaft 336 (rotating shaft 337, rotating shaft 338) is oriented in the vertical direction, the group of pins 31 circulates on a predetermined horizontal plane, but at least along the longitudinal direction of the endless belt 21. The sprocket 33 is arranged so that the pin row in the outward path is parallel to the endless belt 21 and is close to the endless belt 21.
The end sprocket 332 has a small diameter so that it does not interfere with the mechanism installed next to the leading undeployed box HB.
Since the pin attachment belt 32 has a width and the pin holder 322 maintains its posture without being bent or twisted by the tension of the sprocket 33, the transfer posture of the pin 31 is also stabilized in the vertical direction.
In this example, the rotation axis of the sprocket 33 is set to the vertical direction, but it may be set to the horizontal direction which is the same direction as the axis of the drive roller 22 depending on the specifications.

The auxiliary guide 34 is an inverted J-shaped plate body when viewed in the traveling direction of the endless belt 21, and is a guide that laterally supports the lower side of the bundle of undeployed boxes HB. In the figure, the pins 31 on the return path side are arranged so as to straddle the sky, but the present invention is not limited to this as long as the undeployed box HB is laterally supported.

The locking claws 35 are arranged on both sides of the most downstream of the endless belt 21 and lock the leading undeployed box HB. Since the pins 31 are not applied to the individual unexpanded boxes HB but are arranged at equal intervals with respect to the bundle, they are provided in order to prevent the leading bundle from being opened and loosened and to maintain the posture. Here, in order to avoid interference with the downstream mechanism, it is provided as a claw extending inward from both sides. Note that the auxiliary guide 34 may be provided with the locking claw 35 depending on the mode of specifications.

As described above, two sets of the pin winding portions 3 are provided symmetrically on both sides along the length of the endless belt 21. That is, the position of the pin 31 on one side and the position of the pin 31 on the opposite side across the endless belt 21 are also at the same position, and the direction of connecting the pins is the width direction of the endless belt 21 (widthwise direction or advancing direction). Can also be said to be orthogonal to). Due to this symmetrical positional relationship, the pins 31 come into contact with each other at predetermined two positions on both sides of the undeployed box HB, the posture of the bundle is maintained between the sets of the pins 31, and the bottom side swells to make the posture unstable. Stable transfer is realized by suppressing this.

As described above, the transfer device 1 can stably transfer the unexpanded box whose one side is likely to swell when bundled, by aligning the directions. Since the terminal sprocket 332 has a small diameter so that the pin 31 does not interfere with the downstream mechanism and escapes in the horizontal direction, the transfer device 1 has high versatility and the degree of freedom in designing the line can be increased. ..

Depending on the mode of specifications, the bottom of the unexpanded box may be faced up and the pins may be applied from above.

In addition, in the present invention, the transfer symmetry may be not the undeployed box HB but a flat object of the same shape in which one side bulges when bundled in the same direction. For example, it can be applied to transfer a bundle of items having a slight irregularity on the surface, such as disposable body warmers and individually wrapped masks.
