Have been. The gripping mechanism is always provided with a force in a direction in which the angular displacement gripping member is separated from the fixed gripping member, and the closing cam provided along the movement path of the chain causes the angular displacement gripping member to oppose the force. Is angularly displaced so as to close the gap with the fixed gripping member, and the posture is maintained by the action of the stopper. Further, when the stopper is removed by an opening cam provided along the movement path of the chain, the angular displacement gripping member is angularly displaced so as to open the gap with the fixed gripping member by the force. It is. Then, the chain with the gripping mechanism is caused to travel along the guide rail.

[0008] In the above-mentioned five known techniques,
The first roller and the second roller are used when the chain with the gripping mechanism changes its running direction (to change its direction to a direction deviating from an imaginary plane formed by its own rotation center line and the connecting direction of the chain link). 2), respectively, in rolling contact with the guide surface of the guide rail, thereby restricting the running direction of the chain with the gripping mechanism.

On the other hand, the chain with the gripping mechanism is configured to pass through a position corresponding to the printed matter discharge portion of the folding device,
A printed matter transport device in which a printed matter is gripped by a gripping mechanism passing this position is disclosed in JP-A-8-188313, Japanese Patent No. 2534175, and Japanese Patent No. 272728.
No. 1 is known.

Japanese Unexamined Patent Publication No. Hei 8-188313 discloses a structure in which the chain with a gripping mechanism disclosed in Japanese Unexamined Patent Publication No. Hei 5-97302 passes through a position corresponding to a printed matter discharge section of a folding device. It was done.

Japanese Patent No. 2534175, Japanese Patent No. 27
No. 27281 discloses a chain with a gripping mechanism stretched between chain sprockets so as to pass through a position corresponding to a printed matter discharge section of a folding device. Is designed so that the running direction can be changed on a plane perpendicular to the rotation center line of the chain sprocket, but the running direction cannot be changed so as to deviate from the plane.

[0013]

The prior art described above has the following problems.

Japanese Patent Application Laid-Open No. 5-97302 discloses a first roller and a second roller provided at the position of a link connecting portion of a chain with a gripping mechanism, that is, at the end of the link. For this reason, as shown in FIG. 11, there is no problem when traveling on a straight line portion (FIG. 11B). When the chain with the gripping mechanism runs while bending in a direction in which the traveling direction is restricted by the second roller. (Fig. 11
(a)), the first rollers make an angle α with respect to the running direction of the chain with the gripping mechanism, that is, the tangential direction of the bent portion of the guide rail, and run in a state where the contact portion with the guide rail slides on the guide rail. Will be. For this reason, the guide rail at the bent portion is greatly worn. Further, the first rollers themselves are relatively worn, and an inappropriate force acts on the bearings of the first rollers in the axial direction, so that the durability is low. Further, since the first roller runs while sliding on the guide rail, noise is generated, which is one of the causes of deteriorating the working environment. In addition, the links of the chain with the gripping mechanism are connected, so that the first rollers and the second rollers are attached to both ends of the link that is the connecting portion. For this reason, the first roller and the second roller cooperate with the guide rail, the connecting portion is restricted from moving up, down, left and right with respect to the longitudinal direction, and each link is in a state where the movement of each link is sealed. ing. For this reason, the gripping mechanism provided at each link can be applied to the printed matter being gripped even if the gripping mechanism receives an external force for some reason.
Depending on the direction of the acting force, the gripping mechanism may be broken open, and the gripped printed matter may shift or fall, and when the gripping force is large, However, a strong force acts on the printed matter being gripped, and the printed matter may be distorted, wrinkled or broken.

[0015] Japanese Patent Publication No. 59-48204 discloses that a first roller and a second roller are provided at a position of a link of a link of a chain with a gripping mechanism, that is, at an end of the link.
Is provided. Therefore, Japanese Patent Publication No. 59-48204
Japanese Patent Application Laid-Open No. 5-97302 has the same problem as that described in Japanese Patent Application Laid-Open No. 5-97302. Further, not only that, the one disclosed in Japanese Patent Publication No. 59-48204 discloses that a rod that catches printed matter and grips the printed matter with the help of a clamp is attached to one side of a link of a chain with a gripping mechanism. Since the projection is provided, when the chain with the gripping mechanism runs while gripping the printed material, the link is inclined toward the side where the gripping mechanism is provided. For this reason, each of the first roller and the second roller travels in contact with a predetermined portion of the guide rail, and the guide rail at the corresponding portion is extremely worn, resulting in low durability.

In the structure disclosed in Japanese Patent No. 2527724, a first roller is provided at a position of a link of a link of a chain with a gripping mechanism, that is, at an end of the link.
Therefore, in the relationship between the first roller and the guide rail,
There has been a problem similar to that disclosed in Japanese Patent Application Laid-Open No. 5-97302. In the device disclosed in Japanese Patent No. 2527724, a first roller is provided at an end of a link, while a second roller is provided at a substantially central portion of the link. For this reason, when the chain with the gripping mechanism travels while bending in the direction in which the traveling direction is restricted by the second roller, each rigid link is located closer to the end of the link than to the center of the link, as shown in FIG. A certain connecting portion is swung radially outward of the bent portion of the guide rail. That is, the guide rail side edge and the first
Relationship between distances a1 and a2 from roller end faces (FIG. 12 (b)) and distances b2 and c2 (FIG. 12 (a)) between guide rail side edges in curved portions of the guide rails and end faces of first rollers. Becomes b2 <a1 = a2 <c2. For this reason, when the chain with the gripping mechanism travels while bending in the direction in which the traveling direction is restricted by the second roller, the first roller slides sideways in the radial direction of the bent portion of the guide rail at the contact portion with the guide rail. As a result, the guide rail at that portion is worn and the first roller is worn.
No. 97302 and Japanese Patent Publication No. 59-48204, in addition to those described in Japanese Patent Publication No.
Further, the durability was poor. Further, a second roller provided at a substantially central portion of the link of the chain with the gripping mechanism is provided on each side of the link, one each, and is close to the first roller of the adjacent link. When the chain bends in a direction in which the running direction is restricted by the second roller, the second roller and the first roller of the adjacent link are likely to come into contact with each other, so that the aforementioned Japanese Patent Application Laid-Open No. 5-97302 and Japanese Patent Publication No. 59-48204 are disclosed. No smaller turn than what is shown in the official gazette. For this reason, it is necessary to set the radius of the bent portion of the guide rail large, and it is difficult to save space.

In the device disclosed in Japanese Patent No. 2675520, a first roller is provided substantially at the center of a link of a chain with a gripping mechanism. For this reason, there is no problem in the relationship between the first rollers and the guide rails in the one disclosed in Japanese Patent Application Laid-Open No. 5-97302. However, Patent 26
In the structure disclosed in Japanese Patent No. 75520, a first roller is provided at a substantially central portion of a link, while a second roller is provided at a position of a link connecting portion, that is, at an end of the link. For this reason, when the chain with the gripping mechanism travels while bending in a direction in which the traveling direction is restricted by the second roller, each link that is a rigid body has an end portion at the center of the link as shown in FIG. It passes through the radial center of the bent portion of the guide rail rather than the connecting portion. That is, the distances a1 and a2 (FIG. 13B) between the side edge of the guide rail and the end surface of the first roller in the straight traveling portion, and the distance b3 between the side edge of the guide rail and the end surface of the first roller in the bent portion of the guide rail. , C3 (FIG. 13A) is c
3 <a1 = a2 <b3. Therefore, when the chain with the gripping mechanism travels while bending in the direction in which the traveling direction is restricted by the second roller, the first roller slides sideways in the radial direction of the bent portion of the guide rail at the contact portion with the guide rail. As a result, the guide rail at the relevant site was relatively worn. Further, the first rollers themselves are relatively worn, and an inappropriate force acts on the bearings of the first rollers, so that the durability is low. Furthermore, since the first roller travels while sliding on the contact portion with the guide rail, noise occurs, which is one of the causes of deteriorating the working environment. Patent 267552
No. 0 discloses a first roller which passes through an operation portion provided below the other portion on a first roller guide surface of a guide rail during traveling of a chain with a gripping mechanism, the shape of the operation portion. It is disclosed that the gripper mechanism is displaced downward to open the gripper mechanism, but each link of the chain with the gripper mechanism is supported by the guide surface of the guide rail via the first roller. If the first roller is displaced following the portion, the link itself should also be displaced in accordance with the displacement of the first roller, and it is not clear whether the gripping mechanism opens regardless of the description in the publication.

In the apparatus disclosed in US Pat. No. 4,638,906, a first roller is provided at a substantially central portion of a link of a chain with a gripping mechanism. For this reason, there is no problem in the relationship between the first rollers and the guide rails in the one disclosed in Japanese Patent Application Laid-Open No. 5-97302. Also, USP
No. 4,638,906 discloses that the second roller is
Like the first roller, the link is provided substantially at the center of the link of the chain with the gripping mechanism. For this reason, USP 463890
Japanese Patent Application Laid-Open No. 6-275620 does not have the problem of those disclosed in Japanese Patent No. 2527724 and Japanese Patent No. 2675520. That is, the chain with the gripping mechanism is
When the vehicle travels while turning in a direction in which the traveling direction is limited by the rollers, the first roller does not travel while sliding sideways in the radial direction of the guide rail at the contact portion with the guide rail. Therefore, there are no various problems caused by the first roller sliding on the guide surface of the guide rail. But U
In the device disclosed in SP 4638906, a second roller is attached to one side of a link of a chain with a gripping mechanism, and a second roller and a gripping mechanism are provided on the same side of a base to facilitate attachment and detachment of the chain link. ing. For this reason, a structure is adopted in which the gripping mechanisms are attached in a hierarchical manner while avoiding interference with the second rollers. Therefore, the two protrusions provided on the link serve as a support for supporting the gripping mechanism, but the protrusions need to be provided with a thickness smaller than the outer diameter of the second roller. The durability against the impact of the operation of the mechanism and the repetitive load of gripping and releasing the printed matter is relatively low. Also,
U.S. Pat. No. 4,638,906 discloses that a link of a chain with a gripping mechanism has a shape in which a socket is provided at one end in the longitudinal direction, a plug is provided at the other end, and two protrusions for attaching the gripping mechanism are provided at the center. In addition to being relatively complicated, the surfaces of the socket and the plug need to be precisely finished so as not to interfere with the insertion connection between the two, and the two protrusions are also required to be attached with the gripping mechanism in a stable state. It must be finished so that it can be manufactured, and its manufacturing cost is high.

According to the present invention, in a printed material conveying apparatus in which a printed material is caused to travel along a guide rail by causing a gripping mechanism of a chain with a gripping mechanism to travel along a guide rail, a first roller for restricting a traveling direction of the chain with a gripping mechanism in cooperation with the guide rail. And the second roller are prevented from slipping at the contact portion with the guide rail, and the durability of the guide rail and the chain with the gripping mechanism is improved. Further, the present invention provides a printed matter transport device in which a printed matter is gripped by a gripping mechanism of a chain with a gripping mechanism and travels according to a guide rail, so that a link is relatively freely displaced,
It is an object of the present invention to prevent a printed product from being displaced or falling even if some external force acts on the printed product conveyed while being gripped by a gripping mechanism, and to prevent the printed product from being damaged. Further, the present invention provides a printed matter transport device in which a printed matter is made to travel along a guide rail by causing a gripped mechanism of a chain with a gripping mechanism to travel along a guide rail, and the durability of the link between the link of the chain with the gripped mechanism and the gripping mechanism is enhanced. It is intended to increase manufacturing cost and reduce the manufacturing cost by simplifying the shape. In addition, the present invention
In a printed matter transport device in which a printed matter is made to travel along a guide rail by gripping a printed matter with a gripping mechanism of a chain with a gripping mechanism, when the printed matter is gripped or released using a chain with a gripping mechanism suitable for each of the above-mentioned purposes, at least when the printed matter is gripped. It is another object of the present invention to stabilize the posture of a gripping mechanism so that a printed matter can be reliably gripped. Also,
