Description

Carrier Coupling Units for Lightweight Power and Free trolley Conveyors

The present invention consists of a box-shaped power rail and a horizontal rail-shaped free rail at the bottom, and a propulsion to pull the carrier to the bottom of the connection link crushed on the chain, so as to smoothly towing and disengage the carrier In addition, the chain can be prevented from being bent on the rising slope and the falling slope on the path of the carrier, and the propelling hole of the chain and the follower hole of the carrier are securely engaged to prevent the breakage during towing. Since it is attached to two supporters and connecting links, which are crushed in the lower part of the chain, the propulsion and follower can be smoothly towed even if the chain sags while the carrier is towed. The present invention relates to a carrier coupling device of a lightweight power and free trolley conveyor, comprising a box-shaped power rail through which a lightweight chain passes, and a free rail with a cross-section cross-section through which the carrier passes, and the chain has a propulsion tool ( PUSHER DOG) is pulled to pull the hook of the carrier below, to transport the workpiece or to facilitate storage and sorting, and to reliably engage the prop of the chain and the following of the carrier to ensure that the chain is being transported. The present invention relates to a carrier coupling device of a lightweight power and free trolley conveyor that prevents the propulsion and following from falling off when passing through the slope.

In general, a power and free trolley conveyor is a conveyor that engages the propulsion port of the chain and the follower of the carrier, and conveys the workpiece on the carrier and the hanger while continuously driving the chain by the driving body. When you stop the work or stop the workpiece on the hanger or put the prisoner on the hanger, and sort or store the workpiece, the chain is driven by the drive continuously and the carrier and the workpiece stop at the desired position. It is a conveyor with the ability to do it.

When the chain and the propulsion drive are continuously driven, the lower carrier and the follower should be stopped, the hauling material being transported or the sorting and storing should be smoothly engaged and disengaged from the follower of the carrier. The propelling openings of the chain shall not be peeled off the following openings of the carrier except at the stop or sorting and storing at the desired position.

However, since the propulsion tool of the small and light chain is usually extracted from the chain to one support point, when the propulsion tool of the chain is towing the carrier, the propulsion tool is inclined and the engagement between the propulsion tool and the follower is unstable and the propulsion tool is peeled off. There was a problem, especially when the chain fell and the towing on the incline was more prone to tilting due to the chain's bending, causing it to fall off or carry the workpiece.

The present invention is to solve the above problems and to make a compact and lightweight power and free trolley conveyor, the propulsion hole of the chain in the lower portion of the lower portion of the chain using a link that is connected to each other and the support that is extracted from the chain In order to prevent the inclination, which is the propulsion tool, the propulsion tool is inclined to be peeled off even if the chain is bent on the inclined part. The shape of the propulsion tool is designed so that the propulsion port of the chain does not come off, and the small and light power and free trolley conveyor can transport the workpiece stably, and it is easy to transport and manage the workpiece. .

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a side view of a lightweight power and free trolley conveyor according to the present invention. In general, in the lightweight power and free trolley conveyor, the power rail 1 through which the chain passes and the free rail 2 through which the carrier passes and the chain (3) and the propulsion tool 15, the front carrier 16, the rear carrier 17, the load bar 22, and the hanger 23 are comprised.

In FIG. 5, the propelling tool 28 extracted from the lowering link 26 extending downward from the side link of the chain is driven by the lowering pin 27, and the trailing hole 29 is pulled by the towing ring 28a. Will be done. When storing the carrier during towing (STORAGE), the towing ring, which is the propelling hole, is lifted up by the bumper 30a, which is the preceding rear carrier 30, and is peeled off and stored in the following sphere. At this time, the tow ring 28a, which is the propulsion tool that is lifted, extends rearward from the traction pin 27 and descends due to gravity because the tow ring portion is heavy. The tow ring is returned to the stopper 28C without falling down from the predetermined position while contacting the chain extraction link 26, the chain and the propulsion proceeds by a separate drive device. As shown in Fig. 5, the propulsion tool and the follower are shaped like hooks 28a and 29a to ensure traction, but if the chain sags or is loosened, the traction ring 28a is heavy and the traction ring is pulled out. Even when the propulsion tool is inclined downward together in the link 26 and the propulsion tool makes contact with the bumper 30a, the towing ring is not lifted up to a predetermined height so that it is not detached from the follower.

6 is a view showing the relation between the propulsion tool and the follower on the descending slope, and since the carrier is in a free state rather than the constant speed of the chain, the speed is much faster, so that the front engaging member 29b of the follower is the front engaging member 28b of the propulsion tool. At this time, the propulsion pin is driven by the component of the force acting on the propulsion port and the contact angle of the front engaging member 28b, which is the propulsion tool, behind the contacting member. ) Will lift up as a hinge. The propulsion shaft is lifted up, the chain side link 25 and the traction link 26 are inclined, and the chain pins 32 and 33 are tilted up and down by a predetermined height so that the chain 31) (34) is broken. In addition, the propulsion was lifted and the back 28d was pushed in contact with the lower portion of the power rail 35 so that the back portion of the propulsion and the lower surface of the power rail were abraded, and the engagement amount (A) of the engagement portion was raised as the propulsion was lifted up. There is a fear that the propulsion tool may escape while following the tow.

The carrier coupling device of the power and free trolley conveyor as described above, when the operation of the present invention in detail compared to the conventional method will be described as follows.

In FIG. 2 and FIG. 3, a chain 3 driven by a predetermined driving device is formed inside the power rail 1 having a box-shaped cross section, in which the chain of side rollers 4 in the vertical direction is transverse. Side rollers (5) are provided to prevent them from being biased in the direction, and support links (6a) (7a) pushed downward from the side links (6) (7) are connected to each other by a coupling pin (11) (14). 8) (10) is crushed, and the link (9) connecting the two links between the connecting link is pinned by the pin (12) (13). Then, the support 6a has a propulsion tool 15 simultaneously pushed by the tracking pin 14 to pull the front carrier 16. In the lower part of the power rail, there is a free rail (2) having a horizontal cross section, and there is a front carrier (16) which is towed by a propulsion hole inside the free rail, and a rear carrier (17) which is basically paired with the front carrier is configured. . The front carrier has a follower 18 engaged with the propulsion tool, and the rear carrier has a bumper 19 necessary for traction release of the propulsion tool.

In FIG. 2, the towing ring 15b of the propulsion tool which is driven simultaneously with the linking link 10 by the chucking pin 14 extends long behind the chucking pin for omnidirectional traction, and a predetermined engagement with the follower is ensured. It is inclined at an angle, and it is basically based on the drilling pin 14, so it always tries to be inclined downward, but the stopper 15d attached to the follower comes in contact with the upper portion of the connection link 10 to a predetermined height. Will be maintained. In order to prevent runaway of the following ball during towing of the follower in front of the towing ring 15b and to engage the towing on the descending slope, the engaging member 15c has a predetermined inclination. To be surely towed

The linking links 8, 9 and 10 which are crushed at the lower part of the chain chucking links 6a and 7a have chucking pins 12 and 13 so that the link is bent when the chain proceeds horizontally. It is composed of two supports 6a and 7a so that even if the chain sags or the stopper 15d of the propulsion tool is in contact with the upper part of the link 10, the propulsion tool is always in parallel with the power rail. It is supposed to have.

When the propelling tool meets the protruding member 19a at the rear of the bumper 19 of the preceding rear carrier during the towing of the follower with the towing ring 15b, the lower protruding member 15a serving as the propelling tool has a predetermined tilt, so that The towing ring 15b is lifted up with the pin 14 as a hinge and the towing ring is lifted off from the towing ring 18a of the follower. The towing ring passes through the bumper 19 in a lifted state, and after completion of the passage. Since the tow hook side is basically heavy, it comes down again and the stopper 15d comes into contact with the upper portion of the connection link 10 so as not to come down anymore to maintain a predetermined height.

In Fig. 4, in the descending inclined portion, when the propulsion tool pulls the follower, it is pulled in engagement with the front engaging member 18b of the follower by the engaging member 15c in front of the towing ring 15b. In addition, the front engaging member 15C of the propulsion tool has a predetermined inclination, and is firmly engaged with the front engaging member 18b of the following sphere, thereby preventing the following sphere from being released during towing, and having two supports supported by the chain ( 6a) (7a) has a box structure with connecting links (8) (9) (10) and chain (3), which prevents the chain from breaking and smoothly pulls even on the inclined portion, and the runaway of carrier and workpiece To prevent.
