Description

[Detailed Description of the Invention] This invention relates to a banger device for a trolley conveyor, and particularly to a banger device that can appropriately change the length of the banger arm in the front and back direction depending on the type of cargo.

When a trolley conveyor conveys, for example, a body of a moving vehicle, it is necessary to open and close a door in order to assemble interior parts into the body during conveyance.

However, depending on the type of car, there are two-door types and four-door types, and the position of the door on the banger also changes depending on the size of the car itself.

Therefore, in any type of automobile, consideration must be given to ensure that the banger arm does not interfere with the opening and closing of the door.

A banger device that took this point into consideration was developed in 1654,
It is disclosed in Publication No. 91.

This disclosed conventional banger device includes a pair of left and right banger arms that are suspended from the carrier so that they can be opened and closed for loading and unloading cargo, and that have an abbreviated shape when viewed from the side.
Baggage receiving members are provided inwardly protruding at the front and rear portions of the horizontal axis of the arm.

Each banger arm is supported at only one point on the carrier.

Therefore, a strong member is required to reinforce the support1, but there is still a risk that the support of the banger arm will be uncertain, and since the length of the banger arm in the front and back direction is constant, When transporting long items, the items become unstable.

The object of this invention is to provide a trolley conveyor banger device that overcomes the above-mentioned problems.

In order to achieve the above purpose, the trolley conveyor banger device of this invention has two parallel suspension shafts that are rotatably attached to the carrier and extend in the front and back direction, and a suspension shaft that is suspended from the suspension shafts. The banger arm is equipped with a banger arm that is approximately U-shaped when viewed from the side, and a stopper that is provided on the carrier and prevents the banger arm from swinging inward.
The arm includes front and hanging members each having a ring fitted onto a hanging shaft at the upper end thereof, and both ends of the arm are connected to the lower end of the hanging member, and baggage receiving members are provided at the front and rear parts in an inwardly protruding manner. At least one of the rings of the front hanging member and the rear hanging member is fixed to the hanging shaft so that it can be moved in the front and back direction, so that the work can be carried out according to the type of cargo. The length of the banger arm in the front and back direction can be changed appropriately so that the middle arm does not get in the way and the baggage can be transported stably.

Moreover, since the banger arm is supported by two points,
Support strength is guaranteed.

The telescopic horizontal member has a front tube whose front end is fixed to the lower end of the front hanging member, a rear tube whose rear end is fixed to the lower end of the rear hanging member, and a rear part of the front tube and a front part of the rear part. It consists of an intermediate tube that is fitted over the two tubes and fastened to both tubes so that at least one of the two tubes can be taken in and out, so the front tube and the rear tube can be of the same diameter, and the intermediate tube However, it is sufficient to use one having a larger diameter than these, which has the advantage of making it easy to manufacture a horizontal member that is expandable and retractable.

The stopper is made up of two parallel protruding members that protrude from the sides of the carrier, and a supporting member that is held across both protruding members, and is fixed to the lower surface of the upper layer of the hanging member. Since the attached abutment member 22 is abutted in a swingable manner, the length of the banger arm in the front and back direction can be adjusted as described above, and the inner length of the banger arm can be adjusted. It is possible to reliably prevent swinging in the opposite direction.

An embodiment of this invention will be described below with reference to the drawings.

The specific example of the trolley conveyor shown in the drawings is a power and free conveyor.

The power rail 30 is made of steel with a ■-shaped cross section, and a drive chain is suspended from it via a number of power trolleys (not shown). The brackets are provided in a downwardly projecting manner, and the upper end of the bushing is attached to each bracket so as to be movable up and down.

Free rails 1 are arranged below the power rail 30 at a required interval.

The free rail 1 is constructed by a pair of horizontal U-shaped steel members facing each other.

The carrier 2 includes a front trolley 01J3 equipped with a pair of front and rear tilting dogs guided by the free rail 1, and a rear free trolley 4 equipped with a cam for pushing up a button at the upper end.
and an intermediate free trolley 5, and a first continuous member 6 connecting the front free trolley 3 and the intermediate free trolley 5.
and the second connecting member 7 connecting the intermediate free trolley 5 and the rear free trolley 4, and the central horizontal pin 11 at the lower end of the hanging bracket 10 provided at the center of the second connecting member 7. The upper frame 9 of the banger 8 is suspended through the upper frame 9 of the banger 8.

There are front horizontal pins 12 at the front and rear of the banger upper frame 9.
13 are provided, and hooks 14 and 15 pivotally attached to the front and rear portions of the second connecting member 7 are removably hooked to the front and rear horizontal pins 12 and 13.

Two parallel hanging shafts 17 extending in the front-rear direction are rotatably attached to the banger upper frame 9.

A pair of tubular banger arms 16, which are approximately U-shaped when viewed from the side and have an inwardly arched shape when viewed from the front, are hung from both hanging shafts 17 so as to be openable and closable for loading and unloading cargo A. ing.

The banger arm 16 has a ring 18 at its upper end that is fitted over the hanging shaft 17 and fixed by a fixing screw 20.
．． 19, and a retractable horizontal structure having front and rear hanging members 16A, 16B having both ends connected to the lower ends of the rain hanging members 16A, 16B, and having baggage receiving members protruding inwardly at the front and rear parts. It consists of member 16C.

The front hanging member 16A is straight when viewed from the side, but the rear vertical member 16B is bent forward diagonally downward from its middle diameter so as to avoid the rear wheel attachment portion of the automobile body, which is the cargo to be transported.

The front end of the extendable horizontal member 16C is the front hanging member 16A.
The front tube 31 is fixed to the lower end of the
The rear tube 32 is fixed to the lower end of 6B, and the rear tube 32 is fitted over the rear portion of the front tube 31 and the front portion of the rear tube 32, and both tubes 3
It consists of an intermediate tube 33 which is secured to both tubes 31 and 32 by tightening portions 23 at both ends so that the tubes 1.32 can be taken in and out.

The stoppers are fixed to both sides of the rear end of the carrier 2, more specifically, the banger upper frame 9, protruding laterally in an inverted V shape when viewed from the front, and having a hanging shaft 17 rotatably passed therethrough. It consists of two protruding members 21 and a support member 21A made of channel material held across both protruding members 21, and a rear hanging member 16B is attached to the support member 21A.
An abutment member 22 made of an angle member fixed to the lower surface of the upper layer is slidably abutted.

The support member A and the contact member 22 are oriented in their respective directions so that their flat surfaces are in contact with each other.

An opening/closing bar 24 having a guide roller 5 at its tip and extending outward is fixed in the middle of the rain amount lowering shaft 17.

A rail 26 for lifting and lowering a guide roller 25 is arranged at a location where the load A is taken in and out of the pair of banger arms 16.

The position of the rail 26 shown in FIG. 2 is with the pair of banger arms 16 closed; when both arms 16 are open, the rail 26 is higher than the position shown.

Posts 29 are provided on each of the front and rear sides of the banger upper frame 9 to support the gradient roller 28 at its upper end.

The slope roller 28 is guided by a rail (not shown) in the slope part of the conveyor, and is used to keep the banger 8 horizontal.

If it becomes necessary to make the length of the banger arm 16 in the front-rear direction longer than that shown in the drawing, the tightening portion 2 of the intermediate tube 33 may be
