Description

The present invention relates to a conveyor type transport device for transporting cargo from a high place to a low place without power.

In conventional general cargo handling work, when cargo such as cardboard is carried out from the upper floor of a building, the worker holds the cargo with both hands and uses the stairs to handle the cargo. Since the weight of corrugated cardboard is 20 kg or more, if a large number of corrugated cardboards are manually handled, the cargo handling work becomes extremely heavy labor and the time required for cargo handling becomes long.
Conventionally, belt conveyors and roller conveyors have been widely used as transport means for cargo handling, but they are heavy and large-scale transport devices including drive mechanisms, and are places where cargo handling is performed every time cargo handling work is performed (buildings, etc.). It is difficult to carry it to and use it. Even if it can be carried in and installed, it cannot be used in places where power (power supply) cannot be obtained.
On the other hand, it is known that a non-powered roller conveyor is tilted and slid down on the conveyor while rotating the roller by utilizing the weight of the load (for example, the load can be transported). Patent Document 1).

This conveyor-type transport device operates without power, and is on the side of the start end of the conveyor (the end that becomes the tilted upper side when the transport device is tilted in the longitudinal direction as shown in FIG. 4) and the conveyor. The non-drive type rotating bodies 1a and 1b (rotary wheels) on the end (also the end portion on the lower inclined side) side, and the endless carrier 2 rotatably wound between these rotating bodies 1a and 1b. It is provided with a braking mechanism 3 that brakes the rotation of the endless carrier 2 and whose braking force can be adjusted, and is placed on the endless carrier 2 when the transport device is arranged in an inclined state in the longitudinal direction. The endless carrier 2 is pulled by the tilting component force (component force parallel to the tilted endless carrier surface) of the load of the object to be transported (hereinafter referred to as "luggage"), so that the endless carrier 2 is moved by the braking mechanism 3. It is configured to rotate while being braked.

This conveyor type conveyor can be used by arranging it in an inclined manner on a staircase or the like without using the legs, but in the present embodiment, the legs 4 (4a, 4b) for supporting the conveyor body are provided. There is. That is, the conveyor of the present embodiment includes a conveyor-type conveyor mechanism A and a leg 4 that supports the conveyor A, and the conveyor A has the conveyor start side and the conveyor end side as described above. The non-drive type rotating bodies 1a and 1b, the endless carrier 2 rotatably wound between the rotating bodies 1a and 1b, and the rotation of the endless carrier 2 are braked and the braking force thereof is applied. It is provided with an adjustable braking mechanism 3.

The conveyor type conveyor of this embodiment is a belt conveyor type conveyor, and the endless conveyor 2 is composed of a pair (two strips) of parallel endless belts 14 having a small width, and the rotating bodies 1a and 1b are each. Each has a pair of pulleys 15 around which a pair of endless belts 14 are wound. The reason why the endless transport body 2 and the rotating bodies 1a and 1b are configured in this way is to reduce the weight of the entire transport device. Here, in order to prevent slipping between the endless belt 14 and the pulley 15, it is preferable that the endless belt 14 is a toothed endless belt and the pulley 15 is a toothed pulley that meshes with the toothed endless belt.
Each of the rotating bodies 1a and 1b is rotatably (free-rotated) and freely supported (axially supported) at both ends of the support frame 6 along the longitudinal direction of the device. The support frame 6 is composed of side plates 60 on both sides in the width direction of the device, a connecting member 61 for connecting the side plates 60 at a plurality of places, and the like. Further, the support member 16 (endless carrier 2) that supports the upper rotating portion of the endless carrier 2 (two endless belts 14 in this embodiment) along the longitudinal direction of the support frame 6 (both side plates 60). The receiving member) is provided, and the upper rotating portion of the endless carrier 2 on which the load is placed moves while sliding on the support member 16.
The endless belt 14 constituting the endless carrier 2 may have three or more strips, and each of the rotating bodies 1a and 1b is provided with a plurality of pulleys 15 according to the number of the endless belts 14.

The braking mechanism 3 may have any form and structure as long as it brakes the rotation of the endless carrier 2 and its braking force can be adjusted. In particular, the rotating body 1a or the rotating body 1b It is convenient and preferable that the rotation of the endless carrier 2 is braked by braking the rotation of the brake, and also in this embodiment, a braking mechanism 3 for braking the rotation of the rotating body 1a on the starting end side of the conveyor is provided. ing. Further, by providing the braking mechanism 3 for braking the rotation of the rotating body 1a on the starting end side of the conveyor in this way, the worker who puts the load on the conveyor can adjust the braking force of the braking mechanism 3 at hand. , Workability and operability are good.

The braking mechanism 3 includes, for example, a fixed-side braking member 7x provided on the support frame 6, and a rotating-side braking member 7y that rotates integrally with the rotating body 1a or the rotating body 1b in contact with the fixed-side braking member 7x. One of the fixed-side braking member 7x and the rotating-side braking member 7y may be pressed against the other, and the braking force adjusting means 8 for adjusting the pressing pressure (contact pressure) may be provided. Here, the fixed side braking member 7x means a braking member on the side that does not rotate with respect to the rotating side braking member 7y. The braking force adjusting means 8 usually has a urging means for pressing one of the rotating side braking member 7y and the fixed side braking member 7x against the other, and also has the fixed side braking member 7x due to the urging of the urging means. The contact pressure with the rotating side braking member 7y can be adjusted and the contact pressure can be maintained.

FIG. 3 schematically shows an embodiment of such a braking mechanism 3, in which the braking force adjusting means 8 holds the rotating side braking member 7y slidably and is shafted on the rotating shaft 9 of the rotating body 1a. The holding means f (the holding means f also rotates integrally with the rotating body 1a) provided so that the direction and position can be adjusted, and the holding means f and the rotating side braking member 7y are interposed between the holding means f and the rotating side braking member 7y. Has an urging means e that presses against the fixed side braking member 7x. The braking force adjusting means 8 moves the holding means f in the axial direction of the rotating shaft 9 to adjust the position, so that the fixed side braking member 7x and the rotating side braking member 7y come into contact with each other due to the urging of the urging means e. The pressure (pressing pressure of the rotating side braking member 7y against the fixed side braking member 7x) can be adjusted and the contact pressure can be maintained. The holding means f may be capable of position adjustment (movement) in the axial direction by using, for example, a screw mechanism or the like, and may be held at the adjusted position. By adjusting the contact pressure between the fixed side braking member 7x and the rotating side braking member 7y with such a braking force adjusting means 8, the rotational braking force of the rotating body 1a can be adjusted.
Such a braking mechanism 3 has an advantage that the rotation of the rotating body 1a can be appropriately braked by a relatively simple mechanism, and the braking force can be adjusted by a simple operation by the user.

Further, as another embodiment of the braking mechanism 3, the braking force adjusting means 8 is provided on the support frame 6 side, and the fixed side braking member 7x is changed to the rotating side braking member 7y by the urging means e of the braking force adjusting means 8. It may be pressed against. In this case, the braking force adjusting means 8 slidably holds the fixed-side braking member 7x, and the holding means f provided on the support frame 6 so that the position of the rotating shaft 9 can be adjusted in the axial direction, and the holding means f. It has an urging means e that is interposed between the fixed side braking member 7x and the fixed side braking member 7x and presses the fixed side braking member 7x against the rotating side braking member 7y. Also in this case, the holding means f provided on the support frame 6 side is moved in the axial direction of the rotating shaft 9 to adjust the position, so that the fixed side braking member 7x and the rotating side braking member by the urging of the urging means e are adjusted. The contact pressure with the 7y (the pressing pressure of the fixed side braking member 7x against the rotating side braking member 7y) can be adjusted and the contact pressure can be maintained. In order to enable the holding means f to be position-adjustable (movable) in the axial direction and to be held at the adjusted position, for example, a screw mechanism as described above may be used.

The braking mechanism 3 may be any as long as the braking force can be obtained by friction between the fixed side braking member 7x and the rotating side braking member 7y. Therefore, the braking mechanism 3 of the above-described embodiment rotates with the fixed side braking member 7x. In this method, a braking force is obtained by pressing one of the side braking members 7y against the other. For example, the rotating side braking member 7y such as a metal disc is sandwiched between fixed side braking members 7x such as a brake shoe to obtain the braking force. It may be a method of obtaining.
Further, the braking mechanism 3 of the above-described embodiment is such that the rotation of the endless carrier 2 (endless belt 14) is braked by braking the rotation of the rotating body 1a (pulley 15). As shown in the embodiment described later, the braking mechanism 3 may directly brake the rotation of the endless carrier 2.
The materials of the fixed side braking member 7x and the rotating side braking member 7y are arbitrary, and both members may be made of friction materials of the same material or different materials, and one (for example, the rotating side braking member 7y) is made of a metal disc. The other (for example, the fixed side braking member 7x) may be made of a friction material.

The leg portions 4 (4a, 4b) are provided on the conveyor start end side and the conveyor end side, respectively, and the transport mechanism portion A is supported by both leg portions 4a, 4b.
In order to support the transport mechanism A at an appropriate tilt angle regardless of the tilt of the stairs or the like arranged at the time of use, the legs 4a and 4b are configured to be expandable and contractible so that the length can be adjusted. be. Similarly, the upper ends of the legs 4a and 4b are rotatably pivotally supported by the support frame 6 constituting the transport mechanism A, and are fixed at arbitrary rotation positions by fixing means (not shown). I am trying to do it. Further, in order to facilitate the transport of the transport device, it is preferable to rotate the legs 4a and 4b at the pivot portion 17 so that the legs can be folded into a state substantially parallel to the transport mechanism portion A.
Further, in order to support the transport mechanism portion A at a gentle inclination angle, the leg portion 4b on the conveyor end side can be made longer than the leg portion 4a on the conveyor start end side, that is, the maximum length of the stretchable leg portion 4. It is configured so that the leg portion 4b> the leg portion 4a.

In order to prevent the load placed on the endless carrier 2 (endless belt 14 in this embodiment) inclined in the longitudinal direction from slipping and slipping off from the end side of the conveyor when the conveyor is used, the endless carrier 2 is used. On the outer surface of No. 2, a plurality of protrusions 5 for locking the object to be transported are provided at intervals in the longitudinal direction of the endless carrier. Since the protrusion 5 is for locking the load so as not to slip off from the endless carrier 2, the shape and installation form are arbitrary, and for example, a protrusion such as a pin may be used, or a predetermined protrusion 5 may be used. It may have a width, or it may be a protrusion provided along the width direction of the endless carrier 2. The protrusion 5 may have a height that can securely lock the load and does not hinder the rotation of the endless carrier 2, and is generally preferably at a height of about 5 to 20 mm. The installation interval of the protrusions 5 in the longitudinal direction of the endless carrier may be such that the load that is about to slide down on the endless carrier 2 is always caught and locked. When the total length is about 2 to 3 m, the interval may be about 0.5 to 1.5 m.

Further, when the endless carrier 2 is an endless belt 14 as in the present embodiment, it is preferable to provide a rubber lining for preventing the cargo from slipping on the outer surface of the endless belt 14 (for example, a rubber sheet is attached).
In the present embodiment, the protrusion 5 is provided for safety so that the load can be locked even if the load slips on the endless carrier 2, but when the load is placed on the conveyor (endless carrier 2). It is also possible to ensure that the load is locked to the protrusions 5, and in this case, the installation intervals of the protrusions 5 in the longitudinal direction of the endless carrier are relatively narrow.
The length of the transport device of the present invention is not particularly limited, but in general, about 2 to 3 m is suitable from the viewpoint of transportability and the like.

FIG. 4 shows a usage state of the conveyor type transfer device of the present embodiment.
This usage example shows a case where the transport device is arranged on the stairs to transport the luggage g (cardboard), and the lengths of the legs 4a and 4b are adjusted so that the transport mechanism portion A has a predetermined inclination angle.
