Abstract

PURPOSE:To perform high-density horizontal multiple conveyance, by a method wherein pallets are continuously conveyed such that horizontal return frames are installed in a multiple manner and obliquely opposite to each other, and the pallet is returned horizontally as an endless chain is moved round in a zigzag. CONSTITUTION:A pair of endless chains 6 and 6' on both sides are belted in a zigzag and circumferentially around chain sprockets 3 and 3' in plural sets of multiple return frames 7 having a number of horizontal return frames 7 positioned longitudinally and obliquely opposite to each other and are installed in multistage, and right and left guide rollers 12a, 12b, 12'a, and 12'b are rotatably secured through shafts on both sides and in front and rear positions to a number of pallets 11 installed across the endless chains. The shafts of the guide rollers, positioned laterally obliquely opposite to each other, are integrally supported to the endless chains so that horizontal return can be effected by means of the chain sprockets, positioned obliquely opposite to each other within each frame 7, guide rails 13 are installed from an intermediate position between respective frames 7 to a position of the under face of the frame, guide rails 13' are installed across the upper surface of a lateral distance between the chain sprockets and roller guide gears 4 and 4' within each frame 7, and this causes each pallet placed on the endless chains to be conveyed in a multiple manner in a zigzag as it is returned horizontally.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a horizontal multi-transport device using a pallet conveyor.

Conventionally, in endless conveying devices, the belt or plate returned from the upper moving section to the lower moving section is reversed, so horizontal conveyance is performed only by the upper moving section. Endless conveying equipment requires extra volume for the upper moving part in order to dry while performing horizontal multiple conveyance, and therefore requires a long drying chamber that can carry out multi-stage conveyance, which places restrictions on the installation location. There was a simple drawback.

In order to eliminate all of the above-mentioned drawbacks, the present invention is a high-density conveying device in which a hot end chino with a pallet is rotated left and right in a meandering manner with horizontal return mechanisms all left and right in multiple stages diagonally opposed to each other.
The present invention is characterized in that it is possible to improve the efficiency of drying work, etc. while compacting and effectively utilizing the conveyance space. Shaft pieces 2a, 2b and shaft pieces 2'a, 2'b are provided protruding from both ends of the inner surface of both sides of the frame, and chain wheels 3, 31 are suspended between the shaft pieces 2b and 2'a, which face each other obliquely in the front and back. At the same time, a roller guide gear 4.4"i is freely suspended between the shaft piece 2a and the shaft piece 2'b so as to protrude inwardly from the chain wheel 3.3I, and the left and right chain wheels 3, 31 and the roller guide gear 4, Completely form the horizontal return frame 7 with the chain wheel 5,5"k fixed to the boss of 4I and the interlocking endless chain 6,6"i, and place the horizontal return frame 7a at the front position inside the fuselage 8. + 7 b are installed in multiple stages diagonally opposed front and rear, and horizontal return frames 7'a and 7'bi are also installed in multiple stages diagonally opposed front and rear in the rear position of the fuselage 8, and one of the horizontal return frames 7'a A horizontal return frame 7'c (drawn out into the rear underframe 9 of the i7 fuselage 8 and constructed, and a pair of endless The chinos 10, 10'i are tuned in a meandering manner, and each horizontal return frame 71a + 7' b + 7' c at the rear of the endless chino 10, 10''e
Tune the belt in a meandering manner and go around it, endless cheno 10, 10'
A left guide roller 12a engages with a roller guide gear 4.4' at the same pitch as the shaft pieces 2a, 2b of the horizontal return frame at front and back positions on both sides of the pallets 11 installed in large numbers within the interior.
12b and the right guide rollers 12'a and 12'b, and the shafts of the left guide roller 12b and the right guide roller 121a are supported so that the horizontal return can be performed by the diagonally inclined chain wheel 3.31 of each horizontal return frame. are integrally supported on the endless chains 10, 10', and guide rails 13 (5) are installed on which the left and right guide rollers of the pallet 11 ride, extending from the mutual intermediate position of each horizontal return frame to the lower surface position. A guide rail 1 is placed on the upper surface of the left and right distance between the chain wheel and the guide gear.
A guide plate 14' is installed at one outer end of each horizontal return frame to reversely guide the guide roller. , the prime mover 1 installed in the rear underframe 9
The endless chino 10,10" (i7) is designed to rotate in conjunction with the 5" (i7).

Next, all the effects of the present invention will be explained with reference to embodiment figures.

In the conveying device according to the present invention, each horizontal return frame 7
Endless chinos 10, 10 are mounted on guide rollers 12a, 12b, 1.2'a, 1.2'bk guide rails 13.1.3 on both sides of each pallet 11 at mutual intermediate positions.
In horizontal return frames 7a and 71b that are installed multiple times, when the endless chinos 10 and 10' are rotated in the direction of the arrow shown in FIGS. 1 and 2, the pallet 11 Guide roller 1 which is the front part in the direction of movement
2b and 12'b are horizontal return frame roller guide gears 4
and the chain wheel 31, and the guide rail 131°1
When reaching the position of the chain wheel 3 and roller guide gear 4' from the upper surface of 3', the rear guide roller 12a + in the traveling direction
12'a also reaches the position of the roller guide gear 4 and chain wheel 3' of the horizontal return frame, and the endless chinos 10, 10
' is deflected downward by the chain wheel 3.3', and the guide rollers 12a, 12'b move 4° roller guide gear 4,
41 and is deflected downward, and the pants) 11 returns horizontally in a stable state while being supported at four points at the front and back on both sides, and the horizontal return frame 7b, which is similarly constructed multiple times.
, 7'a, the endless chains 10, 10' are turned downward by the chain wheels 3.3', and the guide rollers 12a1
12'b engages with the roller guide gears 4, 4' and is deflected downward, so that the pallet 11 returns horizontally in a stable state.

Therefore, by constructing the horizontal return frame 7'f: multi-diagonally opposite to each other and making the endless chain rotate in a meandering pattern while returning the pallet horizontally to perform continuous transport, high-density horizontal multi-transport is possible. By installing the conveying device of the present invention inside the fuselage 8 such as a dryer or a refrigerator, the space inside the fuselage 8 can be made compact and utilized to the fullest, improving work efficiency and downsizing the fuselage. It brings about the remarkable effects mentioned above, such as cost reduction.
