Description

The present invention relates to a belt detachable belt conveyor device used for transporting foods or the like that may decay or deteriorate when left untreated.

In a manufacturing factory or a packing factory for raw confectionery, vegetables, meat and the like, these are generally conveyed by a belt conveyor device. If these foods remain attached to the conveyor belt, they may rot and adhere to the next food to be transported, so the conveyor belt is cleaned before and after use. In cleaning this belt conveyor device, the front side and / or the rear side of the attachment frame of the conveyor belt (endless belt, hereinafter simply referred to as “belt”) is folded to loosen the tensioning state of the belt, Since the front and back of the pulleys and belts were washed, there was a problem that there were many blind spots and left unwashed.

In order to solve these problems, a food conveyor belt conveyor as described in Patent Document 1 has been proposed. This food conveyor belt conveyor has a driven pulley on the front side and a driving pulley on the rear side, and when cleaning, etc., the front side of the conveyor frame is bent, the belt is loosened, the driving pulley and the belt receiving roller The belt can be removed by removing the driven pulley. However, in the technique described in Patent Document 1, since all of the driving pulley, the belt receiving roller, and the driven pulley are removed, the work of removing the belt is complicated, and the driving pulley is generally heavy, so that it can be attached and removed. There was a problem that it was not easy to move.

Therefore, the inventor does not need to transport and remove the driving pulley (drive pulley) as shown in Patent Document 2, and the transport surface of the feeding belt has good levelness, so that disassembly and cleaning are easy. A belt detachable belt conveyor apparatus 100 as shown in FIGS. 6 to 8 was proposed. The belt detachable belt conveyor apparatus 100 includes a gantry frame 103 provided with two left and right support members 101, 102 arranged in parallel at the top, and a head pulley 106 and a tail pulley 107 provided respectively before and after the support members 101, 102. Are provided at an intermediate position between an endless belt 110 that forms a feeding side belt 109 and a lower side belt 109 that are arranged on the head pulley 106 and the tail pulley 107, and a lower side belt 109. It has a drive pulley 113 that is hung through a tension pulley 111 and a guide pulley 112, and a feed belt receiving member 114 that is disposed directly below the feed side belt. The feed belt receiving member 114 has left and right receiving plate members 114a and 114b and a center carrier roller 114c.

The two left and right support members 101 and 102 are respectively composed of two left and right long plate members 116 and 117 and a pair of pins (bolts) 118 and 119 around the long plate members 116 and 117, respectively. The front plate member 120 and the rear plate member 121 are provided so as to be rotatable and each pair. Both end shafts of the head pulley 106 are detachably mounted in a first latching groove 122 provided on the front end side of the front plate member 120 that is a pair of left and right, and provided on the rear end side of the rear plate member 121 that is a pair of left and right. Both end shafts of the tail pulley 107 are detachably attached to the second retaining groove 123. The left and right support members 101 and 102 are connected by a connecting stay 128 via a plurality of left and right auxiliary plates 125 to 127 attached to the lower portion thereof. The left and right support members 101, 102 are provided with leg members 129 a via front, rear, left, and right mounting plates 129, thereby constituting a gantry frame 103.

As shown in FIG. 8, one end side of the drive pulley 113 can be rotated via a hinge 131 to an auxiliary support plate 130 provided at a lower intermediate position of the long plate material 116 that is a part of the support member 101. The other end side of the drive pulley 113 is fixed to the auxiliary support plate 130a provided at the lower middle position of the long plate material 117 which is a part of the support member 102. It is fixed to an attachment member 134 attached via a screw handle 133. A gear 135 is provided at the other end of the drive pulley 113 and meshes with a gear 137 attached to the output shaft of the reduction motor 136 from the horizontal direction.

When the belt detachable belt conveyor device 100 is temporarily used and the belt detachable belt conveyor device 100 is cleaned, the front plate member 120 and the rear plate member 121 are fixed to the long plate members 116 and 117. The male screws 140 and 141 with knobs are loosened, the front plate member 120 and the rear plate member 121 are bent upward with the pins 118 and 119 as the center, and the endless belt 110 on the head pulley 106 and the tail pulley 107 is loosened. Then, the left and right receiving plate members 114a and 114b are respectively removed from the mount frame 103 by putting their hands into the handle holes 142, then the carrier roller 114c is removed, and the head pulley 106 and the tail pulley 107 are removed.

Next, the fixing means 133 with handle is loosened to remove the mounting member 134 from the auxiliary support plate 130a, and the drive pulley 113 is rotated downward about the hinge 131, so that the other side of the gantry frame 103 and the drive pulley 113 A gap is formed between them. In this state, the endless belt 110 can be removed by pulling downward from the gap. Note that when the endless belt 110 is attached, the procedure is reversed.

However, the belt detachable belt conveyor apparatus 100 has the following problems.
(1) When removing the endless belt 110, the front plate member 120 and the rear plate member 121 attached to the front side and the rear side of the left and right long plate members 116, 117 are first latched via the pins 118, 119. It is necessary to bend the groove 122 and the second retaining groove 123 so that they move upward. In this case, the head pulley 106 is disengaged from the first latching groove 122, and the left and right front plate members 120 are loosely connected via the pins 118 with the left and right long plate members 116 and 117, and further, an intermediate position between the left and right front plate members 120. Since it is only connected by the connecting stay 128 that connects the auxiliary plates 127 provided at the lower portions, there is a problem that the left and right front plate materials 120 are staggered and deformed in a rhombus, resulting in poor stability. .

(2) Also, the left and right rear plate members 121 for attaching the tail pulley 107 are also detached from the second latching groove 123, and the left and right rear plate members 121 are loosened to the left and right long plate members 116, 117 via pins 119. Further, since it is only connected by a connecting stay 128 that connects the auxiliary plates 125 respectively provided at the lower intermediate positions of the left and right rear plate members 121, the left and right rear plate members 121 are staggered and deformed in a diamond shape, etc. And there was a problem that stability was bad.

(3) In the belt detachable belt conveyor apparatus 100 described above, the gear 135 meshing with the gear 137 provided on the output shaft of the reduction motor 136 from the horizontal direction is shown in FIGS. In addition, since the drive pulley 113 is removed by being pushed down and rotated through the hinge 131, the meshing of the gear 137 and the gear 135 is unreasonable, and the gear 137 is attached to the output shaft of the reduction motor 136, so that it can be easily operated. There is a problem that the gear 135 does not rotate and the gear 135 is difficult to come off from the gear 137, and the gear 135 and the gear 137 are not meshed well when assembled, and the work is troublesome.
