Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a type of a multi-layer conveyor belt, and more particularly, to a multi-layer conveyor belt capable of increasing the transport length of the conveyor belt in a limited space and drying a conveyed product for a sufficient time during a transport process. About.

[0002]

[Prior art]

 Pulp molded articles and products after varnish application require a heat drying process. In particular, pulp molded products cannot be manufactured without heating and drying for a sufficient time. The greater the volume of the article, the longer the required drying time. In order to obtain sufficient drying time for articles, it is necessary to have a drying room with a sufficient area, and also to install a flat conveyor belt of sufficient length in the drying room and transfer the workpiece to the conveyor belt. It is necessary to heat and dry for a sufficient time above to ensure that the drying requirements are achieved when the workpiece is delivered.

[0003] The transport length of the above-mentioned flat conveyor belt is determined by the design of the conveyor belt, and is also limited by the area of the drying room. The flat conveyor belt has the following drawbacks in use. 1. The installation area of the conveyor belt in the drying room was relatively large. In order to achieve the purpose of drying, the trader must make the transport length of the conveyor belt long enough to complete the drying operation on the workpiece, so that a relatively large drying chamber is provided. It was necessary to install this conveyor belt mechanism, which increased the factory area and increased the manufacturing cost. 2. The energy consumed during drying was relatively large. When the area and volume of the drying room became large, many energy resources were consumed until the temperature of the entire drying room was reduced to the minimum temperature required for drying, and energy resources were wasted.

[0004]

[Problems to be solved by the invention]

 In view of the above-mentioned drawbacks of the conventional planar conveyor belt, the present invention has as its main object to provide a kind of multi-layer conveyor belt, which can be installed within a limited area and has a reduced length of the conveyor belt. A multi-layer conveyor belt that can be provided as long as necessary for the drying operation, reduces the occupation area of the drying room, and reduces waste of energy resources.

In the multilayer conveyor belt of the present invention, a stopper wall is provided in each of a curved portion of the conveyor belt and a trajectory portion to be vertically transported, and the outside of the mounting unit (left side or right side) is provided. ) Is stopped, thereby canceling the transport inertia of the curved portion of the mounting unit, thereby making the mounting unit impossible to rotate and preventing inclination during vertical transportation.

A pulley holder is provided on each of the left and right end surfaces of the mounting unit near the front and rear edges, and an outer edge of the pulley holder is a vertical rod. Pulleys are provided at upper and lower ends of the vertical rod, respectively. The frictional force is reduced due to the collision of the pulley with the stopper wall.

【Example】

 As shown in FIGS. 1 and 2, the multi-layer conveyor belt according to the present invention includes a small number of mounting units 10 and two symmetrically arranged chains 20 in front and rear. Each mounting unit 10 is installed between two front and rear chains 20. Both ends of the central pivot 11 of each mounting unit 10 are fixed to two chains 20 respectively. The chain 20 is bent by the installation of the proket 21, and the chain 20 transports each mounting unit 10 above the bottom layer to the highest layer, and further moves to the lower layer successively from the highest layer. Transport to the bottom layer, thus completing one circulating transport.

The above-described chain 20 is bent at a sprocket 21 portion. By design, the chain 20 bends 90 ° through one sprocket 21 and completes a 180 ° bend through the second sprocket 21. That is, the mounting unit 10 is transported to a lower layer. Therefore, by appropriately installing the sprocket 21, the chain 20 and the mounting unit 10 form a multi-layered transportation trajectory. The two sprockets 21 achieve the purpose of the bent transport between the pair of upper and lower layers, and if necessary, accommodate the workpiece 30 left on the mounting unit 10 by appropriately determining the height difference between the upper and lower layers. It can be done.

As shown in FIG. 4, the pivot 11 of the mounting unit 10 described above is inserted into a hole of the mounting unit 10 via the shaft sleeve 15 and has a rotation function. When the chain 20 is bent after passing through the sprocket 21, the pivot 11 is driven and moved, and the pivot 11 is driven and rotated, so that the mounting unit 10 can be kept in a horizontal state. The upper workpiece 30 does not fall off.

As shown in FIGS. 1 and 5, each of the curved portions of the above-described conveyor belt is provided with one stopper wall 40, which abuts on the outside of the mounting unit 10 (left side or right side). In addition, the transport inertia of the bent portion of the mounting unit 10 is canceled to prevent the mounting unit 10 from rotating. In addition, in the vertical transport portion of the chain 20, the side of the mounting unit 10 abuts against the stopper wall 40, so that the mounting unit 10 is prevented from tilting.

One pulley holder 12 is provided near the front and rear edges of the left and right end surfaces of the mounting unit 10, and the outer edge of the pulley holder 12 is a single vertical rod 121. One pulley 122 is provided, and the frictional force between the upper and lower pulleys 122 and the stopper wall 40 is reduced by the contact of the upper and lower pulleys 122 with the stopper wall 40. The mounting unit 10 is placed in a stable horizontal state by the contact of the upper and lower pulleys 122.

Two rollers 13 are provided on the front and rear end faces of the mounting unit 10, respectively. The two rollers 13 having the same end face move along the track 50, and when reaching the curved portion, one upper track 51 is further formed. When the outer roller 13 is separated from the lower track 50 by the addition of the upper roller 51, the mounting unit 10 is prevented from tilting due to the limitation of the upper track 51. When the conveyor belt is in the vertical transport section, the stop wall 40 has a track function.

The above-described conveyor belt requires that the first and second layers at the bottom have a wider width than the respective layers above, so that the workpiece 30 is placed on the mounting unit 10 or It is lowered from the mounting unit 10.

[0017]

[Effect of the invention]

 The multi-layer conveyor belt provided by the present invention was dried and completed at the unloading section, with the length and time of transport of the workpiece on the conveyor belt being sufficient for the drying operation under the multi-layer transportation system. The workpiece can be removed. The design of the upper and lower multi-layers can reduce the area required for the drying room and is economical. Therefore, the present invention is a conveyor belt most suitable for use in the drying room.
