Description

  The present invention relates to an article transport belt for transporting articles that are vulnerable to impact, such as fruits and vegetables.

  Generally, a conveyor for transporting various articles includes an endlessly formed transport belt and a plurality of pulleys around which the transport belt is wound, and the pulleys are rotated to transport the articles on the transport belt. It is configured. However, in the conveyor, for example, when an article that is vulnerable to impact, such as fruits and vegetables, falls on the conveyor belt, the article is damaged by the impact and the commercial value is lowered.

Therefore, the surface of the conveyor belt has cushioning properties such as providing a rubber with a small coefficient of restitution, providing a stress dispersible gel material consisting of a large number of irregularities, or providing a cushioning material entangled with a filamentous resin. A member that absorbs an impact on an article by a member is known (for example, see Patent Documents 1 to 3).

  However, in the case where the shock-absorbing member is simply provided on the surface of the conveyor belt as described above, it is possible to effectively absorb the shock caused by vibration during transportation even though it can absorb the shock when dropped. In order to reliably convey an article that is not susceptible to impact, such as being unable to do so or having its buffering performance deteriorated due to deterioration of the member, the impact absorbing power was insufficient.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an article conveying belt that can reliably convey an article that is vulnerable to impact without damaging the article.

  In order to achieve the above-mentioned object, the present invention is an article transport belt for carrying and transporting an arbitrary article on a belt body made of sheet-like rubber, and the belt body can be elastically deformed in the thickness direction of the belt body. A plurality of hollow protrusions are provided, and a fluid made of gas or liquid is sealed inside each protrusion.

  As a result, the plurality of protrusions are elastically deformed by contact with the article, and the buffering action of the fluid in the protrusions, that is, the fluid is compressed or flows in accordance with the load of the article, so that the drop impact of the article and vibration during conveyance The shock caused by is absorbed. Further, since the article is supported by the plurality of protrusions, the pressure applied to the article from the protrusions is dispersed.

  According to the article conveying belt of the present invention, it is possible to absorb the impact when the article is dropped and conveyed by the elastic deformation of the plurality of protrusions and the buffering action of the fluid. Can be transported. At that time, since the article can be supported by the plurality of protrusions, the pressure applied to the article from the protrusions can be dispersed, and damage to the article due to local pressure can be effectively prevented.

  1 to 5 show an embodiment of the present invention. FIG. 1 is a partial sectional view of an article conveying belt, FIG. 2 is a perspective view of a buffer unit, FIG. 3 is a plan view thereof, and FIG. FIG. 5 is a partial sectional side view of the conveyor.

  This article transport belt includes a belt main body 1 made of sheet-like rubber and a plurality of rubber shock-absorbing units 2 attached to the surface of the belt main body 1, and is vulnerable to impacts such as fruits and vegetables. The article A is placed and conveyed.

  Each buffer unit 2 includes a sheet-like member 2a formed in a square shape and a plurality of hollow protrusions 2b provided on the upper surface of the sheet-like member 2a. The sheet-like member 2a is formed on the surface of the belt body 1. It is pasted. Each protrusion 2b is formed in a cylindrical shape that can be elastically deformed in the vertical direction (the thickness direction of the belt main body 1), and a plurality of protrusions 2b are arranged in the front-rear direction and the width direction. Between each protrusion 2b, a plurality of communication portions 2c are provided to communicate the inside of each protrusion 2b in the front-rear direction and the left-right direction. Each communication portion 2c is arranged on the upper surface of the sheet-like member 2a with the lower end side of each protrusion 2b. It is provided to communicate. In addition, a fluid B made of gas or liquid is sealed inside each projection 2b, and an outlet 2d for allowing the fluid B to flow into and out of each projection 2b is provided at one end of the sheet-like member 2a. Yes. An external pipe 3 made of a flexible tube can be connected to the outflow / inlet 2d, and fluid B can be injected into each projection 2b from a fluid injector 4 connected to the external pipe 3. The outlet 2d is provided with a valve 2e. By opening the valve 2e, the fluid B in each projection 2b can be discharged from the outlet 2d.

  As shown in FIG. 5, the article conveying belt is configured such that the belt body 1 is wound around the pulley 11 of the conveyor 10, and the article A placed on the upper surface of the belt body 1 is conveyed by the rotation of the pulley 11. Yes. At that time, the plurality of protrusions 2b of the buffer unit 2 are elastically deformed by contact with the article A, and the buffering action of the fluid B in the protrusion 2b, that is, the fluid B is compressed or flows according to the load of the article A. The impact due to the drop impact of the article A and the vibration during transportation is absorbed. Further, since the article A on the belt body 1 is supported by the plurality of protrusions 2b, the pressure applied to the article A from the protrusions 2b is dispersed.

  Thus, according to the article conveying belt of this embodiment, the belt body 1 is provided with a plurality of hollow protrusions 2b that can be elastically deformed in the thickness direction of the belt body, and a gas or liquid is provided inside each protrusion 2b. Since the fluid B is sealed, the impact when the article A is dropped and conveyed can be absorbed by the elastic deformation of the protrusion 2b and the buffering action of the fluid B, and the article vulnerable to the impact can be reliably conveyed without being damaged. be able to. At this time, since the article A can be supported by the plurality of protrusions 2b, the pressure applied to the article A from the protrusions 2b can be dispersed, and damage to the article A due to local pressure can be effectively prevented. it can.

  Since the buffer unit 2 having a plurality of protrusions 2b provided on the sheet-like member 2a is attached to the surface of the belt body 1, the number of buffer units 2 corresponding to the length and width of the belt body 1 is used. And versatility can be improved.

  Further, since the protrusions 2b are formed in a columnar shape, the protrusions 2b can be arranged with high density, and the pressure applied to the article A can be dispersed by more protrusions 2b.

  Further, since the inside of each protrusion 2b is communicated with each other by the communication portion 2c, the fluid B can be moved between the plurality of protrusions 2b in contact with the article A, and the pressure applied to the article A from the plurality of protrusions 2b. Can be made uniform.

  Furthermore, since the outflow inlet 2d for inflow and outflow of the fluid B in each projection 2b is provided, for example, when liquid is used for the fluid B, it is not necessary to enclose the fluid B until use, and the weight can be reduced. Can be planned.

  In addition, since the outlet 2d is opened and closed by the valve 2e, the pressure of the fluid B in each projection 2b can be adjusted by the inflow of the fluid B and the discharge of the fluid B by opening the valve 2e. Thereby, since the impact absorption power of each protrusion 2b can be arbitrarily set according to the size and weight of the article A, it is extremely advantageous when conveying a wide variety of articles.
