Description

  The present invention relates to a traveling frame device for a conveyor that is easy to perform maintenance such as cleaning and can maintain a clean state, and is particularly suitable for transporting food and the like.

  Conventionally, iron materials, stainless steel materials, aluminum materials, and the like have been used for frame materials and the like used in a traveling frame device for conveyors. However, with iron and stainless steel materials, it was necessary to use a thick plate material in order to obtain appropriate processing accuracy and rigidity, so there were limits to cost reduction and weight reduction.

  On the other hand, in the case of an aluminum frame material, there is a risk that an aluminum oxide compound will be generated if moisture or water is present in the transport environment. This aluminum oxide compound is harmful and is not preferable in terms of hygiene not only in the food processing field, but also in environments working in other industrial fields.

  Accordingly, the present applicant has solved the above-mentioned problems and has first developed a traveling frame device for a conveyor that can provide a frame material with high strength, rigidity, light weight, and high processing accuracy even with a relatively thin frame material. (Patent Document 1).

  According to this traveling frame device for a conveyor, an optimum frame material is provided as a traveling frame device used for a conveyor, a guide rail, a receiving rail, or the like.

  However, according to the traveling frame device for a conveyor of Patent Document 1, since the side surface of the conveyor chain is fitted and mounted on the traveling rail that is bent and formed inside the frame material, after the conveyor chain is mounted, When this conveyor becomes dirty, it is necessary to cut the conveyor chain at the end of the conveyor and take out the conveyor chain from the conveyor. For this reason, there has been a problem that the operation of cleaning the conveyor chain becomes extremely difficult.

  For example, when food such as milk is transported, it is assumed that milk spills and soils the conveyor chain and frame material. In such a case, it is possible to wipe off the dirt on the surface of the conveyor chain, but it is extremely difficult to wipe off the dirt adhering to the back surface of the conveyor chain and the inside of the frame.

  Moreover, there are clamps and other members that connect the frame material under the belt. If the clamps become dirty with milk that has flowed down from the conveyor chain, there is no other means than disassembling and cleaning the frame material. Is the current situation.

  Therefore, the present invention was created to solve the above-mentioned problems, and maintenance such as cleaning can be facilitated and a clean state can be maintained, and it is particularly suitable for transporting foods and the like. The purpose is to provide a device.

  According to the present invention, maintenance such as cleaning can be facilitated and a clean state can be maintained, and the initial purpose of being particularly suitable for transporting foods and the like has been achieved.

  Examples of the present invention will be described below. The basic configuration of the present invention includes a frame material 10 that supports the conveyor chain 30 and a connection clamp 20 that connects the frame materials 10 to each other (see FIG. 1).

  The frame material 10 is a pair of left and right members that support the left and right ends of the conveyor chain 30 and is disposed along the conveying direction of the conveyor chain 30. The frame material 10 is provided with a connection protrusion 11 that protrudes inside the frame material 10 and is held by the connection clamp 20. The connection protrusion 11 in the illustrated example has a substantially C-shaped cross section, and the vertical width is wider as it is closer to the connection clamp 20, and the vertical width is narrower as it is farther from the connection clamp 20 (see FIG. 1).

  Further, a support piece 12 that is bent from the connection protrusion 11 and faces vertically upward is provided. The support piece 12 supports both end portions of the conveyor chain 30. Therefore, the conveyor chain 30 can be easily lifted (see FIG. 2). On the other hand, a locking projection piece 14 bent in an L shape toward the inside of the frame member 10 is bent and extended downward from the connecting projection 11. And the tab 32 which protruded right and left from the lower surface of the conveyor chain 30 with this latching protrusion 14 is latched. The tab 32 is to be locked to the locking protrusion 14 when the conveyor chain 30 is inverted and the roll is reversed.

  A drain hole 15 is opened in each bent portion of the frame material 10. In other words, a bent portion extending from the connecting protrusion 11 to the support piece 12 and a bent portion of the locking protrusion 14 are opened (see FIG. 1). The drain hole 15 allows the liquid to be discharged from these bent portions. In the illustrated example, a drainage hole 15 is also opened in a bent portion from the connecting protrusion 11 to the locking protrusion 14.

  Further, a traveling rail 40 made of a synthetic resin is provided to be fitted to the upper end portion of the support piece 12, and the conveyor chain 30 is mounted on the traveling rail 40 in a state where the left and right ends of the conveyor chain 30 are detachably mounted.

In the illustrated example, a folding piece 13 is formed on the support piece 12 of the frame member 10 so that the upper end portion is folded outward and downward to be thick, and the running rail 40 is fitted to the folding piece 13.

  On the other hand, the connection clamp 20 is a member that connects the left and right frame members 10 inside the frame member 10. The connection clamp 20 is connected in a state where the plate surfaces of a pair of connection plates 21 provided so as to hold the connection protrusions 11 are vertical, and the connection bolt 22 penetrates these plate surfaces horizontally to connect them. (See FIG. 3). As a result, the fluid flowing down from the conveyor chain 30 flows down between the connecting plates 21.

  The connection clamp 20 further includes a connection plate 21, a connection bolt 22, a fixed tube 23, a fixed nut 24, and a fixed spring plate 25 (see FIG. 4).

  The connecting plate 21 is a plate-like member provided with gripping portions 21 </ b> A that are fitted on the connecting projections 11 and grip the connecting projections at both left and right ends. The illustrated gripping portion 21 </ b> A has a substantially C shape that is externally fitted to the connecting protrusion 11 (see FIG. 1).

  The fixed tube 23 is arranged between the two connecting plates 21, makes the interval between the connecting plates 21 constant, and covers the connecting bolt 22 that penetrates the center of the plate surface of the connecting plate 21. (See FIG. 4). The fixed pipe 23 maintains the distance between the connecting plates 21 and prevents the threads of the connecting bolts 22 from being exposed.

  The fixing nut 24 and the fixing spring plate 25 are members that are attached to the end of the connecting bolt 22. The connecting bolt 22 penetrates the fixed tube 23 from one of the two connecting plates 21 and protrudes from the side surface of the other connecting plate 21 and is attached to the protruding end of the connecting bolt 22 ( (See FIG. 3). The fixed spring plate 25 has an elastic plate shape bent on a plane W shape, and is mounted between the fixed nut 24 and the connecting plate 21. When the fixed spring plate 25 is crimped by the fixing nut 24 attached to the connecting plate 21 and the connecting bolt 22, both end portions of the fixed spring plate 25 are spread and press the left and right frame members 10.

  The conveyor chain 30 is a member supported by the frame material 10 and can be arbitrarily changed in material, size, and the like depending on the purpose of use. The conveyor chain 30 in the illustrated example is made of a synthetic resin material so as to be light and difficult to get dirty. At this time, it has a top plate 31 that protrudes from the upper surface of the conveyor chain 30 to the left and right and a tab 32 that protrudes from the lower surface of the conveyor chain 30 to the left and right (see FIG. 2). The top plate 31 is placed on the traveling rail 40, and the tab 32 is locked to the locking protrusion 14 bent in an L shape toward the inside of the frame material 10.

  During the maintenance of the present invention, the inside of the frame material 10 and the back surface of the conveyor chain 30 can be cleaned only by lifting the conveyor chain 30 from the traveling rail 40 (see FIG. 5). Even when the connection clamp 20 inside the frame member 10 is dirty, it can be easily cleaned in this state, and a clean state can always be maintained.

  In the embodiment of the present invention, it is described as a traveling frame device for conveyors particularly suitable for foods, but the application of the present invention is not limited to such applications, and for conveyors that require frequent maintenance. The present invention can be used for a traveling frame device and various traveling frame devices for conveyors that require clean use. Moreover, each structure, material, etc. of the traveling frame apparatus for conveyors of this invention are not restricted to the example of illustration, etc., The design change in the range which does not change the summary of this invention is arbitrary.
