Description

  The present invention is a plastic assembly in which an egg conveyor formed of a chain assembly and a plurality of connecting rods connected to the chain assembly, which allows not only a straight line but also a free curved track, is provided on the support side. It is related with the conveyor assembly for eggs which made it possible to convey eggs gently while sliding on the sliding surface.

  Conventionally, in order to secure the degree of freedom in the transfer direction of egg conveyors, there is a conventional technique in which a chain assembly having a shape combining a highly elastic ring shape is used. In addition, the chain assembly used a long moving surface as a sliding state except for the periphery of the sprocket in order to move in a fluid manner. For example, as can be seen in Patent Document 1 below, the chain is slidably supported by a chain guide member 64 (see FIG. 19).

  However, in a situation where a higher quality egg supply is desired, in a configuration that slides by sliding between metals as described above, there is a probability that there will be a piece of metal generated by rubbing. It cannot be avoided. On the other hand, there is another issue that makes it difficult to obtain the maintenance timing in an environment where the conveyor is operated for a long time. Therefore, stable operation (sliding) of the conveyor is ensured even during a long operation. In addition, there is a demand for a device that lowers the probability of metal rubbing. Furthermore, a structure that can complete maintenance by a simple operation in a short time as desired is desired.

  An egg conveyor assembly as defined in claim 1 includes a chain assembly configured such that a slack can be formed in a length in a connected state, and a egg assembly connected to a part of the chain assembly. A plastic guide comprising an egg conveyor with appropriate gaps and a planar sliding surface for receiving and sliding the load of the chain assembly (5), and having a supporting element with a width smaller than the width forming the sliding surface It is characterized by comprising a rail and a support for receiving and supporting the support element (4b) without swinging.

  Furthermore, the egg conveyor assembly as defined in claim 2 is characterized in that, in addition to the features of claim 1, the support assembly when a downward force is applied to the support element by the load of the chain assembly. It is characterized in that the lower surface of the element and the holder are configured to be in contact with two lines to support the support element.

  An egg conveyor assembly as defined in claim 1 is configured such that an egg conveyor having a gap suitable for receiving eggs is connected to the conveyor, and a slack can be formed in the connected state. The chain assembly is an essential component. With the above configuration, it is a form that is not suitable for a feeding device that is strongly restricted in the longitudinal direction of the chain or the like with respect to the chain assembly, and therefore, a planar sliding surface that receives and slides the load of the chain assembly. It is an essential requirement to have A plastic guide rail having a structural feature including a support element having a width smaller than a width forming the sliding surface, and further supporting and supporting the support element of the plastic guide rail without swinging. It is the invention comprised from the support body. Because of this structure, the egg conveyor does not roll unnecessarily on the appropriate gap, and the loose corners are freed by the chain assembly connected to form slack. The chain assembly is slid by a plastic rail that can be designed freely and that can slide freely even at its loose corners. Also, the egg conveyor connected to the chain assembly inevitably achieves free sliding. In addition, the chain assembly that comes into contact with the plastic guide rail has a configuration in which the rings are repeatedly combined vertically and horizontally, so that the plastic guide rail has a planar and planar sliding surface to support the load. In addition, a configuration is required in which the support portion of the plastic guide rail does not contact the ring on the vertical side of the chain assembly. Therefore, this requirement is achieved by providing a plastic guide rail with a support element having a width smaller than the width forming the sliding surface. By combining the above, it is possible to form a free curve and to achieve smooth sliding even when the load receiving surface and the chain assembly moving in the left-right direction are contacted. In addition, this configuration can provide a configuration that is unlikely to generate the adverse conditions that occur in the conventional metal piece.

According to a second aspect of the present invention, when a downward force is applied to the support element due to the load of the chain assembly, the lower surface of the support element and the holder are in contact with each other by two lines to support the support element. It is composed. As a result, the load of the chain assembly is distributed in two lines, and the stress when swinging in the left-right direction is also distributed to the left and right. It is possible to reduce the probability of breakage due to cracks and the like.
Further, in the above environment, the plastic guide rail is likely to accumulate frictional heat. Heated plastic material softens and promotes aging. In addition to being simply worn away, it may soften and deform, leading to detachment, in which case the plastic sliding surface is lost due to sudden deformation. However, in the present invention in which the plastic guide rail is sandwiched between metal holders, the heat generated by the friction of the plastic guide rail is quickly cooled through the holder. Furthermore, even if the plastic guide rail is softened, it is configured to be sandwiched by a metal holder, and the plastic guide rail sits stably on the holder without depending on the hardness of the plastic material itself. It is possible to continue.
Further, when the plastic guide rail and the holder are in contact with each other with a large contact area as described above, various stresses applied to the plastic guide rail by the contact surface are not received in a partial area, that is, It is possible to make it difficult for cracks to occur in the plastic material.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows a first embodiment, in which (b) schematically shows an overall view of the egg conveyor assembly, and (a) in FIG. 1 is the sample indicated in (b) above. The long 1e portion is shown enlarged.
Further, (a) is drawn narrower than the actual width 1e shown in (b). In addition, the components of the egg conveyor are also drawn short so as to fit the narrowed state. Further, the beam portion 1f in (a) is omitted. The partial shortening or omission described above is merely a drawing technique in drawing creation.
Further, in (a), the left half of the drawing shows an assembled state, and the right half shows the components separated from each other.

FIG. 2 shows the same drawing as FIG. 1A as viewed from below. Further, FIG. 2B is a partially enlarged front view in which the range indicated by the dotted line (b) in FIG. 1A is enlarged, and is shaded so that details of the parts can be understood.
In the above figures, 0 is an egg, 1 is a support, 1a is a side wall, 1b is a beam member (large), 1c is a beam member (small), 1d is a holder (mainly a metal material), 1e is a width, 1f Is a beam member, 2 is a buffer member, 2a is a hollow portion, 2b is a fitting portion, 3 is a connecting jig, 4 is a plastic guide rail, 5 is a chain assembly, 5a is a connecting ring, and 5b is a supporting ring. , 6 is an egg conveyor, 6a is a straight bar, and 6b is a curved bar.

The support 1 is angled with the upper end 1e facing inward, which is on the belt conveyor side, and the beam member 1b (large) projects in the inner direction of the belt conveyor immediately below the support 1 so that the support 1 On the other hand, a cantilever is formed.
Each of the beam members 1b and 1c is provided with holders 1c and 1d, and a plastic guide rail 4 is fitted to the holders 1c and 1d. The relationship between the plastic guide rail and the holder will be described in detail below. First, the plastic guide 4 has a T-shaped schematic cross-sectional shape, the upper surface thereof is provided with a sliding surface 4a, and a support element 4b is provided in the vertical direction. Further, an engagement element 4c formed by a recess is provided at a position slightly below the middle of the support element 4b. Further, the main destination of the load received on the sliding surface 4a is the lower surface 4d immediately below the sliding surface 4a, and the lower surface 4d has two surfaces with the support element 4b interposed therebetween. The holders 1c and 1d on the receiving side include a receiving portion cd1 having a substantially U-shaped inner shape. Furthermore, the holders 1c and 1d have the following configuration in common. That is, it is formed by two wall surface portions cd2 constituting the receiving portion cd1, an engagement element cd3 provided below the middle of the wall surface portion cd2, and a top surface cd4 of the wall surface portion cd2.

As described above, the holder includes a receiving portion cd1 configured to be sandwiched between two wall portions cd2. The inner width of the receiving portion cd1 is substantially the same as the outer width of the support element 4b of the plastic guide rail 4. Furthermore, the engagement element cd3 provided with the protrusion amount and positional relationship which can be fitted with the engagement element 4c with which the support element 4b is provided is provided. The plastic guide rail 4 is pushed into the holders 1c and 1d from above due to the characteristics of the plastic flexible member, so that both the engaging elements 4c and cd3 are fitted and fixed. Alternatively, by inserting the plastic guide rail 4 from the longitudinal direction of the holders 1c and 1d, both the engaging elements 4b and cd3 are similarly fixed in the same manner.
The lower surface of the support ring 5b comes into contact with the plastic guide rail 4 (upper side) fixed as described above, and the support ring 5b can freely slide along the rail direction. Further, the contact range between the support ring 5b and the plastic guide rail 4 is in the range cd5 indicated by the phantom line from the position 5b in FIG. 2B. In the same state, the support ring 5b that contacts on the lower plastic guide rail 4 provided on the extension of the beam member (small) 1c is in contact with the contact surface 5e in FIG. Glide (see partially enlarged view in FIG. 3). The contact surface 5e is configured such that the egg conveyor 6 is configured as an endless belt, and as a result, the contact surface 5e extends over the sliding surface 4a on the lower plastic guide rail 4 with the contact surface 5e in the support ring 5b. Slides in contact.

Now, as described above, the support ring slides on the plastic guide rails 4 in the vertical and horizontal directions (four in total).
Further, the weight corresponding to the number of eggs on the egg conveyor and the force obtained by adding the weights of the straight bar 5c and the curved bar 5d constituting the conveyor are applied to the sliding surface 4a via the support ring 5b. Apply. This load is received by the surfaces cd4 of the two holders 1d through the lower surface 4d of the plastic guide rail 4. Further, the load of the conveyor is also received on the contact surface fitted with the engagement element cd3 and the engagement element 4c, and the load can be received by the contact surfaces in a total of four places (four lines).

  As described above, the downward force due to the load of the conveyor has been described. Further, how the lateral force generated by the shaking of the conveyor or the change of the direction of the conveyor is applied to the plastic guide rail 4 will be described. . First, the lateral vibration is caused by the fact that the position (ro) and (ha) in the connecting ring 5a, which is a component of the chain assembly 5, hits the side surface (ii) and the side surface (e) of the plastic guide rail 4. The shaking stops and the egg conveyor moves along the desired trajectory. This will be described in detail. The swaying of the egg conveyor 6 is swung in both directions (left and right) and (and). With respect to the direction of the rolling (f), in FIG. 2 (b), the surface (f) of the plastic guide rail 4 and the surface (filter) of the connecting ring 5a contact and slide, The egg conveyor 6 operates while the movement stops. With respect to the movement in the opposite direction (and), the movement in the lateral direction is stopped and the egg conveyer is stopped by the completely identical and symmetrical structure shown on the left side of FIG. 1 (a) and FIG. 2 (a). Operate {The structure and action on the opposite side are the same (symmetrical) and will be omitted}.

Returning to the description in FIG. As a condition that the surface (b) of the connecting ring hits the side surface (f) of the plastic guide rail 4, it is necessary to provide a width cd6 of the holder 1d that exceeds the width 4e of the plastic guide rail 4. ing. Therefore, the greater the difference between the two widths, the lower the probability that the connecting ring 5b will hit the side surface of the holder 1d or 1c even when worn. As described above, the above difference should be reasonably large. {Because the force that contacts the side (ni) or (ho) is small compared to the force applied to the sliding surface 4a, there is an extremely large margin. Is a waste of material and is not preferred for enlarging the beam shape}.
Thus, the structure which the egg conveyor 6 with which the chain assembly 5 was equipped can operate | move smoothly with respect to the support body 1 was shown. The buffer member 2 is a buffer member for preventing the egg 0 from spilling to the side of the egg conveyor.

  Since the plastic guide rail 4 configured as described above is only inserted and fixed to the holder 1d, the plastic guide rail 4 can be easily detached without using any special adhesive means such as an adhesive or heat welding. As described above, it is possible to receive the downward force generated by the egg conveyor by distributing the force with the four muscles in the structure.
