Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention mainly relates to a power conveyor having a sorting device that can be effectively used for quality control for the purpose of removing and sorting nonconforming products such as defective products in a product manufacturing process or a shipping process.

[Prior art]

 2. Description of the Related Art Conventionally, in a product manufacturing process or a shipping process, a sorting device is operated by an electric signal from a detection unit that recognizes a nonconforming product such as a defective product. These are those that guide the nonconforming product to the side end of the transport device by a rotating arm that moves the transport surface of the transport device such as a conveyor horizontally, or that use a damper method to remove the nonconforming product from the front of the transport device. A damper is placed at the rear to remove the non-conforming product on the transport device by dropping it, or to remove the non-conforming product by blowing it off with air. The properties of the product (shape, size, weight, Equipment, etc.) and the circumstances of the process.

[Problems to be solved by the invention]

 However, each of the above-described conventional sorting apparatuses has a drawback and is selected according to the application. However, problems are likely to occur depending on the properties of the sorted products and various circumstances of the process. More specifically, in the case of a sorting device in which a non-conforming product is removed by blocking a conveying surface by a rotating arm disposed on a conveying surface of a conveyor, when a non-conforming product is conveyed, an electric detection from an external detection unit is performed. The mechanism receives the signal and uses the piston movements of the air cylinder and hydraulic cylinder to operate the rotating arm to shut off the transfer surface horizontally and diagonally with respect to the transfer direction for a certain short period of time. Since the conveyor at this time is in operation without stopping, the non-conforming product first hits the rotating arm, and then moves along the swivel arm that is obliquely cut off at the specified side end of the conveyor. Non-conforming products are sent to and sorted. In this case, the nonconforming product depends on the transport position of the nonconforming product (whether it is at the center or the end of the conveyor width) or the properties of the selected product (shape, size, weight, hardness, etc.). The frictional force between the non-conforming product and the conveyor generated when the rotating arm is blocked by the rotating arm, and the frictional force between the non-conforming product and the rotating arm generated when trying to shift on the conveyor at an angle However, it may not be possible to quickly and reliably sort and remove the end of the conveyor at a predetermined end, which may adversely affect the sorting of subsequent sorted products. In the case of the damper method, sorted products are mainly relatively small or light ones, and are often sorted by a shooter. The method of blowing out and removing nonconforming products by air blowing is limited to the case where the number of selected products is light. Another drawback is that the direction in which the sorted products are blown off cannot be determined depending on the location of the air.

[Means for Solving the Problems]

 According to the present invention, the piston rod of a cylinder is placed on a conveyor in which reversing rollers that rotate while engaging with the endless belt are arranged at predetermined intervals on an endless belt provided between a driving roller driven by an electric motor and a driven roller. The knuckle part is fixed to the knuckle part, the rotating member is rotatably held on the knuckle part, the rotating shaft is held by the rotating member, and the sorting bar is fixed to the rotating shaft at predetermined intervals. The object of the present invention is to solve the above-mentioned problem by providing a power conveyor with a sorting device arranged so that a sorting bar is arranged between respective reversing rollers.

[0005]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. According to the present invention, as shown in FIG. 1, a general belt conveyor having an endless belt 10 spanned between a driving roller 7 driven by an electric motor 11 and a driven roller 8 is provided with the following mechanism. It is a thing. On the endless belt 10 on the conveying surface of the belt conveyor, reversing rollers 9 that rotate while engaging with the endless belt 10 are arranged at predetermined intervals. Attach the cylinder 2 to the lower part of the conveyor base at a predetermined position so that the support part rotates, and fix the knuckle part 4 to the tip of the piston rod 3 of the cylinder 2 and fix one end of the sorting bar 1 at a predetermined interval. The rotating shaft 6 held by the rotating member 5 and the device in which the rotating member 5 and the knuckle portion 4 are rotatably held are arranged between the respective reversing rollers 9 with the respective sorting bars 1. As described above, the rotating shaft 6 is pivotally supported at a predetermined side end of the conveyor gantry. In this case, the positional relationship between the reversing roller 9 and the sorting bar 1 is set so that the height of the sorting bar 1 is slightly lower than the reversing roller 9 so that the sorted commodities to be conveyed do not contact the sorting bar 1 in normal times. Also, the sorting bar 1 and the reversing roller 9 are brought close to each other. In the above description, as shown in FIG. 2, the case where the rotating shaft 6 to which the sorting bar 1 is fixed is arranged at one end of the conveyor to sort the conforming product and one type of non-conforming product has been described. As shown, when the rotating shaft 6 to which the sorting bar 1 is fixed is disposed at both ends of the conveyor, a suitable product and two types of non-compliant products can be selected. Next, the operation will be described. With the position of the piston rod 3 of the cylinder 2 raised, as shown in FIG. 4, the sorting bar 1 is in a fixed position (a position parallel and slightly lower than the reversing roller and close to the reversing roller), and as shown in FIG. When the position of the rod 3 is moved downward, the other end of the sorting bar 1 is inclined upward about the connecting portion between the knuckle portion 4 and the rotating member 5 as an axis. The type of the cylinder 2 and the shape and positional relationship of the knuckle part 4 and the rotating member 5 are adjusted and set so that the non-conforming product operates in a moderately inclined state such that it slips off. When the nonconforming product is positioned on the conveyor, the conveyor receives an electric signal from the external detection unit (the power conveyor with a sorting device of the present invention does not have a detection unit), and the conveyor stops. When the piston rod 3 operates downward, the knuckle portion 4 and the shaft portion of the rotating member 5 are pulled downward, and as a result, the rotating shaft 6 held by the rotating member 5 rotates counterclockwise. (30 to 45 degrees), the other end of the sorting bar 1 is inclined upward, and the non-conforming product on the reversing roller 9 slides down along the inclined sorting bar 1 and is removed at the conveyor side end. . Next, since the piston rod 3 of the cylinder 2 operates upward, and the knuckle portion 4 and the shaft portion of the rotating member 5 are pushed up, the rotating shaft 6 held by the rotating member 5 rotates clockwise. (30 to 45 degrees), the other end of the sorting bar 1 operates downward, and the sorting bar returns to the home position, and at the same time, the conveyor operates to sort the following sorted products.

[Effect of the invention]

 The conveyor with a sorting device according to the present invention is provided especially in conjunction with a metal detector, and has been devised for the purpose of sorting and removing contaminating products in a food manufacturing process and a shipping process. A conventional sorting apparatus generally operates a rotating arm horizontally on a conveyor to guide a selected product by the rotating arm and sort and remove the goods. However, in the case of a soft sorted product, the movement of the conveyor and the rotating arm is involved, so that the sorted product hitting the rotating arm is crushed and cannot be properly guided by the rotating arm. In some cases, it may be in a stagnant state and cannot be quickly and reliably sorted and removed. The present invention sorts and removes selected products located on the sorting bar by inclining the sorting bar and sliding them off, thereby achieving the purpose quickly and reliably.
