JP-2026075721-A - Transfer device

Abstract

[Problem] To make it easier to move the chutes between downhill and non-downhill positions than before. [Solution] A transfer device 100 transfers an object to be transferred, supplied into a cylindrical body, from bottom to top by the rotation of a screw, and slides the object to be transferred down to a target location from a chute 50 provided at the destination. The chute 50 is configured to be rotatable around a predetermined rotation axis X between a sliding posture P, inclined downward towards the tip and allowing the object to be transferred to slide down, and a non-sliding posture, where the tip is located above the sliding posture P. A reversal position M is set on the trajectory between the sliding posture P and the non-sliding posture. A biasing mechanism is provided that biases the chute 50 to the non-sliding posture if it passes the reversal position M while moving from the sliding posture P to the non-sliding posture, and biases the chute 50 to the sliding posture P if it passes the reversal position M while moving from the non-sliding posture to the sliding posture P.

Description

This invention relates to a transfer device for transporting food raw materials before processing, for example, in a food processing plant. As shown in Patent Document 1, this type of transfer device is configured to transfer food ingredients supplied into a cylindrical body from bottom to top by the rotation of a screw installed inside the cylindrical body, and then slide the food ingredients down to the target location via a chute provided at the destination. This chute needs to be in an inclined position (sliding position) with its tip facing downwards when transporting food ingredients, and in a horizontal position (non-sliding position) when, for example, cleaning the inside of the cylindrical body after transport. The chute is designed to be manually rotated around a predetermined axis, allowing it to switch between these inclined and horizontal positions. However, when changing a chute from an inclined position to a horizontal position, the tip of the chute must be lifted. Depending on the machinery downstream of the transfer device, the chute may be long and heavy, and lifting the tip to a high position can be an difficult task. Furthermore, conventional transport devices are configured so that a locking mechanism engages to maintain the chute in a horizontal position when it is in a horizontal position; however, this locking mechanism must be released when returning the chute to an inclined position. However, this locking mechanism is sometimes located at such a high position that it requires a stepladder to reach, making it difficult to return the chute from a horizontal to an inclined position. Japanese Patent Publication No. 2022-68920 A schematic diagram showing an example of a food processing plant where a transfer device of one embodiment is used.A perspective view showing the overall configuration of the transfer device of the same embodiment.A schematic diagram showing the chute and biasing mechanism in the sliding position of the same embodiment.A schematic diagram showing the chute and biasing mechanism in a non-sliding position according to the same embodiment.A schematic diagram showing the chute and weight in the sliding position of the same embodiment.A schematic diagram showing the chute and weight in a non-sliding position according to the same embodiment.A schematic diagram showing the impact absorbing means of the same embodiment.A schematic diagram showing an auxiliary device of the same embodiment. Hereinafter, an embodiment of the transfer device according to the present invention will be described with reference to the drawings. The transfer device of this embodiment transfers objects in a predetermined direction. For example, it is used in food processing plants to transfer raw food ingredients in a vertical direction (upright direction), and is also referred to as a vertical conveyor (vertical transfer device). As an example of a meat processing plant, as shown in Figure 1, it can be described as having a first device 101, a flake grinder, which cuts frozen block meat into small pieces, and a second device 102, a chopper, which extrudes the ground meat pieces through numerous through-holes formed in a plate. Furthermore, the transfer device 100 in this embodiment is interposed between the first device 101 (flaker grinder) and the second device 102 (chopper) to supply the minced meat discharged from the flaker grinder to the chopper. Furthermore, the use of the transfer device 100 is not limited to those described above. For example, it can be interposed between various first devices 101 and second devices 102 to transfer materials between them, such as grinders, mixers, flakers, and dicers. Also, the source of raw materials to the transfer device 100 is not limited to the device itself; for example, raw materials may be supplied to the transfer device 100 manually. Similarly, the destination of raw materials from the transfer device 100 is not limited to the device itself; for example, it may be a predetermined area such as a container. Specifically, as shown in Figure 1, the transfer device 100 comprises a container 10 for containing the object to be transferred, a cylindrical body 20 to which the object contained in the container 10 is supplied, a screw 30 provided inside the cylindrical body 20, a swivel head 40 provided at the upper end of the cylindrical body 20, and a discharge chute 50 provided on the swivel head 40. As shown in Figures 1 and 2, the container 10 receives the object to be transported from the first device 101, which is located upstream of the transport device 100, and also houses the object. Here, as shown in Figure 2, the container 10 is a box-shaped structure with an open top, and its opposing inner surfaces 11 are inclined to gradually converge towards each other as they move downwards. This allows the object to be transported, supplied through the top opening, to be collected and housed towards the bottom of the container 10. As shown in Figure 2,
