Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pot lid transfer device used in an automatic rice cooking system in which rice and seasonings are put into a pot to automatically cook rice.

[0002]

[Prior art]

 With the increase in demand for instant foods, it is necessary to develop a device for continuously cooking a large amount of rice, such as chirashi rice, and in order to respond to this, the present applicant has disclosed such a device in Japanese Patent Laid-Open No. 61-170414. We proposed an automatic rice cooking system. This rice cooking system is a system that puts rice and seasonings into the pot to cook them, then steams them, removes them from the pot, and loosens them. A mechanism as shown in Fig. 4 is used as a device for covering the lid, removing the lid from the pot after steaming after cooking rice.

In this device, a center of a U-shaped hook a hooked on a handle of a lid is pivotally supported on a lower end of an elevating rod b by a fulcrum pin c, and this is rocked upward and downward by a cylinder d. It was made to place. However, in such a device, the lid pulled up by the hook a does not have any fixing means. Therefore, the lid is lifted, moved, and lowered to a predetermined position, which causes a positional shift. It causes a problem that it cannot be set in position.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of such a problem, and an object thereof is to provide a new device capable of securely holding and replacing the lid without applying an excessive force to the device. To provide.

[0005]

[Means for Solving the Problems]

 That is, the present invention is, as an apparatus for transferring a lid of a pot in an automatic rice cooking system for achieving such a problem, attaching a pressing pad to four corners of a member driven by a driving means and moving up and down. A guide rod is fixed horizontally to the guide rod, and a pair of gripping arms are slidably mounted on the guide rod so as to be spaced apart from each other and driven by a driving means, and the lower ends of these gripping arms are engaged with a lid handle. The hooks are attached so that they face each other.

[0006]

【Example】

 Therefore, the embodiment illustrated below will be described. The drawings show an embodiment of the present invention. In the figure, reference numeral 1 is a main frame that stands upright behind a steaming processing unit (not shown) so as to straddle the transfer conveyor 40 of the pot 30 and the discharge conveyor 45 of the lid 35, and moves to the upper girder 2 of the main frame 1. A rodless cylinder 4 for operation is provided laterally, and a lid removing unit 10 is attached to a movable portion 5 thereof so as to be movable between a kettle transfer conveyor 40 and a lid transfer conveyor 45.

The hook removing unit 10 is roughly composed of a suction gripping mechanism 20 of a lid 35, and a lift drive cylinder 13 for moving the lift up and down, and is attached to the movable portion 5 of the moving operation rodless cylinder 4. On the supporting frame 11, an elevating and lowering drive cylinder 13 connected to an elevating and lowering plate 21 via a rod 14 is erected, and on both sides of this, a guide sleeve 1 for guiding the guide rods 17, 17 on the elevating and lowering plate 21. 6 and 16 are provided upright and configured to move up and down a suction gripping mechanism 20 described later.

On the other hand, the elevating plate 21 described above has a substantially same rectangular shape as the lid 35, and rods 22 having pressing pads 23 attached to the lower ends are urged downward by the expanding springs 24 at the four corners. The support plate 25 is slidably attached in a fixed state, and at the center of the ascending / descending plate 21, two support plates 25, 25 are provided upright with a space therebetween. A pair of gripping arms 28, 28 each having an inward hooking piece 27, 27 attached to its lower end is slidably inserted into a guide rod 26 provided horizontally between the support rods 25. A pair of arm drive cylinders 29, 29 provided laterally on the drive unit 25 are arranged so that they can be separated from each other and approach each other.

In the apparatus configured as described above, when the pot 30 that has undergone the steaming process is sent to the lid transfer device, it is preliminarily placed on the conveyor by the rodless cylinder 4 for moving operation. The shuttle removal unit 10 that has been moved and is on standby first extends the rod 14 of the lifting drive cylinder 13 to lower the suction gripping mechanism 20 on the lifting plate 21 onto the lid 35.

As a result, the pressing pads 23, etc. first come into contact with the four corners of the lid 35, and the lid 35 is firmly held while being pressed by the expansion spring 24 due to the subsequent lowering of the lifting plate 21. To do.

On the other hand, when it descends to this position, the hooking piece 27 at the lower end of the gripping arm 28 also reaches the handle 36 of the lid 35, and a position detection sensor (not shown) detects this and the detection signal thereof. The pair of arm drive cylinders 29, 29 is operated to extend the rod to bring the pair of gripping arms 28, 28 closer to each other, and the hooking pieces 27, 27 at the lower ends thereof are engaged with the handle 36.

Then, in this state, when the lifting / lowering drive cylinder 13 is operated in the opposite direction to pull up the gripping mechanism 20, the lid 35 on the shuttle 30 acts vertically on the lower surface of the handle 36. The hooking pieces 27, 27 are lifted upward and the pressing force of the pressing pads 23 that act on the four corners of the surface are fixed and lifted horizontally, and the whole is taken out from the hook 30 and then rodless. It is transferred onto the discharge conveyor 45 by the cylinder 4 and placed on it by the action opposite to that in the previous case.

[0013]

[Effect of device]

 As described above, according to the present invention, the pressing pads are attached to the four corners of the elevating member, and the pair of grasping arms are attached to the horizontal guide rods fixed to the elevating member so as to be spaced apart from each other. Since the hooking pieces are provided at the lower end of the lid so as to face each other, the gripping arms can be engaged with the handles of the lid while pressing the four corners of the lid with the pressing pad, and the position shift can be generated while fixing this. It is possible to move to a predetermined position without being placed and to mount it, so that the reliability of the apparatus can be further enhanced.
