[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrier for reciprocatingly driving along a vibrating direction in which a forward side of the carrying direction is higher, and for carrying a loaded article in the carrying direction, and the carrier. Is attached to the upper part, and a main body is provided for reciprocatingly driving the carrier along the vibration direction. The main body is fitted to the carrier and the main body in a state where their relative movement in the left-right direction is prevented. The fitting part to be fitted is provided so as to be freely detachable,
A vibratory transport provided with a toggle-type fastener mounted between the transporter and the main body to clamp and hold them in a state where relative movement in the front-rear direction and the vertical direction is prevented. Related to the device.

[0002]

2. Description of the Related Art The above-mentioned vibration type transport apparatus is used, for example, in a granular material inspection apparatus when a granular material to be inspected is transported as a conveyed object placed thereon. A box-shaped carrier with an open front side is mounted on the upper part of the main body configured to be electromagnetically driven, and the carrier is reciprocated along a vibration direction in which the forward side is higher toward the front side in the transport direction. The inspection object placed on the carrier is transported and supplied to the inspection unit.

[0003] With the above-mentioned use, fine powder of the conveyed object and other dusts adhere to the inner surface of the conveyed body, so that it is necessary to remove the conveyed body from the main body and clean it. Since it is desirable that the body can be easily attached to and detached from the main body, an attachment / detachment structure as shown in FIG. 13 has been considered. More specifically, a pair of V-shaped downward receiving surfaces 41a and 41b are provided on the side of the transport body 41, and the pair of downward receiving surfaces 41a and 41b are received on the main body 40 side. V
A pair of groove-like upward receiving surfaces 40a, 40b are provided, and the downward receiving surfaces 41a, 41b are connected to the upward receiving surfaces 40a, 40b.
In the state that the two are received at b, the relative movement in the front-rear direction (transport direction) and the vertical direction is prevented.
The carrier 41 and the main body 40 are joined by being tightened by a pair of toggle-type fasteners 42 mounted between the carrier 41 and the main body 40 in two positions before and after in a vertical direction. On the other hand, when removing, use the toggle-type fastener 4
2 is loosened so that the carrier 41 can be separated from the main body 40.

That is, in the above-mentioned vibration type transport apparatus, when the apparatus is vibrated in the forward direction (forward direction in the transport direction) in the vibration direction (indicated by an arrow in FIG. 13), the rear upward receiving apparatus is mainly used. The surface 40a is the downward receiving surface 41 on the rear side.
In this movement toward the forward movement side, the force that the carrier 41 tends to separate from the main body 40 does not act so strongly. Conversely, when the vibration is driven in the backward direction in the vibration direction (the rear side in the transport direction), the upward receiving surface 40b mainly on the front side is mainly the downward receiving surface 41 on the front side.
b is depressed, but in the case of this backward movement, the upward receiving surface 40b and the downward receiving surface 4
Since the shape of 1b is an inclined shape which is located closer to the backward movement side in the above-mentioned vibration direction as the shape is lower, the force of the carrier 41 to move upward from the main body part 40 with the above-described vibration drive on the backward movement side is strong. work. Therefore, it is necessary to tighten the transporting body 41 and the main body 40 with a relatively strong force so as not to be separated by the toggle-type fastening tool 42.

[0005] Although not shown in the figure, in the above-mentioned vibration type transport apparatus, for example, the transport body 41 is used as a fitting portion for preventing the relative movement of the transport body 41 and the main body 40 in the left-right direction. A pair of right and left vertical plate-shaped fittings each having a fitting surface along the front-rear direction on the lateral outer surface is provided on the bottom surface side of the body portion 40.
And a pair of right and left fitting bodies each having a fitting surface that fits from the outside with the fitting surfaces of the pair of vertical plate-like fitting bodies.

[0006]

However, in the above-mentioned vibration type transport apparatus, in order to prevent the transport body 41 from being separated from the main body 40, the toggle type fastener 42 is held in a vertical position. Since it is mounted between the carrier 41 and the main body 40, it is necessary to provide a wide space for the arrangement of the fasteners 42 in the vertical direction. There was a problem that it was difficult to configure compactly.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to solve the above-mentioned disadvantages of the prior art by allowing a carrier to be easily attached to and detached from a main body, and to be compact. Another object of the present invention is to provide a vibrating transfer device that can be configured as described above.

[0008]

According to the present invention, a downward receiving surface is provided on the carrier, and an upward receiving surface for receiving the downward receiving surface is provided on the main body.
A front surface facing the front side in an orthogonal posture orthogonal to the vibration direction or an inclined posture positioned on a forward movement side in the vibration direction toward the lower side is provided on the transport body, and a rear surface in a posture corresponding to the front surface. A rearward facing surface is provided on the main body, and the toggle-type fastening tool is mounted between the transport body and the main body in a horizontal direction or a substantially horizontal direction, and the rearward surface and the forward facing It is configured to be tightened in a direction to bring the surface closer.

In other words, when the vibration is driven in the forward direction in the vibration direction, the downward receiving surface on the side of the transport body and the upward receiving surface on the main body side receiving and pushing up and moving forward in the vibration direction. In the meantime, a frictional force acts to prevent the transport body from moving to the backward side in the vibration direction, and the toggle type fastening tool is used to position the carrier in a perpendicular position perpendicular to the vibration direction or as the lower side is positioned on the forward side in the vibration direction. The front surface provided on the transport body in a state of going forward in an inclined posture, and the rear surface provided in the main body in a state of going rearward in a posture corresponding to the front surface is held so as not to be separated. Retention works. Then, by the frictional force and the holding force of the fastener, the carrier and the main body are moved to the forward side in the vibration direction in a state of being coupled.

On the other hand, when the apparatus is driven to vibrate in the backward direction in the vibration direction, the forward surface provided on the side of the transfer body in an orthogonal posture orthogonal to the vibration direction or in an inclined position closer to the forward movement side in the vibration direction as it goes down. , By a rearward surface provided on the main body side in a posture corresponding to the frontward surface, is pushed straight along the vibration direction, or is pushed obliquely downward from the vibration direction, and the downward receiving of the carrier body is performed. The surface is received by the upward receiving surface on the main body side, and moves to the backward movement side in the vibration direction in a state where the carrier and the main body are connected. And, in the vibration drive to the backward movement side, since the carrier and the main body relatively move in a direction in which the holding force of the fastener is loosened, the holding force of the fastener is not so large in the connection between the carrier and the body. Not necessary.

Therefore, the carrier can be easily attached to and detached from the main body by tightening and releasing the tightening by the toggle-type tightening tool, and as described above, the vibration on the forward movement side in the vibration direction can be achieved. In driving, the frictional force acting between the downward receiving surface of the transport body and the upward receiving surface of the main body, and the holding force of the fastener mounted between the transport and the main body cause vibration. In the vibration drive on the backward movement direction, the forward facing surface of the transport body is pushed rearward by the rearward face of the main body portion, and the downward receiving surface of the transport body that has moved downward moves to the upward receiving surface of the main body portion. The carrier and the main body can be coupled to each other by the receiving action that is received and the toggle type fastening tool is mounted between the carrier and the main body in a horizontal direction or a substantially horizontal direction. So
It is possible to minimize the space in the vertical direction for the arrangement of the fasteners as much as possible, so that the carrier can be easily attached to and detached from the main body, and the vibration type can be made compact. A transport device is obtained.

According to a second aspect, in the first aspect, two pairs of upper and lower receiving portions each including the downward receiving surface and the upward receiving surface are provided at an interval in the front-rear direction, and the rearward facing surface and the frontward facing surface are provided. One set of the front and rear receiving portions consisting of
It is provided between the front and rear of the pair of upper and lower receiving parts.

That is, as illustrated in FIG. 7, when the vibration is driven in the forward direction (the left side in the figure) in the vibration direction (indicated by an arrow in the figure), the front surface 32b
Downward receiving surfaces 31a and 32a provided at an interval in front and rear with the body facing the rear surface 3a on the body 18 side.
By the upward receiving surfaces 33a and 34a provided at an interval in the front and back with 3b interposed therebetween, the receiving member is pushed up at two locations spaced apart in the front and rear, and the transport body 9A is moved to the forward side in the vibration direction. . On the other hand, when the vibration is driven to the return side (the right side in the figure) in the vibration direction, the front surface 32b on the side of the transport body 9A is straightened along the vibration direction by the rear surface 33b on the main body portion 18, or The carrier 9A is pushed in a direction downward from the vibration direction to move the carrier 9A to the backward movement side in the vibration direction, and the carrier 9A has a downwardly facing front cover 32b spaced forward and backward with the front surface 32b therebetween. The receiving surfaces 31a and 32a are received at two places spaced apart in the front-back direction by the upward receiving surfaces 33a and 34a that are spaced apart in the front-back direction with the rear-facing surface 33b interposed on the main body 18 side.

Therefore, in any of the forward and backward vibration driving in the vibration direction, one set of the front and rear receiving portions including the rearward surface of the transporting body and the frontward surface of the main body is interposed therebetween. Since two sets of upper and lower receiving portions each including a downward receiving surface on the body side and an upward receiving surface on the main body portion are provided at an interval in front and rear, and the transport body is received by the main body portion by the two sets of upper and lower receiving portions. For example, in the case of receiving by a pair of upper and lower receiving portions, the vertical driving is likely to occur between the transporting body and the main body, but the vibration driving can be performed in a state where the vertical driving is suppressed. Thus, suitable means for implementing claim 1 can be obtained.
