Description

[Detailed description of the invention] The present invention is a conveyance moving device that is propelled by a pusher provided on a drive check 7, and in particular, a pusher engagement dog that can freely move away from the pusher and a pusher engagement dog of a subsequent moving device. Regarding a storage-enabled transport device equipped with an operation piece for stopping a subsequent moving device that moves a dog to a non-engaging position with respect to a pusher, it is possible to drive the dog backwards using a similar pusher, and also to provide a similar storage function when driving backwards. The purpose is to enable them to demonstrate their abilities.

An embodiment of the present invention will be described below based on illustrative drawings.
The illustrated transportation moving device 1 includes a first truck 2 to a fourth truck 5.
The first truck 2 and the second truck 3, and the third truck 4 and the fourth truck 5 are connected by connecting rods 6 and 7, respectively, and the second truck 3 and the third truck are connected by connecting rods 6 and 7, respectively. The trolley 4 is equipped with support stands 9 and 10 for supporting the transported object 8, and these support stands 9 and 1.
0 are connected by a connecting rod 11.

Each of the above-mentioned carts 2 to 5 is equipped with a horizontal axis roller 13 that fits into a pair of left and right guide rails 12, and a vertical axis roller 14 for steady rest that is close to the inside of the guide rail 12, and is supported and guided by the guide rail 12. You can move along a fixed route.

The first cart 2 and the fourth cart located at both the front and rear ends of the moving device 1
The trolley 5 has a pusher engagement dog 16, 18 that can freely move in and out of the pusher, and stop operation pieces 19 and 20 that switch the dog to a non-locked position with respect to the pusher, which are arranged side by side at symmetrical positions on the front end. The pusher engaging dogs 16, 18 are each pivotally connected to the horizontal shafts 15, 17 so as to be able to swing upward against gravity, and are provided with pusher engaging recesses 16a and 18a, and cam surfaces 16b and 18b that are inclined obliquely upward are provided at the distal end portions.

When the two transport moving devices 1 approach each other,
Each stopping operating piece 19.20 located at mutually close ends of the circular displacement device 1 engages the cam surface 16b of the corresponding plusher engagement dog 16.18 of the mating displacement device 1.

18b to move these dogs 16.18 upward to a disengaged position relative to the pusher.

The forward direction of the transport moving device 1 is the direction indicated by the arrow 21, and therefore the dog 16 is referred to as a forward pusher engagement dog, and the dog 18 is referred to as a reverse pusher engagement dog. Reference numeral 19 is referred to as an operation piece for stopping the subsequent moving device when moving forward, and operation piece 20 for stopping is called an operation piece for stopping the following moving device when moving backward.

In the conveyance path for driving and propelling the conveyance moving device 1 in the forward direction 21, a guide rail 24 that guides a trolley 23 provided with a pusher 22 is connected to the pusher 22 as shown in the figure.
The position is shifted to the left with respect to the moving path center of the moving device 1 so that it can engage with the forward pusher engagement dog 16 on the left side of the front end of the moving device 1.

The pusher trolley 23 is coupled to a drive chain 725.

26 is a trolley that supports the drive chain 725 at an intermediate position.

When the drive chain 725 is rotated to drive the pusher 22 in the forward direction 21, the pusher 22 automatically engages the recess 16a of the forward pusher engagement dog 16 from behind, and the moving device is moved through the dog 16. 1 is driven and propelled in the forward direction 21, and the supported object 8 is transported in the forward direction 21.

In addition, at a predetermined location, the dog 16 is moved upward and removed from the pusher 22 using a movable stopper (not shown) using its cam surface 16b, and the stopper is brought into contact with an appropriate position on the dog 16 or the first truck 2. The moving device 1 can be stopped by moving the moving device 1.

Furthermore, when the subsequent moving device 1, which is similarly driven by the pusher 22, approaches the stopped moving device 1 within a certain distance, the rear end of the stopped moving device 1 is moved as shown in FIG. 4A. Since the operating piece 19 located at the rear portion moves the dog 16 at the front end of the succeeding moving device 1 upward and removes it from the pusher 22, the first truck 2 is automatically stopped in contact with the fourth truck 5.

In this way, the moving device 1 is sequentially and automatically stopped by the action of the operation piece 19, and is stored.

At this time, the operation piece 20 at the front end of the subsequent moving device 1
moves upward the backward pusher engagement dog 18 located at the rear end of the stop/move device 1, but since this dog 18 is in an idle state, no response effect occurs.

In the conveyance path for driving and propelling the conveyance moving device 1 in the backward direction, as shown by the imaginary line in FIG. The pusher 28 is the moving device 1
The position may be shifted to the right with respect to the center of the moving path of the moving device 1 so that it can engage with the backward pusher engaging dog 18 on the right side of the rear end.

When the pusher 28 is driven in the backward direction 27 by the driving chain 731, the pusher 28 automatically engages with the recess 18a of the backward pusher engagement dog 18, thereby driving and propelling the moving device 1 in the backward direction 27. .

The stopping of the moving device 1 moving in the backward direction 27 by the stopper, the automatic stopping of the subsequent moving device 1, and the like are also achieved by the action of the backward pusher engagement dog 18 and the operation piece 20 for stopping the subsequent moving device when moving backward. (see FIG. 4B) in exactly the same way as when moving forward.

According to the conveyance moving device of the present invention, it is possible to drive and propel the vehicle in both the forward and reverse directions by simply considering the position of the pusher movement path, and in both cases, automatic stopping and movement are possible.
Since it has a storage function, it can be used very conveniently.

For this reason, it is now possible to use a traverser or the like to move the moving device parallel to the return path instead of making a U-turn on the moving path in the past.
Even when transporting a long object, the area occupied by the turn section of the moving device can be reduced and the efficiency of use of the factory floor can be improved.

In order to obtain the above-mentioned effects, for example,
Like the device described in Japanese Patent No. 46480, sensors connected in conjunction with pusher engagement dogs are provided at the front and rear of the moving device, and if these sensors move due to a collision with the preceding stop moving device, the movement of the sensor It can be constructed so that the pusher engagement dog on the forward direction side is switched to the non-holding position in conjunction, but there is also a sensor that is movable separately from the pusher engagement dog and the movement of this sensor is transmitted to the pusher engagement dog. A movement mechanism is required to do this, making the structure extremely complex.

Furthermore, if the movement of the sensor or the interlocking mechanism is impaired, it will no longer be possible to perform the intended action, so it is necessary to perform sufficient maintenance and inspection of the movable parts.

However, according to the configuration of the present invention, there is provided a transportation moving device consisting of a plurality of carts movable along guide rails, and the pusher engaging dog, which is movable in disengagement with respect to the pusher, serves as the carts located at both the front and rear ends. Two carts with a stop operation piece for switching the dog to a non-engaging position with respect to the pusher are arranged side by side at symmetrical positions on the front end, and the two carts are arranged with their front and back directions reversed, so that the two transport moving devices are connected to each other. When approached, each stopping operation piece located at the mutually approaching ends of the circular moving device imparts a disengagement movement relative to the pusher to the corresponding pusher engagement dog of the mating moving device, so that during the storage operation, the above-mentioned The operation piece can directly operate the pusher engagement dog of the subsequent moving device to release the drive, and of course, the operation piece can also be composed of a fixed cam-like protrusion, so there are no movable parts other than the pusher engagement dog. It can be implemented in an extremely simple structure without any problems.

Therefore, a good storage function can be ensured at all times without paying attention to maintenance and inspection.

Furthermore, according to the configuration of the present invention, by using one type of small trolley in which pusher engagement dogs and stop operation pieces are arranged symmetrically side by side, it is possible to transport an arbitrary length depending on the length of the object to be transported. The transfer device can be easily constructed, and the transfer device can reliably perform a storage function that automatically stops the following transfer device in the vicinity of the preceding stop and transfer device regardless of whether it is moving forward or backward. It can be conveniently used as a mobile device.

Although the moving device is shown as one in which four carts support the transported object from below, the present invention is not limited to this, and any structure may be used.
