Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a method for propelling a conveying moving device movably supported on a guide rail by a pusher of a drive trolley that moves along a moving path of the moving device. The present invention relates to a drive mechanism of a conveyance moving device configured to move.

(Prior Art) In the above drive mechanism, the pusher is installed at the rear end of each moving device so that each moving device can be stopped and stored without stopping the drive trolley in the storage path. In addition to providing a pusher operation section for switching to a non-engaging position, a checker is provided on the front side of the pusher to prevent the moving device from moving ahead of the pusher on the drive trolley side, for example, on a downhill path. A device equipped with a movable member is known.

However, when the non-return movable member is configured integrally with the pusher, when the engaged pawl on the moving device side pushes down the non-return movable member and passes relative to it, the pusher also takes the non-engaged position at the same time. Therefore, when the pusher speed is high, there is a risk that the pusher returning to the engaged position will not reliably engage with the engaged pawl on the moving device side.

In order to solve this problem, for example, as disclosed in the micro film of Utility Model Application No. 122165/1983 (Utility Model Application No. 108956/1983), the engaging claw is provided on the drive trolley side. A movable pusher for pushing back, and a movable check member that sandwiches the engaged claw between the movable pusher are separately pivotally supported so as to be swingable up and down, and the movable pusher is provided with a movable member that holds the engaged claw and An operated part that does not engage is provided in series, and a pusher is provided at the rear end of the transport moving device to swing the movable pusher to a non-engaged position in which the movable pusher is disengaged from the engaged claw via the operated part. A drive mechanism equipped with an operating section was considered.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional mechanism, the movable pusher and the movable check member are completely independent with respect to each up-and-down rocking movement, and in the storage path, the When the movable pusher is switched to the non-engaging position by the pusher operating portion of the stop and move device, the check movable member is also caused to fall and swing by the pusher operating portion.

Therefore, when the drive trolley passes through a storage path where a large number of moving devices are stopped, the movable check member intermittently collides with the pusher operating portion of each moving device, which not only increases noise but also , the operated surface portion of the non-return movable member is likely to be damaged, leading to a decrease in durability.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an engaged claw at the front end of a transport moving device,
On the drive trolley side, a movable pusher for backing up the engaged pawl and a movable non-return member for sandwiching the engaged pawl between the movable pusher are each separately pivotably supported so as to be able to swing up and down. , the movable pusher and the non-return movable member are connected with a weight portion that urges and holds them in an engaging posture with the engaged claw;
The movable pusher is provided with an operated part that does not engage with the engaged claw, and the movable pusher is connected to the engaged claw via the operated part at the rear end of the conveying moving device. In a drive mechanism provided with a pusher operation section that swings the pusher to a non-engaged position where it is released from the non-return position, the weight part of the movable member for non-return is arranged above the weight part of the movable pusher, and the weight part of the movable member for non-return is disposed above the weight part of the movable pusher; The present invention proposes a drive mechanism for a transportation moving device in which the operated surface of the movable member is moved further back than the operated surface of the operated section.

(Operation of the invention) According to the above configuration, when the movable pusher engages with the engaged claw on the moving device side, the non-engaging claw relatively kicks the operated surface of the check movable member. However, at this time, the movement of the movable check member is not transmitted to the movable pusher, and the movable pusher remains in the upright engaged position. Therefore, even if the speed of the drive trolley is high, the movable pusher can reliably engage the engaged pawl on the moving device side.

In addition, in the storage path, the pusher operating section of the moving device that is stopped in advance switches the movable pusher, which is propelling the following moving device, to a non-engaged posture via its operated section, so that it is not engaged. It is possible to automatically stop the following moving devices in sequence by separating it from the mating claw, but when the movable pusher is swung to the non-engaged position by this pusher operating section, the biasing weight section of the movable pusher is Due to the upward movement, the biasing weight portion of the movable non-return member is pushed up, and the movable non-return member is also automatically caused to fall and swing. Of course, since the operated surface of the non-return movable member is retracted from the operated surface of the operated portion of the movable pusher, the pusher operating portion is moved before the operated surface of the non-return movable member. It does not come into contact with.

Therefore, when the drive trolley passes under a large number of stationary moving devices in the storage path, the movable non-return member is kicked relative to the engaged pawl of each moving device. , the user will no longer be kicked by the pusher operation section.

(Example) An example of the present invention will be described below based on the attached illustrative drawings.

In FIGS. 1 to 3, reference numeral 1 denotes a drive trolley, which is movable to a pair of left and right guide rails 3 via a pair of left and right supporting horizontal shaft wheels 2 that are pivotally supported at two locations, front and rear. It is supported and connected to the drive chain 4. Reference numeral 5 denotes a movable pusher, whose middle part is supported by a horizontal horizontal shaft 6 on the upper front end of the drive trolley 1 so as to be able to see-saw. An engaging portion 7 is formed, and a weight portion 8 is formed at the opposite end for biasing the movable pusher 5 into the engaging position shown in FIG. Reference numeral 9 denotes a stopper against which the weight portion 8 comes into contact, and is made of an elastic body such as rubber, and is held by the drive trolley 1. 10
2 are a pair of left and right operated portions which are provided upwardly protruding near the pivot portion of the movable pusher 5, and have a sawtooth side surface shape with a slope 10a facing diagonally forward and upward. 11 is a movable member for check,
In a recess 12 formed in the movable pusher 5 at an intermediate position between the pair of left and right operated parts 10, the intermediate part is pivotally supported by the horizontal horizontal shaft 6 for seesaw movement, and faces diagonally forward and upward. Slope 11
The leading end following a (rear end in terms of the direction of movement) 1
1b is formed so as to be substantially flush with the upper end surface and rear vertical surface of the operated section 10 when viewed from the side, when in the engagement posture shown in FIG. A weight portion 13 is formed that urges the engaging position. This weight portion 13 comes into contact with a stopper portion 14 formed on the movable pusher 5.

In FIGS. 4 and 5, reference numeral 15 denotes a trolley located at the front end of a plurality of front and rear trolleys constituting the transportation moving device, and is connected to trolley No. 2 by a connecting rod 16. Reference numeral 17 denotes a trolley located at the rear end of the plurality of front and rear trolleys constituting the transport moving device, and is connected to the front trolley by a connecting rod 18. Each of these trolleys 15 and 17, together with other trolleys, has supporting horizontal shaft wheels 2 that are respectively fitted into a pair of left and right guide rails 19 installed along the guide rail 2 that guides the drive trolley 1.
0, 21 and vertical shaft wheels 22, 23 for steady rest
The front end trolley 15 has an engaged claw 24,
The rear end trolley 17 has a pusher operating section 2.
5 are provided respectively.

The engaged pawl 24 resists the urging force of the weight part 13 only by the movable check member 11 without interfering with the pair of left and right operated parts 10 of the movable pusher 5 provided on the drive trolley 1. It is formed into a small width that can be pushed backward and downward, and has a side surface shape that can be engaged with the hook-shaped engaging portion 7 of the movable pusher 5. As shown in FIG. 2, the weight portion 13 of the movable check member 11 is disposed above the weight portion 8 of the movable pusher 5, and the weight portion 13 of the movable check check member 11 is disposed above the weight portion 8 of the movable pusher 5. The slope 11a, which is a surface, is set back from the slope 10a, which is the operated surface of the operated portion 10 of the movable pusher 5. or,
The lower surface of the pusher operating portion 25 is configured to be substantially flush with the lower end surface of the engaged claw 24 .

In the conveyance equipment configured as above,
When the drive trolley 1 passes under the front end trolley 15 of the conveyance moving device that is stopped, the engaged claw 24 is moved by the non-return movable member 1 as shown in FIG.
When the slope 11a of 1 collides with the movable check member 1
1 is pushed backward and downward around the horizontal horizontal axis 6 against the biasing force of the weight portion 13. When the distal end portion 11b of the movable non-return member 11 passes forward directly under the engaged pawl 24, the movable non-return member 11 returns to the engagement position due to the biasing force of the weight portion 13, and The tip end portion 11b of the movable member 11 is located in front of the engaged claw 24, and the hook-shaped engaging portion 7 of the movable pusher 5 engages with the engaged claw 24.

As a result, the movable pusher 5 pulls the front end trolley 15 via the hook-shaped engaging portion 7 and the engaged portion 24, and the conveyance moving device equipped with this front end trolley 15 starts moving forward. . In this driving state, even if the conveyance moving device moves forward at a higher speed than the forward speed of the drive trolley 1, it is still engaged with the hook-shaped engaging portion 7 of the movable pusher 5. The forward movement of the engaged portion 24 with respect to the movable pusher 5 is prevented by the distal end portion 11b of the non-return movable member 11 returning to the engagement position.
Therefore, even on a route with a downward slope, for example, the transport moving device can be safely and reliably propelled at the forward speed of the drive trolley 1.

In addition, in a storage line, etc., when the transport moving device propelled by the drive trolley 1 as described above reaches a position where it collides with another stopped transport moving device, as shown in FIG. Rear end trolley 1 of the conveyance moving device in advance stopped state
The pusher operating portion 25 in the drive trolley 1 comes into contact with the slope 10a of the pair of left and right operated portions 10 of the movable pusher 5 in the drive trolley 1.
is pushed backward and downward around the horizontal horizontal axis 6 against the biasing force of the weight portion 8. Due to the upward movement of the weight portion 8 when the movable pusher 5 is tilted and swung,
Movable member 1 for non-return riding on the weight part 8
1 is pushed up, and the non-return movable member 11 also falls and swings backward and downward around the horizontal horizontal axis 6. Of course, before the weight part 8 pushes up the weight part 13 of the movable check member 11, the pusher operation part 24 collides with the slope 11a which is the operated surface of the movable check member 11. Since the slope (operated surface) 11a is retracted from the slope 10a which is the operated surface of the operated section 10, this does not occur. As the movable pusher 5 swings as described above, the hook-shaped engaging portion 7 is switched to the non-engaging position below the moving path of the engaged pawl 24, so that the movable pusher 5 is moved to the non-engaging position. The subsequent transport moving device that has been separated from the claw 24 and has been propelled automatically stops in a state where it is connected to the previously stopped transport moving device.

As shown in FIG. 5, when the operated part 10 is detached from the pusher operating part 25 forward and the movable pusher 5 is returned to the engagement position by the biasing force of the weight part 8, the pusher operating part 25 is operated. An appropriate length is provided so that the hook-shaped engaging portion 7 of the movable pusher 5 comes into contact with the lower end surface of the pusher operating portion 25. Therefore, the drive trolley 1 can smoothly pass under each transport moving device which is stopped in a row in the storage line, accompanied by the see-saw movement of the movable pusher 5.

At the top position of the storage line, etc., the transport moving device is moved by the movable pusher 5 of the driving trolley 1.
In order to separate it and stop it, a stopper that can move in and out and has the same function as the pusher operation part 25 may be used.

(Effects of the Invention) As described above, according to the drive mechanism of the transport moving device according to the present invention, similarly to the conventional drive mechanism of this type, the transport moving device is propelled by the drive trolley without stopping the drive trolley. Not only can a storage action be performed to automatically stop the moving pushers sequentially, but also it can reliably prevent the engaged claws of the conveyance moving device from moving forward in advance relative to the movable pusher. Even on the route, etc., the transportation moving device can be safely and reliably propelled by the movement factor of the drive trolley.
Furthermore, when the movable pusher of the drive trolley engages with the engaged pawl of the transport moving device, the movable pusher is not switched to the non-engaged position by the engaged pawl, so the drive trolley can be moved at high speed. Even if the movable pusher and the engaged claw are engaged, it is possible to ensure the engagement between the movable pusher and the engaged claw. Further, since there is no need to increase the distance between the movable pusher and the non-return portion, the movable pusher can be made lightweight and compact, and the range of back and forth movement of the engaged pawl can be minimized to ensure secure holding. It can be promoted by

Furthermore, the greatest effect of the configuration of the present invention is that when the drive trolley passes under a large number of stationary moving devices in the storage path, the movable member for non-returning prevents the engagement of the engaged pawl of each moving device. Although it is kicked relative to the pusher, it is not kicked by the pusher operation part, so the noise generated is halved, and the degree of damage to the tip of the movable check member with the operated surface is also halved. However, the durability is improved.
