Description

[Detailed Description of the Invention] The present invention relates to a bogie elevator for conveying spools of paan, cheese, etc.

When loading a thread roll such as paan or cheese from a thread winding device onto a trolley using a moving device and transporting it to an inspection and packaging line, multiple pegs b are installed horizontally and vertically to the front and back of the car body a. Using carts A (Figs. 1 and 2) protruding in a staggered manner, the pegs B
The bobbin body P is inserted into the carriage A for inspection, and transported to the conveyor installation position of the packaging line.
The bobbin bodies P loaded on the conveyor are transferred onto the conveyor.

In order to transfer the spools from the cart to the conveyor, the cart loaded with the spools is transported to a predetermined transfer position, held by a fork, etc., raised to the chuck operating position of the transfer device, and then moved to the top stage. A plurality of bobbins inserted into the pegs are simultaneously gripped by a chuck mechanism, extracted from the pegs, and transferred onto a conveyor. When the topmost spool has been transferred, the next spool is raised to the chuck operating position, gripped by the chuck mechanism, extracted from the peg, and transferred onto the conveyor. The cart is sequentially raised by the vertical interval of the pegs to perform transshipment.

The bogie elevator for raising the bogie loaded with the bobbin bogie at predetermined intervals is provided with forks on the machine frame that protrude in a direction perpendicular to the conveying direction of the bogie and are movable up and down; A convex portion that engages with the positioning recess is attached to position the truck and fix the truck on the fork.

However, in the bogie elevator with the above configuration, since the bogies and forks are provided with concave and convex portions for positioning engagement, a large number of bogies must be provided with engagement concave portions, and the existing bogies cannot be used as is, and the existing bogies cannot be There were drawbacks that required a lot of time and money to improve. Furthermore, the positions of the pegs for inserting the bobbins provided on the front and back sides of the bogie change when the bogie is reversed, and the dimensions of the peg positions and the recesses that engage with the convex portions of the forks also vary, so the stacking of the bobbin bobbins is difficult. During replacement work, the trolley could not be held in a predetermined position and raised or lowered, resulting in a gripping error or damage to the bobbin, reducing its commercial value.

The present invention was developed as a result of studies aimed at solving the drawbacks of the conventional trolley elevator.

That is, the present invention provides a frame body that supports the truck and moves up and down along the guide of the machine frame, and a member that supports the body of the truck along the traveling direction of the truck, and a device that clamps the front and rear parts of the truck. , a bobbin carrier that accurately and reliably holds the bogie in a predetermined position and raises and lowers the bogie, which is equipped with a device that clamps the sides of the bogie, a device that detects the presence or absence of the bogie, and a device that detects the direction of the bogie. It provides elevators and escalators.

The clamping and lifting operations of the bobbin in the bobbin transport bogie elevator constructed as described above will be explained.

First, the frame 3 is placed on standby at a position where the cart A can be carried in. Next, the cart A with the bobbin body P inserted into the peg b
is fed into the frame 3 while being regulated in the width direction by the guide 35. The body a of the truck A comes into contact with the roller 8, which is a stopper for determining the stop position, and stops. At the same time that the body a of the truck A comes into contact with the roller 8, a control device (not shown) activates the limit switch 24 and sends a signal indicating that the truck A is inside the frame 3.

As the frame body 3 rises, the rollers 6 provided on the support member 4 integrated with the frame body 3 support the lower surface of the vehicle body a, and the wheels c are lifted to a position away from the floor surface F. When it is detected that the vehicle body a is supported by the rollers 6, an operation command signal is sent to the cylinder 19,
The rod of the cylinder is projected to press the pressing tool 20 against the side of the car body a of the truck A, and the car body a is held between the stopper 18 that regulates the widthwise position of the truck. During the support of the vehicle body a by the rollers 6 and the clamping operation of the pressing tool 20, the trolley A moves on the frame body 3, but it is moved smoothly so that the rotatable rollers come into contact with the supporting part and the clamping part. be able to. When it is detected that the side part of the car body a is clamped, an operation command signal is sent to the cylinder 21, the rod of the cylinder is projected, and the holding tool 22 is lowered to come into contact with and press the top surface of the car body a of the bogie A. , and the rollers 6 sandwich the vehicle body a from above and below. When it is detected that the car body a is held between the upper and lower sides, an operation command signal is sent to the cylinder 27, and the rod of the cylinder is retracted to raise the frame 3 and stop it at the position where the bobbin body P is transferred. When it is detected that the trolley A has moved to a predetermined position, the control device sends an operation command signal to the transshipment device (not shown) based on signals indicating the type of the trolley and the direction of the trolley, and the control device sends an operation command signal to the transshipment device (not shown). The chuck mechanism grips the topmost bobbin body P at the transfer position, pulls it out from peg b, and transfers it to a conveyor (not shown). When it is detected that the transshipment operation is completed, the control device sends an operation command signal to the cylinder 27 to retract the rod of the cylinder until the bobbin P inserted into the peg b of the next stage comes to the transshipment position. raise. When it is detected that the next bobbin body to be transshipped has moved to a predetermined position, the control device sends an operation command signal to the transshipment device to operate the transshipment device and transfer the bobbin body P to the conveyor. When the above operation is repeated and it is detected that all of the bobbin bodies P inserted into the pegs b of the trolley A have been transferred, an operation command signal is sent from the control device to the cylinder 27 to cause the rod of the cylinder to protrude and the frame body 3 lower. When the frame body 3 is lowered to a position where the vehicle body a is supported by the rollers 6, it is stopped. When it is detected that the frame body 3 has stopped at a predetermined position, the cylinder 2
1, the rod of the cylinder is retracted, the holding tool 22 is raised, and the upper and lower parts of the vehicle body a are released. When it is detected that the clamping of the vehicle body a is released, an operation command signal is sent to the cylinder 19, the rod of the cylinder is retracted, the pressing tool 20 is moved backward, and when it is detected that the clamping of the side of the vehicle body a is released, An operation command signal is sent to the cylinder 27 to project the rod of the cylinder and lower the frame 3 to the loading position of the truck A. When it is detected that the frame body 3 has moved to the loading position, an operation command signal is sent to the cylinder 17, the rod of the cylinder is projected, the arm 14 is moved, and the front and rear clamping of the vehicle body a is released. When it is detected that the front and rear grips of the vehicle body a have been released, an operation command signal is sent to the cylinder 10 to retract the rod of the cylinder and rotate the arm 14 from the horizontal position to the vertical position. When it is detected that the arm 14 has rotated to the vertical position, the cart A, on which only one side has been transshipped, is sent out from the frame 3 by a transport device (not shown). The cart A is reversed at a predetermined position, and is again fed into the frame 3 while being regulated in the width direction by the guide 34, and the above operation is repeated to transfer the other bobbin. When the trolley A becomes empty, it is delivered to the empty trolley collection site by a conveyance device (not shown) and the transshipment operation of the spools is completed.

When it is detected that the empty cart has been sent out, and the cart with the bobbin body inserted into the peg has been sent to a predetermined position, the transshipment operation is performed based on a command signal from the control device. The bobbin body inserted into the peg of the trolley is transferred to the conveyor.

Although the present invention can be implemented as described above, it is not limited to the embodiments.

Γ The device for detecting the type (length) of the trolley may be equipped with a plurality of limit switches or photocells and may be configured to detect an operating piece on the rod or shaft of the cylinder for operating the arms of the front and rear clamping device of the trolley.

The elevating mechanism for the Γ frame may be a combination of a cylinder and a chain or a rope, or may be a combination of a reversing motor and a screw mechanism. Also, as in the example, it is preferable to reduce the capacity of the cylinder for lifting and lowering the frame provided with a balance weight.

Γ Confirmation and operation commands for each operation of supporting the cart and raising and lowering may be performed by a control device consisting of an operation memory circuit, an operation command circuit, a detection circuit, a judgment circuit, etc., and a detection device such as a limit switch or a phototube, a timer, etc. This may be done by switching the fluid supply circuit to the cylinder.

As described above, the present invention provides a frame body that supports a truck and moves up and down along the machine frame, and includes a member that supports the truck along the traveling direction of the truck, as well as a front and rear clamping device for the truck, and a side support for the truck. By arranging a part holding device, a truck presence/absence detection device, and a truck direction detection device, the following effects can be achieved.

Γ Presence or absence of a trolley and direction of the trolley (front and back of the trolley)
Detects this and activates the clamping device of the trolley, as well as raising and lowering the frame supporting the trolley. This allows the trolley to be held at a constant position reliably and at all times. This prevents problems such as incorrect gripping of the bobbin body.

Γ Even for carts with different pitches for inserting spool bodies, or for carts with different peg positions on the front and back sides of the cart, there is a device that detects the direction of the cart and the type of the cart, so the chuck mechanism of the spool changing device can be used. It can be moved accurately to the gripping position and the bobbin can be reloaded reliably.

Γ Since the carriage is held by a carriage support member and a clamping device provided on the frame, there is no need to provide an engagement member for positioning on the carriage, and the existing carriage can be used as is. Furthermore, if the positions of the pegs for inserting the bobbin winding body are different on the front and back sides of the cart, any type of cart can be used by simply providing an actuating piece for identification.
